Which One LS1 or 13BT???
Cheap people shouldn't buy an rx7.
The best things in life come from hard work, not minimal effort, just my opinion.

It's a Mazda... It's intent when built was to be cheaper "reliable" car.... Most people that own rx7's are cheap not all but most. And besides a poor mans vette is still freakin cool. As a posed to the poor mans rx7...

That said putting any ol 350 in an rx7 that are a dime a dozen really isn't doing much, any idiot can drop a v8 in their rx7 and act like they got something special.

I like this guy!!! He's got sense
Ls1 aka 5.7 litre which is a 350 ci v8. A 302 is a ford 5.0 , an ls1 is a Corvette engine.
I'm open minded, I'll put a bigger rotary engine in or a newer one, why would I put anything with pistons in the only car distributed with an engine that doesn't have pistons?
That's the entire reason I like rx7s, because they have a rotary engine, its just so elegant and different, the light body , and great body style are just icing on the cake.

I'm a purist so I would go with rotary. Plus I always factor how would I smog any motor swap because I've already had my fair share of designated track cars I wish I could have driven legal on the streets, but oh no thank you very much EPA/Smog laws.
Well, that's how I lean towards making a decision on what motor swaps I would consider, but as stated before decide what you prefer and not what is trendy or what the so called "scene" dictates.
As long as it's a legit and not some half-assed swap then go for it.

As far as i'm concerned I love my Rotary , But I';ve gotten destroyed by enough LS 7's to know a good thing when i see one .
so power wise LS 7 , if you plan to do some track or auto-x competetivly , then stick with the rotary , ebcause they dont have classes for swapped engines from other manufacturers in those .

If you have the funds to do a LS swap I would do it . Not only will you most likely obtain a higher resale value but the LS can achieve more tourqe an a great deal of hp when simple bolts ons are added . And my opinion is that the LS is more reliable

This is complete anecdotal evidence with lots of variables, but I'll give this story.
I ran my TurboII at an autocross alongside a V8 swapped RX-7. It had a Ford 5.0, coilovers, camber plates, and racing slicks. Lots of torque, grip, everything. My car is stock except eibach progressive springs and RE-01R tires. My car was consistently faster through the course. When I rode in the V8 RX-7, it seemed off balance. It was not composed.
In conclusion, the original engine configuration- with its low mass, low center of gravity, and low polar moment of inertia- has its merits. You can't just compare the overall weight of the motors and call them equal.

If you want an ls buy a corvette, putting one in an rx7 is basically cheating, just my opinion--youre basically overpowering the car, its like playing a video game and putting a code in to do double damage....it doesn't take skill.
Go race a rotary engine with 350 ci of displacement and see what wins, or race a well built rotary.
I'll never respect people that need big engines that talk about torque and displacement, even a v6 is better than a v8, people just want cheap power, if you wanted something that's actually a respectable piston engine with high displacement run a rb25/26 or a 2jz, not this v8 junk.
Also to me a v8 swap reduces the resale price, its not the original engine, and I'd personally never buy one with a v8.

When people say "Why don't you go buy it Vette" it pisses me off.
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.

People like us don't want to buy a Corvette just because of the motor. The Corvette is a heavy car with cheap interior and expensive expendables (brakes, tires, etc) so we would rather swap in LS motor into a RX-7 or Miata to keep the same handling, add power, and keep expendable prices down for the track. Honestly it's a no-brainer unless you prefer to keep the rotary and work on that which is cool as well.
Like I said, if you don't like V8s then fine, that's your thing. Just don't go throwing slander at them with emotional and biased statements.
