GrimmSpeed Subaru Top Mount Intercooler (02-07 Subaru Impreza WRX, 04-13 STI, 04-07 Forester XT)

GrimmSpeed Subaru Top Mount Intercooler (02-07 Subaru Impreza WRX, 04-13 STI, 04-07 Forester XT)

So, you probably already know that you want an intercooler with maximum cooling and minimum restriction, but when it comes to selecting the right ‘man for the job', we think it's important to understand why. As air is pressurized by your turbo, it heats up, not because of the heat of the turbocharger, but because when they're compressed, the atoms in the air are forced closer together and as a result, move faster and have more energy. That energy manifests itself as heat.…

Grimmspeed Lightweight Crank Pulley (Subaru)

Grimmspeed Lightweight Crank Pulley (Subaru)

For our Lightweight Crank Pulley we pulled out all of the stops. CNC machined from 6061 T6 Aluminum our pulley makes no compromise. It weighs in…

GrimmSpeed Turbo Heat Shield (Subaru) 092002

GrimmSpeed Turbo Heat Shield (Subaru) 092002

We knew when it came time to design this product we didn't want to just create another heat shield to add to the mix, but create another level of product. The basic heat shield would not cut it, we wanted every fitment of turbo, downpipe, and up pipe combination we could work into one design. We measured, cut, bent, welded, riveted, and after many tested prototypes we arrived at a heatshield we are extremely proud of. Other heatshields had problems with cracking, poor fitment…

Grimmspeed Adjustable IWG Mounting Bracket (Subaru)

Grimmspeed Adjustable IWG Mounting Bracket (Subaru)

The internal wastegate(IWG) bracket is used in place of the stock wastegate actuator when moving to an external wastegate setup. In previous years, Subaru owners had to weld the IWG shut on their turbos which diminished resale value, had the chance of cracking, and made it very difficult to revert back to the stock IWG setup. We are bringing you the solution to this problem, the IWG bracket. This is a basic bolt-on which takes 5 minutes to install. No more worrying about the…
