FAQ
How does the 2nd-gen-style layout help?Center-mounting the turbo on a T4 manifold improves runner distribution and turbine efficiency, typically reducing EGTs vs. the stock location.
Is the HX40 downpipe really included?
Yes-this kit includes a high-flow HX40-style downpipe for a straightforward exhaust connection.
Who should choose the 64/74 with 1.0 A/R?
It's a strong single for street/strip trucks that want more top-end than a 63/68 while keeping reasonable spool with proper fueling and tuning.
What supporting mods are recommended?
Head studs, healthy CP3 and lift pump, appropriate injector size, clean intercooler system, and 4-5" exhaust are common pairings.
