From wat i have heard 420's aren't very reliable at all. A guy I knew from around had one that is identical to tha one in FLneonRT's sig. But from wat other people told me he had tons of problems with his setup and motor! 420's are not reliable motors IMO if u can afford it go with the 2.4 that is in the SRT_4

 

^not always... you have to do a 2.0 right tho, u cant just slap parts on it

and the 2.4 is harder b/c its already turbo so u dont have to mess w/ 3/4 the stuff u do w/ a 2.0
