i've looked and the AA kits are up to $10,000. Knowing how much turbo's cost from wanting to mod the eclipse, i'm not wanting to pay 10 grand. I went the the AGP website and found a kickass setup for a turbo good up to 500 hp for about 1,600. The only thing I really need to find is a custom manifold for the BMW. Then I need to find an intercooler (which is about 1,000) that can fit into a BMW bumper. If needed, I can always cut and mold the bumper around the intercooler. Then I need an exhaust system. After that comes piping which shouldn't be the hardest thing to do. Then of course comes the CBV, air filter, external wastegate, injectors, fuel pump, boost controller, etc. Really, when you think about it, the turbo is the main concern on how much horsepower you get. So why I should pay up to 10,000 when I can spend half as much just by knowing what I need. And the funny thing too, on the AA website the use a Mitsubishi TD06 Turbo. Basically they charge you a ton of money for stuff that if you researched you could do yourself. I do admit the custom piping, ECU and manifold is something that cant be done as easily by youself, but there is no reason to pay that much. If I were to buy anything from AA, it would be the exhaust, computer software, and piping. I can get the turbo and other stuff anywhere else.
Back to my one question, how much power can the M3 engine produce without having to change stock internals? If I can get up to 500bhp without touching the engine, then this project will be cheap. Because AA seems to make the kits as bolt ons without any cams, pistons, etc. included in the package. For 10 grand i'd expect some engine work to be done as well but i guess not. I just see AA as an alternative for really rich people to just blow the money. I'd rather save the money and put it into a bodykit or something like that. AGP turbo
The turbo's they have there are ball bearing turbo's and produce minimal lag with reaching full boost at lower RPM's. I'd rather pick out my turbo myself instead of getting whatever is in the kit and then boost as much as I feel necessary.
