I am wanting to turbocharge my gy6. I happened across a sweet deal on a K03 turbo, so even though it will hardly get spooled by a 150cc I will throw it on and see what it can do. I have another challenge though. The K03 turbo is oil fed and cooled by antifreeze. Got any ideas?
Ditch the K03 turbo, it's made for 4 banger motors in the 1.5-2.0l range... Thats 10x bigger than your 150cc (.15L). My 150cc BARELY spools the RHB31, and its way smaller than a K03. As for the cooling by antifreeze, its generally accepted that any turbo can be run on oil cooling/lubrication only, regardless of wether it has engine coolant ports or not. So if you pick a turbo with oil and antifreeze ports, just block off the antifreeze port and run it on oil only.
anxious for updatessssss
Sorry man, its still running fine but i'm busy doing a GY6 swap on my brothers ruck. I think I'm running out of injector in the upper RPM's, although I can't get my wideband to operate properly to confirm this.
