Wanted to buy passenger exhaust manifold

[jaystcb]

Looking for a passenger exhaust manifold. Does anyone have one for sale?

If your desperate, I've seen a China turbo system for 4.3 on Amazon and ebay. "Turbo kit 4.3 V6" is what I typed on amazon.ca Maybe you can get just a manifold instead of the whole thing from these guys.

There are 4.3 Exhaust manifolds on Ebay, a couple people on the facebook group said the fitment was fine. I have yet to buy them myself and test fit them, so take that with a grain of salt. They are $356 on the Ebay post I'm seeing here. I think Erick Tinn on Facebook mentioned a while ago that he had a whole bunch, so you could try contacting him to see if hes still hanging onto some OEM ones.

Bolt it to a loose head and weld it. There is an 'art' to welding cast iron so it won't crack adjacent to the weld, so be sure the guy doing it knows what he's doing. Pre-heating the part prior to welding is an important step in the process. That was my plan for the crack if it had gotten bad enough to worry about.

I use the heat it and cool it in the charcoal briquettes method to weld cast iron.

This is what's called knowing the difference between knowledge and wisdom. DaveP wins again.

Thank you guys for all your help.

So I ended up going on two different forums and a several SyTy Facebook pages. I got a bunch of messages from people that wanted to sell me the whole kit and caboodle for $500 and not just the turbo side manifold. I even contacted sportmachines. And he said he would separate and sell me the turbo side manifold for $500 by itself.
So I ended up doing a little extra research and I reached out to the guy on Facebook that sells the new manifold kits. he said he would sell me just the turbo side. So if anybody else needs a turbo side manifold. I copied the link and here is a picture of his name on eBay so you can contact him.

My neighbor is an industrial heavy equipment welder. He said it is definitely time consuming to do it correctly. Apparently he has done several non syty cast manifolds over the years.
He said the process is
Groove out the crack.
Clamp to a fixture or bolt it to the block.
Heat the cast to glowing red… almost white. weld a small bead with a special rod for cast.
Let cool to worm.
ping the weld worm, then let cool.
Then repeat the process until done. Should take 4 or five welds and a day to do it.
(Going off of memory from a few years ago. So above process might be off a little.)

I gave him my old one a while back. But he hasn’t had the time to repair it yet.
