Who Puts A 2JZ Into An FD???

Rotaries arent light....not at all. its their compact size that gives them an advantage, they can be pushed further back toward the firewall to achieve that 50/50 weight balance. Adding additional rotors does indeed hinder that balance.....but there are always means of adjusting suspension components to compensate

Actually, a 12a or 13b shortblock is a lot lighter than a V6 or V8. I've moved plenty of them around over the years.

The LS1/T56 is about the same weight as a 13Brew/tranny, and LIGHTER then a 20B/tranny.... the difference in the LS1 is about 30-90lbs depending on accessories still used. At 100lbs heavier thats still only a 3% increase in the cars total weight

The cast iron/AL head engines are around 150 lbs heaver (with a T56) and around 225-250 lbs heavier with an auto (though the rotary is heavier with an auto too, obviously).

A shortblock 13B is a lot lighter and easier to move than a shortblock LS1 - if neither is on a stand of course. I have moved both plenty of times, and both are a lot lighter than a 302 or similar block.
I actually had a stock auto tranny that was in a 20B Cosmo. It's about the same weight as the T56.

Personally, I prefer keeping rotarys in the RX7s, and keeping 2JZs in Toyotas. You can make good reliable power with either motor.
