Garrett GT3582R (aka GT35R, aka GT35/40R) Turbocharger
No matter how extreme I make all my engine modifications, the turbocharger is the crowning touch. It is the turbo that will ultimately make this project all the worth wild! Over the years I have searched, look and gone back and forth between different tubo options and trims. In the end, after lots of research, I was able to make my final choice...and I couldn't be more pleased.
I wanted a high horsepower engine, so the GT35R with an .82 A/R exhaust side was the way to go. It may be a bit laggy on the low end, but top end power will be insane. This turbo will max out around 36 PSI and has the flow capacity of 600HP. The compressor housing has a custom anti-surge port ring which eliminates compressor surging. This feature is a standard on the GT35R when you order it from Forced Performance. The anti-surge feature comes in handy when boost conditions put my motor left of the surge limit line on the compressor map. I had the compressor housing polished. The turbine housing was upgraded to a Tial stainless steel V-band housing. This housing is stronger, lighter, smaller, flows better, and uses v-bands for the inlets and outlets. This makes install and removal easier and gives piece of mind about blowing gaskets. The Tial housing was thermo-coated. A Garrett turbine stainless steel heat shield was used to further help keep engine bay temps down and polished for a cleaner look.

Tial External Wastegate
For my external wastegate, I decided to use a Tial 44mm. Tial wastegates are known to be extremely reliable. External wastegates allow to be installed in ideal locations to allow for better venting and boost control.
