Recycled exhaust manifold

I attacked my 1.8 manifold with a 4.5 inch grinder and a stick welder.

Nifty
You used to see this stuff all the time, then everybody got baller.

pdexta 05-15-2012 02:29 PM

That's awesome, really impressive work.

miatauser884 05-15-2012 04:04 PM

I need a welder.

Miater 05-15-2012 05:18 PM

Any pics of it mounted to the head? Thats some good welding with an arc welder in such a small space. Bet it was a pain on the insides of the runners, or did you weld them up, and then weld it to the flange?

18psi 05-15-2012 05:40 PM

I agree: that's good stuff.
And if you did a good job welding it, I don't see why it won't hold up for a LONG time.
Too bad our manifolds aren't made like that in the US

The welding was easy enough. I welded the collector up first, then the runners and lastly the slip joints at the flange and collector. I used a small rod (1.6mm2 308 stainless) which is good for getting into tight spots.

(For a crazy but simple solution how about tying a stubby downpipe elbow back into the stock 2 to 1 piping flange and a close on vacuum operated screamer pipe through the hood! As if there isn't enough drama all ready when boost hits...but having to contend with a rocket launch as well!)

It may be a while before it gets mounted as the current set up on my car works well. Possibly a winter project.

How about using a heat riser valve dumping to a screamer pipe? Has any one tried this? It closes with vacuum / opens with boost.

Probably a cabin mounted manual boost controller could be used to ramp the closing time or lock it closed.

Honestly that ^ seems like a better option than the spring flapper in the muffler.

I also have the feeling this manifold will have a deep subbie type growl.

When the 2nd cylinder fires, it takes a longer path than the next #1 cylinder then they meet about together. Then the 3rd cylinder fires takes a longer path than the 4th and again they meet together.

Cool work. When I do fab work it ends up ugly or nonfunctional.

Pitlab77 06-04-2012 09:26 PM

very cool

Hideously beautiful. Very ingenious and well-done!
