The ultimate in modern turbo technology for your RX7.  Weather you are upgrading from stock twin turbos for more power or just the reliability and simplicity that comes with a single turbo set up. This is the kit for you and here is why.

The SAS Autoworks S300sxe  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 thick billet head flange, a billet  T4 twin scroll threaded turbo collector, 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 S300SX-E 61mm 83/80 or 76/80  with a choice of 0.91 1.00 and 1.10 AR twin scroll T4 turbine housing. This turbo will see you comfortably anywhere from 300-500 rwhp on a 13B, these turbos are the absolute best answer to affordable boost and still offer great performance. ( we also offer a S363 and S366 kit now too)

  • SX-E Highlights:
    – good responsiveness thanks to the latest compressor wheel geometry (EFR technology)
    – High flow / anti surge intake (EFR technology)
    – Robust, repairable plain bearing
    – Preparation for speed sensor
    – Preparation for pressure connection

THE DOWNPIPE

The SAS Autoworks down-pipe is made from 1.6mm thick 304 Stainless steel again T.I.G welded and back purged for superior reliability and performance.  These come with Two 02 sensor  bungs, one at the top in the original position for tuning, and another at 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. There are 3 options with your downpipe.  Our OEM 2 bolt hole flange options also include a  brace which is located in the stock position.

  • 4″ bore  V band fitment
  • 3.5″ bore OEM 2 bolt flange fitment
  • 3.5″ with 3.5″ V band fitment (mates to SAS 3.5″exhaust)

THE WASTE GATES

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.

 

DUMP TUBES/ RETURNED WASTEGATES

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. I also offer this with both wastegates plumbed back into the downpipe for Street/ track friendly cars. (we recommend a 3.5″ downpipe with this option).

 

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.

  •  SAS Autoworks T4 twin scroll manifold
