I resently got an adjustable fuel pressure regulator and was wondering if anyone knew a ballpark range of what i should set it at. My mods are world windsor jr. heads with 1.6 roller rockers,a b303 cam, full exhaust, underdrive pullys, cold air intake. The intake however is stock. Thanks

 

I take it your 91 is MAF so why buy a adjustable FPR? cause if you crank it up the puter will just adjust it out for you trying to throw more fuel at it.So keep it stock.... vac line on 32 pull it off place fingure over vac line wait 15 secounds it should be around 40-42.... cheack it every time you stop for a day or 2a lot out there are CRAP i know this first hand.

 

anyone else??

 

40-45ish

 

38-40
