Ok...Super 60??

But my turbo is an early T3 off a Lebaron, NOT one of those tiny, pansy-ass mitsubishi turbos.

No...it doesn't sound like you limited yourself to a specific mitsu turbo...it sounds like all of them are pansyass.

Is there any relationship between the DSM 2.0 and the old 2.2/2.5 platform? I know a 2.0 DOHC neon head will bolt up, but I'm not clear on the progression of the block styles and the relations between them.

The DSM block, as in the 4g63, bears no resemblance to the chrysler blocks you are talking about...it is a mitusbishi engine.

Now the chrysler blocks that came in the n/t 2nd gen eclipses, the dohc 2.0, aka the 420a is also probably not very similar.

I was reading up on the 2.2 used in the turbo1 and turbo2 and it sounds like that is a pretty good block. I know you talked about the lotus head found on the turbo3 and that seemd like it would be hard to find. The dohc head of the 420a, as you said, will bolt up, but I don't know how easy that is to do.

If you have th 2.5 liter turbo1 that came out in 89 it is rated at 150hp. Intercooling it and increasing the boost a bit is probably going to net a big gain. Same thing if you have the 2.2.

I think whichever block you have is going to be fine. The sohc head might be limiting....but build it and b00st big.....that will sovle the problem.

*edit

What you should really look into is it the current 2.4 turbo chrysler engines...that would be a bad ass swap.
