Turbo Xterra going Twin Charged! M122!! 

This is awesome. Just purchased a 2004 Xterra and I love it, can't wait to see what happens with this project. I see you uploaded an update 10 days ago, Ibhave that video queued up now 😄

Looking forward to this build! Ive often thought about something like this for the vg33er in my frontier

Nissan actually had their own Twin Charged car, the March Super Turbo! Those things sound super cool.

Eaton part number is the cubic inches per revolution. IE 62 in^3 or 122 in^3. About double. Stiffness at the blower joint helps. Instead of rtv, consider using either OEM gaskets or milling in an o-ring groove. McMaster sells a kit for making custom length o-rings. Will you stuff a heat exchanger or intercooler into the loop? I suggest you do NOT delete the bypass. Instead plumb the actuator diaphragm to manifold pressure. Under vacuum the actuator will open the bypass. This happens during idle. The bypass shuts under positive pressure.

Cool project! Would be great to see an off the shelf adapter one day. Surprised the vg33er never saw after market support for a procharger

Just for reference for when you’re at the mapping stage, when going compound charged, you can’t rely on MAP for accurate fuelling, you’ll also need to measure air mass (MAF). Manifold pressure and temperature isn’t directly able to be extrapolated accurately when you have varying sources of air flow being directed. Same as when have to remap for a different turbo size change.

Really cool. The first thing that came to mind was a waterjet to have a perfect cutout. The fact that you cutout the piece with a bandsaw is very impressive.

nice those VG can sound incredible I wanna build one

Heads up, the volkswagen car you're talking about has a 3.2 VR6, hence R32. The 1.4 TSI is the name of the twincharged engine

I can't attach pictures, so this will have to be a thought experiment. Turbo-charged engines do not need headers. You probably know this, right? Similarly, supercharged engines don't need a free-flowing supercharger manifold. Take the VG33ER manifold and weld flat plate to it so the M122 can bolt to. Don't worry about the "free flowing" design. Just make sure the exit V is inside the manifold cavity and make the intake cavity air tight. Done.

Would the 300zx turbo parts fit the vg33? Got an 03 frontier i turned to a prerunner and was wondering if the ZX stuff would bolt in without any major issues. New to the channel and already liking the content 👍

And I need a vg33 for my 2002 X. Can't find one here in Canada.

Im following this, trying to figure out if i can push more power to put mine in a sandrail.

how did you make the template to line up with the belt drive for the super charger, is there a dimension between the front of the plate and the belt?
