SBC swaps have been really popular forever.I would say that the 2JZ swap is more popular. I've seen them in S2K's, RX7's....PROBES!!!
Oh yeah LT1>LS1:stirpot:
Compare how long SBC have been around and how long 2JZ's or 13b or any of the good import motors have been around. Pretty sure that SBC have been around for about twice as along.
You can't really say which swap has been the most popular lately cause everyone is comin up with some crazy shit now adays.

^ that's because hicks will try to put a sbc into anything they can get there hands on. I knew of a couple 400hp rotary FC's, if you break it down it's 5hp per cubic inch, 13b's are 80ci. That would be like having over 1500hp in a sbc...how many of them are reliable for a daily driver? A friend of mine drove his FC (which was pretty modded) everyday, even in the winter and the only things that ever went wrong were Mazda's shitty electronics and wiring, it also got 25mpg when he wasnt in boost (which was most of the time) and I think like 11 when he was in it...This argument only works if you are satisfied w/ 400 to 500 whp (or whatever the max that a given import motor can produce...yes, some will produce more than others, I know this) what do you do if you want 700whp or 900whp or more reliably? The cheapest way to get it is through larger displacement in some cases.

Oh my god. Are you serious?Did you just pull out the cubic inch to hp card?
Get off of that. It is bar none, the STUPIDEST riceboy arguement in the world. Thats like me going around saying "Yeah, well if that V8 had a turbo it would STOMP that 4 banger!"
Are you into RC cars? Some of those make 4000 hp If they were an SBC, does that make them superior, or a better option for an RX?
See what I mean? Wasn't that pretty dumb?
You pulled the gas mileage card too? Really? Even though there are V8 cars with MORE power than your friends car that get BETTER gas mileage?
Also, as far as SBC's being swapped into everything becuase they are "hicks", you could say the same thing about Honda owners, or "ricers" if you want to use names, who swap B16FDTTSR's etc etc into X car.
:nonono:
I really wanna see 400whp v8 get anywhere near 26 mpg in town.

Me too.I would like to see a 400 rotary get 26mpg in town as well.
I'm assuming he meant highway.
Im sure a rotary not in boost could do so. Where is Zac when you need him. He would know.

17/25....Thats worse than an LS1 (19/28), only with 65 less hp, and about 120 ftlb's less TQ.
Thats odd....

That's a 13b-rew out of a 93...not an older Turbo II motor out of an FC...which had bigger injectors and stuff, and yes most of that was highway, but still it had much more power than stock. 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...

yeah alot of people assume because its a 1.3 liter that it gets good gas milage, not saying you're one of them but its just kinda funny, i also get wow i bet all the gerbils are running in that thing, and "you know you just dumped oil in your gas", i roll my eyes and say yes, i run pre-mix like a snowmobile.

zac is hiding under a rock! actually hes been working like 14 hour days every day making $20+ an hour, so i dont blame him. 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.
GaryEDIT: 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.

Pre-mixing is better for the engine (rotaries). 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.

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)?
