well there is the Mitsubishi 3.0 from the diamonte (sp?) which is basically a direct bolt up to the V6 A604 tranny. There is also the 3.5 from the montero, but that swap is a lot more complicated. If your venge is an I4 i would go the turbo route. The 2.0 I4 avengers shared the same engine with the eclipse from those years so they can share the same parts such as turbo kits and anything else you may have in mind. the suspension components however were not interchangable b/c of weight differences.
