I need an sr20 water pump pulley and since finding just that pulley seems impossible, I was thinking about picking up a lightweight pulley set.

My concern is my timing. I had my timing set by zfever and I couldn't find any info on if changing pulleys will throw off my timing? By taking off the crank pulley will that mess with it?

Side info, engine is not in the car, its being built in my garage.
I know this is a NOOB question but I'd rather ask a stupid question that will get answered than risk anything.

 

No, the crank pulley only goes on in one position and the accessory belts/pulleys have nothing to do with your timing.

 

just dont drop the half moon in oil pan

 

you can change you're pulleys until you are blue in the face, it won't effect your timing.

the only thing that it might do is if you have a smaller crank pulley, it could make it more difficult set/adjust your timing next time it needs to be done. but beyond that, you're good

 

Just what I was looking for thank you sirs
