Hi Guys...newbe here whit turbos
I posted a question and no answers so im trying again...her goes
I have a 1987 supra whit a 1jz the engine is stock and purrrrsss like a kitten exept when i open her up from 1st to 5th gear at around 6500 rpm it wont go anymore it kind of chokes and feels like misfire, coils are new,plugs also new. ive checked for vaccum leaks ...couldnt find any.its running whit the twins ct12a ive inspected the ceramic turbines and no damage ..its real clean in there. theres a 3 inch exhaust system all the way to the back, huge intercooler no leaks there eighter.
The motor starts and accelerate perfectly lots of power exept the aprox. 6500 rpm mark, its like the turbos wont open up, im pretty shure its not a firring issue, compression on all cylinders is 158 to 160...
The original motor was a 3 ltrs..im wondering if the fuel pump should have been replaced, there dosent seem to be any tampering in the fuel pump compartment in the hatchback...could this be an issue
can anyone help me please on to what i should be looking for
thanks
