Just picked up an EJ253 short block from these guys for my Forester. Awesome dudes, awesome shop, block looks great and spins good! I had about a thousand questions and everything was cleared up! Would for sure buy another block again if I needed to, maybe for my Sti. Just wanted to say thanks again to GCH, and if you’re thinking about buying a block from here, do it!

The short block I ordered was really well made and delivered pretty quickly...Their blocks are extremely well made and I will definitely be a return customer.

I bought a B25 Sti bare right cylinder head with the option to not have port and polish, and it’s a very high quality part and meets my standards. It’s going to work perfectly for my top end build and I’m glad I bought from GCH. They have high quality parts and I recommend everyone to check out their website.

Ordered a Fa20 short block recently and have been super happy with the results! The staff was great with quick responses and were able to put me on the right track for my build. With the quality and price of their products, you really can’t go wrong here!

Absolutely awesome staff and unbeatable prices. They were able to get me the parts I needed for my rebuild during the holiday season and get it out in a very timely manner. Definitely a lifelong customer!

Purchased an upgraded stage 1 long block about a year ago. Currently pushing 430whp and 8,000+ miles into the motor. Built this motor for racing at the track and have done just that! Excellent customer service with some of the best build qualities out there. If anyone was looking into GCH for a motor, I’d highly recommend it!

Unbeatable prices and solid customer service. They made a minor mistake with my order and corrected it very quickly and efficiently with no problem! Gabe was awesome to work with. Would definitely recommend to anyone building their car up.
