Hey I'm about to put a z6 in 1990 crx si an was wondering what I'm gunna come across in order to make it run perfectly "0 codes" I have the z6 engine harness also an p28 ecu with obd0-obd1 jumper. just need to know what mounts to order an what wire changes am I gunna need to do an do I need to change anything for a resistor box?

 

Use the obd-0 injectors, cable trans and prepare to wire vtec and 02 sensors. You can also chip the ecu and turn the o2s off.

For the mounts you can reuse the Si mounts just swap over the timing belt mount (bolted to the block) from your old motor to the new. Reuse your axles. You're also going to need to use a distributor adapter and use the Z6 distributor as well. The fan switch will need to be extended from the back of the block location of the A6 to the thermostat location of the Z6. The rest should be plug and play using the Si harness. As for VTEC and O2 wiring:

 

I don't have the old motor or trans so don't have old mounts so well just order stock mounts for crx si correct? but the harness from stock motor still in car I don't have stock injectors that came with car I have the stock ones on the z6 though I thought they were better since there newer

 

I also already have a cable trany to match motor so not doing hydro.

 

if u ever need a bad *** lsd trans for that car i have one. its cable too

 

How much cause I'm not lasy if I wana build mine ill just do it have my own shop.

 

You don't need the mounts just the timing belt mount that bolts to the block, junkyard or Honda

 

You must remove the resistor box to use the z6 injectors, it is not hard. You will have to change the connectors for the distributor as well.

 

what wires are they for removing resister box an dont i just run them into eachother?
