Surge Tank ✅️

Because this car is a dedicated track car we needed to make sure we dont run into any fuel issues. This is why we have installed a high pressure lift pump and surge tank. A fuel surge tank prevents fuel starvation and pump cavitation during extreme driving conditions like hard cornering, acceleration, or braking.

Clean RTK bubbles 🫧

When it comes to Rotated Turbo Kits we like to use ETS. Flawlessly fitment, vband clamps, EWG. These kits give you everything you want.

Fun 400.

We are almost finished with this project. Customer has a GV WRX sedan. Still running the factory 5speed transmission. So he wanted something that would be fun, reliable and not blow his transmission. He wanted something simple and not brake the bank. We set him up with our poweredbyRPM S2+ short block paired with Blouch 380xt turbo. Cooling the build is a large Grimmspeed TMIC and a Koyo Rad. Fueling with Radium Fuel Rails and a Delicious Tuning flex fuel kit. This build should make 400whp easily with 18-19psi and allow the customer to turn up the power later if he wants.

More Fuel, More Fun!

We are adding a Radium hanger and surge tank to this racecar. The factory fuel pump hanger is not best for a real racecar. In higher g-force turns the fuel can leave the pump causing you to suck up air. The fix is a good fuel hanger with large pump feeding a surge tank. The surge tank will always be full of fuel under pressure and never run low. This makes sure the racecar always has plenty of fuel volume and supply engine with fuel at all times.

GC8 ❤️

Definitely one of our most favorite builds. We took a 2001 silver 2.5rs automatic. Took everything out and replaced everything with a upgrade. Built STI Engine using our S3+ short block pushing 550whp with a Blouch Dom 3.5 turbo. Swapped in a STI 6speed transmission with ACT twin Disc clutch and STI rear end. All new whiteline control arms, sway bars, bushings from front to back. Kw V3 coilovers with custom made Top Hats. JDM STI gauges and iwire DCCD to control transmission. Then if that wasn't enough the car received a Carbon Fiber Widebody and then painted pearl white.

AOS-R. Keep things clean 🫧

This GR WRX build is almost finished. This Radium AOS-R will keep the engine running clean and free of oil in the intake and IC and turbo. Customer is looking for a good 400whp streetcar. So we are setting him up with our S2+ short block paired with Blouch GT 380XT turbo. This should give quick turbo spool and make 400whp easily. Keeping the temps under control will be a Grimmspeed TMIC and Koyo Rad. Our favorite part about the AOS is its super modern appearance and how it uses AN fittings instead of hose clamps.

Metal Art. ELH = More Power.

There are many header options for Subarus. If you want something that is guaranteed to make more power and handle extreme power and temperatures. We recommend ETS. These headers can handle 1000whp. They are strong and will handle extreme temperatures of track racing. Unlike some other headers these won't Crack on you.

Cleans Up Nice.

Its been nice having "Shamu" around again. We did all that work to bring this car back to Movie Star glory. We plan to enjoy the car for a little. However we are planning on tear everything out and give this car a modern makeover and update.
