SO... I lost my crankshaft pulley and turns out the part is discontinued by Honda. Is there any crankshaft pulley that is guaranteed to work?

Heck, I can't even find an aftermarket one specifically made for my car.

 

See below for correct info

 

for 88-91 CRX, the DX Si HF crank pulleys are interchangeable - most 88's and some 89's had a crankshaft with a 22mm diameter front snout - most 89's and all 90 and 91's had a 24mm snout - you would need a pulley for the 24mm snout - the reason they have different part numbers is that the ignition timing for the HF is 4 degrees different from the DX and Si and the marks on the pulley are in a different location due to this - DX and Si is 18 degrees BTDC and the HF is 14 degrees BTDC

 

I stand corrected

jlicrx - Then would the 92-95 CX and 96+ still be a viable option?

 

yes

 

Nice. I'm glad people like yourself are still on here sharing knowledge.

 

So in terms of installation, the 4 degree difference means what exactly?

Thank you for insight by the way!

 

Nothing, it only installs one way. The 4 degrees difference is relative to the ignition timing marks.
