Can anyone tell me a good reason why all new car engines shouldn't be GM's Gen 4 small block V8? I think the next RX7 should be equiped with such an engine. I am convinced it is the best powerplant ever produced. How would one not make my RX7 better in everyway? How can the rotary possibly compete with such a power plant. I just want my car to go, quickly, were I want it to. To instantaniously appear there would be more my style, but I can't seem to make it do that. If I build a car from scratch and design it to be neutral and ballanced and fun, how can I pass up the Gen 4 for a rotary? I want your flames. Come to me. Surround me. Tell me I have a dick in my mouth. show me pics of your glory holes. I am gonna post all this on RX7club.com just to see what they say. I hope Yamamoto himself comes on to tell me why.

word. I'm doen with the rotary engine. I sold my 3rd gen and am in the middle of converting my t2 to ford power.

It has such an inefficient combustion chamber...I mean...dang its so big...and how much power can I transfer to an imput shaft with 1/2 inch of effective stroke? If V8 does not have problems with bearing destruction of any kind and is small and light enough to be put in a small car, why not have that. how can there be anything better than perhaps an all aluminum, wide angle V10 that has as few parts as possible, IE: valve train stuff, say, I don't know maybe 5 Liters, what ever is needed to get me down the road, DOHC with 40 valves, cam directly activates on shims over bucket on valves.....what is the point if it works and produces more power easier to do more work....??

Ive owned many rx7's....

LS1> owns all mass production motors, thanks.

Word, I'm done with rotaries. Nothing but 8's and 6's from here on out.

Why do people keep using unnatural, inefficient V shaped engines?

Its been known for years that inline engines are naturally balanced, with the exception of 4 cylinders, torquier and generally better. And yet they still make V engines with gobs of heavy balancers and counter-rotating shafts.

I say all new cars should be a high displacement DOHC I-8. A modern version of the one my grandfather's Pontiac had.

Fixed :bigthumb:

A rotary is definitely a more fun engine but I think I'll probably go with a v8 next time around. oh and I've owned many LS1s so that doesn't mean anything.

Actually, I think all cars should have engines like the old WWII propeller engines, with a ring of pistons. No V's, no Inline's, no horizontally opposed... 6 pistons, spaced 60 degrees apart from each other, mounted flat. That would be hot shit.

Ha my boosted 302 costs a fraction of the setup in my rotary setup cost me.

Rotaries are only as cheap as your fabbing skills.

If you're good enough to fab a PP system, you're set. Otherwise get a piston engine.

Different ball game. you're still talking about thousands and thousands of dollars.


I'm not trying to call a 20B FD cheap and fun. I'm calling FBs and FCs Cheap, fun cars. There's no denying that they are.

Rotary motors are fun to play with but if I wanted dependable INSTANT power I would not hesitate to go V8. As of right now Im having fun building small displacement engines and boosting them, I'll have another 8 one of these days when I get bored.

i think it's funny how rotary boys turned pistonheads try to get us diehard rotorfreaks pissed off. aint gonna happen.. it's simple, you either like it or you don't. are you gonna be conventional, or are you going to try, and stick with, something relatively new?

technology, in a different way of making power, will only go further if certain people are willing to push ahead into another realm of power and efficiency.. till then, i'll stick with my 2 and 3 rotors, thank you.

everytime i see a heavily modified big block in some old muscle car or -7-, i think, 'how plain?'

I think "How efficient". Especially since you can't prove that my little 7 with an LS1 (read all Alu) wouldn't weigh less than your average optioned out turbo II. Its not that I am a rotar head turned piston, I don't care what type of engine I have in my car, its just a propulsion system to me. I want the smallest, lightest, easiest, most reliable way to make lots of HP and torque. That is not the rotary. You can have all the power pulses in the world, which you don't but I'll humor you and say you do, but you can't make up for that 3.5"~4" stroke. Its not gonna happen. The Mazda add says "non of these cars have ever dropped a valve, broken a ring, or something," I'll have to say, non of the piston engines I've ever driven have done any of that either, and we don't endurence race to work. If we did, it would be different, but at 200,000 miles, your average new motor with regular oil changes still has a visible cross hatch on the cylinder sleaves. why re-invent the wheel, what we got works so damn well.

it's about damn time! give the rotary more R&D. as much as the piston had. like i said in my last post, a subject will only improve if there are diehards out there WILLING to push the envelope and go farther. no one is arguing the fact that the piston is/isn't more efficient, you're talking to yourself as far as that goes.

i don't think we're on the same page... we're talking propulsion systems cowboy, it's not as simple as the wheel.

The only problem with the "why re-invent the wheel" argument is that we'd still have horses.

"Shit, they get us from point A to B. Why fuck with the system?"

I think the big problem with both the piston and Wankel rotary engines is the reciprocating nature. What is needed is a true rotary engine.

Whats plain about popping the hood of an rx7 and seeing a boinger? Tehre is nothing more conventional than the thousands and thousands of pos na rx7s out there.

Your speculating. R&D? If anything, I think the renesis is a step backwards in terms of high performance rotary engines.

Why do you say that?

Why do you say that?

Umm its a 6 port which sucks. The exhaust ports are in the wrong housings and have a 120* bend in them now.

Do they make more power?

Do they make more power?

