Hey guys, I own a 1st gen 79' RX7 and I love this car but I do want to swap in a better engine on the 13b area, I'm leaning towards a 13btt swap but I'm not sure on what I'm going to need to do a clean swap for it. Any information would be great, even recommendations on a different engine if it's easier. I just like my toys and I finally have the opportunity to build mine I'm just on a limited budget. Like I said, any help would be great! Thanks!

 

Use your same front cover, a GSL-SE oil Pan and a 86-92 CAS. Those are the first parts needed for your swap.
