WTB: NB Alternator Pulley
 
Adding an ATI Damper and 12 tooth trigger wheel soon and forgot I need the ribbed belt pulley instead of the NA V-belt pulley.

If you've got one laying around, let me know.

You need a 94-97 alternator for the bigger shaft, so...yeah.

I've got a msm alternator and pulley, but it won't bolt on to a 90-93

Weird. My car originally had a ribbed pulley on my replacement alternator. I'll have to see what my alternator shop can come up with.

We had the same issue with Laz's MSM engine, and Oregonmon's VVT.

We haven't measured Laz's, but we're pretty sure we just bolted a ribbed pulley to a 1.6 replacement. We had to shave the front housing down, but that's about it.

With Oregonmon's we had to buy a NA 1.8 replacement, which obviously came with a ribbed pulley.

So I'm pretty sure there's some "aftermarket" brand of 1.6 alternator floating out there with 1.8 sized shafts.

Thanks for the potential heads up Josh, makes me glad I didn't get an aftermarket core. It's an OEM 95 core.

Oh, you'll be fine then.

I have a ribbed pulley for you then.
