Not much else will fit in the tiny engine bay of the mkiii and provide the flow needed.
A few local buddys have never had an issues with the hydrofans.
I hear what you're saying, but its not 100% all the time. Obviously the turbine needs a certain amount of flow through it to actually spool it and the increased velocity of the airflow has a slight effect on the spool, and maybe with your .58 you're simply not getting enough flow through it and...
Too small for your setup? what are the goals with the car (what do you want to do with it, rather then 500whp and quick response)?
I skimmed over that thread and I'm quiet surprised by the response of the 35r on the IS, I didn't think itd come on that fast, wow. But My point still holds true...
GT37R is a 4088r compressor with a 35r turbine IIRC.
The NA VVTi rods are weak and small. Do a search on SF or club lexus about it. They're much smaller then the old non-vvti Ge rods. The GTE vvti still has big strong rods in it like the previous GE and GTE.
If 4k is too late you'll have...
vvti ge bottom end is garbage, and go with a GT37R turbo or PT 6262.
I assume the proefi 128 will control the vvti without issues?
Shimless buckets are a waste of money at this stage.
If it were my car, I'd go gt4294 with 9.5 compression.. vvti + high compressor the turbo will probably be...
