thinking about doing a 2j swap after the rotary blows. Have always been a fan of the supra but i'm in love with the fd chassis. Aside from the cost of having a higher center of gravity (can see the rotary thru the wheels) and ruining the 50/50 weight distro, are there any other things to keep in mind? thanks

 

I would be careful not to underestimate the complexity and cost of doing something like this. You will spend many times more than just the cost of a used engine to have properly running car.

You also objectively ruin the rx7 when you swap a non-rotary into it. (I'm mostly kidding, but I would pause before trying to get another old, vacuum-line-ridden engine to run properly if reliability issues are souring your rotary experience.)

 

The $30,000+ being spent to do it right.

 

 

It's expensive and pointless. Don't do it. That's really all you need to know. If you want to put a jz in something buy an s chassis or a tacoma.

 

Is there are particular reason why you think a 2JZ is a good idea?

From 2nd hand experience, knowing people who have owned these cars, the 2J is a great engine but it's similar to the rotary in the sense that: while the rotary has an exaggerated reputation for being fragile, the 2J has an exaggerated reputation for being indestructible. Let me assure you, in no uncertain terms, is the 2J indestructible. Now, speaking from a weight perspective, if you're worried about handling and but don't care enough to want to swap out the rotary that gives these cars their charm and perfect balance...
Here's a shocker: the 2J, alone, is heavier than a LS3. Yes. That's why people love the LS engines. With the turbo and all the associated weight with additional equipment, that will put even more weight in the nose. And unless you're looking for crazy HP, the LSx will be better at doing almost everything than the 2J, including putting around town, to and from cars and coffee.

If you're really determined to do a swap... It's your car, but you will be judged for turning your FD into a corvette :P
