Which One LS1 or 13BT???
Easier doesn't always mean better, the best things come from hard work, and effort.
You can get mad all you want but it's true,a ls rx7 is a poor mans vette--the rx7 wouldn't even be here if it weren't for a rotary engine.
Talking about instant response and turbo lag , I mean really u are comparing an 87 cubic inch engine to a 350 cubic inch engine?
A 5th grader can do the simple math and see that 87*4=348 , so put together four 13b rotary engines together and make a comparison that's theoritically arguable.
A 5.2 litre rotary(if it was made), would produce 600-800 HP naturally aspirated easily, and over 1000 with porting, there is already a peripheral ported 6 rotor out there and I'm willing to say it'll make 600+ whp with only 4 litres of displacement.
Even if you compare a 4 rotor to a v8, the 4 rotor still wins.
rotary>pistons

You have no idea what you're talking about. You cannot just say "lul if u ad 4 rotaries togedar itll make da same powa" They are not the same engine, you cannot use that as a comparison. You said a 6 rotor probably makes 600whp with 4 litres, so I'm guessing you forgot about the 26b which made 700hp with 2.6 litres and from what I've read was actually making 900hp but was limited to 700.
I know exactly what I'm talking about, the 26b is a peripheral ported 4 rotor found in the mazda 787b used in 24 hour lemans-actually isn't allowed in anymore because they considered it to to have an unfair advantage over its piston driven competition , comparing a Mazda race engine that has 3 spark plugs per rotor to a normal rotary with 2 per per rotor would be like comparing a ls1 to an engine from Earnhardt jrs car in NASCAR or the corvette race car made by chevy.
Hands down a v8 is for those who need to compensate, a rotary has more potential.

Maybe because we don't want a Vette. They are incredibly ugly and massive. Their interiors are made of diarrhea and you can get a 97-04 5.7 base Vette for around 14-15k with 100,000+ miles. You can buy an RX7 for 2-3,000$ and most likely do the swap complete for under 10k. Not only do you have a better handling car that doesn't have leaf springs, it looks better, it'll be much faster (~2800lbs vs ~3200lbs) and they have the same ******* engine. Rotary purists are some of the worst. My RX7 has not given me any problems but you gotta admit, parts are easier to come by for LS engines, it'll be much more reliable to have 300-400whp on an N/A LS than a heavily modded 13bt. You also get rid of turbo lag and have an awesome daily driver.

Besides I love the look on the corvette owners face when they get walked on the highway

I had i coach that owned an rx7 rotary powered no v8 crap he was nice as he could be. He bought a vette and turned into a know it all ******* who was better than everyone. I hate Corvette owners. And i think the cars are ugly.

I just posted that there's a 2.6L rotary engine with 700-900hp.
These are all estimations, the fact of the matter is 1 rotor> 1 piston , rotaries weigh less and produce a lot of power, sure the don't have "low end" power, but last time I checked racing is done from mid-high rpms, unless you're granny shifting.
I'm not writing an essay here but if you want to go by the 787b numbers it'd make more like 800-1000whp.

I prefer the 13bt. I like to keep the rotary in a rotary car; it defeats the purpose of getting a rotary car with a piston engine inside. Sure it's unique, but you see the LS in every other car from s-chassis to whatever you wanna fit it into.
I like my Japanese cars to stay how it was made from the factory.

I am new here, but I'm not new to car forums. And I'm not new to these kinds of internet arguments.
I had to laugh out loud when I read the post that suggested buying an old 944 Porsche and doing a Chevy swap on that, and leaving the rx's to someone who cares. I read the same thing, but completely opposite on a Porsche forum.
Chevy swaps are cheating, are generic, etc.... Please. Take a motor and put it in a car that it isn't supposed to go in is anything but generic. What I'd love to see is a rotary swapped into a chevy. I've seen rotary engines in vw bugs, motorcycles, airplanes, a datsun 510... But never in a vette. Just cant figure out why.

