hey guy can some tell me if there any diffrence between a 91 head and intake vers a 92 integra head and intake
also a 95 ls intake
thanks

there is not much difference between the pr4 head and the later p75 both flow like s=;t but if you have a choice get the p75 head it is slightly better

X2 on the B1 mani. the B1 makes alil more power basically cuz the head flows alil better so yeah get that one

Yeah the P75 head is better, cams are a bit better also. The PR8 I think it is from the B20Z is the best and hard to find, much better flow, Vtec sized intake valves, much better intake cam. The B18B1 intake is also the better flowing as is the B1 exhaust manifold.

I dont know about the heads but I beleave in 92 they redid the intake to flow better...

90-91 B18A1 132hp 121lb-ft
92-93 B18A1 140hp 130lb-ft
94-01 B18B1 142hp 130lb-ft
96-98 B20B 126hp 133lb-ft
99-01 B20B/Z 147hp 133lb-ft

The best stock intake mani is the OBD2 P75 intake mani, all pre 96 manis suck.
