Another boat restoration thread!

Turbo I went with is on the right, 9b on the left:



Pic I took during a head change to one with titanium retainers and spring shims, also with Supertech inconel valves to take the higher RPMs, rev limiter upped to 8650.

That's awesome! Any pics of the exh mani you built or did you do just an extension off stock mani? Did you get it on water yet to test acceleration and top speed?

It's an extension off the stock manifold. Double walled stainless for water cooling, downpipe is dual wall for about 8 inches to get past the external gate entry then injects the water into the exhaust. Turbine housing is not cooled currently because I think I'm going to go with a bigger hot side. Instead of welding a jacket to the housing I'm going to use a copper coil. I haven't taken pics of really anything yet.

Yea, been riding it all summer, it's like a whole new ski now, acts completely different. Top speed is pretty slow due to the hull bottom being screwed up, but it makes enough power at 12 psi to redline a 15/22R prop that is pitched up to like 24. I just did it for the noise it makes.
