Know a guy that's wanting to piece together a 4 port 13B for his 1st gen. He has a complete 76 engine. Here is what he needs to know.



1)Assuming the rotor housings are shot will -SE housings work OK?

2)With either housings will there be a problem using S5 NA rotors? I seem to remember hearing newer rotors didn't like the older housings for some reason.

1) yep, -SE housings are updated 74-78 housings



2) new rotors go into the old housings better than old rotors go into the newer housings

Sweet. By better do you mean it's Ok to use them? https://www.nopistons.com/forums/pub...IR#>/smile.png

yes.

i built a gsl-se engine with an 89 rotating assembly (rotors, gears, flywheel) and it ran, well runs great, when the owners not ******* up the ignition system
