diff btwn 13b, 20b

hey what is the difference between a 13b and 20b? and how hard is it to get either of the two. is it cheaper to put a renesis into an rx-7?

an extra rotor...and a lot of $...thats the difference

learn to walk before trying to run.
go study.. www.rx7club.com (http://www.rx7club.com) and also, why would you want to put a renesis in an rx7 ? to have some nice hp numbers but the same insignifiant torque curve a DX civic has? turbo is the way to go.
and the FD3S engines are more powerfull than the renesis is. the 20b is a complete other story, dont think about it unless you have 20k$ to spend on your engine.

thnx for the info im a real n00b when it comes to rotary engines

when it comes to searching too

Ouch.

"yeah, when it comes to searching too. im a stupid nerd who only has time to make fun of ppl who ask questions on boards." dont talk trash u stupid ricer, i was just asking a question, if id had wanted to search for some info i wouldve, but i did the smart thing and just asked ppl instead, which is faster. "hi my name is D3rE-Lickmydick, u should just spend hours looking for answers to your questions because thats what i did, and look at me, i know everything there is to know about rx-7s, no ive never heard of sex, is that a new kind of engine, hold on, ill be back in a few days, im gonna go read about it"

ricer thats a bit harsh dont say things you dont know.
