Well I thought I would try my hand a building an exhaust manifold out of steam pipe. I have a rough idea on the cost of parts - $100ish. The YD25 exhaust manifolds are made from cast iron and have a habit of cracking. If anyone knows my build then it will be running significantly higher boost than most Navs.
What I need to know is how would I go about bolting it up to the head? Do I reuse the flange and just cut the rest of the cast iron off? And what would be a suitable size pipe to use? 1 1/2" or 2"
Turbo will be in the same place as the old one so I don't have to redo too much of the exhaust.
Cheers
