Wanted: napsZ exhaust manifold

Post by jovial_cynic » 31 Jan 2004 16:09

I need an exhaust manifold off the napsz engine. I want to start working towards a turbo setup, and instead of starting with new metal, i figured it'd be easier to take an existing exhaust manifold, cut it, and weld new tubing to feed the exhaust into a turbo. i'd cut the one i've already got, but then i won't be able to actually drive my car.

so... anybody got the manifold? it doesn't need to be pretty, and it REALLY doesn't need to be expensive. ;)

The exhaust manifolds are cast iron, you'll have a heck of a time welding steel to it.. at home..... Unless you’re a really well qualified welder. Cast iron is tricky stuff. The best you could do is trace out the exhaust flanges, make them out of plate steel, and then go from there. This is the usual way to make a manifold.

oh. since i am not a well qualified welder, perhaps plate steel shall be the way to go. how much does plate steel generally run? including the flange and the tubing... what kind of price are we looking at?

Steel is cheap - especially the small amount you'd need. 3/8 mild steel plate is all you require, but it's kind of hard to work with, if you are limited with tools, it'll just be time. And since most of us 510 guys would spend inordinate amounts of time to save $$$, you're in. I love this crowd!
