Chrysler Conquest TSi/Mitsubishi Starion ESi-R
A big block will not fit, unfortunately. Just too wide.
That did give me another idea though... instead of the stock build that produces maybe 250-300hp (Mopar 360, with intake, cam, etc. stock otherwise) I could use the built Pontiac 400 that I had built for the red Trans Am. I did some rough measurements in the dark, and the engine mounting locations on the 400 would actually be BETTER to mount in the Conquest. No frame cutting would be needed, but with the 360 I would need to cut the frame and extend it forward to make it possible to mount the 360.
Hmmmmmmm.
As for there being a kit made for them, nope. All custom, but there are guys that have done smallblock Ford swaps, smallblock Chevy swaps, etc. I don't think anyone has done a Pontiac swap, though.
