The MTM and Sportec cars were in the 3.5-3.7 range. As long as you dont go crazy with the brembos as the 20 inch cast wheels....
My testing would support that..
.... I would say that in an average everyday drive, my MTM is everybit as fast as my 2016 Porsche Panamera Turbo S, at least to 120...
But the MTM has:
Different intake runners
Different Head gastket
Different Turbos
Different Headers and exhaust
Different TCU
Programmable ECU
Im sure I am missing something...in 2003 the bill was over $40K at Joe Hoppens....
But it is reliable and repeatable power...and is an absolute blast to drive....
