Well everyone wanted it and here it is, went ahead and installed the turbo on my Nypro project, going to snowy range this weekend to break her in.

Lots of that is good. one MEGA concern.

having built a similar setup on an RX1 power ski-doo a few years ago, your header is gonna last about 1 ride and melt and destroy itself. your now trying to put 3x the flow into one tube not to mention increasing flow per cylinder due to boost. i would not run it long like that. gonna have WAY to much backpressure and dangerous risk of deto due to huge amounts of heat stuck in cylinders. if you have to go into a "log style manifold" with one tube into the turbo you want to be at least 2.25" tubing from the collector back mine was only 2" and it would get so hot you could almost see through it and mine was thick walled stainless with a larger housing turbine.

My thoughts as well...
