Let me foreword this by saying that I have been on this board for a while now and don't post anything really, just read, but the recent posts on this board are ridiculous...
Where in hell did you come up with that?
What about the 13B-REW, 20B, 12A, 10A. Those are our "closest kins".
I understand that people compare a rotary to a v6 in terms of combustion cycles but there isn't one piston engine in the world that you can say is the "closest kin" to a rotary. Totally different in almost every way possible. They have an intake, some form of combustion happens and they have an exhaust and that is about it. Oh yeah they both run on gasoline. This really is like a bad dream, except i know i am awake and that i am too smart to even be reading this crap, let alone replying.
edit: I suck at typing so i decided to fix that

Before i bought a the rx8 i was looking into the crossfires, and the problem about those cars is there is even less aftermarket suport then there is for the rx8, and anything that is available is very expensive since these use to be running in the benz.(and you have to have money for that) So you might get an initail bump in power which will cost a crap load of money, and then you will have to spend even more on top of that when you realize that isnt enough power.
Is it possible; sure it is. I remember with the spec V when it first came out and everyone said that droping the VQ in it was imposible. Even the guy who first did the swap said it was. If you have the time and money go for it you never know what you are gonna get out of it unless someone tries.
A swap i wouldnt mind seeing would be an sr20det dropped in, but thats just showing my nissan roots.

If you want to do a swap that is different and makes more power, how about a V-10 Audi TDI diesel? You'd have plenty of power and gobs of torque! I'm a diesel fan though.

My gosh, was that so hard? Thank you Teckfall.... and the guys with some constructive advice.... that was all I was looking for.
Most of the posts about this swap are about the sacrilegious nature of this particular swap....American pistons in place of the rotary. I thought I made it clear that I realized that this swap is against all normal rotor-head thinking... it was simply a curiosity of mine to see what others thought about such an en devour...not to get continually get lambasted about the "I can't believe you even thought that" comments. I didn't expect you guys to try to talk me into it, but I certainly think you are a little over the top in your reactions for no good reasons...
And yes I was simply referring to the combustion cycle/power pulse commonality between the V6 and the 2 rotor Wankel....that is all... I should have said 'closest piston kin' gosh! (N. Dynamite)
OK, so getting a reliable, torquey Supercharged V-6 plant with 5000 miles on it for around $2K (I have no idea where the auction will end up, maybe $5K I don't know), with it's limited aftermarket support, transmission incompatibility, mega shoe-horning effort, and anti-christ like posture, would be the last engine swap anyone would do to a poor old RX-8. Got it. Notes taken. Glad to have been your daily anger outlet. Cheers.

Well, to be correct they're German pistons...that is a rebadged, slightly detuned Mercedes AMG engine from the previous gen SLK.
That's the dirty secret about the Crossfire, it is an older generation Mercedes that Chrysler simply rebadged and refitted body work around and called it their "all new" sports car, when it was in fact anything but all new.

wow, it totally is possible to do that, but if you would like to do an engine swap, it would be much easier and wayyy more potential to swap in a 20B or other rotary engine since they are much more alike and doing jobs on them would be easier and cheaper

First, I love the rotary Wankel motor. Second, I am kinda loony in the head.
That being said:
What are your professional thoughts on engine swapping a low mileage 2005 Chrysler Crossfire 3.2 supercharged V-6 into the RX-8. Sacrilege of course, but that aside, how cool would it be to give the RX-8 a 330 HP V-6? A Chrysler V-6 that never got a manual transmission that it deserved? I believe the SRT-6 got pretty good reviews and performance numbers, and still weighed 300 or so pounds more than the more sophisticated RX-8... What can be done to further this V-6 into 350-400 HP range? Would it even fit in the RX-8 bay? Am I completely and utterly off my ******-f'in rocker???

I think you fell off the rocker, with this one.
Just go do a Mazsport turbo upgrade. He has 400HP kits for the RX-8 and that should be plenty for our weight of car, unless you are planning to become a professional drag racer. Pettit has a stage 3 supercharger kit coming out soon and that should be doing ~350HP.
So the choice is pretty clear if your sane. If you are only slightly crazy than maybe a 20B swap. But with 350HP to 400HP kits already out, more kits coming and improvement of present FI kits, and a new Accessport ECU flasher for the RX-8 coming... I think there is no need to do a 20B swap, unless you have some type of obsession or trying to eventually push something crazy like 450HP to 500HP.
Now if you are just certifiably schizophrenic (FUBAR in the brain) than go ahead and proceed with the Crossfire swap. Post pictures of your progress, so that we all can be entertained.
Or... If you love the Crossfire so, how about just buy one and drive it around.

All points taken - I was looking at the Mazsport kits just a few weeks ago... saved all the photos from their web site and from 7stock this past year of the air-water kit and drooled etc... I really like their options, performance expectations, layout and general marketing of the product.
I just thought this would be a neat way to get reliable 300+ HP for maybe not that much cash. In the back of my head I was also hoping I stumbled upon the latest and greatest swap (2JZ swaps are sooo boring anymore) but instead I stumbled into a punji-staked Viet Cong man trap. I oughta know better by now, as the rotary community is tightly knit, and rightfully so...I am sorry if I offended my fellow rotorheads... You have no idea how much **** I get at work from all the NA honda guys, the turbo Evo guys, the giant turbo MR-2 guys, the supra guys, all those up-downers! We got em all. I have RX-8 models all over my desk, a wankel display piece, a wankel key chain to explain the merits of the design... it can be tough, I know. In any case, every now and then one questions his or her existance...
After reading the boards for about a year now, I have somehow gotton the overall feeling that turbo kits lead to more problems that their worth (maybe that is just the Greddy stigma) and that for the Renesis, you have to go ***** out in all the performance areas to get a decent HP gain, which inevetibly leads to serious reliability issues, blown motors, pushing a carefully NA engineered motor passed the point of blah blah blah.... Of course many of you have successfully created happy FI rotaries - I love the non-linear kick of the turboed powerplant just as much as the next guy; but when this bloody, nearly new SC'd V-6 from a bastard child wanna be Benzo-Chyrsler product came up for sale, I thought, well here is a plant that *might* fit with some notching, has German engineered 330 HP all day long, has FI (albeit the linear kind) for the cool factor (if any), and to top it off, I get to show those ding dongs in Detroit (where I am from BTW) what this motor can do hooked up to a clutch and a very slick 6 speed tranny (which it should have been in the first place, by anyone's standards). The RX-8 is a fantastic chassis and road car...... the Crossfire is a somewhat interesting to look at car, ideal for trips to the golf resort. SO, for experiment's sake, what if............And that's when I decided to make this shout out to see if this was pure insanity or not. That is all folks.

But I agree with your suggestions. Buy one of the TC/SC kits, if you have money leftover use it to drop some weight from the car and upgrade the suspension handling.
He'd probably end up spending less money this route and might just get more for it.
Oh the whole piston vs Rotar debate: what powers my car and how it does so is far less important to me than the results. I for one could understand his desire, but new that engine swaps are NOT the place to look for cheap power.

sosonic I think your numbers are a bit wrong. Mazsport is around 330 hp and Petite is hoping to break 300 when there stage iii SC comes out hopefully later this summer.

When you dyno a car, they will give out WHP numbers. But car makers give SAE/crank/brake HP numbers which are higher. I use the crank HP numbers because that is what most people see in magazine comparisons. Also, I only know the Crossfire crank HP numbers and not its actual lower WHP number. So its not fair to compare WHP FI kit numbers with crank HP Crossfire numbers.
