Good idea in theory, except for the many LS1 swaps in FD's and FC's which show no weight gain and actually a slightly better weight distribution...

 

im on here because i currently drive an rx8 and the people here are great, not because the rotary engine is gods gift to earth.

the rx8 is cool but itslacking in a bunch of categories and im likely gonna replace it with a better car at some point (there always is a better car...unless you somehow get that new ferrari enzo replacement)...im not gonna leave the site though when that happens.

Btw the 4G63 is a tested and tried power plant and i'd totally swap for it

 

one thing I always point out to the people that say this, is that the v8 swap is a kit design by a performance shop and such it is not stock, if I want I can put the 13b-rew engine on an fd 4.5 to 5 inches more to the rear and 3 inches lower ( i have done this to several cars) imagine what this does to handling at the same time moving the battery to the rear to keep the 50/50.

dont compare non stock cars to stock cars.

The rotary engine out perform the 2.3 dizi engine in the ms6 and ms3 7 years ago, so imagine what a factory turbo 13b resnesis with DI would be today

 

well if we're not comparing non stock cars to tstock cars a factory turbo renesis isnt available either...nor was it conceived as such...the renesis was designed as an NA powerplant, while the 13B was from the ground up a turbo power plant as you more than well know (btw love the work you've done to your rides).

 

thanks for the compliments on my rides, I just think is not really fair to compare a FI engine to a NA engine if we do this then the engine on the mustang is a pice of sh..t because a 3 litter turbo engine from 14 years ago had 20 hp more and todays 2 litter engines are making as much power, and so on.

I think the renesis is one hell of an engine, and it is smaller in fisical size to the 2.3, I would really like to weight a 2.3 with turbo and intercooler.

 

that was actually gonna be my next question...if anyone knows what the DIZI weighs. i know its top heavy with a Top mounted IC but FMICs can help that.

 

FMIC also throws the weight way to the front of the car...no matter where you put it, it is extra baggage.

 

feras i dont believe its the best engine to ever come along either. im justr saying you shouldnt act so suprised that on a forum about arotary powered cars you would find rotary supporters/ fans. and disregarding/belittling their opinions because of that is ridiculous

 

Almost as ridiculous as disregarding/belittling the opinions of people who would be open to something else?

 

When Mazda announced the return of the rotary to the US years ago I was very excited because I loved my RX-7, but wanted something newer (with a warranty). Then I saw the RX-Evolve concept and my heart sank. I HATED the way that car looked. I knew that if the RX-8 was released looking like the either one of the two concepts before it I would not be buying it.

A big selling point to me regarding the 8 is the look of it. It really is a beautiful car. Another big selling point is performance. This car handles like it runs on rails. The power curve is smooth, and it's pretty quick despite not having gobs of torque. I really do love this car.

However, had you asked me two weeks ago about my 8 I would have cursed its name and Mazda's too. Difference? It's 65 degrees in PA today. It's been under 80 degrees for the past week. This car does not like the heat and it shows. I've mentioned the sweet spot here before. It seems that under 75 degrees, this car runs flawlessly. It still handles well, but in the extreme heat of summer it does not run well at all (at least for me).

I thought I bought this car because of the unique-ness of its engine. But in reality, I bought it because of what I remember best from my RX-7 - handling. Mazda makes cars that handle really well. The rotary makes little difference to me.

Sure it's cool to be different, but if Mazda sold an MX-8 that had the same great looks and the excellent handling of the RX-8 along with better gas mileage and power, I'd trade-up in a heartbeat.

 

The bottom line is this; if you are wanting to put something else other than a rotary in the RX8 go for it, that's your taste, and that is fine I think that any engine modifications, and swapping is interesting. But, you have to expect to be flamed or critized for not sticking with the rotary. For me I would never put anything other than a rotary in my car or any RX car for that matter. The whole point of the RX is that it contains a rotary engine, to the die hard "rotor-heads" this is key, so you can understand why you would be "attacked" on a forum like this.

 

Hey devious. Great post buddy. However, I think you posted in the wrong thread. This thread isn't about engine swaps, it's about a hypothetical situation in which mazda offered, from factory, two engine choices (piston, rotary) as they have done in the past.

It was pretty clear to me the point of the thread. The OP even went so far as to remove the R from the piston version so that people like you wouldn't oh so cleverly point out "R means rotary". Good catch though.

I guess maybe it's too much to ask for rotary lovers to just say, "I'd pick the rotary" maybe add in for "XXX" reasons instead of failing to read, or comprehend, the original post and jsut going off on rotary purity blah blah.

I guess the bottom line is this: you might work harder on your reading comprehension.

 

so i guess its ok to compare stock engines to imaginary ones... interesting

 

I think that there are enough piston engines out there that could maintain a lot of the RX-8's feel. I don't think the choice is a binary Mustang vs RX-8.

Say you did put the 2.3L into the car. Now, you just may have shifted the weight distro and got a 55%/45% car or something like that. But you didn't change the direct transmission feel, the powerplant frame, the carbon fiber driveshaft, the steering feel or most of the suspension. I think that much of the "feel" would remain.

 

not really, but the 13b-rew in the 1999-2002 rx-7 out perform the ms6 and the ms3 engine

I think a more fair question is if you would replace the renesis for the engine on the s2000?

they are about the same size and waight and are NA

 

some of us where aswering to people that sujested ls1 swaps and v6 swaps

 

Cool, that's still not the bottom line of this thread.

 

the bottom line is that 50 out of 70 people prefer the rotary, even as a less powerfull engine

 

What's your point? Few if any threads stay on the pure topic that was originally posted. Everything has been enough within line.

 

That surprises you?

 

I vote Renesis

 

the bottom line in my mind is based on the MS3 and MS6 performance, we could have a mid 13 sec car that gets 30mpg and retains the 50/50 weight balance and handling for no additional money and still have a 7k redline and with less maintenance and more aftermarket potential.

 

lol...

 

I'll pay more to have a renesis turbo! and that is way theres a rotary after all because a group of people love the engine and are willing to pay more for it

 

Maybe it's that high within the RX-8 community. I have a feeling if you posted this poll elsewhere most people would prefer a turbo 4.

I haven't voted because I have mixed feelings on the issue. If it were a 4G63 or another well established turbo 4 I might be swayed. In short, I just don't trust Mazda with turbo charged engines and I like the fact that there is still a rotary powered car even if I probably won't ever own it.
