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

  • 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
