Title: 91 XR2 build thread (SIQ XR2)
Post by: icurunnin on August 26, 2009, 04:04:00 PM
So for starters I am showing the stock pics I have of it and will update as I go along.

Well today's progress went pretty well. I installed the HKS SSQ and it turned out pretty well.

I also installed my blitz super street boost controller. I put the control unit in the glove box out of view for when the tops down. I installed the black box (brain) on the passenger side kick panel on the left.

I also drilled a hole in the firewall next to the throttle cable to run my pressure line for the brain, pressure line for the gauge, and wires for the boost solenoid.

tomorrow I am going to finish the wiring and making it all look stock and clean. Once I get it all together I have to figure out where to mount the boost gauge, and get my Rocketman chip to crank the boost up.

Pics to come tomorrow

Well I never finished the boost controller or the gauge install and jumped right to the intake. Reason being that I dont trust myself enough to have a EBC with no Rocketman chip or the gauge pod for the gauge.

So those things will be getting ordered today.

Here are the pics of the HKS SSQ I installed. I used a HKS adapter as well to hook it up to the stock pipe until I get the aftercooler pipes made.

Works just like it should and sounds mean even at 6 psi. LOL

And no it does not rub anywhere and has pleanty of clearance.

Next up is my intake install which I have taken a few pics of in case someone here like the way it came out.

First remove the intake box, and upper intake boot.
Next unbolt the coolant resevoir and place it aside. This will be relocated to clear the filter in the stock location.

Next remove this bracket
 (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829090824.jpg)

Now get a straight piece of metal ( I recommend 1/8" at least) that is pretty stout.

Drill two holes like shown below for the coolant resevoir.
 (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829090842.jpg)
 (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829090842a.jpg)
 Now use one of the stock bolts removed from the bracket you removed earlier and use the bolt hole to the left of the resevoir to bolt in place like so.
 (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829090843.jpg)
Should have some empty space now like shown

Post by: icurunnin on August 29, 2009, 10:43:00 AM
you will have to cut the outlet hose to keep it from hanging down past the air dam. looks like this all hooked back up.
 (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829090850a.jpg)
Next bolt your MAF adapter up tp your stock MAF meter. I bought this off egay for $10 shipped.
 (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829090851.jpg)
Now I didnt get a picture of the next bracket but you will know which one I am talking about once you see the pics. It is the bracket that bolts up next to the battery and has a stud sticking out of it for the factory air box.

Break the stud off and drill a hole thru it.
 (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829090854.jpg)
You will now have to take the angle grinder or dremel tool out and hack a small section off so it bolts up to the coil. This is not a must for everyone but I do not want zip ties holding my ignition coil to something or just letting it hang somewhere.
Here is the section I chopped off.
 (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829090909.jpg)
You will use this bolt and nut that was originally used to hold the coil to the air box.
 (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829090857.jpg)
Here is what it looks like installed.
 (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829090915.jpg)

Post by: icurunnin on August 29, 2009, 10:50:00 AM
I bought the $20 spectre air filter from autozone since it was shorter and not as wide as the $25 one's that come in different colors.
  (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829090851a.jpg)
I did not take pics of the bracket I made but you can see the two bends I put in it to keep the filter and MAF from flopping around and looking ghetto.
  (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829091535.jpg)
  (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829091536a.jpg)
I also installed new front strut mounts as you can see. Driverside had no bearings and had fallen apart long ago. passenger side wasnt bad at all and only had a little slop in it.
  (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829091601.jpg)
  (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829091601b.jpg)

I also installed the Apexi solenoid and just need to run the vacuum lines once the boost gauge installed.
  (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829091602.jpg)
  (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0829091602a.jpg)


All in all I liked how everything came out today. It doesnt look pieced together and keeps the MAF in the stock location. Later I will update with some mandrel bent pipes for the intake to replace the stock plastic and rubber piece.

Once the Rocketman chip and gauge pod get here I will update the thread with some more pics.

