I don't care what it weighs. It's still a boat anchor.

It's a sad day in Canada.... whatever, it's just another project and to each his own. You going to the big Canadian meet with that?

smnc

Hey I say it's your car, and if the V8 makes you happy, then more power to ya,

Personally, I'd never even begin to consider even thinking about the slightest possibilty of ever putting a boinger in my car, but that's me.

Well, I guess I'll get to see it first hand at the BIG meet in June?

Good luck to ya.

Et Tu, Caesar?

I didn't expect this from you Felix.

Are you partial to v8's in rotaries now, or do you really think I will denonate and blow up?

I am curious, because my system will be very similar to AJC13B's, In other words Big time power with reliability.

Also as far as that "Stealth" factor WinnipegGSL states, I think a V8 rumble will take care of that.

I'm using a t-5 tranny.

And the ebay issue. Rotor, you arent the only one that expressed inerest in the engine so I made the decision to put it on ebay.

Its not like I hate rotaries, I just want power and I like the look of the RX-7, trying to get 300HP and lots of torque from a rotary is too expensive for a 16 year old.

I'd bet on a 300hp rotor against the weight of the 8. Aluminium intake etc. would make it a bit lighter but it is still a heavy cast-iron block that would screw the 7's weight distribution standard being pretty close to 50/50....

BLASPHEMY!!!!!!!!!!!!!!!!!!!!!!! Why oh why?!?!? pistons aren't your friend.....
I'm glad you're at least working ona 7, BUT, a Triumph or MG with a rotory would be more welcome than a piston powered rx
sad sad sad......my friend has a 99 ws6 t/a and tries to tell me to drop a v8 in my 1st gen
" it's cheaper, faster,LS1's get good mileage;etc" but it just wouldn't be a 7; You get one BECAUSE of the rotary,not to get rid of it.
Why not go butcher a Z or 924 or something...
Just leave the wankle alone
why?!?!?!?!?

87turbo2

btw....i'm in the process of a tii transplant for my 83;
180 stock
adding 3 1/2" dp and 3" exhaust,no cats, and a fmic
should be enough to keep most v8's @bay;
as far as cost;
$200 for 83 with bad clutch
$100 for 87 TII with bad clutch and lots of body damage
$300 for exhaust from local shop
$65 for really big volvo fmic

50 lbs. lighter in the front means you're still 170 lbs. too heavy up front. It would be just like having a buddy ride on your hood strapped down like a deer. Think you're gonna be quickest on the track or even the street when it comes to the twisties? NOT!! Keep it on a drag race track where a hybrid like this belongs and start posting anything else on this abomination in a Ford Forum where they'll appreciate what you're doing. It should be obvious it isn't here....

Ok first im gonna say that will never NOT be a rotary in anything I drive. I like them But with a AL intake and AL heads. Hes right it isnt much heavier... I got a picture of a chevy in a 88 vert and it was weighed by Derek Biven's Chassis Designs (he builds race car frames and has a digital scale)

The car in the end was only about 62 pounds heavier than the orginal car.

79+80_rx-7

Yeah, but looks like theres ALOT more wieght sitting more forward.. and thats bad.

It means Rotary eXport Attempt number whatever ? Right?

tsk tsk, when good 7's go bad

Correct me if im wrong but that looks to be somewhat of a MAJOR bitch!

Apples and oranges, Mike. The 13B is way heavier than a 12A. I believe the Ford is heavier than a mouse. You're still talking at least 100 lbs. up front even after full aluminum optimization of the 302 unless he goes aluminum block. That is the definition of an anchor. A Catalina 28' sailboat anchor weighs in the neighborhood of 50 lbs, so the Ford is technically correct in being characterized as an anchor in that poor, poor RX-7 that has been bastardized...

damon

I think Im going to that kind of is just sickening



why , God help him see the error of his ways

peejay

Aww jeez...

Okay. The 302 is about the same weight as the 12A. Want proof? The front ride height will be the same after the swap. The front springs are only 100lb/in or so, so every additional 100lb would make the front end 1/2 inch lower. Too bad I didn't know about this sooner or I'd have asked ya to measure the ride height before and after

The weight distribution will still be a hell of a lot better than a GSL-SE (55/45) and TONS better than anything that engine could be found in stock. And, nothing else that engine could otherwise be found in has the looks and handling of an RX-7...

Believe it or not, putting a 302 in a 1st-gen isn't that difficult, so I'm told. Swap the crossmember around 180 degrees, make motor mount adapters, and you're 75% there. The EFI manifold will fit under the hood, the stock headers will clear everything... it actually fits the RX-7 better than it does in any Ford.

There is a lot of disinformation out there based on assumptions... assuming the rotary is light (it's not), assuming the V8 is heavy (it's not, especially a SBF), assuming the V8 is larger externally (it's not, when you factor in the manifolds and stuff).

peejay

A 302 is MUCH lighter than the SBC. We're talking roughly an inch less deck height - that's a lot less mass. Also, Chevys are made out of very cheap iron, and they have a lot of wall thickness to make up for the weakness. (That's why so many SBCs have 4 bolt mains, you need that when you're threading into Play-Doh) Meanwhile, Ford uses much higher nickel content in their iron and they have much less metal in their castings, and they're still very strong. A stock 2-bolt main 302 block is good to about 600hp before the main webs start cracking.

You may not believe it, but that 302 probably weighs the same as the 12A that came out!

Felix Wankel

I'm putting my FB in storage, and when it comes out it will have a GN 3.8L in it. I drove it the other day and realized what a colossal waste of money my carb and exhaust were.

Felix Wankel

Well, I meant to say if, not when.

I'm a car person, not a rotary or V8 person.

Hey peejay, is mike right? rx is rotary export not rotary experimental like i said?

Dyre

Its rotary experiment....
Why would they call it Rotary eXport in Japan?
