For street driven cars, it’s hard to beat the responsive nature of the stock sequential turbo system. The compromise with the stock turbos is ultimately air flow. We have been able to develop impressive street performance with a properly tuned, twin turbo RX7. We’ve even seen 11 second times at the track, but if more performance is your goal, a turbo upgrade kit is in your future.

 

Here by overwhelmingly popular demand, the famous Efini twin turbos ARE BACK! As many are aware, Mazda continued producing the RX-7 and developing the platform until 2002. One of the best updates was the power change for the 1999-2002 models. The key to this power change was the improvements to the turbochargers. The compressors received special abradable housings to improve impeller blade clearances, turbine housings are roomier and connections were improved for better reliability. The sum total of all these changes were a faster responding turbo, better efficiency and higher boost capability. In other words, more power! For many years, only a select few could find these turbos. The cars were produced in such limited numbers, the turbos seemed more rare than finding a unicorn...until now. We have been stocking these turbos and have made them available at a reasonable price. These turbos are brand new. There are no used or rebuilt parts whatsoever. Also included are two new actuators for the wastegate and pre-control. Can be used in either the preferred sequential setup or in a racing non-sequential format. These turbos will bolt directly to any 1993-1995 exhaust manifold and any quality downpipe. We’ve seen close to 400HP at the wheels, but see 330 - 360 frequently. Whether you’re replacing your turbos due to old age or feel the “need for speed, there is no better value than the Efini twins
