Default 91 CRX Si w/b16a also with t3/t4 turbo to 91 Civic STD

Ok here is my situation....My friend want to sell his setup and he is going to part out his car.....I am going to by all of that stuff.....I just want to know if everything will fit in my car.....Will the seats fit in my car without any modification? If so what do I have to do? I know the complete swap will fit with no problem. Will the crx mounts work for my car? Has anyone else done this? About the rear disk brakes, will they covert onto my car? About exhaust. will it fit? From what I heard, since the hatchback is a little shorter then the crx, the exhaust will be a little too long, but will work with a little modification. But the are both built on the EF chassis. So everything should swap over right? Let me know any feedback that you can give me on this. Thanks.

I believe that the seats will fit and I know that the rear trailing arms will. Don't forget that if you swap into a Std you need hubs/knuckles from a DX or Si hatch, bc. otherwise the axles won't fit.

seats fit with no modification
the CRX mounts will work for you....
the rear disc its a bolt on.... u gotta use the Si ebrake... follow this..
the exhaust i beleive the CRX its shorter... maybe if u have a welder and a liul piping from autozone u can make it fit....

The hatchback is NOT shorter than the CRX. I know from personal experience, swapped an exhaust from a hatch to a CRX. You'll have to add somewhere in the nieghborhood of 7" to the main straight section of the CRX's exhaust.

Also, you'll need to do a DPFI to MPFI wiring conversion, and add VTEC wiring to the STD chassis

Well do the 91 crx si's have MPFI? Because I am buying everything from my friend. I am getting everything except the shell and some of the interior. Let me know. Thanks.

Yes, but it not something you buy/aquire. MPFI stands for Multi Point fuel Injection. Si/HF's use 4 injectors and a few extra senors. The DX/STD's use Dual Point Fuel Injection(DPFI), also know as Throttle Body Injection. DPFI/TBI only uses 2 injectors, thus you need to change around some of the wiring at the ECU and in the engine bay. You have to add one peice of equipment, the injector resistor box. You'll have to ****** it from the Si's engine bay, it's back by the right side of brake master cylinder. It's 3"x4" or so, gray, and has heat sink fins on it.

The process is not that hard, just make sure you take your time and make sure you 2x and 3x your work. Also, soldering is the best way to do wiring work, crimp connectors can fail and corrode. If you need some instructions do a search on H-T, or visit the how-to section of my website, and look in the swap section.
