Project S13K - Drifting Ability

Project S13k Part Two Dual Pass Radiator

The dual-pass radiator

Technically, Design Craft didn't have to use the dual-pass radiator you see in the images above, but to minimize the costs for the buildup; the team scavenged a C&R dual bypass aluminum unit from Schwartz's previous drift car. "You have to use a radiator with the inlet and outlet on the driver side which will help out a lot because the inlet and outlet on the S2K motor is on the driver side," Castillo said.

To contend with the harsh realities of drifting, an Exedy twin-disc clutch setup was dropped in. A Kaaz two-way limited slip differential was put into place and Schwartz got closer tearing up the tarmac in his newly built S13K hybrid machine. The vehicle was completed and thrown on the dyno a few days before Formula D 2007 Round 6 Drift competition in New Jersey. With boost set to 17 psi, the vehicle used the basemap program from the RS-R drift car, which Design Craft was also responsible in building, and pounded out 357 whp without a hitch with full boost seen at an impressive 3,700 rpm. Currently, Design Craft is working out the minor gremlins they encountered during the drift finals at Irwindale Speedway and hope to make a strong comeback in the next season. Future plans include installing a custom 2.4-liter engine that was stroked and built by Design Craft (covered in Turbo magazine). Competitors be prepared to meet the S13K!

The F22C and its 11-to-1 compression ratio isn't exactly the friendliest setup when it comes to boost. A Cometic 3mm headgasket drops the compression to a more reasonable 8.8-to-1 ratio.

Here's a final look of the completed engine bay.
"The F22C has tons of top end power thanks to its VTEC. In order to get the same amount of top end from an SR20DET you need a bigger turbo and bigger cams, which means you sacrifice bottom end torque," said Schwartz.

Project S13k Part Two B And C Connectors

The only plugs used are the B and C connectors. The B connector controls the map sensor, TPS (throttle position sensor), water temp, air temp and other sensors. The C connector controls the crankshaft sensor, the injector sensor, cam sensors and ignition coils-basically everything to get the engine working. Design Craft used the A and D connector only because they decided to hook up fan control, a map trim knob and a data log switch. That's it folks! There's no rocket science involved in wiring up this bad boy!
