Are OEM ITR valves(exhaust to be exact) any different from the GSR valves?

 

Yes, ITR valves are lighter.

 

I think one of them, either intake or exhaust is the same as gsr, but the other is lighter. Search would probably have some more detailed info on them though.

 

The exhaust valves are the exact same...Onlt the intake valves have the benifit of being lighter. At least that is what the dealership told me.

 

Hmm. Are you contemplating buying some?

 

I believe the the valve stems are a smaller Diameter on the ITR. Look up the part numbers and compare.

 

No, the machine shop i used for a valve job kept refering to my head as a gsr to the guy that was actually doing the work and my invoice says they worked on a "1.8 RSR ACCURA"

 

Would a set of ITR intake valves make any more power in my b16 by replacing the stock b16 Si intake valves?

 

Lighter and more even weight between all of them.
there was something else I read a long time ago, but I forgot what it was

only on the intake side

 

"Bigger valves have their advantages, but are heavier. The Type R's valves were redesigned so as to have a bigger cone area, but still be 12% lighter."

probably a tad since the port stem area is thinner on intake side=more flow in.
