s14 sr20det with t3/t4 stock ecu 370cc boosting 7 psi is that ok?

[david200095367]

I have a s14 sr20det i upgraded to a t3 t04e 57 trim. Im running 370cc and z32 maf with stock tune. Would it be ok to boost 7-8 psi on this with stock 370cc and stock ecu?

[S14toRPS13]

If your computer's tuned for the Z32 MAF and T3 turbo to run with the 370cc injectors, then yes it's safe. If it's not tuned for it then no I wouldn't run the T3 turbo with 370cc injectors.

[david200095367]

its not tuned for the t3/t4. so running 7-8 psi on the t3/t4 will run lean?

[david200095367]

anyone else?

[srdub-t]

how are you running a z32 maf on stock tune? do you have an safc? if so get a wide band and tweak a little bit and ull be fine. Eather that or get an enthalpy tune for 500 bucks. But if you were gonna get an enthalpy tune i would get some bigger injectors so you could boost more.

[david200095367]

yea i have a apexi safc. I do have an enthalpy tune but im looking for a better deal on some nismo 740cc injectors. Which wideband do you guys recommend?

[Emperor_Tha]

I got an autometer wide band for 300 it ranges from 10to16.0 afr

[david200095367]

im loooking for something in the $200 range. Im also not a big fan of autometer.

[srdub-t]

i have aem uego but the innovate is really good too.

[inkslingers13]

i also have a uego. good stuff

[david200095367]

thanks guys! i went ahead and bought a lc-1 wideband. I got a very good deal on it and it also datalogs.

Stop while you're ahead.

Get the proper fuel setup first. That means, biger injectors, ECU, pump, etc etc

Leave the stock turbo on there for now, and just enjoy it. Put the bigger one one once the rest of the car is ready to go.

[david200095367]

I already have a fuel pump but Im waiting for my 740cc injectors. I was just curious if the way I had it would be fine temporarly.

[codyace]

Don't risk your engine.

[david200095367]

i got my wideband so i will let everyone know how it turns out.

[codyace]

why not get your fuel system and all setup first?

a wideband is a quarter of the solution.

[david200095367]

ok Cody i will throw in my 550cc and tune. And when i get my 740cc then i will throw in the other tune.
