There are Nitro "Jets" like those on that link.

Then there are Turbine Jets.

Both need to be put together and not all of the items you need are included in the kit.

You must purchase the rest of the stuff seperately.

A real turbine engine can start off costing you over $2400.00 USD and they go up in price from there.

A turbine jet will end up costing you well over $8000.00 or so.
