The SAS Autoworks S200sxe Airwerks turbo kit is the ultimate in Bolt on affordable power and reliability for your RX7. This kit was designed not just to fit and look good but to work and work hard!.
THE MANIFOLD
With the 13B Rotary running significantly hotter than a piston engine, getting that heat out is important. Runner length plays a key part in this, the more surface area you have to disperse heat the better just like an inter-cooler or radiator. Longer runners also help to develop more low down torque for off boost response. This aids in trying to maintain as much drive-ability as possible without compromising horse power up top. Couple this with the already exceptional efficiency of the BorgWarner range and you have a recipe for exceptional throttle response and an amazing power band all the way through the RPM range. The manifold is made from 304 sch40 stainless steel which is T.I.G welded and back purged for maximum strength and flow. Featuring a 14mm CNC machined thick head flange, a 12mm thick Billet T4 twin scroll threaded turbo flange, and two 40mm wastegate take offs to suit the latest Turbosmart gen V 40mm wastegates. For the ultimate in boost control.
THE TURBO
A BorgWarner Airwerks S200SX-E 57mm. This is the entry level size turbo to going to a single and will suit a stock or street ported engine for anywhere in the range of 400-450 flywheel BHP. The inducer and exducer are the same size as the EFR 7670 however the S257sxe actually has a larger choice in hot side A.R choice.

THE DOWNPIPE

These come with a 02 sensor bung on the bottom for a wide-band sensor or whatever you so desire to fit in there. All Our downpipes feature a triple skin interlocking stainless steel flexi joint to aid in movement expansion and reduce NVH. We only offer a 3″ downpipe with this kit as 3.5 or larger is not necessary for this sized turbo all downpipes are brace which is located in the stock position.

THE WASTEGATES
Turbo smart are well established when it comes to boost control so it just makes sense to use their latest Wastegate in our kit. The new Gen-V 40mm comp gates are a direct upgrade to the V4 and still interchangeable. These come with a variety of springs up to 14psi and come as default in black if you would like another colour please contact us.
THE DUMP TUBES/PlUMB BACKED
The twin dump tubes are again made from 304 stainless steel and back purged for superior strength and reliability. These fit around the sub-frame and point downward away from anything that can ignite or be damaged by the heat when they open. We also offer these Plumbed back for less noise and more streetability.
THE OIL LINES
The oil line kit includes a AN4 braided stainless steel oil feed line. Adaptor to go into the block and onto the AN4 oil feed, and a AN10 Oil return line kit with fire sleeve.
HEATER MATRIX RELOCATION PIPE
With this kit the stock heater matrix hose can be in the way and often too close to the turbo. So we have included a aluminium hard pipe to re route it on the cold side of the engine out of harms way. This comes with all necessary silicone hoses and clamps and bolts to the chassis as pictured in a oem bolt hole.
