4th of July sale includes one free inconel turbine housing shield upgrade( $665 value) with purchase of any of the following full EWG turbo kits; S200SXE, S300SXE, EFR 8474, or EFR 9180. All of these sizes are in stock, the rest are all on back order.
Every piece of this kit is 100% built in the USA and is constructed with the highest quality materials & components. To ensure proper fitment, every kit is mocked up on an actual RX-7 engine and chassis before delivery.
At the heart of the system is a your choice of an EFR 7670, 8374, 9174 or 9180 T4 Free Float Turbocharger. The 7670
will deliver the fastest boost response, and lowest boost threshold, and is perfect for a sub 400rwhp street, or AutoX car. The 8374
will deliver a very wide power-band that will work well for road-course driven cars, or higher powered street cars(450-540rwhp selection). The 9180
is geared more for drag race orientated cars looking for the 600+rwhp power levels.
The main difference between the IWG & EWG Rx7 EFR turbo systems is the EWG(External Wastegate) will produce more top end power, while the IWG(Internal Wastegate) system will produce better response. The EWG system will also hold the lowest boost pressure possible as it uses two 40mm waste-gates vs a single 42mm on the IWG. Both kits come standard with investment cast 347SS turbo manifolds.
This turbo system does require supporting modifications
such as an aftermarket ECU
, intercooler, clutch, fuel
, & ignition upgrades to reach it's full potential.
Turblown Engineeing offers a Lifetime warranty for original purchaser of the turbo manifold and downpipe, and the turbo also includes BorgWarner's One Year limited warranty.
This turbo system fits both left and right hand drive Rx-7s.
All units allow fitment of A/C hardlines, and most V-mount intercooler kits.
FC downpipes are left with a vband, and you will have to mate to your existing midpipe. If higher power levels, and ultimate boost response are desired choose the 3.5" Vband downpipe termination- for use with a custom 3.5" exhaust.
