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.
