This is a C30-74 Rotrax System from Kraftworks set up for a 90-97 Miata with a 1.8L
System can be adapted to a 1.6L. And Rotrex head unit can be used on other vehicles.

This is a Rotrex C30-74 head unit with about 1000 miles on it. Ran great and made 230whp on a 1997 1.8L at 12PSI. Also has included in this kit is a Precision Turbo GIANT intercooler and all the custom made aluminum piping, couplers and hardware to install it. Includes a 80mm Pulley that made 12psi at stock redline. Also has a GM temp sensor mounted in pipe. Included with it is the oil cooler system and oil. Only thing needed for this is a new air filter.


The C30-74 blower is actually rated at something like 300hp from the manufacturer so its definitely got some headroom. Unlike a roots or a positive displacement blower, this thing wants to spin, and it wants to spin MOAR. Also unlike a roots or PD blower, it's not much for low end torque so it is kinder on stock internal motors.

Includes Oil, belt, all hardware and V-Band TiaL BOV.

With injectors and some type of engine management you will have a very solid performance machine.

Got it in a trade deal and I'm going turbo. I'm friends with the original owner. He bought a C5 Corvette for a track car instead of the SC Miata.
