Turbo cg250 169fm
I have a 2007 Viva 250cc ATV . Wanting to convert it to efi and turbo it, anyone ever done this? Found this kit http://www.ecotrons.com/Small_Engine...o_PNP_kit.html
And http://www.ecotrons.com/Small_Engine...bocharger.html. as a start then weld my own exhaust and intake piping. Any thoughts or input.. |

We have seen the FI and turbo setups, but no one that we know here has tried it. I see you have the liquid cooled version.

Yeah any issues with the liquid cooled engines? Looks like I'll start building a turbo efi viva in a few months after the holidays.

They don't tend be as reliable as the air cooled versions. I would make sure everything for the cooling is in good order before moving onto a turbo setup.

It would be a fun little monster. If you search CG250 on Taobao, you'll find plenty of replacement parts and gaskets; those will be handy items, once you start to squeeze it.

I wonder what the compression ratio is? Most turbo engines run a lower ratio.

That is pretty high. Things may go boom quickly with the addition of a turbo.

I'll run high octane with a booster, worse case it'll blow and eat my legs right? Lol then ill have to figure out how to mount an electric hand shifter.

I'd try to run corn fuel; it's close to 110 octane, and it's cheap. You'd need to change the o-rings, but that's easy.

Got an email back from ecotron pretty quick:
Yes, our EFI kit and small turbo fit right onto this motor. No, you can use regular fuel. Different fuel, may need different tuning. We will support you to tune the system. Thx, matt |

So after extensive research come to find out a turbo pushing enough boost to make any more than 5hp would melt the engine lol so no turbo but i will try the efi and now wondering what other things I could do to make this atv crazy..... Nitrous? Any way to bore it or cam it?
