umm.. no not really LMAO
they're laggy, some decent boost only hits at like 5k
they're the same as any other a70, just most are narrowbody, and i think an 1" or 2 don't really make that much diff on weight
and they're identical lengths to any other supra
only diff they have... is a small engine lol
stock 1ggte just dyno'd on 14psi running pig rich (admittedly boost leak or something) but got a massive 150hp @ the wheels
a friend of mine when he had just an exhaust on his 1g dyno'd on 6psi and got 170whp, was well impressed with his...
but mostly they're laggy... get some decent i/c pipes & i/c and it'd go better, but the turbines are just heavy as hell which = lag
