good find. great info but alittle out of date. newest stuff i saw browsing through it was a 3000gt, a crx, a tuned port camaro and other early 90’s cars. someone needs to make a newer version since the gt garretts and other ball bearing turbos came out. gt wheels are way more efficient. tuning is outdated in here as well.
