Question- GSR head on my b18c5 ITR block
I've searched for this scenario with no luck, can I get some help.
My ITR head was recently stolen off my stock B18c5 bottom end in my 1995 Integra GSR OBD1.
I have my old stock GSR head complete with intake manifold and throtle body ready to bolt on. I understand that this will not be as good as my old set up but i need to get my car back on the road and money is very tight so...
<U>Questions:</U>
1. What would my approx compression be?
2. Which ECU do i need?
2. Are there any issuses or concerns I need to be aware of?
3. Any other advise?
Thank you in advance.

your compression will be about 11.5 11.6ish. the only difference between the c5 block and c1 block are the pistons. you could probally use a p72, but would be better off with a chipped ecu. other than that you should be fine. sorry to hear about the theft. good luck.

If the head is stock just put the stock P72 back in there, you got a knock sensor so no need to get too worried about the upped compression. Not to be argumentative towards the previous poster, but I don't see how reducing the chamber volume by 1.1cc is going to up the c/r by almost a whole point. If so just run premium fuel until you can get it tuned or whatever.

yeah i was thinking about the p73-00 pistons( jdm itr). i think you comp ratio will be more like 10.8
