my buddy had an '03 Srt-4 awhile back with a stage 1 kit. a stock bad boy neon might not be an evo, but it is a mean machine. the neon/pt cruiser 2.0 and 2.4 block shares its basic architecture with the old k car 2.2/2.5 (but starter is on opposite side of block). the dimensions (bore and stroke) are very similar to the mitsu 2.0 and 2.4 respectively. then you have the hyundai world engine 2.4 (piece of junk) and people are easily confused 'cause chrysler used that in the caliber instead of running the pt cruiser 2.4 n/a.
an srt-4 power plant in a d50/mm had crossed my mind. but you had the same problem with any other non-mitsu based swap, you have to custom fab to install it. there is a dodge/jeep rwd trans and bell housing that will fit the neon/pt engines.
