Hey hey! This is my first time posting here but i've been doing quite a bit of reading to catch up on the B-Series engines for a while, and some doubts popped up along the way.. Hopefully someone can help me out or point me in the right direction? Well, i'm currently eyeing a 91 CRX with a B16A (european).. The owner claims it's fully stock and I don't see any evidence otherwise, however it's got circa 100K miles on it's engine. Since the pricing is pretty decent and the interior/exterior is almost mint I thought this would be a nice project to delve into Hondas and was thinking to rebuild that little engine for up to 175 to 185 whp NA, mostly with OEM parts and a couple aftermarket boltons. BTW, in my country we use 95 octane. So, this is what I had planned: - CTR cams OR Skunk2 Stage 1 cams? - CTR or ITR valvetrain - ITR intake manifold - ITR throttle body (62mm) - ITR exhaust headers - CTR pistons/milled stock rods/OEM 3L head gasket OR JDM P30 pistons/stock rods/2L head gasket - AEM CAI intake - Custom 2.5" exhaust with sports cat - Hondata s200 w/ tune I'm also thinking of replacing the usual maintenance parts and all that, but what I really wanted to know is if it is a good selection to reliably meet my power target and remain street legal in terms of emissions? I'm intending to go for a rev limit between 8500 to 8900. Also on the underlined points I presented 2 choices, which one would you think I should go for? Am I gonna be safe on valve clearance and such? Should I consider sleeving or any other special procedure like head porting for a project "as lowly" as this? Thanks in advance for your help and sorry for the noobish questions!
