Sr20 Problems Please Help

[91white240sx]

I have a blacktop s13 sr20 motor, the motor ran fine. i decided to do a turbo upgrade last june. i got all my parts brand new: Gt2871R turbo, Stainless steel manifold, z32 Mafs, 850cc power enterprise injectors, enthalpy tuned Ecu. I had everything installed recently and i can't get the car to idle. when i start the car it seems like it wants to start but as soon as i hit the gas it dies, and if i hook the fuel lines up backwards it starts right up, but when i hit the gas it dies also, also it will run until the motor warms up then i dies again. Im thinking i'm dumping too much fuel, the ecu is tuned for the 850cc injectors but the people i bought it from (enjuku) said that they i don't need a aftermarket FPR, and the stock one is good enough. I tried checking the light on the ecu to see if it was giving me a code, but the light is constantly on, and will not flash, they(enjuku) said the since i have the rom tune it will not give me any codes. Thats where i stand on. Not knowing what to do. Please help.. if anyone has any ideas.... let me know either on here or email me at [email protected] Thanks in advanced

im gonna have to go on the injectors. those are WAY too big for that turbo! lol. the .86 will do a lil over 400hp and the .64 will do like 375hp, so why go with 850's?! the rom was done for the z32 right? that can cause it to freak out like that. if youre throwing all this money into your car, spend an extra $125 and get the nismo fpr and a cheap gauge. i heard the stock fpr causes inconsistent fuel after like 550's but im not positive on it.

yes it was tuned for the z32 mafs. the reason i got the 850cc was because i waited 3 months for the 740cc injectors but for some reason everyone was on backorder. so they told me that i can use the 850cc and they would down tune the fuel on the ecu. i will try to get a fpr in the next couple of days and see if that solves the problem... thanks

im running the same turbo on 650's no problem. give me a heads up when you get the fpr, if that doesnt fix the problem, maybe it will tell us whats wrong.
