dont mess with nskilne95. I work with this guy and he knows what hes talking about. You would think he built the frickin motor with the way he goes on about it. Ive looked into both motors and find that the rb25 is much better then the sr20. Especially for the amount of money hes puttin into it. And seeing as how he started this post with a question and got a bunch of bs from alot (not all) people that just proves that most of you are all talk. So when you c this 240 on the road lets c how you talk then.
