the STS system is good. I've played with one taht i actually purcahsed for arace car (i'm the sponsor, well my company is anyway) Its actually ebign used on a honda f3 engine and its goign in an FSAE car that a buddy of mine is biulding. So far i am the "corporate sponsor" and my $400 donation (a total tax write off cus its to columbia university) is all they got. The STS system is VERY flexible but isnt; exactly a slap it on and go system. It will require soem engineering. Not sure if thats what yoru looking to do. But for eth f3 engine its great cus it was carb engine engine taht has been comnverted to an EFI turbocharged car engine.