Hope this helps someone since there is not to much "how to" around these wood.

the guy i had make my intake pipes told me today when i picked up josh's that he would be willing to fab things for us. so if you want an aluminum pipe for the throttle body and J pipe let me know. he is also willing to make manifolds as well. i plan on getting him the stock examples soon to make one.

well today went pretty well. I received my parts from Gostlrs today. I installed the driver side foglight backing and the whole unit.

Also installed the driver side headlight motor and it works great.

I had a set of stock wheels off my old 92 GVR4 that I plan on throwing on the XR2. Degreased them and getting them ready to be sandblasted and touched up. They will be getting the common flat black theme with a thin red stripe down the center of each star.

I love builds, theese cars , and race gas smell...aaah

here ya go ICU, remember 2-1/2 years ago i started with the same exact 91 cardinal red xr2 you have there... heres some motivation...this is what a 12.999 looks like in a capri...

Post by: icurunnin on August 31, 2009, 04:19:00 PM
you squeezed a 12.9 out of your current 14b setup? That would be great for a daily driver which is what mine is.

Only problem I will have is that I am keeping my a/c unlike most here. That will create an issue when fabbing everything up on mine as compared to the setups shown here.

Texas heat isnt a joke and I HAVE to keep my a/c and power steering so I am sure my car will be slower than others.

I plan to do a fuel pump re-wire on the XR2 like most DSM'ers do to get more voltage and output out of the stock pump. I just added up what I spent on this thing in the past two weeks and its getting out of hand. LOL

I have the Rocketchip with ECU on the way and my 1.5" to 3" reducer to get crazy better flow over the stock unit and the intake I already have.

Looking forward to install the ecm, boost gauge, boost controller, and fuel pump re-wire to start having some fun with this car.

Post by: rcicustoms on August 31, 2009, 04:56:00 PM
um no, i squeezed a 12.80 out of my current setup
im running about a 9.2-1 compression with a 14b at 18psi and every support mod available to be done to it...suspension, brakes, wheels (15 lb. 5zigen japan) tires (bfg g force)..

i have removed the a/c , power steering , front and rear bumpers, all airbag crap, all seats, (replaced the front with lighter racing seats with harnesses) everything out of my trunk..
(thats where the redtop optima resides)

i have a basic cd player with 4 speakers and tweeters... no subs or amps or anything heavy...

the car is now sub 2300lbs 12s are not easy to get to ..i fought my way there with research and drive to do so...
 i smash evo 8s, wrx.stis, porsches, older vettes, mustangs, camaros, to an extent.. you can make a stang or marro run 9s if you want but most people that buy the mentioned cars dont mod them much .. who has the money to mod a 40,000 car??? besides void the warranty... ive beat a mazdaspeed 6 and a mazdaspeed 3...(3s are a bit quicker)...

now ive had my ass handed to me by a built civic ls v-tech, a 10 sec fox with a pro-charger, and an integra ls turbo...oh and my buddys cobra mustang... (its a 12.3 car) my buddy bryan smith put one of our b6t motors in a festiva and ran a 12.5, he was faster than me with less done to the engine but weighed about 1600lbs...

but yes im in the 12s and i drive it to work every morning ...rain, shine, snow, it dont matter.... its MY only car....

how do you do the fuel pump rewire and what does that do ?

joshua , did you send me a friend request on facebook?  i accepted it...if thats you....
Title: 91 XR2 build thread (SIQ XR2)
Post by: icurunnin on September 01, 2009, 12:45:00 AM
joshua, a fuel pump rewire consist of adding larger gauge wire like a 10 gauge for amp's from the battery straight back to the fuel pump. what this does is increase voltage to the pump which increases the output of the fuel pump.

it really helps up top (higher rpm's) where the fuel pump starts to drop volume and pressure. I will do a write up on mine and take some pics for you. a fuel pump re-wire is a must if you own a dsm but also helps every other car out there.
Title: 91 XR2 build thread (SIQ XR2)
Post by: Heavensheros on September 01, 2009, 04:17:00 AM
ok and also thinking about getting that resistor pack thing that you did. also i kow it sounds dumb but what does dsm stand for ?
Title: 91 XR2 build thread (SIQ XR2)
Post by: rcicustoms on September 01, 2009, 06:13:00 AM
you only need the resistor pack if your going to run "low impediance" or "peak and hold" injectors
otherwise it is pointless...

and DSM stands for Diamond Star Motors.. and it truely stands for the first generation eclipse, talon, laser, cars... after that dodge got there hands in the mix and it became mitsubishi motors
but all mitsubishi is often refered to as DSM...

