I have a extra Y8 head that I don't use ..

Is ther gains by bolting the Y8 head on the z6 block...?

I'm still gonna use the z6 intake manifold...

If ther is gains... what parts am I gonna need 2 change..
time belt?
Water pump?

 

Well I was going to do this swap but decided not to because it cost me more then I had. SO yeah you have to get a new timing belt and it's always best to get new water pump. There isn't really a significant gain by doing this I know that the ports on the Y8 are larger so you get a little more comp. You will gain maybe 1-2hp and 1-3ft torque. Everything of course should bolt on without other things it's just better to get everything replaced on the head. Get new seals and gaskets.


-------------------------I made my decision and I got a D15B instead-------------------

 

what timing belt the y8 or z6?

And yea I had a d15b real nice motor...

 

Belt??...

 

I blew a huge hole in my block a few months back, the engine had around 250k on it. I searched around and bought a block (D16y8 block) and bolted it up to a new D16z6 head.



I think thats what it was? Or maybe they were switched.. Who knows, either way the car feels a little different.. Most likely because the new block and head only have around 94k on them.
