Product Details

K Spec Subaru Turbocharger

This K Spec Hybrid, (formally known as the MHI 18K Spec) turbo comes with our popular 54.8mm billet compressor wheel. Same compressor wheel that is installed in our R Spec turbo but with a smaller turbine wheel to favor better spool times. If you like down low torque as much as horse power for your city driving or Auto X events, we recommend this turbo.

Available with our upgraded journal bearing or a ball bearing system.

We compared our K Spec wheels with the popular MHI 18K assembly and found a huge difference in weight and aero technology. Pictures display how much lighter our turbine wheel is and how much more blade surface area our compressor wheel has. Overall you will get a better performing turbo from us. 

Available with 7cm or 8cm turbine housings. ( please note which housing you want during checkout)

SPECIAL We are  currently offering a 40 day exchange program on the turbine housings, if you wish to try a different sized housing we are offering an exchange program. You have only to pay the shipping charges.

Your new power house K Spec turbo will come with an upgraded 14psi  waste gate actuator. If you don't plan on boosting more then 18psi then let us know and we can weld the flapper shut as you will need to go with an external waste gate.

To help you with the install, new exhaust gaskets, coolant and oil gaskets will be included.

High speed VSR balanced in house to 100 000 rpm +
