Re: Engine hours on RSR sprint engine
Sky
Thank you for the reply. Because of the sprint engine and a host of other modifications that were completed before I purchased, I believe it would run in the unlimited PCA class. I am still aquiring seat time, and thus far have not raced it. I like the car and would not plan on selling it if I did a rebuild. I do not necesarily care about the lowest cost per hour, but care more about fun per hour. I have been spoiled with the current engine, but the car is and would remain much more capable than the driver (me) for at least another 20 to 25 hours. Under the lowest cost scenario the 3.6 cup motor would definately be the way to go, but I may need to change out the ECU if I go that route. I think the 3.6 sprint engine is around 15k more than the 3.6 cup engine.

Re: Engine hours on RSR sprint engine
Tim,
Go with a 3.8 cup build. An rsr engine isn't a cup motor, and you are playing with fire trying to rationalize how long you can go. Btw - the 3.8 cup likely has the same hp as the rsr engine with restrictors. I haven't tried my 4 liter 997 GT3 RSR motor yet, fresh from PMNA - I am sure it is a monster, but the conversion costs alone from a 3.8 rsr motor was close to $80k. Best, F
