Hey guys, does anyone know the exact specs of the turbos that come in the JWT twin turbo kit, specifically for the 530bb kit. I want to know if anyone knows A/R or trim, the model of the turbo, etc. I know they are t28, but is it the gt28 or the g25? Thanks guys, i was just curious because we are comparing these with the turbos on a stock 335i.

 

I believe they are a custom garret series based on a GT25

 

i know they are custom. but by any chance does anyone know or done any measurements on theres to find the a/r of hot and cold side.
