Hi i am a owner of a b18c1 93 civic ex and i have just got myself a jdm sir2 intake manifold, i am almost done portmatching it and have runes 1,2,3 all polishd up and am wondering how many hp yall think i will get from it. i was also wondering what size tb should i use i have acces to a 68mm for dirt cheap -=150=-!! well thx lots and right now i am putting 160hp and 114trq to the ground. my engine mods are
98 b18c1 p72 ecu
underdrive pullies
homemade ram air intake
full exhaust <no header yet>

i am currently runing 14.89 on good old steelies.

update- i have just put a OFFICIAL mugen chip in my old p28 hopefully this will help some.

I'm gonna take a guess at +4 in one part of the rpm range and -4 where the +4 isn't. But make sure you always quote the +4 range.

I really think you could benefit from a header if you already have full exhaust. Your header is a restriction to the rest of the exhaust work you have done. good luck

I bet you wont make that much more power at all, SIRII intake manifold? off what a B16a? on a GSR? you do know that those intake manifolds are not swappable right?

I'd throw a header on to see a real gain.. or ----, your here at HMT, its time to step up and boost that GSR, thats what they were made for 300whp feels good, try your B18c with about 10psi and some good EM, you will be set
