Both are 2017 STi’s, but the one on the right is getting the PSI built turbo kit. It’s pretty awesome when a customer brings in a practically brand new car for a cool build. The engine is being left stock… for now, but it’s getting the turbo treatment with a big ole Precision turbo.

The plan is to have all the intercooler piping powder coated wrinkle black, and the header & up-pipe ceramic coated by JT Coating. It’ll have a nice clean look, especially with the shaved and powder coated intake manifold. This setup will be pushing it for a stock motor, but I foresee this car getting a built engine in the near future. Here’s a few pics of the fabrication process.

Some mocking up happening right here

All back from coating and looking fresh! JT coating killed it on this one. Big thanks to them!

Everything is getting bolted up and it’s looking good. I’m really digging the wrinkle black powder coating on the compressor housing, intercooler pipes, and manifold. It keeps the car looking brand new and almost stock at first glance.

After getting finished up and tuned by Anthony, it made 388whp and 358wtq at 16 psi! This turbo set-up is capable of a good amount more, but we kept it safe due to the stock engine and clutch.

Here’s a dyno graph comparing the car when it was stock and after we finished up with the turbo kit and tune. You can see the massive difference in power. With our big tube UEL header, the 5858 Precision turbo hits full boost only 300 RPM past that of a stock STi. Having that much more exhaust flow played a huge role in making these kind of numbers that early in the RPM range.  With a built engine and upgraded clutch, this kit will be ready to handle a bunch more power.  A big thanks to Mike for bringing us this project, and we hope to see him and his STi back soon!
