Difference between 84 and 86 housings
Has anyone here built a 13b using one 1984/5 housing and one second gen housing?
I know there is a metal diffuser (which I will remove) in the exhaust port of the second gen housing. Is there anything else different?
Mazdatrix has a different part number for the different years of the coolant seals.
So basically I wanted to built a SE motor with one second gen housing, the rest is all se components.
Thank you

Nope. All 1st gen engines have the grooves in the rotor housings,including GSL-SE 13B's and the 70's engines.All 2nd gen engines all have the grooves in the iron housings,as do the 3rd gens.Not sure if they changed back for the Renesis.
There was also a slight change in the shape of the rotor housing for 2nd gens.This is supposed to prevent 1st gen rotors from working in the 2nd gen housings,(and vice-verse)but this is widely debated and many say they've succesfully done it even though some builders say you shouldnt.
