Did you know that we have an engine partnership program with our customers?

We are extremely passionate about racing and providing the best service possible to the people who support us. Over time, many of our customers have become long-term partners and close friends.

This weekend, we took the time to officially formalize the benefits, expectations, and structure of the program into a written document so everything is clear and straightforward for everyone involved.

If you are a racing team and interested in joining our partnership program, please read through the document carefully and reach out to us to discuss whether it would be a good fit.

If you are already part of the program, feel free to look it over as well so you can better understand all of the details, expectations, and benefits included in the partnership.

EZ36 tear down for a full build and we found a major issue. A pretty common problem on the EZ engines is for one of the chain tensioner screws to back out. When the screw comes out, it bleeds off oil pressure and in this case the rod bearings were moments away from spinning.

This was a core engine we purchased from a JDM supplier. Luckily we caught it in time during tear down.

If you’re swapping an EZ into your car, make sure you pull the lower oil pan and check for the screw before installing the engine. If the screw is sitting in the pan, send the engine back immediately. If it’s not in the pan, pull the timing cover and red Loctite the tensioner screws on all the tensioners.

This was the only issue we found on the entire engine. Everything else still looked great, but it would not have stayed that way much longer once the rod bearings let go.

Everyone knows our EJ25 SOHC engines, but did you know we also build max effort NA and turbo DOHC setups too? From street cars to full race applications, we’ve got experience across the entire Subaru platform. We also ship worldwide with specialized crating to ensure every engine arrives safely and ready to go.

Aluminum 3D printed EZ36 pan? 🤔 Still working on the baffle. Pan is designed for more capacity with the bolts going through the pan to use all the area of the pan fl**ge for oil capacity.

Monster EZ30R turbo longblock build underway for a high-RPM drift setup! This one is getting the full NAS treatment. 👊

The foundation starts with a closed-deck block, paired with 9.7:1 CP pistons and I-beam rods built to handle serious boost and RPM. The crankshaft will be nitride heat treated and superfinish polished for maximum durability and reduced friction at high engine speeds.

Up top, the heads will receive full port work along with a complete Kelford valvetrain and AVLS delete billet cams designed for aggressive power delivery and sustained RPM. We’re also adding upgraded head studs plus a high-capacity baffled oil pan to keep oil control in check during hard drifting conditions.

This thing is going to be an absolute animal. 🔥 Stay tuned for progress updates!

We’ve got more H6 builds going on right now than ever before, and honestly we can hardly believe it. The support has been incredible. We’re getting absolutely maxed out on shop space and labor capacity 😂

It’s awesome seeing so many people wanting to push the H6 platforms to the next level, and we’re excited to keep building some wild combinations for you guys.

Happy Sunday everyone! Had a great time at Church with the family today, and wanted to share something that really hit home today. Slander has become far too common, and may be one of the most overlooked sins in our day-to-day lives.

“Brothers and sisters, do not slander one another. Anyone who speaks against a brother or sister or judges them speaks against the law and judges it. When you judge the law, you are not keeping it, but sitting in judgment on it.” James 4:11

A good reminder to guard our words, show grace, and focus on lifting others up instead of tearing them down. This is especially true with small businesses—careless words, false claims, or slander can directly affect a family’s income, reputation, and livelihood. Behind many small businesses is a family working hard to provide and serve others.

Enjoy the picture of some big port EJ20 1000+ hp head assembly 🔥
