Ok . I am a relatively new owner of a 86 gn. Quick breakdown, the car has what i was told is a pt54 or ta54 from precision, converter with a 3500 stall with od. rebuilt tranny by Ivan in miami Tranny tech, front mount (big one that is not sold anymore??) with 3 inch piping, dual fan setup running high only(they both turn on like around 170 or so, then shut off after temps lower, on with ac), it has what i was told to be 42 lb green injectors, a red chip that i was told was for pump gas, 3 inch down pipe, aftermarket fuel regulator, a stainless dual exhaust kit.Stock block and stock heads.
I have a small miss at idle that is recent, with about 17 inches of vaccuum, and im wasting a whole lot of gas, and the car pops after like 15 psi of boost and breaks up. I have what I think is too much fuel pressuer under boost. I have 37 psi at idle, and at 14 psi i have about 64 psi of fuel pressure, If I increase the boost to about 16 psi i get even more fuel pressure and the problem gets worse. yesterday i checked the fuel psi , bc when i turn off the car, initially it went up, upto 42 , then in a matter of 10-20 minutes it dropped to 20 psi,??? I am thinkig I may have several issues at hand.
I want to replace the plugs, but i dont know which ones would be the best to use for my set up????
what on these cars may cause the fuel pressure to increase so much under boost? 70 psi at 17-18 psi of boost??
is a 3500 stall too much for my daily driven car with this turbo? im not sure what version it is, but its a precision and its a 54 trim, could be pte ,pt, ta?? how can i tell by looking at it. The inlet is a 3 inch , not 4, and uses a rubber coupling on the intake side, not a bolt on adapter.
you guys know anyone in fl that will tune tha car for me correctly, bc i got some service done at harpers racing, but he doesnt drive the cars, so he cant tell me wats wrong. i guess hes scared of breaking something ??? first time i hear that, he just tells me to put up the boost and it should clean up, but then i also get too much fuel psi? unsure what to do at this point.
