If you do not upgrade, a new stock type part with a higher pressure cap would be far better than an old partially clogged up part.

I think non-AC equiped Sentra SE-Rs also had a smaller WP pulley as stock.
The GTiR rad isn't nearly as big as a Koyo. It's also no longer available. The Nismo cap is also good for another pound or two of pressure over the Z32 cap. I'd have to look when I get home (I have both caps there).

There is only one stock pulley for all B13's with SR's.
