T ll w/ all bolt on's; what size injectors???
I have a Turbo ll motor, that's almost done being rebuilt. Here is the mods I'll be running;
89-91 Street port motor, 91 stock turbo (new), racing beat 3" downpipe, 3" exhaust all the way back, front mount spearco intercooler (33"x8"x3.5" core), cone K&N filter, Blitz blow-off valve, underdrive pulleys, lightweight flywheel, HKS FCD, Jet re-mapped ecu, walbro 255 fuel pump, greddy pro-fec B boost controller.
Okay, I looked hard for the answer to this, but cant really find anyone running a stock turbo. WHAT size injectors would be good for this setup? I have looked at many injector calulators, and its a little confusing to me, but it looks like they all say in the 720-750cc range @ 50psi, but 550cc @ 95 psi, is that the right way to do it? It says the stock ecu is running a 65% duty cycle, is that right? . I want to run as much boost without getting out of the stock turbo eff. and have too much hot air. Can I keep the stock injectors with a higher fuel psi? Do I need a boost variable fuel pressure regulator? Would the GSL-SE injectors with resistors provide enough fuel? I'm confused more now than I used to be, as I thought a all-stock second gen would take a full exhaust with defenser, and be fine. PLEASE HELP!!

Before any one else tells me I'm off my rocker, can I even run a stock turbo with those mods? Blue Tll stated that the boost creep would be insane, and destroy the motor. If you guys have any info, I dont mind being told I'm going to f**ck something up, I want to know before I do!!! thanks

GSL-SE or 720s in the secondaries should be sufficient.
edit-
You have a s5 turbo, creep should be minimal. However, once you throw it all together and if you are creeping port the wastegate holes bigger. Kind of a trial and error thing. Of course you could always port it now and avoid any possible complications down the road.

it probably wouldn't creep past 12psi or so. which would be fine with some bigger secondarys. like 720.
if the turbo is still off. port the wastegate
