What size turvo would you use on a 800cc 2stoke.
Stock it makes 140 hp, so I'm wanting to double it. It's a 2002 polaris, rev to 7800, weight is 600 ish lbs with me on it. Had it running a few years ago with a Iht RBH5, then took it a part because it was not very trail worthy. Now I bought a smashed up one and I'm wanting to put the turbo kit on it. Just wondering if I should change the turbo to something else.

A Garrett T3 "Super 60" would work well for you. As would a Mitsubishi 16G. A Garrett GT28 ball bearing turbo would work well but a little more money.

I have ran all of these on 1300cc Hayabusa engines, all will support up to 320-350hp when maxxed out.

I hope you have a killer intercooler, race fuel or boat loads of meth to make 280hp with 800 cc...because you'll be cramming 20 psi of boost in it to get there.

Can you turbo a gas two stroke?

Check out snowest. Lots of similar setups.

It will be on c-16. Good intercooler.
Snow west is were I got most the info when I out it together the first time. Very good site, just hard to find any "flatlander" on there. I'll probably start with 10 or so psi and work to 20+. It's just a toy to run around the neighborhood.

Im glad you posted this. I take a shitkicking at work for owning a POPO quad. And they are all about skidoo. Now i wanna buy a POPO sled and turbo it to blow their skis off. Just to shut them up a bit. They talk like they know it all but they constantly break them and couldnt clutch their way out of the garage from the sounds of it.
Ive never owned a sled so i sit quiet. BUt i got a feeling with some decent hardware i could leave them in the dust. Good guys though. Just gets tired of hearing the know it all routine with busted **** steady.

I run a Garrett 2860 on my Ski-doo 1200. Makes 300hp on 18lbs. I've never even looked into a two stroke though so I'm not sure if the application would be the same.

Holy *****! That thing must MOVE

I guess you got your build sorted out. How far have you driven with the turbo on there? Maybe you should come down and give my co-workers a hand. LOL.

Not very far. I got it sorted out right at the end of the year. I've only driven it on 6lbs and it was a handful. Had it dyno'd and the 18lbs was on race fuel. It will never see that much boost unless I buy a new clutch for it. Mine is good for 250hp or so.

GTX 2867 for your goal although GTX 2863 would be more useable all round.
Expect a lot of issues with aiming for 2X power [ 2 stroke 800 ].
4 stroke snowmobiles can do 300+ all day long and much more in race mode.