I'm not sure I would ever put a rotary motor in a vette . Not that it wouldn't be a sight to see but there would have to be a lot of modifications to that motor to have the vehical be efficient at its horsepower level . Remember the weight difference between the 7's and the vette . This is where the LS is useful bc of its torque it produces .
Don't get me wrong , the rotary motor is one of the most efficient if not The most when it comes to horsepower per liter .... It's mind blowing .
It's just a shame that there is far less people that know how to work on the rotary motor compared to piston and this is a good factor to the fact that you don't see large numbers of rotary motor swaps besides in other mazdas and some high power drag cars .

I agree... I was just bring a little sarcastic. I think the draw of the lsx motors is the ease of achieving reliable power. When you can pair that to a small light chassis, it makes people drool. Heck, Carol Shelby built an empire on a v8 engine swap. You may have heard of it, the cobra? I'm just saying i can understand the appeal... Big motor, small car, better handling chassis. Sure, a rotary car can be built to make a thousand horsepower... But there's no replacement for displacement. Do the same amount of tuning to a v8, and you will get a lot of power too.
I like the way either motor sounds. Its like when you ask someone which kid is their favorite. I love them equally, but for much different reasons.

lol. Again, opinion at best. Who cares? Drive what you like and quit hating.

You remind me of the honda fanbois over on honda-tech when I had my Integra and my now S2000s.I appreciate both rotary and piston motors and what they bring to the table but I don't knock on others like a purist would. They both have their pros and cons and that's why people make the choices they do to run what they like.

This is rx7club, not ls1 club, there wasn't a v8 section on here for over a decade--i wonder why.
Sorry but I will never like v8 rx7s, I like old muscle cars but trying to make an import into a hybrid muscle car I will never accept.

RavynX. : not to take sides but you make many good points in your previous replies.
On another note tho , Usually I do not chime in on such controversial threads like this one for some of the obvious reasons ... Keep in mind that when people ask for opinions ... Especially when your asking people to enter an opinion between piston or rotary , some of us gear heads take it personal for some reason I'm unsure of .
Long story short is that when people ask for opinions ... That's exactly what they get back .
There is no "better" engine . It all comes down to what the owner/driver prefers . Keep in mind that personal preference is what makes each of our cars different from everyone else's. no two cars are alike when they have breached the point of being stock .. But that's the beauty of it . How boring would car meets be if everyone had the same engine , rims , seats , ect ?
Some people ask questions "why buy a rx7 if you want a piston motor and there are other cars in its class that came with a piston motor " . Who cares ? Maybe it's because that's what they came across , or maybe they just likes the body style more than it's piston step brother Toyota supra . I would enjoy driving my 7 with either motor in it . At the end of the day it's still a blast to drive and I think that's something we can all agree on

No one is getting mad here. I was explaining things on an even tone. The LS RX7 is not a poor man's vette. You can go pick up a C5 Z06 for about the same price or most likely even less than it would to build a LS1 RX7. This argument is invalid.
This a completely stupid argument. Yes, the two motors are of different displacements. The rotary uses turbos in order to make up for the lack of displacement (and it still still needs tuning to get to the same power and torque numbers) and the two are in completely different classes. We get it, I think you're still trying to convince yourself, quit repeating it.
This is bench-racing at best. "5.2 liter (if it was made)" Seriously? It doesn't exist, no one is going to make it, and if they did the R&D and cost to get it running would be leaps and bounds beyond any other build. You'll be spinning tires everywhere with that power and would make the RX7's handling useless at that point. Argument invalid.

It's funny reading your responses seeing the lack of 'sight' you have, if you will. You're trying to slander the LS1 build and then you go saying LS1s are for people trying to compensate when you're arguing that rotary is for the "true" people. Sounds like you're trying to compensate for something of your own. You remind me of the honda fanbois over on honda-tech when I had my Integra and my now S2000s.
