Rotogod

hmmmmm not my point......but if you have to justify it that way.

I was refering to rotary vs. piston.

Lets see how many types of engines are there for automobiles.

Piston
Geesh what Billions upon Billions

Rotary
10s of thousands

Just because you drop a piston into what would normally be a rotary doesnt make it exotic.....

it makes it a piston based engine like every other one on the road.

So you have managed to take a unique car and make it plain.

So an exotic fast car with some issues to a reliable fast plain car.

its all about preferance


I like to be a little exotic

Damn I was not debating reliablity.

If I wanted reliable I wouldnt buy a sports car and I sure as hell wouldnt crank more hps out of it.

I want to be different

I want to turn heads

I want speed

Believe me if I had more than one I would have one with a v8 and one with rotary. Well to think about it I would have one semi stock and one three rotor

BUT it seems you take part of what I am talking about and take it down a differnet path and not staying on my subject.

Want to impress me do something that NOONE has done before. Come up with some new form of power plant for the car and prove that it can work.


Maybe not as good as the old one but without change everything is static

A static world sucks

Rotary is progressive thinking.

Piston is static

Dude, tbielobockie is nothing more than a useless board troll. He has nothing useful to contribute to our Rotary Forum and enjoys harassing people. Just ignore him, it's easy.

According to the information I've read, FISA's rule change that eliminated rotary engines from competition starting in 1992 was made in 1990, the year before Mazda's 24 hours of LeMans win.

Rotogod

Think how long it took to "perfect" the piston engine

give the rotary time and see what happens

Mazda feels strong enough to drop one into the RX-8

Mayde some improvements to the concept and took another shot


But I am sure that you would rather go with what works

remydrm

If a chevy is what u wanted y did u buy a mazda in the first place.... makes no sense. the corvette is an awesome car all together and would have been a great choice. Come on fellas lets keep the 7s rotary!!!!

then again thats just me and mine only runs for about 4 months out of the year.

Can anyone tell my their experiences with putting in the LS1? I'm a do-it-yourself person and want to go at it myself as much as possible. I'd prefer it in PM instead of having to root through all the bashing to find it...

jimlab

Your assumptions about the sequence of events is flawed...

It should be:
1. Duped into buying an RX-7 by styling and quickness
2. Gained first hand knowledge of the rotary engine's inherent reliability issues
3. Implemented solution to keep styling and improve quickness without the headache

Not:
1. Woke up one morning on the wrong side of the bed
2. Plotted to infuriate the natives by planting a V8 between an RX-7's frame rails
3. Mission achieved, the tribe is in turmoil over the defilment of their god

Both run stock F body exhaust manifolds. The NA TII puts out 320 at the wheels, and is totally stock. The procharged car puts 485 to the ground @7psi. I havent had the procharged car to the track, but the TII does 12.7@ 113 on street Kuhmo tires with a 2.2 60ft time.

FastX7

That's basically how it happened to me. My rotary obsession started with a T2. I sold that to "graduate" to an FD. I had motor problems with both, T2 = intake, downpipe, catback and the FD = downpipe, reliability mods. I had the FD rebuilt and it's been one problem after another. Hence my decision to diligently research the LS1 swap.

[B] We will get together and do the thing. Although it wont be in front of a crowd , as I know the last thing that anybody needs is a ticket. It seems that he is actually upgrading his fuel system at this time to support more HP, andmy car was very badly hail damaged (6k worth of damage) and is being repainted. It will happen and you people will be the first to know what happens. I think that I probably out of anybody in the world am the best person to "spout off" about the differences between these engines, since I own 3 of them, dont you think? I dont want to intrude on your turf I was just responding to the topic.

jimlab

At what rpm? And the peak torque was? Or are these numbers just "Kentucky windage" and neither car has actually seen a dyno yet?

cdk 4219

The TII is pretty easy, as there isnt any rack and pinion modifications, and the rear diff is already held by the rear subframe. The speedo is one of the most challenging parts, as it has to be converted from PPM to cable. The car seems to have been designed around the LS1. The FD is a different story, the major hurdle is the rack, which needs to be lowered around 9/16 ths of an inch or so. There is also the Power Plant Frame, which holds the front of the diff in place which needs to be addressed. The FC was definately easier and less costly than the FD. I am partial to the FC, because the parts are plentiful(not that it breaks , but if it does it is less money) and it seems to get more street action, I guess because the FD was a faster car out of the factory, and responds to upgrading the HP output. For those interested most questions can be asked at the V8 rx7 forum on torquecentral.

Jim-



You said it. Simple problem solving....

Maybe once the new rotary comes out there will more *for* having that rotary. I agree with the fact that the rotary hasn't had the development the piston engine has and it may prove to be worthy.

But that is in the future....

I dont have the sheets in front of me, although they were on a dyno. The TII was surprising, since the engine was factory rated at 305.

Scrapiron7

Can a moderator make a different section for this V8 Conversion stuff so the rest of us don't have to sift through it on a weekly basis??

Jason93RX7R1

That would be great. I know many people are interested in this swap but have no good source, in this forum at least, to learn about it. There is much religion here towards the rotary. Which is good and fine, but these swaps still support the car as a Mazda in its quest for speed I think it belongs at least on the RX7 forum and not elsewhere on a Chevy forum, don't you guys think?

Ryan? Moderators? Can this happen?

Car lovers are car lovers guys! Don't forget that!

There is already a V8-RX7 forum on torquecentral.com

I think that the new rotary will be a durable engine. The older non turbo rotaries are durable engines that seem to last quite a while. I hope they train the technicians for the new renesis, instead of the 13brew training (non existant) Just as rotary enthusiasts have thought of turboing the engine I have visions of LS1, although if the engine is reliable there is no sense in messing up a good thing.

LOL, thanks for the laugh Jim

Jason93RX7R1

Yes, I know of that forum. I was requesting having a source for this kind information here on the RX7 forum.

CDK, I agree 100% that the new rotary will probably be much more reliable, and personally I think is going to be a monster powermaker once the tuners start fiddling with boost on that engine.

Here is the new forum many people have requested. Please remember, tread lightly and without wars.

Jason93RX7R1

Excellent.

To the current V8 or other conversion guys, can you post your info on the thread in there:

https://www.rx7club.com/forum/showth...hreadid=181586

Would like to get a tally of progress on some of these projects as the info gets lost in the other tech stuff.

Tony, I know you are close, and will be doing some extensive tests, weight, etc etc. Would like to get those in there and see the numbers!!!

In the same vein of reasoning, I would say Porsche 911's, from the recent water cooled 911s to the 959 are engineering stupidities too.

Porsche 911 in general: who in their right mind would put the engine behind the rear wheel axles?

Porsche 959: who in their right mind would put this idiotic sequential twin turbo system in an engine mounted behind the rear wheels?

Yet people love these cars for their idiosyncrasies. So it is the same for the FD and its stupid sequential turbo system.

If reliability and torque were so important , people would be transplanting a Detroit Diesel with 250 hp and 500 ft-lb of torque into the FD!!!
