what parts are interchangable on a 20b and 13b..... i have both a 20b and a 13b out of a gsl-se (6 port) ...i was wanting to maybe change out the front covers so i can bolt the 20b into my first gen easier since the mounts would then be up front VS towards the rear in stock form...also about how much would it run on average to have my 20b rebulit if i provide the rebuild kit, or maybe even just have my irons and housings ported since i can learn to take the actual engine apart and back together my self.....yeah yeah i know its alot of questions but im in japan and plan on doing something with what i have when i get back to the states, i just want to have everything planned out b4 i get back.

 

It's not going to bolt up just by switching front covers...

The GSL-SE came with a 4-port motor.

 

i know its not going to "just" bolt up. theres a lot more that has to go along with it. ive been following someones thread since way back when he posted it on ausrotary.com. his name is 20bna or something. but he did tell me that he switched out his 20b front with a 12aT, so i was just wondering. he also turned his whole cross member around and had to make a whole other bar with mounts up front.. im just brain storming...

 

aaaaaaa, na man i didnt......6 port all the way......

 

oh that guys name is Rotary20b

 

No, it was a 6 port. All fuel injected non turbo peripheral-exhaust 13Bs were six-port.
