I was talking with a 914 owner about engines and the cost-benefit of a Subaru swap. This person is looking to build a street-legal car that will serve for track duty. But AFAIK, PCA has restrictions on non-Porsche engine participation.
So, since I know most of you all are far more familiar with the regulations and options than I am, I'm looking for information on what sorts of restrictions does PCA place on non-Porsche engine swaps? What other options for track days are available (nationally, but SF Bay Area specifically)? Is building a non-PCA-legal car a shot in the foot? Or is PCA somewhat irrelevant because of availability of other options? What are your thoughts here? And I'm looking specifically at track days, and not autocrosses, but I'm interested in learning about AX info as well. |

And I'm looking specifically at track days, and not autocrosses, but I'm interested in learning about AX info as well. The 2.5L Subaru turbo is a good swap to replace the 4 cyl Porsche engine. The Subi is shorter, narrower and weighs only 25 lbs. more than the 4 cyl Porsche. I bought a complete 2007 WRX Turbo with 10,000 miles for $3,300. The adapter from Kennedy engineering adapts the engine to the 901 transaxle. Putting a radiator up front is not too big a job. The bottom line is power and torque for a reasonable cost. I currently have 430 HP and unbelievable torque from that little engine. Later this year I plan to install a larger turbo and larger injectors which will give me an additional 120 HP. My car is strictly a track car. I run SCCA races in Improved Touring (ITE). I also drive with GGR in DE, but can not run in the PCA races because of the Subie engine. GGR has not had a problem with other cars than Porsche running the DE events. In addition, I drive track days with Hooked on Driving, Trackmasters, Northern California Racing Club, and may run some with NASA in the future. If you want a state of the art reliable engine, the Subie is the way to go. Let me know if you have any questions. I will be glad to answer them. |
