DAMN THOSE PICS ARE HUGE ! !

yeah those are the early ones... you can tell by the stamped 13B seperate from the MAZDA

don't know what year thou cuz they also came with the "MAZDA" MAZDA like that...think they were the truck motor...

hornbm.......

 

That is a later logo style. Those housings probably came from a GSL-SE, or possibly a Japan-spec 4-port 13B. The "early" 13B motors were only sold in the US from '74-'77. Those are definitely NOT of that vintage.

 

'76-'78 Aspec, or possibly R5 style Jspec. We need pics of the exhaust ports.

GSL-SE housings are quite different.

 

I put them on Ebay:

I'll hazard a guess - definately Japanese domestic, and either RX-5 or very late RX-4. Seem to be in relatively good condition, would build a nice ported runner I'd say. Nice find _b

 

76-78 13-B dont have many left anymore the exhaust sleve is mot there so cant tell if US 0r J-SPEC thoe.
