Garage Whifbitz Toyota GR Supra A90 – BMW Z4 G29 Top Mount Turbo Kit

Description

Garage Whifbitz top mount turbo kit for the 2020+ Toyota GR Supra A90 and BMW Z4 G29 2 port B58 engine.

If you want to take your Toyota GR Supra or BMW Z4 G29 to the next level then this is what you need, our turbo kit is capable of 1000+bhp depending on which turbo is used and what supporting mods are fitted.

Our turbo kit uses only the finest quality parts including a Whifbitz 2 port tubular manifold, 2x Turbosmart Compgate 40mm wastegates and a K&N air filter.

Our turbo kit uses the Precision range of turbos, either the 6466 Gen 2 or 6870 Gen 2. The 6466 is rated to 900bhp and the 6870 is rated to a 1000bhp.

The dyno graph below is using the 6466 Gen 2 T4 divided 1.00 A/R turbo at 1.8 bar boost on 99 ron pump fuel making a nice useable 525whp which is an estimated 622bhp. This was fitted to a 2020 Toyota GR Supra which was already running one of our Whifbitz titanium exhausts, Wagner Tuning chargecooler and then tuned on Ecutek with a Motiv Reflex controlling the boost. More power is available with the of ethanol fuel, 750bhp is easily achievable without touching the standard factory engine and gearbox. After that a forged engine and uprated gearbox is advisable where you can then run 900+bhp if you desire.

The 6870 turbo will make about an extra 100bhp than the 6466 with slightly more turbo lag but for those wishing to push things to 1000bhp this is the option for you. We can also supply our turbo kit with the latest Precision next gen turbos which are producing even more power at an extra cost.

Our turbo kit comes with the following parts:

• Precision 6466 Gen 2 or 6870 Gen 2 turbocharger
• Garage Whifbitz tubular stainless steel manifold
• 2x Turbosmart Gen V 40mm external wastegates
• 3.5″ stainless steel downpipe with external wastegate plumbed back
• K&N filter
• Chargepipe to connect the turbo to the throttle body with a Turbosmart Raceport BOV flange fitted
• Braided Oil and water lines with Funk Motorsport heat sleeving

Optional extras include:

• Highly recommended is Thermomet heat management for the manifold, downpipe, wastegates and turbine housing, this is really important as the downpipe is very close to the engine cover and battery wiring. Pictures show the Thermomet heat shielding.
• We also offer Funk Motorsport turbo and wastegate blankets as a cheaper alternative to the above

Extra parts required:

• Turbosmart Raceport Blow off valve
• Motiv Reflex to control the boost
• 3 port boost solenoid

All of these parts can be supplied and fitted here at Garage Whifbitz or supply only if you want to fit them yourselves.
