I have a 97 Civic EX with no motor, sitting in garage is the stock D16Y8 and rebuilt stock H22A4 with all the hardware for the swap; except the ECU which I'm not certain what to use, ODB1 or 2 and what wiring harness to use(I believe it's my stock EK wiring harness, I know I have to extend a couple wires, please correct me if I'm wrong or give me some guidance or link for reference.------- What will you do? My options are: Slap the stock H22, I know it will be a headache with the wiring or forge the D16 towards 11:1 comp ratio. Note that both options will be using wet nitrous, 100 shot for stock H22 and about 125 to 150 for the D16. Need your inputs, I'm indecisive!

 

I would just throw the h22 in it, if you have everything for the swap why not?.If you decide to go with the h22 just get a p28 and chip it!!!.(now about the wiring there's lot of info in here just search!). But then again its your car do what you think its best and most important , your budget.

 

N/A you'll hit the limits of the D before the H. 600cc is a pretty big difference.

 

1) displacement
2) potential

H22... no brainer.

 

H22, Neptune RTP on a p28/p30/p72, Blacktrax will do an awesome job of stuffing everything in there.

I'd only keep the d if you were going to go turbo.
