A few years back I bought a Toki 15 from ebay. I didn't know what to do with it then and certainly don't have a clue today. I just wanted to have a nitro engine and flick it to start.
I recently scratch built an electric foamy and would continue in that direction. Although I do have a cox 049 and some nitro fuel which I use to show off to my family and friend's Kids.  

So I was thinking instead of it rusting around what could I really do with it. I don't really want to put in more than a couple of Ks into it. and for sure making a nitro car would be good idea but I think that is way out of my budget.

Any scratch built or other budget ideas are welcome. or I may sell it off too..  

By the way I have never run the engine. It came with the bench test run only. So its new out of the box.

Make a slot cart or RTP cart, you just need a chassis with wheels and engine that can round and round in the slot or while rooted to a point
And do not run that engine with the prop you have pictured, that engine does not have a prop driver 

Those are good ideas.
Sir any DIY link or images would help me a lot.
Thanks.

By the way what is a prop driver?
I thought the props can be run using the extension plug as seen in the picture.
