Critique my setup please.
A larger A/R turbine housing is just a crutch. You motor needs a large turbine wheel!
F.I. has the S400SX4-75 for $650, that is what you need.
I bought my turbo from CRT turbo I can vouch for the customer service at that place. FI is good as well never heard a complaint. Both have the basic S475 listed at the same price. Good luck.
