People considering buying this car - here is another option.
You can takes Scotts car, rip out the sick 2.5L and drop in a 3L instead. All it will need it a bigger turbo, MAF and injectors. The GT28R it has now is too small for a 3L. (A la warmonger's 3L-Turbo)
Alternatively, like Scott said, you could drop in a healthy 2000+ 2.5L (the 2000's had the thicker ring land pistons which are stronger than the earlier pistons), with the current turbo setup, and call it a day.
