1990 Mazda Rx-7 6 port Turbo, Haltech 1500

Postby Relisys190 » Thu Jan 27, 2022 7:08 am

Greetings from Sunny Florida USA!

In Jan 2021 My 1990 Non Turbo rotary engine with about 70,000 miles on it was pulled and converted to running a Haltech Elite 1500, BNR stage 3 Compressor with a factory S5 TII Hotside turbine and OEM exhaust manifold. Below is the list of parts added. My good friend and tuner helped with creation of the engine harness and first startup along with Tuning. The car is currently running E-85 very happily making 10 lbs of boost with the 9.7-1 factory NA compression rotors. The entire project took about 6 months from start to finish in my garage. I did not do the harness myself, also had the exhaust downpipe modified to work with my existing RB exhaust setup. Very happy thus far with the ease of use and tuning of the ESP software.

* Two special notes are (Running a 3 Bar Subaru external Map sensor & Running a PWM controller on my fuel pump to keep fuel and pump cool under cruise and light loads *



Enjoy! -Markus