Than what? older 6 ports?

Than what? older 6 ports?


EXACTLY. I too think it is a step back. I don't think you can improve the design. That exhaust port is crap. It can't flow like that and has a huge flat wall in it. The fuel injection setup on it is more advanced. ooooooh. I just don't see the advantage in it anymore. I have learned too much. crap. I used to think the rotary was the end all engine. Now I just think it makes one hell of a bad ass formula atlantic motor or something like that. Very small cars that can have really low center of gravity will work well for them.

We're on the same page. I realised last year that I'm in love with the chassis, not the motor.

well said. I just re-read an article in Super Rod magazine, they had a stock LS1 that put down 417 hp on an engine dyno with equal length tube headers with mufflers and ps or ac. With Comp cams XR 275HR cam and RPM valve train kit, it made 470 HP @ 6100. Touch that with a rotary that makes 449 ft/lbs @ 4900 rpms and carries over 400 ft/lbs from below 3,000rpm. All this in a motor that is 26 inches tall and weights 490 lbs fully dressed. A fully dressed 13B REW weighs around 350 lbs from some unreliable source. I read at the same site that the renesis weighs like 255 lbs. So yeah it weighs less. I still want that warped sound made by the altered firing order.

Umm its a 6 port which sucks. The exhaust ports are in the wrong housings and have a 120* bend in them now.


Bah!

I challenge you to build an NA four port 13B that make as much power with as flat of torque curve that is just as streetable as an RX8.

It is not a step backward if it is more efficiant and making more power. you're just a nay sayer.


I'm shure whoever enginered the renisis was not a fucking fool and probably spent more time thinking about it than you have.

Probably so but it still don't make 420 HP and sound like this...

Oh if I was serious about making big power I'd go V8 for shure.
It just seems alot of you are really reaching for shit to talk on rotarys.

Live and let live. You've just moved on that's all. No sense in wasting your breath trying to prove the futility of a certain motor. Some of us are still having fun.

double :werd:

like i said, you guys are arguing to yourselves and it's FUNNY. i'm having TONS more fun than i ever would with a piston/valve. there's more than one way to go about doing things in the autoworld.

james, i'm glad you're happy with having 420hp. you're having fun right? i'm also glad you like the sound of it.

Your speculating. R&D? If anything, I think the renesis is a step backwards in terms of high performance rotary engines.

and I'M the one speculating?

the things people say, i swear...

I'm not ignorant enough to even own a rotary without a turbocharger hanging off it. Let alone try to build one.

Hows that? You don't laugh when you see kids running aroundf in their 1980 somthing shitbox rx7s making vroom vroom noises. Lets wrap the thing out to 8 grand so we can pass this minivan.

That's the stupidest thing I've ever read on here.

Ignorant?/?/? That's the most ignorant thing you're ever said.

Being too ignorant to do anything besides bitch hardley puts you in the position to critique mazdas engeniering aproach on anything.

Face the facts man. The renesis is a dissapointment. Poor fuel economy, low power. Laughable torque.

Face the facts man. The renesis is a dissapointment.


Being better in every way than all of it's predecesors is not a dissapointment.



Rotary's do not make as much torque as V8's. It's like you just found that out and you're pissed off because nobody ever told you.

Ohh rotaries can make pretty impressive torque- with a turbocharger. NA 6 port motors don't even exist to me. There is almost no advantage.

There is almost no advantage.



And there is no dissadvantage. You'll get the same sesult boosting a six port as you will a four port. I reccon you're just buying into the six ports suck school of thought because you've heared other people say it. people tend to like whatever they have because it makes them feel better about themselves. Kinda like what you're doing with your V8. But you'll never hear someone with a six port motor say it sucks.

If you have no appreciation for a well tuned naturally asperated motor that's up to you. Turbo a rennisis and I'm shure you'd like it. Not everything came with turbos from the factory you know. Not even your small block ford.

I have seen porting first hand from most of the larger builders on both 6 and 4 port motors. Tell me there is no advantage to a 4 port when going for real power.

Both can be bridge ported. That levels the playing field.

If you're talking street ports. the six will wind up slightly smaller, so run a couple more psi of boost to make up for it. Unless off course you're talking about NA motors, but I know you wouldn't back step like that.

Does driveability matter to you? you seem like a dyno queen kinda guy. PP them both and see what happens.


There is always an advantage to somthing else you could have done when going for serious power. When you're done with your project are you going to be kicking yourself for not stroking it to a 347? Or starting with an LS1? You could have had more power. Or you could be happy with what you've made like many rotary owners are.

Sence the ford motor your using is inferior to the LS1. does that mean you are using the six port of v8's and essentially wasting your time? You are never going to have the most powerfull car in the world.

No I'm for fun well balanced engines. A peaky rotary is not my defenition of balanced. The motor I have is a built mexican. We'll be able to approach 800hp on this motor with the boost elevated, more than enough. As far as going with the ford; I chose the ford because I've been dicking with them for as long as I have rotaries. Cost was also a factor. I'm not about to dump 6-7k into a motor alone for my t2 that is maybe worth 3 grand.

Do we have a difference of oppinion anymore? I've lost track.

I know you are terying to connect a line between a built 302 with a turbocharger hanging off it to 6-ports of rotary gayness.
