Surging & losing power at crusing speeds, ????

I was just thinking that. How much is it? And do you have any already done so I don't have to be without a car? My capri is my only transportation.    Thanks!

They're $250, and yes I have several ready to go. Look into getting exhuast/intake first

For now can I add a boost controller? If so what should I set it for? And what plug am I supposed to unhook? I lost the thread it was on.. LOL..

Hey Randy! Don't unplug the over-boost until you get the Rocket-chip. It is a unit mounted on the fire-wall directly behind the fuel unit of the engine.  Gus

dont get a boost controller either until you have a boost gauge, air fuel gauge (optional), intake and exhaust. factory settings are fine until you get those supporting mods.

Hey Gost!  Factory boost gauge will work but I'm definitely with you on the AFR gauge, one may have kept me from burning a motor. And 21/2 inch exhaust will surely allow the motor to breathe and modifying the intake box also, to allow more air.  Gus.

Hey Randy!  I forgot to congrat you on finding the problem. Yes the fuel pump is easily accessed by taking the rear seat bottom out. Real easy!  Gus

i would never trust the factory gauge for anything more then factory..just think this gauge was made in the late 80's way before people thought about doing to them what we are doing..it was nothing more then eye candy for owners.

Hey Gost! I'll agree over complete accuracy, but I'm thinking necessary priorities. I guess we all have opinions.  Gus

The stock boost gauge I have found to be accurate to only about 10psi...and it will vary from car to car. My first XR2 was dead on till 16..my second XR2 was off the scale at 16psi. It just depends.

So yes, aftermarket boost gauge is very important IMO, and if you're going mod crazy Wideband O2 is way up there too.

You CAN install a boost controller, it will decrease your spool time without necessarily increasing boost, you just have to adjust it carefully. Cory (pmpsht) makes Tunerfixx manual boost controllers, they're a wonderful bit of hardware.

If you do happen to install an MBC, and then go for intake and or exhaust, be sure to re-dial it from zero because the free-flow of the new parts will affect the way and the levels to which the engine boosts by itself.

Hope this helps.

Ok, I have bought a Turbonetics 0-50psi boost controller, and a cone air filter with adaptor plate for the VAFM. I am looking at air/fuel meters, and found this one: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=390058833993

Can anyone tell me how these hook up?? I assume to the O2 sensor wire?

That particular air/fuel meter is a narrow-band system. I woulded really recommend getting one just because there inacurate and all over the place. Your gonna want a wide-band if you plan on really keeping your eyes's on the AFR. There a little expensive but there by far worth the money. Just my two cents.

Hey Randy ! I think co-co is like myself, fails to proof read before sending. I believe he mean't to say not that one. It is best to get a wide-band. Short band will show AFRs but in a delayed moment. Wide band will get the AFRs as they are occurring, best to have. The wide bands are expensive but when you're putting a car together you don't want to burn down a motor, more expensive.  Gus