Post by: icurunnin on September 01, 2009, 06:23:00 AM
Hey Joe I got my hands on a set of DSM 450's but really thinking of using the t-bird's just to see how well they hold up.

I know the 450's will have enough but I am kinda iffy on running the lower fuel pressure to get it to run decent. Plus I know you said its pig rich up top with them.

The 450's are on their way here so I guess I will just keep crunching the numbers in my head to see what plays out. If I dont use the t-birds I will let you know since you were interested in finding some.
Title: 91 XR2 build thread (SIQ XR2)
Post by: rcicustoms on September 01, 2009, 06:40:00 AM
well it runs pig rich down low and below 4,000 rpm..up top im seeing 10.0-12.5 on my wideband witch is rich, but safe rich, not flood rich... but yea im running about 28-32psi of fuel press.
witch is not real low but stock there 35-40psi..

yea keep me in mind on those injectors...you shoulda told me ida traded the 450s for the 390s for a bit...Joe

ever thought of trying to good ol Apexi AFC to tune your car to its best potential?

I bet you could squeeze at least 10-18whp out of it.
Title: 91 XR2 build thread (SIQ XR2)
Post by: rcicustoms on September 01, 2009, 06:49:00 AM
it wont work becuase our VAF uses some weird 5-11 voltage signal instead of the normal 1-5.or whatever i just know it wont work unless you switch to the BP stuff and then you might as well use a haltech or a megasquirt so you can adjust timing curve too..
Title: 91 XR2 build thread (SIQ XR2)

ask rocket he can explain it beter than i can... i just know the signal is not normal becuase i wanted to use a greddy e manage and couldnt cuase of my VAF and the signal the ecu uses...

Yeah I am in the same boat.

put the capri on the lift yesterday and was inspecting everything underneath it and it all looked great.

 I was looking at getting a downpipe made and it doesnt look like it would be real hard at allto get a 2.5" downpipe in there without having to trim the oil pan.

guess I will have to wait and see though.

Post by: Rocketman on September 01, 2009, 02:34:00 PM
Our airflow meters run a 7-9 or a 0-9v sweep, its been a while since I looked into it the info is in an old thread around here somewhere.

The AFC's are compatable with 0-5v VAF,MAF signals only. The AFC would not be able to tell the ECU properly what position the VAF is in when it cant provide full sweep voltages.

There was a guy in NZ making GM hotwire MAF conversion kits, it used the 3" MAF and then a mini-computer with a lookup table to emulate the VAF. Supposedly worked pretty good, I dont know if they ever finished making kits though. IMO its much easier in that point to wire in Megasquirt because the AFC and a MAF conversion are only bandaids while you can get some serious stuff done with MS or other standalones

hey rocket are you still working on the ecm values looking for new tunes?

have you tried adjusting fuel injectors values?

have you talked to other programers who do ecm tunes?

I know Keydiver from the galantvr4.org board does a lot of DSM burns and has done quite a bit of options on his tunes.

Would you be willing to get in touch with him to maybe look into some more tunning options?

Post by: icurunnin on September 03, 2009, 12:50:00 AM
well the f.a.s.t. 1.5"-3" reducer came in yesterday so I was busy configuring the new setup.

I ended up with just one 45 degree bend up towards the coolant resevoir and and the rest is straight to the turbo. also moved the coolant resevoir back to the stock location.

it was dark out so I will get pics of it today if the rain stops. this has to be the best flowing intake possible for these cars considering it only has one reducer (a must with any setup considering the size of the turbo inlet). one 45 degree bend (not sharp 90's) and a straight shot into the turbo from there.

total for the setup is as follow
3"-1.5" f.a.s.t. reducer = $28
spectre air filter = $22
3"-3" silicone coulper = $8 x2
45 degree bend = $12
Vaf 3" adapter = $10

will get some pics this evening

Well I made some progress today. I went to the junkyard and got myself a resistor box and iac motor.

