The research I have done on the net says that the TT Supra and a WS6, both being 6 speeds, are close in the quarter mile and 0-60 times, but top end goes to the Supra, because of the tranny gearing. The Supra can still pull in 5th and 6th gear, as to the LS1 can NOT pull in 6th gear, and actually the Supras 6 gear is lower than the LS1 5th gear. And a rear end gear of 3.08:1 is a better highway gear than the 3.42:1 in the TA.
A Supra can indeed travel 175 plus, as long as it has no speed governor, with a higher redline than the LS1 engine. And aerodynamics are better in the Supra. A WS6 can not top 160 at redline in 5th gear.
Also both cars weigh about the same, also they were both under rated and really have around 340-350 horsepower. As far as RWHP, The TA's seem to have a little higher numbers on the net. But they are real close. Althought the LS1 does win in the torque department, stock vs stock that is. And remember the engine in the Supra is an inline engine, not a V, and I read that a inline engine breaths alot better at high rpms, than a V engine does. Not sure why, but thats what I read.
A race from 30 to 90 would prob go to the TA, a race from 70- 150 would prob go to the Supra. This is just my opinion, taken from the net and differant mags Ive read. Feel free to correct anything Ive messed up on.
A 97 TT 15 aniversary Supra and a 02 WS6 are a very close comparison, The 2jz-gte I6 motor can handle up to 960 horsepower, an LS1 will need an iron block and a few internals changed out to support those numbers. But both cars are very nice cars, I think we can all agree on that.
If I had to drive one of the 2 vehicles every day, I would pick the TA. I need things like dual exhaust and some American rumble coming from the pipes, Although the Coffee can look is cool to.
