A qwik winter project

[SiRed94]

Hello to all – was wanting to know if I could get some help – starting a project any advice will help..

Currant vehicle 1990 civic d15b 4 spd
Parts collected for swap
d16y8 block with flywheel – d16y7 head & intake – 91 civic si 5 spd trans with new clutch assm – 91 civic ex knuckles complete with rotors and cali’s – 90 integra rear trailing arms complete with uca and lca –

my question is – im sure I need a different ecu – which one ? – when installing the si 5 spd trans is it a plug and play or do I need more items ie shifter cables or linkage ? axles ? is there anything else I should pickup for swap – thanks for any help that might come my way …

The transmission will bolt on fine without any issues. They have the same bolt pattern and the spline count is the same on all 89-91's. The axles, mounts, linkage, and clutch will all work. As far as the engine goes, just use the original driver's side engine mount and put it on the Y8 block.

As far as ECU goes. If you have a DPFI (2 injector) model Civic, you will have to convert the car to MPFI (4 injectors). I will just explain the cheapest and easiest way to do this swap. It would be to get everything in the car, keep the car OBD0 and do the MPFI conversion. Get a PM6 ECU (CRX Si/Civic Si/Civic EX) and D16a6 distributor. Also, if you can afford it, I would get either a y8 or z6 intake manifold. You can use the injectors from the 92+ civic manifolds and you won't have to wire a resistor box in. This way, you will only have to run 4 wires into the engine bay. If you convert to OBD1, that is just extra work/wiring, and more money.

Just shoot me a pm if you have anymore questions. Later.
