Daily Slideshow: F22C Has No Issue Putting Out 500HP Daily
The S2000 has been the car that many Honda enthusiasts aspire to and this owner was no different. See what Amrit did with this AP2 CR inside.
Keeping it in the family
This 2008 Club Racer is Amrit Soos's second Honda build after a high horsepower Integra. “I wanted to do something different with this build. My turbocharged Integra project car made 900 horsepower but was designed to go in a straight line and the onset of power wasn’t very streetable. For this build, I wanted something that would be fast. Something that I could drive every day that would handle like a champ.”
You need a good foundation
Amrit had a great baseline to start with on the CR since the car comes with improved sway bars, a faster steering ratio, bushings, improved aero and the factory option to delete certain creature comforts for improved curb weight. With a sports car that handles wonderfully with amazing balance, there is just one thing to improve on: power.
What's under the hood
The F22C is the engine found in the S2000 models from the year 2004 on and features a longer stroke than the F20C used in older S2000s. The F22C longblock is mostly stock but a 3mm head gasket lowers the compression ratio and ARP head studs that keep the head and block clamped together.
Where did the money go?
When it came for Amrit to add more umph to the F22C the choice was made to go with turbochargers. An inline Pro exhaust manifold bolted to the cylinder head postiions a Garrett GT3582R turbocharger sitting between the block and the passenger side shock tower. A J's Racing 70RR titanium exhaust is out back while custom piping joins the compressor outlet and Precision Turbo & Engine intercooler.
Numbers don't lie
The fuel delivery system has gotten an upgrade so that an adequate amount of fuel may be delivered to the Injector Dynamics ID1000 injectors from an Inline Pro fuel rail. The factory injectors were just 360 cc/min compared to the new 1,000 cc/min new ones. A tuning solution had to be set so that the engine could accommodate the new injector size and still be able to control the drive by wire system. Hondata offered a K-PRO piggyback solution by way of an adapter harness that enables the factory ECU to remain in place. The boost pressure for the turbo is set at 15 psi, the fuel and ignition are set for the larger injectors and the Okada Projects Plasma Direct Ignition coils.
