honest advise.
 

SR20det or RB20det?

SR20, it's easier.

Redtop or black?

Whatever your budget allows.

Honest advice indeed. Listen to it.

also really depends on budget and what your goals are :) sr20 is easier

lets say money wasn't a problem... i would say rb, but sr is easy er, cheap er, new er, light er, an it depends on what sr ur thinkin about to tho. personaly if u got the money and r lookin for the most power or whatnot i would go wit rb otherwise the sr:thumb: i loved my rb like nothing else. but thats just my opinion, someones probably gona say something different

just go sr..buy a redtop..rebuild it..have fun..its that easy

My advice, search and figure out which is best for what you want and your budget, and next time please post in the correct section.
