Is the Air Pump interchangeable?

Anyone know if the air pump from a 13B N/A will work on the 13BT?


(yeah, i know similar question to my earlier post; now that I have only TIIs, just trying to see what n/a parts to keep around and what to give to the local tech school)

Thanks! (as always)

the pump outlet pipe is different and needs to be changed, meaning basically you need a TII smog pump, they are identical in every way except that pipe which on the n/a models aims right at your turbo hot side charge pipe.

Again, my thanks. Should be the last time I bug folks with these goofy questions.

Used for emissions and is required if the catalytic converters are still a part of the exhaust for w/o the air pump the converters would burn up and become useless.
