HPI has road tested an NA GTS25 against an NA Supra, their figures show 0-100 in 7.3 and 1/4 mile in 15.5 which is accurate in my case cos ive done my 0-100 in just under that time and the quarter sounds right. the car made 105 kw at the wheels, this is stocko with a muffler i think, pretty good i guess, id like 150 at the wheels on mine
