Ok, so here goes.
I have a 91 Honda Crx Hf 5 speed, nice car but when I bought it, it came with a jdm Si motor. The engine plate doesn't have anything on it but everything I find leads to d16a6, single cam, non vtec, fuel injected, Si motor swap ordered from HMmotors, if that's how its spelled, with 50k on motor, I seen the receipt.
Having said that, I have a nice y8 head and intake I went and bought along with a p2p manual ecu to attempt to complete the head swap and still stay d series.

This is where the questions begin:
obviously everyone on this forum knows my car is OBD 0 and the head is OBD 2 would it be easier to run with a p2p ECU or a p28 which is OBD 1. I ask this question because a friend of mine told me it is much easier to run OBD 1 then OBD 2. if this is the case then can someone please give me a possible list of what exactly I would need to successfully complete this swap, if its even possible on a d16a6 block, or if its even worth the time.

Everything on the CRX right now is OBD in case someone is wondering or has questions on the set up that I am running.

 

0BD1 1000 times easier

 

My friend really wants my a6 head which is why he wants to help with the swap so badly btw, which is weird to me because I thought the y8 head was better but if there's an unknown reason for this someone please point it out to me.
