So my engine is gonna be a huge conglomerate or parts from other cars.

S4 front cover, OMP, and oil pan, S3 housings, S5 N/A rotating assembly and manifolds, FD (Or RX-8) stationary gears and 3 window bearings, FD corner seals, and the largest oil pump I can find.

I need to find a rebuild kit for this...

Do I need to order each and every little gasket, O-ring, and seal seperately or are there seperate soft seal kits for the short block and induction system and such?

 

Why the S4 front cover? How are you mounting the engine in the bay? If you are using S3 housings, you need SE or 12a irons, neither of which have provisions for engine mounts. You will need the SE front cover and oil pan to front mount the engine.

As for kits, buy a rotor kit the S5 rotors and an engine gasket kit for which ever model of intake you are using. If you are using the S4 front cover, look into the differences between the front cover o-ring and teflon one.

 

Maybe by saying S3 housings he means all of them... rotor housings and irons from a GSL-SE...?

I built a mix and match motor getting all my seals directly from the Mazda dealer. They also sell seperate / indivudal pieces to an entire rebuild kit and would take a return on anything that was in stock and wasn't ordered.

 

The S3 housings Should have mount bolt holes. I saw them on the center Iron, I think. I'll have to look again.

 

The S4's are mounted though the center irons, and the oil pan on the passenger side. This will not work with the 1st gen suspension, iirc. You will need the SE front cover, which also has a 4 port mop like the S4's.
