I'm pretty sure you have a valve body upgrade and it shift pretty hard even when barely on the throttle.

I am doing NA-T just fyi it is faster and cheaper and the stand alone isnt all that bad I used a Pro-EFI and took my tranny out and upgraded the valve body. its not done or on the road but so far im only set back a few g's and pretty much done. just figured id put my two cents in

Good to see another boosted IS300 on the road. Standalone is the only way to go on the NA-T

agreed x100 as i just finished a true na-t build on one which did 415@only 15psi on a old school precision sc61 turbo .. aem was tuned to perfection by alpha and the car behaves like a stock is .. it drives the same everyday and we have full control of vvti .. car could have made closer to 450 but we were concerned about his w55

Did you have a stock bottom end or did you put GTE Internals? I was wondering how many HP can my stock bottom end on a GE motor hold if It was boosed. I know the automatic transmission is safe til about 450 hp.

I am boosting my IS soon and I am going GE-T cuz It's cheaper. But I honestly want to know how safe am If the bottom end is stock.

I Live in Pensacola, FL and theirs barely any IS300's out here, I am a Lexus FanAddict
