I would think the turbo and inter placement would negate the advantage of 20B placement? Just like LSx hight...both seem to have a trade off with additional weight being added higer up?

Agreed but the point is to address how handling would be affected. How to overcome any disadvantages. Prove that there even is a disadvantage...ETC ETC.
I think many have secretly asked themselves this question. Hell this may even reveal a disadvatage in 20B turbo swaps (regardless how AWSOME they are). Seeking the truth is all or at least a very good solid guestimation.
I want to see some physics! Anyone got the tallent? Cause I suck!

ummm the center mass would be straight down the middle of the engine....
3 rotors and an eshaft
8 pistons and a crank shaft.
either way the major weight is straight down the middle of the engine.
As you can see in the pics. the 20b can get pushed back further in the RX-8 chasis. close to where the 13b sits.

Exactly...
Another point worth mentioning though is the 20B in that picture is not turbo'd. I would think it would need to be turbo'd for it to be a fair compareson...Power for power. By adding the turbo it would add more weight up top due to turbo, piping, intercooler, etc.
I do admit that a 20B NA would have an advantage in placement and balance since no other equipment would be installed up top to increase weight and mess with the center of gravity of whats located in the engine bay in general.

I have another bright idea...Does it have to be an LS motor?
I saw this and drueled but then I saw the price!

$27,000!!! LOL!!
Does anyone know of a powerful, lightweight, and cheap v8 alternative to the LS?

I heard of the Rover v8's the Buicks used to have. Apparently they were like 300lbs fully dressed I think but I haven't noticed how powerful they can get. I also read that they were used in TVR's?
If anyone can provide links that would be great...searching now for more info.

To me power is an after thought...however it would be pointless to perform the swamp unless a significant improvement is experienced.
My goal with this thread was to discuss the affects and the physics of a v8 swap. What Team said is correct though. I just don't want to initiate and be disappointed with the outcome. If the affects to handling are minuscule or nonexistent then this will be the swap for me. Not to mention, to my knowledge, this hasn't been discussed before and it could be a good source of information for others regardless if I do it or not.
On a side note...I keep seeing the phrase..."Just ask a Viper driver...LOL!"...When reading up on the v8 swap threads.

they are not bullet proof by any means and when they let go it usually is a big event.
Rx7 guys with this swap say if they are not under power then the handling is almost like before..
Even when you boost this car it changes all the chassis responses from before.
My point is-- if you are up for the aggravation in doing this--then do it. Bet you wont c/o about the handling afterward.
For me it would be the electronics that would be really hard to do..

Oh I know they aren't bulletproof. I just got done helping my friend get a new motor put in his WS6 and his old boss has gone through multiple motors in both his C5 vettes. They all were far from stock though. Those vettes are close to 1000whp and the WS6 had been through hell before my friend ever got it with full boltons and nitrous probably. If you don't try to push the envelope though, they should last a long time.

I just dont really understand.
whats the point of having a 1K hp car? seriously.
I mean 90% of the ppl who wanna do LS swaps want "better power/tq while increasing Reliability", but in reality, a properly tuned/cared 13B(MSP/REW/RESI/etc) will get ya pretty good streetable power with pretty good reliability, fine, a 13B-REW will probably last 100K or less but hey, its still not bad. not to mention the cost to do a complete swap will not be cheap(most people have a lot of headaches after the swap)
maybe Im weird, but Im not a fan of swapping another engine into another car, Rx-8 or not.

Lets say your goal is 400whp then. The LSx would be more reliable (aka damn near stock), have more tq, and get better gas mileage. That doesn't even consider the fact that parts are more readily available, cheaper, and basically everyone knows how to work on them.

He has two 1k hp cars lol. He should give one to me.

the parts are cheaper, but unless you can do all labor urself, it is going to cost a lot in labor.
as for "better mpg" thing, yea I think so. but how much did you spend to get that better mpg? that amount of money can buy me years of gas.
this is another each to their own topic I guess.

Pulling a perfectly fine renesis and pulling a blown renesis out of warranty are 2 different things. Once the swap becomes a little more commonplace and the kinks are worked out, I bet it becomes contemplatable to go LSx over rebuilding a renesis. Right now it is best left to those with lots of disposable income though.
