Recycled exhaust manifold

I attacked my 1.8 manifold with a 4.5 inch grinder and a stick welder.
https://www.miataturbo.net/attachmen...ine=1337103680 4 hours later and voila! my no hit block special is born :giggle: https://www.miataturbo.net/attachmen...ine=1337103680 https://www.miataturbo.net/attachmen...ine=1337103680 https://www.miataturbo.net/attachmen...ine=1337103680 https://www.miataturbo.net/attachmen...ine=1337103680 https://www.miataturbo.net/attachmen...ine=1337103680 https://www.miataturbo.net/attachmen...ine=1337103680 https://www.miataturbo.net/attachmen...ine=1337103680 next step vband! |
Holy sh!t that is so damn boss!
Props to you, good sir! |
Nifty
You used to see this stuff all the time, then everybody got baller. |
That's awesome, really impressive work.
|
I need a welder.
|
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?
|
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 |

(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. |

This guy gets double props from me. Yessssss!

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

very cool

Hideously beautiful. Very ingenious and well-done!

This thread was great until the stupid cutout was posted.
