So, someone on here was trusting enough to let me do work for them, i know right ? ( one day you guys will get my humor ) Anyway, this wasn't a major upgrade just the comp wheel as turbine upgrade means using Chang made product and i refuse to touch them. Comp wheel is MFS ( shinny ) 50mm inducer with increase radius and tip height, Issues are they are so new very few parts can be obtained so i had to make the turbine rings as this needed oversizing as it had been leaking oil badl
