RWhp is horsepower at the rear wheels...for example, the power directly measured on a chassis dyno. HP measured on an engine dyno is power at the crank...before driveline losses. With a manual transmission, driveline losses are about 15%. With an auto, losses can be anywhere from 20%-30%.

Turbo timing alterations aren't necessary but you can raise the boost and get it to about 400rwhp (about 470hp at the crank, which is a great increase over 320hp) without changing the turbos! You can read more about 'bpu' here:

Maintenance records and driving habits of former owner(s) is critical when looking at a Supra TT with some miles on it already. You'll want to have it professionally inspected by an objective, qualified, and above all experienced Supra mechanic before you purchase it.

Why do you think 98 models are best?
