Hi guys, I just purchased my first nitro car last night, its a Smartech Winner 1.  I payed $80 for it and it didn't come with the engine. He threw in the pipe and the manifold for the original 15cxp engine.  My question to you guys is this.  Would a 18cxp or possibly even a 27cxp fit/work in this car?  I wouldn't mind making a few minor mods to get it to fit but I don't want to start chopping the whole car appart.
