Hi there, I'm from the UK but I am coming to you guys for some much needed advice...

I have a Honda CRX Del Sol with a B16a engine but I am changing it to a B18... I am currently in search and have come across a B18c4... (the euro version) and apparantly it is 170bhp (roughly)....

Although I have heard the b18 and b18c5 which are supposed to be more around the 197-210bhp mark...

I would be happy to go for the B18c4 as I have found it, but to get it to the b18 or b18c5's performance would it just require one of their ECU's or is there differences in the engines themselves? I would really, really appreciate the help and I am now confused and clueless...

Thanks all
