There is a turbo kit for a 700 raptor, but the mounting is nothing close to a ttr. Funny thing is I was just thinking of how a turbo could be mounted to a TTR, since I have a spare one from my saab 9-5, but I think it's too big! lol
So just for giggles I put the spare turbo from my saab 9-5 to the exhaust. The turbo was free spinning and had plenty of oil on the bearings FYI. I was surprised, at Idle I would say the turbo was spinning at 1,500 RPM. I know it's not a lot but I was expecting the turbo not to spin at all. I revved the bike up to 3-4,000 RPM but felt minimal wind from the compressor yet again, I never covered up the boost pressure nozzle hole from the compressor housing. It was fun though lol
