If you really want a sleeper, take that scoop off. Otherwise there's no way in hell you're fooling anyone into thinking it's an RS.

So unless those JDM Forester heads are built I'm having a hard time imaging all that power.

Just to confirm your running 93 oct hitting peak boost at 4400RPMs @ 25.5psi tapering to 23.5ps i@ 6900rpm's? On an Internally gated setup, and stock MAP Sensor?

Oh god and SPT exhaust That SPT chokes turbos like I choke my chicken. That is a lot of power to the ground for that setup.

Ive seen guys running GT52/Hydra/Hydrmist and not come close to that on pump.

I'd get rid of that spt and throw on a ewg kit then you may hold more power up top

4st the stock MAP sensor will maxed out about 25 psi so that boost level can be reached but not so sure you want to do that on 93 octane. The peak numbers are nice but they drop off a lot. My set up with the 20G on 93 octane is holding up better up top which tells me something is holding you back up top (cams, SPT exhaust...) or the tune can be improved. This is the link to my thread just in case you want to compare.

http://forums.nasioc.com/forums/show...t=junior+tuned

My peak numbers are not as high but the drop off is not as bad. I don't want to hijack the thread but i've done some improvements on the road using open ecu and airboys spreadsheet is recording up to like 375whp which is very nice for pump on a simple setup. Toback up the improvements right after i tuned the car i used airboys spreadheet and it was dead on with the dyno numbers so is a fair comparisson. I can post those graphs later on today if someone wants to see the improvements made.

LMAO I'm finding that even harder to believe then.

Stock MAP can read accurately up to ~24psi but he is hitting 25.5psi and now Im being told this is on 92 oct? That's living on the serious edge of a time bomb.

These are most definitely SAE corrected numbers.

25psi and 11.5-11.7:1 on pump gas?? Do you have an EGT gauge?

I understand why you're running 25.5psi on pump on a built block, but you're happy with such a late spooling GT52? That torque drops off worse than a VF39 and your HP drops off pretty bad as well. I see GT35R spool with VF39 power curve...

92 is the highest pump fuel in WA.

Nice numbers.. but to be honest, something is wrong with the graph..
Your bottom end is hurting bad.. anyway your tuner can tune that out..

Also your taking a HUGE risk with 25psi and 92 octane...

I believe there is some tweaking to do with the GAIN on the turbosmart e-boost.

Yes it was tuned with 76 92 octane.

I really love the feel of the GT52 it dosnt feel laggy like the graph shows..

There is more power to be made on it specially since i still have the TGV's....

Thanks for all your feedback.

My plan here real soon is to go external wastegate and intake manifold and TGV deletes.


I have the SPT exahust because i dont want a modfied exhaust ticket.. If i get stopped i have the SPT advertisement and i can show the cop it is a factory option.

But i am thinking of running the electric cut out valve again...
