Stuff like oil,air, and fuel filters are they the same between NA efi models and RX models? I know spark plugs are different (gaps), and drive shafts. Clutches? radiators? oil/water pumps? belts? etc... Are most things that are not directly turbo related just the same as NA EFI stuff?
Cheers

Off the top of my head...
Oil – Will depend on what you run now. My guess would be yes oil will be different.
Air filter, Fuel filters, Clutch - Will depend on what you run now, although it should be the same.
Drive Shafts diameter and cup’s can be different (this also includes radius rods – RX 1’s are bigger diameter).
Radiator – Will depend on what you run now, if you do not have a twin core rad then I would suggest 1 for the RX, make it mandatory if your going to be running the air con stuff as well.
Oil and Water pumps should be on the RX engine, from memory they are the same but don’t quote me on that 1 its been a looooong time since I have seen the mpfi NA gear.

oil pumps are the same. well i hope they are;)
i replaced my ea82t one with a n/a pump, and works fine. no problems and looks identical.

And after some though i think that my 82t water pump was replaced with a new na 82 unit.

yeah water pumps the same but engines with ribbed flat instead of v belt have a different deck height from what i've read. Radiator was no different in my 85 rx than standard L series.

after all the engine is the same just forced. I found water pumps are the same,as n/a , just check to ensure you have a deck height of 110mm not 105mm for that is for the flat ribbed belt (ah shoot, I missed an ebay item), oil filter and pump appears oil the same Z493, even an efi head can be drilled and tapped to become a turbo head. Yours may be different though coz it was the AWD 4 speed auto L series.

HaHa thats partly what inspired this thread, I kept seeing ebay items go by unsure if they would work properly on a turbo model as hardly any of the sellers list turbo models and are unlikly to know if you ask them.

yeah, it was a new gas mixer to add to my intending turbo demand list.
oh yeah, the clutch pedal set up is different too
