Garage Whifbitz Twin Wastegate Supra Turbo Kit

Garage Whifbitz twin wastegate turbo kit.

This now replaces the old single wastegate version. Mainly because it has proven to work better improving spool up by a significant amount and its only slightly more expensive so there really is no point in manufacturing both kits.

The twin wastegate manifold is now available as a complete bolt on kit, I believe this is the only twin wastegate kit in the world to come as a complete kit.

I’ve personally been testing the manifold out on my own Time Attack car and results were sensational. Compared to an HKS manifold I gained around 800rpm spool up and we’ve fitted the manifolds to a few customer cars now and again the results were stunning. You can read about some of this here.

The kit itself will come with everything you need:

3″ downpipe/midpipe for cars up to around 700bhp.
4″ downpipe and midpipe will also be available for those wanting to push some big power.

Both size options will be available with the option of the wastegates recirculating back into the downpipe for those who want to keep it quiet or open wastegates for those who want terrorise there neighbourhood.

Turbo wise, you can basically chose what you want. From super fast spooling 550bhp turbos to a 1000bhp turbo and anything in between.
“Off the shelf” kits will intially come with the Borg Warner Airwerks turbos, these range from 550bhp up to whatever you want basically. These will probably be replaced with the Borg Warner EFR turbos when they become more readily available. You can also opt for Precision or Garrett turbos if needed to.
