My Uncle has a 93 FD With The 20b 3 Rotor Swap in it.. and the thing is a beast with the turbo ugrade he is actually pushing a little over 500hp with only 13pounds of boost... and he still hasnt gone full stand alone yet... so i guess i will be the first to say i prefer the rotary over the V8.... Especially with the 3 rotor.. .. and he is handing out *** wuppins to the V8's. not talkin **** juss sayin...

If money is an issue... heres the list...

20B motor - $4,000 (w/cpu harness and stock twin turbos)
Rebuild Kit - $1,300 ( Atkins)
Motor Mounts - $50 (custom fabricated)
Kept stock RX7 tranni - FREE (barely)
two walboro fuel pumps - $200
Aeromotive FPR - $200
Stock Injectors -
Garrett 60-1 turbo - $1100
Custom Turbo Manifold - $150

Add it all up - $7000

Future Plans... Microtech Lt12x - $1200
then we will be seeing upwards of 700hp... IF YOU DONT KNOW... U BETTA ASK SOMEBODY!!!
AND IT RUNS LIKE A CHAMP WITH THE SORRY STOCK ECU... ITS JUST A LIL CRAZY...

ROTARY ALL THE WAY BABY...!!!! ITS WAT THE RX7 WAS BUILT FOR... NOT FOR A LSNONE

I LIKE THIS GUY!!!

thats assuming you have a lift and everything to install it yourself. you also forgot some of us would like to drive them more than just on the weekends and at the track, so lets put gas mileage into the equation. do you really think you cant get a v8 to be pushing 500 hp? i prefer the stability, power, gas mileage, RELIABILITY, and sound of a v8 to any rotary any day.

Insanity

you know the worlds fastest car does zero to sixty in a second and uses a v8?

turbotommy is a tool.

What car is that?

BTW......did you know that every other car in the world doesn't use a wankel rotary engine? Hmm.....I wonder if that makes a difference.

1.) its a modified Vauxhall Victor, i think its a twin turboed v8 with nos

2.) yeah, id say its because its terrible with gas, torque, oil, and usually reliability? wouldnt it suck if every car had a rotary?

Roen

2. Nah, cuz then there would be no basis of comparison! Also, the rotary would have much more development and we'd probably see hydrogen/electric hybrids by now.

Besides, I don't mind the loss of torque down low since the torque doesn't drop off as fast up top than piston cars. I get pretty decent gas mileage, and I know others have claimed to, at least, hit anywhere from 28-33 mpg highway. I've even verified 24 mpg city. Those numbers are pretty much on par with V8's anyway. There's a thread about it in the second gen section. The oil's not a big deal, really, 1 quart per 1000 miles? I can deal with that.

Really, it's only the reliability that's a concern since any boosted engine, piston or rotary, is less reliable than their NA bretheren. Then again, you are trying to make power out of a 1.3/2.6/3.9L engine vs. having a 5.7L. This argument really just falls under the what's a better engine to have, a small engine or a big engine?

Personally, I like the revving of a small engine, and the ability to hold a gear as I enter a corner, but that's just me. I'm a more entrance-oriented driver anyway, as I love passing in corners, rather than on straights. Makes me feel like I did some of the work, not just the car. The torque of a V8 definitely helps in the exit though.

Has anyone ever swapped a V-6 of any manufacture into the rx-7?

illtakeyochik

Your right... youR super correct... but if you slow down and look at the time that mechanics and everyone in the world has had to PERFECT the ***** piston motor... you will see that it basicly QUADRUPLES THE TIME WE ROTOR HEADS HAVE HAD TO PERFECT OUR MOTOR... now that being said... we had less than half the time you guys have had... and we have half the engine size... and less than half of the aftermarket parts you can buy... THERE IS NO FORGED ROTOR... There is nothing you can do to the ROTARY ENGINE THAT WILL MAKE IT A STROKER (thats homo as hell by the way)... we have mazda factory parts and we are running the times YOU are in the quarter mile.... yes 13b's and 12a's are up there with you guys... and i dont wanna take it to the 20B(3rotor) or 26B(4rotor) level yet... so before you hate the rotary understand that the lil motor is growing fast.. very very fast ok... just take the time to look else where...

