dont listen 2 him bud. turbo bolts on fine, did it in a day with a mate.. Only thing u gotta do is block some oil return lines n rotate the wastegate 2 fit as it hits on ur suspension tower in the engine bay.. The turbo is quite laggy, but that has 2 be expected if ur not planning on doing other mods 2 go with it. Mine comes on boost at about 3,800 n full boost by about 5,000. No need for a flash manifold, however u may aswell get one i spose as i had 2 rip the heatshield off the stock one 2 make it fit.. So it looks 'average' lol.
Anyways unless your going 2 spend a lil more money besides the turbo.. U probably wont get alot out of it as you wanted. The dump pipe that KKR makes is 2 small aswell, its on my car n its a V band flange or wateva its called.. It needs 2 be larger so thats the only downfall ive found with it. Ive had the turbo on my car for about 4-5months now n have had no trouble at all with it. Am only running a low 10psi/12psi though.
Good luck with your turbo set up,
Steve.
