Both would be a good choice. Just depending on preference.

No I didn't. I said which would you rather have for the track (not drag strip)

I never said they couldn't be drag cars/engines.

I like a SBC just as much as any of you yet i like the rotary, guess i am weird

on 20psi the car feels like a solid 10 second car for sure

and just something i wanted to throw out there... there are multiple 1000hp 13bs...... and a boosted 20b will get you your all desired even hp/Tq #s... usually around 500/500 on around 8-10psi

there is is a LS7 powered fd floating around that i saw....... that even gets me wet

when you coming back?

This argument is stupid.

Both engines are great. The main thing is to keep an equal weight distribution front to rear on a very well engineered chassis. Mazda designed a great looking and one of the best handling sports cars of its time with the FD.

Neither engine is bad.
LS1 great power, lots of torque, weighs about the same as a 13b rew.

Turbo Rotary-quirky, smooth, spools turbos very well, can make good power

Now if I were to build my dream FD it would be a 3 rotor N/A. You can make approximately 400 hp. Reliable as hell. Weighs the approximately the same as a 13b rew.

400whp is more than enough for the FD on a large road course. 90% of the drivers on here could barely use the car to its full potential on a track with that sort of power and handling.

Now here is where I am going to catch some shit. The FD is NOT a drag car. Mazda never intended it to rip down the 1/4 mile. Why would they put all that time, money, and effort into the suspension and chassis? They designed it for handling. If you want a rotary drag car, buy a Starlet, backhalf it, and throw a rotary in it. That would be one hell of a scary ride.

Would you rather have a car with instant TQ/Power, or a high reving NA rotory for a track car (not drag)?

The oil-metering system on them doesn't lubricate the seals near as good as pre-mixing. I know many people that pulled the metering system out and pre-mixed 2 stroke oil in when filling up, if I remember right the oiling system uses 4 stroke oil...which is not made to lubricate when being burned. It's not much of a hassle, just put the right amount of oil in a bottle, dump it in and fill it up...maybe a minute longer to fill up.

But, I am not aaginst rotaries at all either, i love em in fact. But when it comes down to it they are WAY too fragile to make serious every day HP with. Like when im screwing with boost and shit, I can just lay into it until i hear some serious audiable knock, turn the boost down a little and im fine. On a rotor, ANY audible knock or detonation is some serious shit, and could be your ticket into a new motor at any time.
Also, when it comes down to it, the reason the rotor makes so much power is because its equivalent to a fuckin 6 cylinder 2- stroke. And yes it is a fuckin 2 stroke i dont care what anybody says. You mix gas, it uses ports instead of valves, and makes a complete combustion cycle in 1 revolution of the cylinder, that my friends is the definition of a 2-stroke. Also, its a 6 banger as it has 6 individual compression chambers.. Im sure every rotary fanboi is gonna try to prove otherwise, but tough shit, it is what it is.
AND, not baggin on zacs car or anything, shit i helped build the damn thing, BUT, If they are supposed to be sooooo badass, how come i can pull on him on a COMPLETELY STOCK motor with a turbo, in a car that weighs exactly 1000lbs more. now my engine in his car? holy fuck that would be fast. imagine ported heads and some bolt ons and it would do 9's on fuckin pump gas any time. I do like the $300 rebuilds he pulls out of his ass though, that would be sweet, and when we tore the motor/ trans out of it in what was it 2 hours at BI that one night, haha, that was fun.
BTW, anyone that wants a cheap swap, you can score a complete 5.3 out of a 1/2 ton silverado for about 7-800$, find a T-56 for $1500 shipped and its a damn good combo. you can buy heads, cam, headers the whole works to swap, and when you blow it, pick up a 6.0L shortblock for $500 or so and you got a 500whp motor no problem, should scale about 2700lbs withthat as well.

EDIT: BTW, wankels dont get good milage because every time we go anywhere we gotta keep the thing over 2500rpm or it will fall on its face, and 80mph is just over 3000rpm as well. I can idle around town and never even touch 2000rpm, 80mph, 2590rpm, and it will be about 2300 next year. PLUS, i scored 24mpg in mine on teh highway, and i held it to the floor a number of times on that trip.

yeah that will prolly never happen at 400 maybe at 200 hp if you're lucky, thiers a reason are car shoot fireballs so easily 😄

I still believe in keeping RX-7's rotaries, if u want 700+ hp just boost a 3 rotor. I like motor swaps, I have them in my cars as well, I just believe in keeping the same companies motor in that companies chassis...Honda motors in honda's and GM motors in GM products, etc...
