B20/vtec into 86 CRX SI

[CRXSi86]

hey guys, im buying a B20b block with a b16 head, ecu, vtec harness... i know i will need the axles hub and brakes, engine harness, shift linkage, and mounts, and the main and rod bolts and head studs, anyways,....


is this a real complicated swap, what else will i need to do, im trying to find out all the info i need, i also need a tranny, if you guys know what kinda tranny fits best or is the best for this, that would be great, thanks

Anyone???

Transmission- B16 has the best gearing, plus it's cable actuated.
Needed to roll- Axles, Mounts, Shift Linkage
Needed to drive- harness that will work(don't know much about 1st gens), obd-0 to obd-1 jumper harness for the ECU (if you want tunability and VTEC).

Should get you started anyway.
I don't know if this is a bolt in process or what, but like I said, I'm not really familiar with 1st gen swaps

yeh im bringing my harness to rywire.com, and they will do the full conversion for me to OBD1 for a plug and play harness. im not sure what ecu i should get, i know i need something that will be chippable to dump enough fuel, but thanks for your help,



if anyone else knows anything, it would be greatly appreciated.