Also had time to strip the powder coat off the gvr4 wheels and center caps. here is what center caps will look like when I am done shaving them. I am also going to touch up the wheels from the light curbage that the previous owner so kindly did for me. it's only one wheel so its not to bad.

after I finish the wheels I am going to start on the resistor box and buy some o-rings for the t-bird injectors. The smaller resistor box with the heat sinks is the one I will be using. The other two are up for grabs.

Finished shaving the center caps and leaning up the lips on the wheels. They are cleaned and ready for paint.

Also pulled the stock injectors and started comparing them with the t-bird's to see what all was different. I am going to buy the pintle caps that are stock style which are in front of the black injector. They also use a isolator instead of o-rings so I will also use those. bout to start looking online for all that.

You can also see the clip guide that you have to shave off like rcicustoms was talking about with the DSM injectors.

  (http://i3.photobucket.com/albums/y80/icu_runnin22/91%20Capri%20XR2/0907090941.jpg)

next on the list was wiring in my resistor box that I pulled out a prelude. not going to go step by step but you can follow the pics and put it all together. that and I dont want to take away from Joe's write up. It came out real nice and looks all stock.

not bad with the intake set up. How are you going to secure it in place?

well I have installed the DSM grey top 390'cc injectors over the t-birds. also installed new o-rings on all the injectors.

finished up the blitz ebc install and tuning it. it is out of site so when the top is down people dont see it. Its really nice to have 3 boost settings at your finger tips. stock (when ebc is off), low boost (10psi for now), and high boost (15psi) to choose from.

also installed the boost gauge and now I need to order the gauge pod from Lotek and a wideband.

still need to finish up the other two wheels and buy some tires to give this car a much better look than stock.

Just ran compression numbers today and have to say I am happy with the outcome. Doing a compression test on a car is nerve wrecking considering the outcome could be fatal.

drove the car around to operating temp and pulled the plugs immediatley to run the test. All numbers were done dry (no oil added), 10 rotations, W.O.T., and 4 test per cylinder.

#1 - 160 psi
#2 - 153 psi
#3 - 156 psi
#4 - 157 psi

They are within 4% of each other which is a healthy engine with 136k miles.

off to the next things that need to be done.

good compression, its healthy .. on to ways to make its health drop in the name of power...LOL

Thanks Gus! I was really happy with them considering when I installed the ebc that my low boost was 10 and I was screwing with the high boost at 15+ on the highway. That was without rockets chip so I got nervous after a few runs and switched back to low boost.

I hear all these horror stories of melting things past 12psi and didnt want to be a part of that crowd. After inspecting the plugs and the compression check, I am good to go. I am sure having the added fuel from the 390's saved my ass in high boost mode.   ;)

Hey ICU!  I would have to imagine the larger injectors did help save you. Don't chance it anymore, Melted piston happened to me. I was lucky as a complete fresh motor showed up on Ebay at that time. $605 to my door from Texas and about two months of hemming and hawing; Janis was back on the road. She runs strong ready to stretch her legs when a competitor sneers at her.  Gus

it did ... its just like cheap turbo of a civic...we've had the civic we built at 16psi with a stock computer and just the 300cc injectors.. we had turned the fuel pressure up 15psi or so and we were lean as all get out but didnt pop it due to the extra fuel...

i also ran my capri, on the first engine, back a few years ago... before i put the ecu in the car
at arround 14psi with nothing but a walbro pump.
so there again i had no idea how lean it was. i didnt realize the car couldnt do over 12 stock
and drove for months on 14psi... the damn thing was quick, but thats prolly what started the downfall of the first engine....

aah, hindsight is 20/20, and if i hadnt blew the first one at 21psi with stock injectors... i wouldnt have built the high compression...  :D

