Do I need to upgrade my fuel injectors if I have the basic bolt ons such as:

Bönez Down Pipe
Exhaust
Bönez Hi flow cat
M2 CAI
SR Upgraded Intercooler and piping
Upgraded radiator
Efini Y pipe

What if I get a
Mild street ported 13b (Atkins?) and turbos(Pettit?) running 10-12psi?

Is a fully programable setup like haltech or AEM EMS needed? Or would it be safe to get an supra tt pump and run an FMU with a S-AFC to tune?

(Also I have a J&S safeguard from my turbo prelude project I'll be using as well)

Thanks a lot,
Jeff

as long as you say at 12 or below...you should be alright with the injectors....but I bigger fuel pump+rrfpr and PFC/AEM wont hurt...but I would forget about wasting money on S-afc

Basically, you want bigger injectors when you want to run higher boost levels. You can basically have all the addons you want, but if you only run 10 PSI on boost, then there is no need for larger injectors.

If you plan on running 12-14 PSI of boost, then yes, you need larger/additional injectors. If you do add larger injectors, you should change out the stock fuel pump just for safety sakes.

DOH! Johnny beat me to the post.

Thanks for the info, can I expect to see around 300whp with that setup?

I run 360 plus rwhp on stock injectors and a hipo fuel pump ....

What boost level are you running?

you will probably be just under 300rwhp...I have full 3" exhaust, apexi intake, pettit ecu, with 12 psi and I got 288 rwhp and 251 rwtq
