i own an 88TII with the following mods:
-intake
-downpipe, custom mid-pipe, cat-back exhaust

i'm currently running a factory fuel system without an FCD. my boost gauge reads 12psi when the engine bogs at around 4500rpm. i've considered getting a shop to tune my ECU w/ GReddy E-Manage and replacing my fuel pump and secondary injectors with 720cc units. i was curious if they drop right in or if they require modifications to fit. i'd also like to know my next logical upgrade...is it an intercooler?

any input on this matter would be much appreciated. thanks.

i'm using 1600 in my secondary, all i did was add about 2 or 3 rubber o ring at the bottom of the injector and bolt them down. didn't have any leaks and they work fine. if money is not an issue i would recommend getting rid of that fcd and go stand alone engine management...find a good tuner shop....but if not intercooler would be the next upgrade. also you need a/f ratio gauge or an exhaust temp. gauge....make sure you are able to monitor the engine....or check with the shop that's gonna tune your car, see what they have to say then get someone else's opinion.
