alright guys this is for you techs out there. i would like to know what between all the sr20's is actually a compatible internally, headbolts aren't for example, so:

rocker stopper's?
valve springs?
camshafts?
camgears?
crankshaft?
pistons?
rods?
are heads interchangeable?
is the bottom end interchangeable?
can i put a gtir head on a se-r bottom end?
can i use se-r internals on a gtir longblock?
etc.....
i hope you guys know enough to help me and others out.
i think if i can get enough facts in this thread will all learn something to better our motor building in the future.


i dont have a specific plan b/c i have already built my car and was just wondering if there are other availabilities for me in the future.

thank you and i be seeing you in my rear view mirror.
