    XR4: I think the fuel cell rule could be changed to something like the new AS OEM fuel tank rule. I will submit it to the CRB. IT cars can run OEM tanks in STO/U.

    Z3: I misstated, intakes must be OEM. Yours is legal. Wild West! If your car has a 2.8 it has a base weight of 3080 with driver.

    Peter: the STU rules state "Intake requirements. All cars shall use the installed engine’s stock air metering device (e.g. throttle body) and intake manifold, unless noted otherwise."

    He has a 2.8L M52 engine with the intake manifold from a 2.5L M50. In other words, it's not the "installed engine's stock intake manifold." Therefore, it's not legal.

    I am unable to find the archieved rules for Speedvision circa 2001, but I'm certain that it was allowed at the time in both the e-36 and e-46 328's. I can't imagine that such a swap would be able to fly under the radar of a successful pro-racing effort. Again, no worrys though because I'm going to be ITR legal which makes me eligable for a 280 lb weight break.

    Or I could put the correct manifold on and run ITR and weigh 2800lbs. Less ballast and I don't have to worry about fab-ing a custom rear suspenson to replace my semi-trailing arm suspension.
