  • SR20DET motorsports success

    Looking for some first hand feedback on how competitive a 240sx with an SR is. Ideally in NASA ST3 or ST2.

    I figure Corvettes will have more torque especially low which will also probably lead to fewer shifts, but maybe I can outdrive them in the corners. And I suspect 240sx will be cheaper on consumables than Corvette.

    I read for STU - not encouraging.

    Keep in mind that for STU, the car has to run on a stock turbo with an inlet restrictor. That's completely different than a power/weight class where you can run an aftermarket turbo with no restrictor and tune your power curve with turbo/cam/boost settings.. for STU, you run as much boost as you can till the turbo starts sucking wind. Gives you a lot of torque coming out of the turns, but you run out of air at the top end and an N/A car with similar HP levels will catch/pull you on long straights. The turbo has advantage on short tracks because of the fatter midrange and corner-exit torque. (You can get in front of an NA car on the straight and then hey have to pass you in braking/turns.)
