G35 supercharged
I got a stillen supercharger stage 2 on my 04 g35 coupe running 5-6 psi and wanted to know what size of pulley and fuel injectors you guys would recommend to boost it up to between 11-20 psi. It is a stock g35 just with a supercharger and intake.

Can you get 20 psi out of their roots blower?

Maxmiss - heres the shake...and please do some further research on what other people have done with both supercharger and turbos to get the results you are looking for.
the VQDE will take about 400 to 450whp semi-reliably. So unless you want to build the block up you are capped at 450whp before the engine internals crap out.
I don't know what the OEM ECU in its natural / unmolested form can self-tune to...I want to say +/-300whp...
so you can't just drop in new injectors, bolt on a new pulley and expect large numbers...
you can get up to the aforementioned 450whp on 10-12psi of boost pressure (or whatever airflow that equates to). But at that boost pressure you need an alternate tuning solution - most likely the Uprev setup.
$500 for ~600cc injectors
$200 for the smallest pulley
$1000 uprev license, tune & uprev MAF
So you're looking at $1700 to get up to 450whp - assuming your blower can crank out that much airflow.

ah come on, you know the answer. 
MaxMiss...the previous owner sold you up the river. That stillen kit is undersized for the 3.5L VQ and will not make good power at any PSI. Stage 4 may crack 350whp but that requires a ton of work.
Just be happy with your noisemaker and slight bump in power...you are chasing a rabbit if you plan to go any further.

oh it is enjoyable having it, not gonna lie. one thing i didn't look into before i bought it was the cost of things on it. oil changes are about $100, full set of tires $2200, gets crap gas mileage (because of right foot), small things i didn't think about when i got it.
i love the car, but will love it more next month when it gets heads and headers!

Okay what would you guys suggest to get good power gains? but still be a daily driver. Would you recommend turbo? I have thought of selling the supercharger and with that money get a turbo kit, but i am unsure. Anything you guys would recommend i am open to it.
