difference between 90/91 and 92/93 HP??

90/91 had 130 HP, 92/93 had 140. My question is how was this accomplished?? Was it different cams or something??

Is there any thing I can change/replace to get this 10 HP bump??thanks...
I bought a 91 Integra LS for parts for my civic, but after a few hours with the teg, and the civic got the "for sale" sign hangin from it !!!!!!!!!!! Ha ha ha

My uncle works at Acura and he told me that after 91 they changed the intake and it boosted it up 10 hp to 140.

I believe with the Accords of the same years, they changed the exhaust manifold/header to add the ~10hp that would accomidate the extra weight that the newer luxury models would have...I assume this is along the same lines.

anyone know what manifold is on the 93 - 94???
or how i can tell the diference when im in the junkyard???

an dam, 10 hp, just from a different intake manifold!!

no body knows???????

You mean on a 92-93. Hmm you could look at the vin or the injectors! The harness should be OBD1. All 92-93s were obd1 and 90-91 were obd0! Im sure the 10 extra hp wasnt just from the manifold. the timing ans onboard diagnostics and sensors were different