Hey RCI! It's an old story. That's why I hound newbies about the AFR gauge when they start talking mods. I don't want to see others go through what I've been through.  Gus

Post by: icurunnin on October 02, 2009, 01:37:00 PM
well my next thing on the list is a wideband but I got the guy with the hardtop to take $225 so I am torn between the two. with winter coming I am leaning towards the top for now and just keep the boost at 17psi with my rocketchip.

once I get a bigger turbo I will get the wideband then. I know these injectors are good for the maximum amount of boost this turbo can dish out. Just my .02

Hey ICU!  Get the hard-top!   Gus

Post by: icurunnin on October 02, 2009, 04:14:00 PM
I plan to. I am going to try and meet up with him tomorrow some time and throw that bad boy on. He said he has the special wrench too.
Title: 91 XR2 build thread (SIQ XR2)
Post by: rcicustoms on October 02, 2009, 05:16:00 PM
id get the top and wait on the wideband....
if you run under 18psi, and already have 390cc injectors on any vj turbo your fine....
when you go over 400cfm with the turbo you need to know whats going on... and even then put a fuel pump on it ... and monitor whats up, and you will be fine...

hey, ive been meaning to ask ,did you ever do a fuel pump re-wire???  any difference in performance, or change at all???
Title: 91 XR2 build thread (SIQ XR2)
Post by: icurunnin on October 04, 2009, 05:58:00 AM
I bought the hardtop yesterday and its in decent shape. It has a few small dings on top but it has to be painted anyway so they can fix all that. The headliner is hanging too. Nothing to major for the price I guess.

and Joe, I did not do the fuel pump re-wire as of yet. With the 390's installed I highly doubt I need the extra fuel. Once I get the intercooler, and exhaust done and 17 psi then maybe I will look into then. going to get the wideband and if I start to lose fuel up top I will throw in the walboro and if I still need more fuel I will do the re-wire.

I have a million other things I want/need to get done before I worry about not having enough fuel.

Dude- that is sweet, lots of good info and pics! I can't tell you how excited I am to start this build. The guy I got it from really did a fantastic job on keeping it original and clean. I'm gonna drop it, put some sweet rubber on it, put the body kit on it, and make it fast. I will keep taking pictures also.

thanks for the compliment. I have some more to upload today.
I am at my daughters game right now but will upload the pics later today. I am installing my LoTek dual gauge pillar pod at the moment. Also have to change out my distributor cap and rotor.
found that my cap is in worse shape then I thought. It has lots of corrosion and a few cracks inside. thats probably the reason my car starts to break up sometimes at 14psi on the top end.

we will see soon and I will load those pics of the pillar pod as well.

Here are what changes I have made. Not to bad for $58 shipped and painted to match. You can buy one for $8 less if you wanted it in plain black.

It fits tight to the dash but I dont mind considering how o.e. it looks.

Just did a little ugrade to the stock fog lights. I did this to my old Saturns and didnt have to use the headlights at all. All you have to do is remove the deflector inside the housing and put it all back together.

As you can see there is a big difference between the two.
tabs to bend out to remove the deflector

stock fog light. notice how dark it is on the body of the car verses the upgrade.

Does that gauge pod fit over the OEM piece or does in replace it ergo the holes and pins? Looks like it would work on the 323 also
Thanks

I left my stock panel off and it still rubs the dash a little so I would say it goes on alone. It came with a instruction set that said some light sanding may need to be done to get it to fit 100% but I was just in a rush to mount my boost gauge and threw it on.

Once I get the wideband in I am going to take my time putting it together so it fits better and doesnt rub the dash. Their work is grade A in my book considering how cheesy it would look buying those generic ones and mounting them to the stock plastic.

Hey ICU! On that pillar pod, where did you get it. It appears to accept two different gauge sizes. We had a forum member about three years ago do a group buy. Gus

Received the wideband today and my stock chip to start the tuning process of the 390cc rocketchip.

gonna get the 2.5" turbo back exhaust done in a week or so and going to have the wideband bung welded in then.

just had a 2.5" turbo back installed today and next is the wideband install. Then I will finally do the damn clutch and buy another hard top.
