Yeah that is what I thought too, I dont understand the physics and what not behind the sizing, but why would lexus use a turbo with a smaller exducer? quicker spool? I looked at the garret turbo page and every one I saw had a larger exducer. Precision turbo has a turbo with a 48 inducer and a 57 exducer that they rate at 385hp http://www.precisionturbo.net/turboc...-4831B-MFS/552 but I dont know what else goes into how much the turbo can actually flow.

I'm pretty impressed with the inducer size and if adding more turbine blades (surface area) it'll be even more responsive. This turbo should be impressive with internal upgrades alone. All while appearing completely stock

I have seen in videos, even with the tune the boost drops off at the top. The larger exducer might help hold boost all the way to redline and that alone would increase the max hp a bunch.

The 8ARFTS use twin scroll turbine housing and different size of inlet.

I wouldn't mind a tune + fairly conservative turbo upgrade to make a safe 350-375 whp. Is our cooling system up to it Tony? Theoretically it should be.

I think 350whp is wishful thinking, but I wouldn't mind it. I do run 265s in the rear after all.

I want to know- is our diff common to the 250 or the 350? Or its own thing? I'm thinking about putting an ISF torsen LSD in there...

Anything happen with this turbo upgrade?
