Think about how much air there is inside a V8, and how little there is inside the rotary. Rotaries are very dense, therefore heavier than their size would suggest. I believe the CG height is probably more academic than actually noticeable. Besides, that's what the sway bars are there for. Tune the suspension to get it balanced. Please don't add ballast.

A cam, pushrods, carb, intake, rocker arms, heads (provided they are aluminum), dizzy, etc. weigh about the same as half of a rotary.
If you ever had to flip a V8 over on an engine stand you would be able to see what I'm getting at

Here's a good rule of thumb. If you think the swap is a horrible idea, that's fine, but don't simply post here saying how stupid you feel a person is for wanting to do it. To each his own.

If weight's your issue, then why do people go ga-ga over GSL-SEs? They have a similar "nose heavy" weight distribution. (Actually GSL-SE's are worse... they are 54/46)
Also don't forget that handling is in the end up to suspension design and tuning. Heck the best-handling car I've ever owned positioned the entire engine mass in front of the front wheels.

I just like to point that issue out to all the newbies who start thinking about the V8 thing. It's a trick better left up to a more seasoned fabricator and builder. I just didn't like having to sit and wait for justice when my UPS-bred wit (and pride...) could have dealt with this ......ina a more fitting manner....close the thread....

The only name I called anybody is "peanut head" and that might not even be an insult... cause in some rare cases you can have a small head yet yield high intelligence.... Oh well... close the thread....

Geez,
I don't get flamed this bad by the British car crowd for talking about dropping a dizzy into a little British roadster. And I think they have more reasons to be upset than the rotary crowd. For example, longer racing heritage, cars no longer produced, company no longer exists...the list goes on.
My 13B sits lower than the straight 4 iron block that it replaces and has 100 hp more. And I set the engine back by 6 inches. This car lighter than any RX7 by at least 1000 lbs. Once I've got it dialed in, I'll take on anyone with 4 wheels unless it's off-road or full contact.
Not all conversions are evil or blasphemous.
I'm also an amature. Learned how to fix the EGI on this board, learned how to operate a MIG this year. So just because I'm ignorant today, doesn't mean I'll be blind forever. I luv this stuff, and I get a lot from it.

Jeez, almost everyone in this thread sound like a bunch of married couples....
It's his car, let him do what he wants. Maybe the Piston engine DOES feel like he says, you can't tell by looking.
I'd say until completely proven, and we get some numbers on G's and Accel, and 1/4 mile and everything, no one can criticize anyone else's car.
This is worse then someone posting a Preaching Christianity and Catholicism on PinkBike.com (mountain bike webpage with forum).... HORRIBLE!!!

But it makes sense for you to poste here because you've got a rotary going into a different chassis. Well, maybe not here in the 1stgen corner, but certainly in this ROTARY Forum. The V8 crap needs its own little corner, so all the members who are into that abberation can go there for useful info. The Forum should have a new category in its Tech and Performance section called "Stupid Idea...", er, uhh..."V8 Conversion Corner". Or go to Ford Forums where other conversions using those engines are done on a regular basis. It' just sad to see them here...

When it comes down to the drivetrain, I still have the same basic questions as the rest of you guys.
