11364, 16G with stock Injectors and Fuel pump??? Posted by Hult250R, Apr-11-04 06:46 AM
For those of you that didnt read my other post. Im getting a "small" 16G not the Big or Super. (itll be here in 2 days according to UPS)
Would it be safe to run it on stock injectors and fuel pump until I can rob a bank and get an AFC, fuel pump, FMIC and injectors? (Fuel pump will come in the next month or so) Ive got an EGT, and my Apexi TT reads 02 voltage so I can kinda keep an eye on things. What boost levels would be ok for the stock setup? Go easy on me guys... No flames lol (If ur nice Ill hook ya up when I rob the bank)

one thing to take into consideration is what octane of fuel your running. if your using 93-94 then you sould be able to get away with a higher boost level and by high i mean like 8-9psi. but lower octane like 91 will be even less. but an upgraded fuel pump alone should let you boost to around 15-18psi pretty safe. just as long as you keep an eye on the EGT's you sould be fine. correct me if i'm wrong on any of these guys but that's what i've always been told and read.

I always run 93 octane so thats no prob. So with just a fuel pump and stock injectors i should be good to around 15psi? Anyone wanna comment to that??

I wouldn't go past 12 psi with stock injectors and no front mount...also depends on which FP.. 255 non high pressure i'm assuming..SO if 12 is your max, i'd keep it at 8-10 psi if possible (may not be with the 16g wastegate)
its better to be "safe" for 2 months then spend your intercooler money on an engine rebuild...

another thing, will the 255 non non-high pressure over run the stock FPR? Ive got a starion FMIC sitting here, is it much better than the stock SMIC or should i go with a different FMIC?
