I’m Curt Brown, and at Curt Brown Racing, I have 25 years of experience in building fast turbocharged street, drag, and road-race cars. With the combination of my knowledge and experience, quality US or Japanese parts, and lower business overhead than competitors, I can give you the best “bang for the buck” in competition machine work and performance parts sales and service.
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 4G63’s head is ported, and over 100 hp increase with a Nissan GTR head.
What do you get for your $$$? A head that works. Not one that's 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!
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!
