Mikey has been wanting to turbocharge his RSX for a long time. Over the past winter, he put lots of effort into this project, fabricating many of his own parts. In the end, everything came together very nicely to produce a car with a strong and wide powerband.


The parts:

• Garret T3/T04E 57 trim turbo
• Bosch 750cc injectors
• Hondata K-Pro
• Treadstone manifold
• custom downpipe
• AEM 3-port boost control solenoid

The results:
294.3 hp @ 8000rpm and 207.0 ft-lbs @ 6500rpm


The short story is that Mikey put a turbo on his car and picked up 109.3 hp and 71.7 ft-lbs over the old NA numbers at only 10psi. A higher-reading MAP sensor is on it’s way, so a bit more power will be made soon.

Compared to his last NA numbers:

This car belongs to Jan (say it with me, “Yahn”). While there are some big plans for this car in the future, it currently serves duty as Jan’s fun daily driver.


The parts:

• Crucial uppipe
• Titek downpipe
• Greddy exhaust with muffler delete
• Samco turbo inlet
• K&N Typhoon short-ram intake
• STi TMIC
• 3-port boost control solenoid

The results:
213.8 hp @ 5500rpm and 235 ft-lbs @ 3750rpm

As compared to our stock 2006 STi baseline:

The parts:

• Turbo XS uppipe
• HKS downpipe – new bellmouth design
• Vibrant catback exhaust
• 3-port boost control solenoid

The good:

• The mechanical work was done by Jan and Angel
• The car was CLEAN

The bad:

• I don’t think the uppipe did anything. It may have even slightly hurt spool-up.
• I’d recommend a fuel pump

The results:
261.7 hp @ 5000rpm and 300.8 ft-lbs @ 3750rpm

Very typical numbers for a stage 2 STi.
