I plan on running a stock det setup with a t-28 and 370cc injectors on the stock ecu. Pairing it with a an safc will it allow me to correct the fuel curve enough in order to make my car run well on 7psi of boost?

Plenty of room at 7psi. I don't have a boost guage yet but I'll tell you my car is f%^&$#@ fast at whatever the actuator spring is rated at 7 or so psi.

Stock ECU
Stock Clutch
Apex SAFC
Apex Turbo Timer
Stock Top Mount Intercooler (Interheater)
Car runs beautiful

I've raced a JWT ECU S3 equiped car and he had nothing for me boosting 8.5psi and FMIC, 16 inch wheel, UR pulleys, JWT PP 2000 Clutch Disc. I have 17-7.5 inch wheel and TMIC and stock cams, SAFC. Go figure.

Yes its already in my car. No its not for another project all thought I have 3 swaps lined up.

1) 91 Sentra SE-R to SR20DET
2) 91 Sentra SE-R to SR20DET
3) 96 200SX SE (GA16DE) to SR20DE

One of Apexi's electornic gadgets. Super Air Fuel Computer. It adjusts the air fuel ratio by manipulating the MAF signal, or there about.

Thanks, still working on it though, trying to update the now dated look.

I don't know. shrug.

I will tell you though, I do get on it allot but I never dump the clutch from a start, I really don't feel the need for that as it already breaks the tires from a rolling start. But I'm not gonna lie it probably does need a stronger pressure plate but so far its been holding up and doing its job. I have a friend with a Nissan Pulsar GTi-R (he just got it 4 days ago, just found out today) and he personaly told me today and along with 3 of my other friends that have driven it, that my car feels stronger than his, he said it pulls harder but he also said his GTi-R needs to be tuned.

Are you sure your only running stock boost? Sounds like your freeboosting. Either that or you didn't get a stock motor.

No i'm not freeboosting, believe me that power is a whole nother story and not to safe. And yes I do have a stock W10 Avenir engine, I should now I took it apart and replaced the rod bearings which didn't need to be replace because they were within spec and I also bleed the HVLA before I put the engine in as every single HVLA was bleed down from sitting so long. It has a stock T25, I know because I took that apart and cleaned it before the swap. Granted I don't have a boost guage installed yeat but I'm using a BB wastegate actuator which normally boost 7 psi or so. My friend has my W10 Avenir wastegate actuator which allows him to boost 8psi.

We swaped wastegate actuators because I faced my turbo up (TMIC) and he faced his turbo down (FMIC) and the actuator worked better accordingly no need to modify a bracket except on his BB a little bit, but when I faced my Aveir turbo up it accepted the BB actuator with no mods direct bolt on.

I could be boosting a little more but im still running a 10.1-11.1 A/F ratio at WOT which is still pretty rich.
