I've been working with Clint on my Subaru STI build and he has been extremely helpful on helping me building my engine. Everyone knows their stuff here and highly recommend them to anybody for a performance need. I wouldn't go anywhere else and can't wait 4 my next build after this one.

Absolutely amazing! For someone who had trouble articulating exactly what I needed on my 2021 WRX limited they offered great options and explanations without being pushy. Will definitely come back for next stage

Did an amazing job and helped me out with my lifter and manifold problems when everyone else was too scared to try due to the age of the engine and rusty old bolts. They even fit me in and completed the work during the holidays! I trust them with all my engine and performance work.

These guys are the absolute best! Clint and Tony both helped me out immensely with some issues I had with my b25 cylinder heads. They also build kickass shortblocks for Subarus. I just wish they were local to me. Still won't hesitate to do business with them again in spite of being across the country from them!! Thanks guys!

One of the best shops I’ve been too. Professional, reliable, and very knowledgeable staff that answered any questions I had. Tuned my stock motor 06 Wrx and put up 413hp. Couldn’t be happier!
