I just got a b18b from my cousin. now heres the problem im trying to put into my 1994 civic which still has the d15b7 in it. the b18 is the engine it self with the intake and exhaust manifold also brings the whole wiring. now what else would i need. obviously i would need the clutch, flywheel, tranny. but i heard arond that i couldnt use any thing else so what would i need to complete the swap and what ecu should i use can the p75 be used ?? thanks.
