choosing the best motor

I usually hang out in the street racing forum, but i feel you guys could help me more. I just got through stripping out my 87 dodge daytona and i'm going to make it a drag car only, not street legal. I've got my heart set on the 2.2L turbo from chrysler because i can get a lot out of it and it's cheap to work on compared to a lot of other motors out there. My friend has a 420a motor from his eclipse he is offering me. i hear the 420a isn't very reliable. plus i found a good website to buy parts from if i go with the 2.2 turbo at turbosunleashed.com. Just wondering what y'alls opinions are about this. thanks
