Whifbitz 2JZ Borg Warner EFR Turbo Kits

We are now supplying our popular Supra turbo kits with the Borg Warner EFR range of turbos. We’ve been busy testing the turbos out and they perform very nicely, the EFR 8374 EWG turbo is our favourite if you want a super fast spooling turbo setup. Maxing out at around 620 bhp on pump fuel which would make over 700bhp with E85 fuel.
The EFR’s are also available as internal wastegated too which saves money as you no longer need the external wastegates. The EFR’s also have a blow off valve and boost control solenoid built into them, all helping to keep the costs down on your build.
This version of our turbo kit uses the Borg Warner EFR External Wastagate turbos, this kit is designed for anyone wanting to run from 500 to 800bhp, the turbo options available are:
• EFR7670 external wastegate turbo rated to 600bhp
• EFR8374 external wastegate turbo rated to 700bhp
• EFR9180 external wastegate turbo rated to 800bhp
We have been using the Borg Warner turbos on our kits for years and they have proven to be bomb proof, spool fast, reasonably priced and produce some great power. And unlike some of the other manufacturers out there these are available off the shelf for fast delivery.
We believe this is the only twin wastegate turbo kit available in the world and also one of the best quality most complete kits on the market today. We’ve personally tested our kits on both of our Time Attack cars and results were sensational along with 100% reliability in the harshest of tests, on the race track where they are tested to destruction.
We also dyno tested our manifold design against the HKS manifold and we gained around 800rpm spool up, which is a huge gain that you really feel on the road or track. The kits have been fitted to many customer cars and again the results were stunning. Our kits are used on many cars worldwide proving themselves time and time again, used by ourselves on our Time Attack cars now producing over 1300bhp, Sats Motorsport BDC drift car, Jamie P’s old 1200+bhp car and countless others. We’ve never had a warranty claim, never had a failure, never had a complaint.
As well as the turbo the kit comprises of the following items:
• Garage Whifbitz T4 stainless steel twin wastegate, twin scroll exhaust manifold, made in the UK to our own spec and comes with a 5 year anti crack (subject to usage) warranty from point of sale. Spec as follows: T4 turbo flange, 4mm walled 304 stainless steel construction, billet stainless steel collector, triple pass welded and back purged for seamless internal welds, we believe this is one of the highest quality manifolds available in the world. We’ve never had one crack or replaced under warranty.
• 2x Turbosmart Compgate 40mm external wastegates, external wastegates are routed back into the downpipe for quietness.
