yeah... that's kind of what I read from Carlos Lopez.

I'm definitely going to go at this point with S5 high comp rotors.

Now I'm going back and forth about going with EFI or carb. If I could get a carb set up pretty cheap, I might just do carb.. If EFI, I know I could go NA now and go FI later and use the EFI.. Hmm.. decisions..

How much do you want to spend Phil?

Sweetness.

I fapped.

It looks nice!!

wait.. I just found out thats the same set up as the picture I post earlier (from Carlos Lopez).

i think you have this backwards. leadings fire at the same time and can be off of one coil and the trailings fire individualy.

look at the schematic(sp?)i posted on the last page trailing has one coil and works with the dizzy, leading has 2 coils one for each plug and fires at the same time. alos after to do this you can switch the way you hook up the dizzy with the trailing. ie plug wire from coil to dizzy you put in the leading spot and the plug wires get plugged in to the leading spots.

I actually ran those throttle bodies (obviously the two rotor, not the three rotor version) on my stock internal 12a motor (with a big honking Master Power 70mm turbo on it, and a Megasquirt controlling EFI) and made 238 RWHP @ 13.5 PSI of boost. They're -fantastic- throttle bodies, and I have the dyno sheets to prove it.

The same exact setup but with my bridgeport 12a yielded 398 horsepower at the flywheel on my engine dyno @ 7psi of boost at 11,250 RPM. So they can definitely breath. (Side note, the engine was practically un-driveable on the road... so.. yeah. What do you expect?)

sorry, i meant the schematic was wrong.

nah the schematic is right. trust me lol.

Herblenny have you thought of this if you go carbed.

WOW!

Actually, I'm going to be building 2 x 20bs. One NA (carb or EFI) and one FI low compression... This is my only chance right now to build both engines.. Once I have the S5 rotors, building will begin this winter... This time, 100%!

how hard would you saw it is to build your own 20b. like buy a core 13b and the parts needed to make a 20b. what i mean is finding the parts.would it be more money then buying a 20b and rebuilding. cause my sa is going to be off the road for a few years and i know i want to replace my 12a with at least a 13b but like every rotary owner i really want a 20b. id really like to keep it carbed.

You are going to have hard time finding 20B specific parts.. ie, one iron and the eshaft.

You could go 3 rotor or 4 rotor by going with aftermarket single piece eshaft and stack 12A or 13Bs. But you would have to go peripheral intake or go renesis irons and housings like the pictured earlier.

Personally, I would go oem 20B for turbo and stackable 3 rotor for NA... reason being, single e shaft doesn't handle high HP as it could twist easier... Think of it as a long wire vs. short.. It takes less force to twist long wire vs shorter one..

I just got off the phone with my builder and we are now shooting for Feb. 09 to get at least one engine built!

im not trying to start an argument, but you are wrong my friend. the leadings are the ones that fire at the same time. take an FD for example, the leading plugs have one coil. two plug wires coming off of one coil and two harness wires going to it(12v+ and signal). then there are two trailing coils. each coil has one wire coming off for a spark plug and two harness wires going to it (again 12v+ and signal) now tell me how it is that the leadings fire independently based on that?

normally i would keep my mouth shut, but running a setup like you have mentioned kills power and on a boosted setup risks blowing the engine(i think you are still na) hell it may blow up an na, i honestly dont know. im just speaking from every car i have built, not a schematic someone drew up.
