It wouldn't suprise me.
I would rather a rotor than a shitty LS1

@Pezzletism you sir are an Idiot!

does anyone know hoe fuel efficent these engines are???

Miss my old Rx7 which was destroyed in an accident! It looked exactly like this one! It sucks they stopped producing the Rx7 though. Would definitely own one!
-
that looks like a 3-rotor could be wrong.

@Pezzletism lol you realize the only difference between the 20b and a 13b is 1 exta rotor and its housings, right? its not a lot more weight, and it signifigantly increases power. its definitely worth it.
-
do you know whats the RPM on that?

@botchla90393 I'm pretty sure the 20B would be a decent bit heavier than a 13B, it's essentially 50% more engine, the extra Rotor and housing, an extra center plate and longer e-shaft, plus all the other kit needed, injectors, coils and such. That said you can get a lot more power from a 20B, and more reliably too. The only annoyance with a 20B over the 13B for me would be mounting it far enough back to keep the weight balance in the car, especially for track work.

@smithythefierce The Ls1 is no where near shitty. It is a solid platform that responds very well to modifications.

This car would blow the door skins off an ls1 powered fag mobile

@Baronvontrap yea revisions of intake and fuel induction , plus it adds some nicer touches like mirrors and those beaqutiful s5 taillights
This comment has received too many negative votes show
That rx-7 will be going slower with a 20b because its so heavy, he's better off with the 13b

Wrong. The 20b doesn't weigh that much more then the 13b. Plus it makes a lot more power then a 13b.
