Those cars, while they are cool, are not as nice as you might think. Thats the reason that awd dsm's outsold them like 10:1. The handling is pretty poor on them, the brakes from what i remember aren't very good. The engine is a great engine, comparable to any other turbo 4 cyl out there, 4g63, sr20det, ej20. However as stated modifying them will be quite a chore since almost nobody makes parts for them, it will be a DIY nightmare.
