The 2000 Stratus sedan has the Chryco 2.4L, which as said is easily converted to turbo/srt4 spec. srt-4 turbofold bolts on iirc. Stock srt components (i.e. rods and pistons) have held 600whp on dyno before. Even the stock parts would be fairly tough.
The eclipse is going to have a MITSU (NOT chryco) 2.4 sohc, i believe. 4g64 iirc. I guess you could say that motor is not as easy to make HUGE power with because of the head, but it is probably EASIER to get mild power out of because the exhaust manifold is out in the front , easily accessible, and you can bolt the turbo manifold and turbo from a turbo DSM dohc 4g63 onto that sohc head, iirc. If you want to get crazy with it you can also swap on the dohc 4g63 head.
If you dont like the auto in the stratus, swap it. They came 5spd (2.0 only, but same bellhousing and parts) or you can use most of the stuff from a neon as well.
The Mopar/Mitsu 2.0 and 2.4 are a Chrysler design for the short block. Mitsus wear the head backwards - Chryslers have the exhaust to the back and the intake to the front; Mitsus exhaust at the front and intake at the back.
mopar/mitsu is automatically wrong. The 2 2.4s in question are completely different motors. Mitsus wearing the head backwards.. also misleading. The mitsu 2.4 (4g64) wears its head only one way, ever. The 2.0 NON-turbo which is found in 2g dsms (95-99 eclipse, talon, also avenger and sebring) is a Chryco 2.0 DOHC with the intake and exhaust reversed from how they are in the other chryco 2.0 dohc apps (mostly neon). That motor is called the 420a. It's not actually the same head turned around, it is a different casting although the ports are mirror images i believe. The mitsu 2.0 in 2g dsms is an all-mitsu 4g63 motor.
