so if my trans is good right now just leave it alone and get a clutch??? cuz i herd that a mits trans can only hold up to 250 hp..... or is that rong???

you dont have a mitsu trans you have a chrysler trans. The trans on the 4g has held into the 10s and I know the 420a neons can hangle 500+hp on the stock trans but I dont know about eclipses

You seem to have left that little piece of information out. I change my answer now. Unless you build that motor up, it won't last long now that you turboed it and want to run nitrous. The 420a just won't handle it unless built right.

Drop the compression a couple points too when you build it. Right now you got a high compression engine running boost and if sprayed, will blow something up. That's more then a stock 420a can handle from the factory.

Yeah, I agree with Dave. I would probably go 8.5:1, that seems to be a pretty good number.
