I have a 79 Mazda rx7 its FULLY stripped and i want to throw a 13b into it. What do i need t do this? I have a 13b 5 spd tranny i need to know if that will bolt up to both 6ports and 4 ports? (its off a 6 port) And i also would like to know any advice about doing this project if any?
Thank you everyonefor you time!

 

try the search it will have swap Idea's in there

and if you cant find them go to google.com and put in rx7 swap or 13b rx7 swap
I would send you my list but I am not to computer savy at this time LOL

 

very true, run a search as this happens a lot. 13b abd 12 trannies all use the same bolt pateern and are interchangable. also what 13b are you putting in? you need more specifics on your project.
