You can do some searching if you want to see it in action;)

^boot boot boot! reminds me of a whoopee cushion

They can do 2 cams per rotor so you can have a 6 cam engine :eek:
Also, I hear that if you replace the valves & valve springs with titanium units you get 40% more power :eek:

What kind of mileage do FD's get? I was seriously considering purchasing a JDM version.

I got about 400-450k on one tank... but mine is single turbo and that's just average day to day driving with a lot of highway.

just in the city approx 350ish and if I was out for a trackday I got like 3 20 min sessions on one tank.

I will lol if someone uses this info on their friends.
hah

The 20b is an awesome engine as far as power is concerned. They can make a lot of power when boosted. Rotory engines have 2 downfalls.

One is reliability. They are a very sensitive to detonation. One good engine ping can crack an apex seal, requiring a rebuild. There are some good quality aftermarket apex seals available that can improve the reliability issue.

The 2nd downfall is how inefficient the engines are. They have a very high Brake Specific Fuel Consumption, meaning that they require more fuel to produce the same power a piston engine makes. Although 13b's and 20b's are 1.3L's and 2.0L's respectively, they flow 1.5-2 times the amount of air a piston engine does with the same displacement. In other words a 20b engine has the equivalent airflow of a 4L piston engine. This is good for turbo spool meaning that you can spool big turbo's quickly, but because of the poor efficiency it won't make as much power as a piston engine.

We are building 2 cars right now with 20b engines. One is a FD RX-7 with a streetport running a GT42R Turbo with individual Blaster Coils, Haltech Platinum EMS, and Custom Air to Water Intercooler.
The other is a Stock 20b swapped into a FC RX-7.

I'll post some Dyno #'s as soon as we get them on the dyno

I know some people have built r26b's by combining 2 13b's together or having a 20b and adding another rotor housing rotor..etc, but what about a 40B, i wonder how difficult that would be to build. Maybe by combining 2 20b's making it a 6rotor... just think of the possibilities.

You know what?? Combine two 40b would make 80b! OMGWTFBBQ

and the final questoin is, is rotary really superior than piston engines?

In theory, yes. in practice, not necessarily.

Lots of love for rotary engines though. My FC was my favorite car I've ever had.

Definately not superior. If that were the case you would see them on most cars built today.

I don't care enough to know about it lol...

all i know is some kid has an FD in MT3/3DX called 787B...

the reading kids do these days... maybe if they crawled underneath a fucking car, and maybe (if a dsm) into it... they'd learn something other than

"wahh diu... GT-ARLOOO ar... ho fai in straight worrr~~~ but that 7jai's gonna rape it in the corners!"
