whats the biggest motor that you can put in it without having to do any motifications to the chasis?? mine dosent have any compression.:\

I'm assuming it uses a small-block engine. The biggest you can fit is a .18 engine.

Well, you could go with Wolfpack Radical's conversion. They have a .21 and a 4-stroke conversion believe it or not. Check this link out. Hope this gives you a better idea.

now that you showed me that i might have to go with it. haha

Haha, i was thinking about it as well so i emailed them to see where and how i can order it. I will let you know of the cost and everything as soon as i find out. I think it will be around 50-60 bucks for the conversion...hopefully.

Honestly I've got an O.S. .18 in mine and its more motor than you could ever want or need. I can't imagine a .21 in it.
