project. Looking to find parts like a hose kit and intake pipe . will a sr20det hose kit from ebay work? Will regular g20 spark plugs work on this engine and ka24de?
Having a hard time here

Yeah, spark plugs are whatever. Just run the normal stuff.
As far as hoses, you're just talking like radiator hoses and such? If so, the majority of that should work, but you might get some extra turbo related stuff as well.
Intake pipe you could either make yourself, or try using one from a KA (or aftermarket) and massaging it to fit.

Anytime you do an engine swap like this, you're probably going to have to fabricate a little something here and there.
