SupraStore.com is proud to introduce the industries first Borg Warner EFR based and cost-effective turbo kit for the 1993-2002 Supra Turbo!!! These turbos have a cult following around the world for making amazing power at affordable prices; we bring it to you first!! All of our kits are based around twin scroll designs and are offered externally gated or internally, and all with T4 flanges.
We can go on and on and on about the new BW EFR Series turbochargers, but suffice it to say, there is no more or better technology available in a turbo anywhere in the world!
The SupraStore.com JZ EFR Turbo Kit is fitted with only the best parts, period. All expertly engineered by SupraStore.com
The idea behind this kit is simple. Spool quick, transitional boost response, spool near the stock twins (for 7670), make 600+ RWHP (7670) and run on a minimal fuel system upgrade with a genuine Borg Warner Twin Scroll 7670 .92 AR EFR turbo, mounted on a ProSeries Divided T4 Manifold.
If you order an internally gated EFR turbo, you will receive a ProSeries manifold specifically designed for this turbo, which means we design the collector with no wastegate port whatsoever. Some manufacturers will try to sell you their standard T4 divided manifold and just block off the wastegate tubing downstream. This mistake allows for cross mixing of gasses in the wastegate tube area, and the subsequent turbulence can disrupt flow and increase back pressure (which is a definite no-no) and defeats one of the advantages of the BW EFR internal gate design!
Optionally in the drop down menu, select larger BW EFR turbos to suit your needs. The EFR 8372 Twin Scroll turbo is rated at 800 HP, and the EFR 9180 is the highest performing 68mm turbo on the planet at 1000 HP! Please note the EFR 9180 is only available in an external wastegate.
It uses the best products, make as much usable power as possible and offer the lowest cost possible. A custom world-class turbo kit starting at under $3500 and it uses nothing but TOP QUALITY parts!
Our ProSeries kits are designed for BW EFR turbos, not some retro-fit. We can build a kit around any EFR turbo, but the main possibilities are the EFR 7064 (500 RWHP), which is a good stock twin replacement or an amazing 1JZ kit. We can also step up to the 8374 the EFR 9180.
The kit utilizes the ProSeries in-house developed 304 stainless steel T4 turbo manifold. This is not some cheap China made manifold, but a TIG welded, jig formed ProSeries design. Because the EFR 7670 is dual 42mm internally gated, there is no external wastegate and therefore no external wastegate piping, making fitment amazing. If you want an external gated, we can do the 1.05 A/R external gate design as well. If you select an external gate, you will have a choice of the type of waste gate flange you require (drop down menu). If you desire to purchase a waste gate (Precision Turbo or TiAL) please contact us for details.
This Borg Warner 7670 EFR turbo is designed around the ideas of the largest turbo manufacturer in the world, Borg Warner.
