Looking to upgrade your s400 turbo to get the most performance out of it before needing a T6 setup? Look no further. The 93mm turbine wheel is the largest size turbine wheel that you can comfortably fit inside a T4 housing, and it will offer similar performance to the larger 96mm turbine wheel that usually needs a T6 housing.
Sent with a T4 1.00 exhaust housing for maximum efficiency as far as drivability and longevity of the turbo in mind.
Please re-use your turbine seal, a new seal NOT included.
