yes you need them, and yes leave the stock ones with stock turbo.

........ YES you need those items. The good news is that they almost always come with the motor.

i guess to answer that you need to ask yourself this - do you want lots of compressor surge and do you want to run unlimited boost?

anyway try reading about turbos - the book Maximum boost by Corky Bell is a good one

oh and mello88 i believe you left one of these out

Man you can't just run more boost lol It takes alot to do so..and on an rb20 a tune and 12psi is what you can run safely on the stock setup....with the injectors screaming for mercy.
