It is indeed a customisation Michael. I lack enthusiasm for attaching a turbocharger to a mixed-fuel 2 stroke because a dirty stream of carbonised oil in the exhaust is not good for the turbine's health and longevity. My one and only home turbocharging experiment, on a 6 cylinder Vauxhall about 45 years ago, failed partly because the center bearing of the turbocharger didn't drain its pressure-fed oil well enough, causing oil to be injected into the turbine, which carboned it up so it ceased rotating. As it happens it wasn't a great success anyway: I had a turbocharger of the correct size for the engine's displacement (138 cubic inches), but the intended engine (a Chevrolet Corvair) ran to 6,500 rpm while my Vauxhall tended to bounce its valves at about 4,200, so the gas flow rate was far too low and I only achieved 3 psi boost pressure, which had a barely noticeable effect on the car's acceleration. (The same turbocharger worked excellently on a 179 cubic inch Holden red motor, though.) I'm told most home turbocharging projects fail.
The turbochargers I've had dealings with require pressure-delivery of clean, cool, filtered oil to the center bearing. If they don't get that, the center bearing lasts a very short time. The mass flow of air and exhaust has to be accurately matched to the size of the turbocharger. Even if you do all that and the dirty exhaust doesn't wreck the turbine, crankcase induction 2 strokes do not adapt terribly well to any kind of supercharging, since at best they dump most of the pressure out of the exhaust port during the first part of the compression stroke, so the effects on power output are quite small. In brief I think this is a dumb project, but then I suppose no project is dumb if you have fun and no one gets hurt.
