FAQ
Is this a direct bolt-on to my stock VGT system?No. This is a 2nd-gen-style T4 conversion. It replaces the stock VGT and relocates components. Tuning and added parts (oil lines, downpipe, intake, etc.) may be required depending on your configuration.
What turbine A/R should I choose?The .91 A/R on this 64/74 balances spool and top-end for street/tow performance. Tighter (.88) can improve response; larger (1.00) favors top-end on higher-horsepower builds.
Do I need head studs?Head studs are strongly recommended any time boost and cylinder pressures are increased, especially on tuned/towed applications.
Will this lower my EGTs?Compared to a restrictive or failing VGT, properly-sized SX-E setups can reduce EGTs under load when paired with correct fueling and tuning.
