Well new heads is a given at this point. I of course would get new heads to match if I did that.
What I'm most pissed about is I just today finally got the rest of the material for making my header. Took nearly a month. I will never order from Great Planes again!
Anyway, I ordered all my tube in 1 3/8" OD which makes it not quite 1.3" ID. Pretty small for anything much bigger than a 1600. Shipping was too high to bother sending back too.

I would stay on your turbo path as much as is practical until you get it finalized and keep focused. Then build a million dollar motor that will take a year to finish. :shock: I would prefer to rebuild used heads because the high production replacement heads have a bad reputation with hardware like seats and machining. You really have to have new heads rebuilt. :lol: If not I would buy a decent pair of new stock replacement heads just for the 1600 and hope for the best. You could resell them in the future if you go bigger.

So I just checked my #3 cylinder ring gap for grins.
Top ring:. 076"
Bottom:.. 042"
End play is. 0055"
Those sound like uncompressed ring gaps. You need to measure them when in the cylinder. End play looks great.

They were in the cylinder, but I realized I didn't push them down very far. When I checked the top ring I just turned the piston upside down and pushed it in to where the second ring was. I just did it again and pushed it down further but it was still. 043, didn't do the second ring again.

Cam profile has a lot to do with that I think.

It's a stocker. All I did was add HD single springs and chromoly pushrods.

I put all my parts in the steam cleaner today so I can look things over better. Might even have the correct hone at work to do it right. We even have the fancy machine to do it with! But I don't know about just getting new rings. A set of pistons & cylinders is only like $180 so I don't know if it's worth the gamble.
I have no idea how that rocker screw came so far out!
Yes, but does $180 get you Mahles or cheap rubbish. Because if what you have is Mahles and they're ok, a clean and a set of good rings will be better than brand new cheap junk. Lots of us are using 85.5mm Mahles and they're very forgiving for turbos even though they're not forged. ;)

Maybe just do cylinders and rings. I have a feeling clone is running AA hyper pistons and not really having issues. I'd love to see how much taper there is in your cylinders. Gotta be a ton with those ring gaps and the difference from just sliding it down the cylinder a little deeper.

I'm going to bring them to work tomorrow for the guy to measure. I'm curious too. He said we don't have a fixture to hold them down for honing. Says he can make something though.

If they're tapered ,it only does it right at the top last part of the stroke so it's apparent by sliding your finger over it.

I didn't feel a ridge when I drug my nail across it.

Some don't wear a ridge but they always taper. All you have to do is measure the ring gap at the bottom of the stroke and then about 1/4-1/2 inch from where the top ring stops at TDC towards the bottom.
