If a FD has been about fully prepped for a LS swap, is there anything that can be done to allow a 13B-REW back into the engine bay?

 

Sure. But depending on how "prepped" it was, you'll need some major components....engine of course. transmission, radiator, front... and possibly rear cross members, any wiring harnesses, ECU, PPF, transmission braces, possibly rear diff, half-axles, etc. A lot of trouble. A lot of cost.

 

If it’s already prepped for the LS why not continue that path? If you want to retract back to the 13b your almost better off getting a complete car with the engine and all other components intact... Tracking all the missing parts down gets pricey.

IMHO build the LS. If you don’t like it, sell the car, and fund your next FD 13b project. Goodluck

 

This thread title makes me happy

A lot depends on what was done to the specific car, and you'll have to think long and hard about which route you want to go. Best to get a ride in or drive examples of both setups. I've driven a few v8 FDs and it's not for me, although others love it. To each their own

 

Yeah, I'll not jump on it, a RX-7 isn't a RX-7 without a rotary after all. Was referring to a Craigslist parts car that I was contemplating.
