Head Builds & Porting

Allow your engine to breathe better! With a ported head, your turbocharged engine can breathe better, increasing horsepower and torque across the rev range. This is the affordable alternative to a CNC head, without a downside!

For example, I typically see a 40-50 horsepower increase when a Mitsubishi 4G63ís head is ported, and over 100 hp increase with a GTR head.

What do you get for your $$$? A head that works. Not one thats over-ported or overpriced. I also use US or Japanese-made parts when assembling. No Chinese junk! I can guarantee that my heads will work better than anything on the market.

Keep in mind, this is a mod that is invisible! For GTRs, Nissan will never know!

Manifold Porting

Improve throttle response and increase horsepower and torque without losing bottom-end power!

These units will outperform all other manifolds on the market. I do the work myself, not some $15-an-hour hack in the back of a shop. You can expect quality!

Ceramic Wheel Bearings

For those looking for those couple extra mph in the quarter mile, and beyond!

These ceramic bearing reduce friction, increasing efficiency. Expect an extra 2-3 mph in the quarter mile when used with a sub-11 second car.
