Alright, I'm considering buying a carbed s4 engine for my 85 GS to swap in because I need more power. And I know some basic things i will need:
-SE oil Pan
-New oil cooler
-Front cover (I'll just use the one from my 12a if that works)
-Fuel Pump

But what else do I need? How will the transmission mount, and will I need some kind of crazy driveshaft? Please just tell me everything I could possibly need.

I thought you should have a front mount oil cooler. Why do you need a new one?

PercentSevenC

You need a Racing Beat front mount bar OR a GSL-SE crossmember OR you have to slot the holes in your 12A front mount bar and/or crossmember a total of 20mm. You also need to mod your fan shroud if you're going to use a clutch fan.

You don't need to touch your transmission mount or driveshaft.

All of the above, plus if you use the 12A front cover, you'll also have to use the 12A oil metering pump. It outputs more oil than the S4 one, but only though 2 lines, the S4 OMP has 4 that go to the intake manifold and rotor housing. I'd say run the 2 to the rotor housings. I don't have experience with that, but it makes sense to put the oil directly to the rotors.

....or you can just premix.

And for the 1500th time the same information is having to be posted? It's been covered and covered and covered and covered and covered and covered and covered.

This is really beyond irritating!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!

Depending on the carb and fuel pump, you will probably need a fuel pressure regulator. As far as the MOP lines, I prefer them going into the carb or intake. Those points provide better overall lubrication. I've torn down FC engines and can see where the MOP oil enters and does most of it's lubing. There's a nice unworn stripe on the housing beginning at the MOP hole.

DEFINITELY searched a **** ton for this, it was nowhere to be found on here. Everyone just discusses T2 swaps, which are different, And if this bothers you so much why don't we have a sticky of the things you need.
