I was wondering which camshaft would fit a D16A6?

 

A D16A6 camshaft. Maybe you can clarify what it is you're trying to do first?

 

My camshaft is a D16A6 and it's wore out and I was looking for a camshaft that will fit in the head that has more horsepower.
I tried a D17A1 but it wouldn't fit.

 

zex has some good cams

 

If more power is the idea, you can either source a ZC camshaft meant for your style head (arguably you won't really notice a difference with it) OR do as "sr20paisa" suggested and go aftermarket. Alternatively you can send out your existing camshaft to see if it's possible to have it reworked for a different profile to give you more power.

 

If your cam is "wore out" there are other problems in your engine and its time to rebuild it or replace it.