OH AND DONT HATE SOMETHING YOU DONT KNOW **** ABOUT!!!!

look who's talking.

and your little motor is not that small coming in at 3.9L

the only ones i recall seeing are nissan v6's (maxima and 300zx engines- same? vq30de? not sure), and for big ponies- the buick GNX turbo v6.

Insanity

dude, who brought up the amount of time you rotor heads have had to improve the rotary in the first place? thats not the question at hand. what i was talking about is the ability to use the rotary as a day to day, or at least something close to that, and still be able to have a fierce car. i guess you could dump alot of money into it and put a brand new engine, computer, downpipe, mdipipe, cat, maybe suspension, and run with like 320 or 330 to the wheel, but how much does that cost? where as you could also dump in a v8, which weighs 15 pounds less than the rotary, turboes and everything you pull out, a stronger tranny than mazda makes, and make easily 100 to 150 hp more? you can beat the **** out of a v8 and it will still get better gas mileage than a rotary. the rotary is an incredibly small engine, what do you think happens when you put alot of boost on it? it becomes very unstable, very quickly, and it has to rev high. its almost as if you honestly dont think you can get a v8 to be pumping 600hp+ or 700hp+. and btw, are you just arguing out of spite for your uncles rx7 or do you own one yourself?

roen i think they actually do have hyrdogen based rotaries out they were planning on bringing to some rx8s. im not sure exactly of the gas mileage or power, but they said they were trying.

i totally get what you mean when you say your an entrance based driver, and thats cool. but im more of an exit based driver, and i would feel better if i knew that my car could make the torque and power to get out of a corner quickly, because in all honesty thats where the corner is determined, you know what i mean?

Roen

iTrader: (2)

I agree, unless I put my car out in front of yours in a pass, and stop you from using your torque. Once, we get to the next corner, I have clean air to work with. That's how I get a lot of people. But, that's all situational anyway.

Hydrogen is nice, but I think they determined that it's energy-inefficient.

3rdGEN4MI

Where do you get the engine mounts for these swaps?

Insanity

yeah i guess if the track was narrow enough to where i couldnt go around you on a straight and assuming you somehow did get in front of me, guess it depends on the track. i understand what your saying but dont get what youre referencing to with the "i like energy" part. i dont really foresee a rotary with good gas mileage, good in comparison to piston motors of the same modern technology.

wreckless-7

this thread is going nowhere. the 787b uses a rotary and whooped everything around. there are plenty of v8s that kick ***. both v8s and rotarys sound amazing.( rotary sound better actually). its what ever route u wanna take. one thing everyone can agree on....RX-7S KICK ***....

I own an R1 FD. I also own a Supercharged LS1 C5. The Rotary is smoother, but it has nothing else over the Ls1. I took a trip up to Los Angeles with a couple of SR20 240sx's a couple weekends ago, and ripped off a 29.3mpg average driving 80-85mph.

The C5 has 116k miles and is my daily driver. The FD has 79k miles, and I'm crossing my fingers everyday I decide to drive her, that nothing fails.

Once I sell my S13, I'm shooting for an LS3 swap for the FD. I'm tired of stressing out about a motor, waiting for it to die. For me, it's a no brainer. Looks, size, and handling of the FD, but power, reliability, and mileage of a corvette.

FDFDFD

how's the handling of the FD's with LS swaps? I imagine it would be a little different than having the rotary in there. Anyone?

KaoticFdR1

I haven't noticed any difference...considering the car still weighs the same and the weight distribution hasn't changed.

FDFDFD

It is much more reliable, correct?
