Turbo swap from 91 to 93

(1/3) > >>

1991 to 93na turbo swap:
Hi guys,
 I'm new here but I have had a 1993 Capri n/a for a few years. Great little car and I love it, however it blew an oil ring earlier this year and I rebuilt he engine (all stock parts) and it's wonderfully happy now. Then after I finish the reinstalling of the engine I found a 1991 turbo Capri in my local junk yard (no title. Only parts car). I want to keep the engine I just rebuilt in my 93 but I would like to swap the turbo over to my 93. Any advice and help would be wonderful. Mostly wondering about the compression if there is any difference between the 93 na and the 91 turbo and if the ecu is just plug and play or if there might be any other unforeseen problems. Thanks

NomakeWan:
The N/A engine has a different computer, smaller fuel injectors, different pistons (which is what give it the 9.4:1 compression ratio, as opposed to the XR2's 7.9:1 ratio) and different camshafts. The transmission that came in your N/A is also not nearly as tough as the one that came in the XR2, so you'll probably want to swap transmissions as well.

so id be better off swapping the motor got it. Do you know if I would have to re do the whole wiring harness for the rx2 ecu to fit? Thanks for the help!

Never mind. Thanks for the help found it in the link you gave me

What You Need:
Engine Harness
XR-2 Sensors
XR-2 intake with fuel injectors
Pedal box, and cables
turbo lines
XR-2 Transmission with the half-shafts
Intercooler, and all piping included
XR-2 computer


Things to note:
You're base Capri engine has a higher compression ratio I believe its 9:1 over the XR-2s 8:1, but im not exactly sure on the ratios its been too long. Just be careful with how much boost you throw at it, because higher compression ratios cause detonation. Also the reason you need the sensors and the XR-2s engine harness is without it the engine will not run, or will have the check engine light on.
In the long run it might be cheaper to just buy a XR-2 unless you want to be a bit unique.
