Blacktop 20V? It has a different lower drive cog then the other engines do...

I'd get a lower timing belt pulley from another 4AG (16V, or silvertop) and try again...????

I usually get email notifications for PMs.

I used everything from my 16v block. 16v oil pump, 16v lower timing sprocket and 16v crank pulley. So i could us all rwd 16v accessories and tensioner.

You can use the 20v oil pump and tensioner, modifying the rod slightly longer. But i didn't trust the hydro tensioner.

The black top 20v crank pulley, timing sprocket, are a bit thicker.

Im also running a HKS 2.0mm head gasket.

Thats all i can think of right now

Edit: i used a Blacktop 20v block, crank, pistons. Everything else is 16v. Smallport head, tvis delete, rwd intake manifold. Rwd alternator and water pump.
Changes are coming soon, as I have high comp pistons in the shed.
