so you're running the $6,000 kit? if so i can't wait to see your numbers to help me justify the cost

well, the difference between stage 1 and 2 is 7 psi actuator, exhaust, tune MAP sensor.

I have all components mentioned above for stage 2 but added supporting modes to go 7+ psi.


Video added to post 96 and first page.

kinda sux if you already have a front and overpipe since it includes those, but not a BOV, tuning components other then jus the tune file

The vaseline jar cracks me up btw...

I already had OP/DP, you can get stage 2 components minus exhaust

love the sound!

you had battery disconnected when FP was going in, you check ALL your fuses? checked links under black box in hood?

Yes, battery disconnected. I hear the pump priming when I set ignition to ON. Haven't checked fuses, but again can clearly hear the pump priming.

(Thanks for the tips, really appreciated and all good points to check)

When can we expect some more video, dyno etc. I'm curious how the stage 2 numbers will come out with that interesting intake setup and the full exhaust.

The BOV and turbo seem a bit more audible with the unrestricted airbox too sounds great!

I hope soon, but can't promise a date. I'm still working a stupidly crazy amount of hours.

David,

7psi wastegate spring is a good thing! You have 93 octane gas in Florida right? Maybe even 94 in some places? I would LOVE to see the turbocharger operating in its highest efficiency island, but that would require a LOT of ancillary support components. I know you've said that you're going beyond 7psi, but pray-tell, would you come close to the efficiency pressure ratio of the turbocharger?

If anyone is curious, the highest efficiency island on this turbo should be around 13psi or thereabouts. :-)

My goal is not quite that high, but will definitely be 8+ . I get 93 octane here in FL, honestly don't know exactly how good it is but it seems pretty good.

[buditjoenawan]

Hmm, 8+ is rather vague. Would you venture beyond stock clutch/injectors/pump?

I'm rather curious as to the chassis' ability to handle the increased power. In my FD, 260whp on street tires (265s) on the street was a handful when not going straight. And I think the FD and the FRS/BRZ are pretty similar in weight.
