#225278 if you are trying to use A1/B1 water pump that on a Stock b20 then NO .. well i suppose you could.. the stock water pump is a vtec water or (GSR/B16) (i think 22teeth?) while the LS is 19teeth or other way around. but everything is yes.

#225279 i wouldn't put a used water pump or thermostat into it even if it is the same..



is your A1 motor obd0 or obd1? pretty sure your gonna have to convert your intake mani, dizzy, and what not to the B20 to make it work. i think they're all OBD2. not 100% on that though...

#225348 Not sure about the water pump on the B20. I was under the assumption they were the same as LS's. However I never confirmed this or checked the books/part numbers.

Also all B20's are OBD2, However Easily converted to OBD1 with your OBD1 Injectors, LS Dizzy (or use Teals DIY to build a obd1 dizzy) and your obd1 d series alternator.

I Agree with Juice, I would only put new parts on my engine. I didn't do that when I did my b20 swap and am now paying the price with a Failing waterpump. If you buy new parts it would make since to get a new P72 GSR Waterpump and Timing Belt. Shouldn't cost much more and will give you the peice of mind for when you over rev your engine that your still good.

#225407 since your are using the z6 harness, go with the obd1 ls distributor.
