I would tend to disagree on the power potential part. Problem is, most people compare OEM MHIs against aftermarket Garretts.Originally Posted by Turbo_Steve
Take for example, the TD05H-16G7 on the evo 3. The record on that turbo is 490whp @ 31psi boost. true it was pushing it well beyond its efficiency, but unlike some of the garretts it HELD up with such heavy abuse for a few racing seasons.
I definitely wouldn't go garrett route on most of these cars, since there are bolt on MHIs...which can be rebuilt. Just look at the prefered set of turbos on 300ZXs and 3000GTs in the US....there are quite a few running 9s on a pair of Evo 3 turbos. Even JUN opted for a TD05-18G for the 900whp 350Z
