Custom Parts. Ex "Turbo"

Does anyone know a good website I can get custom model parts off like turbos and roll cages and stuff. We only have 1 hobby store around here and they dont have anything practically

You will have to scratch build roll cages with styrene tube or source one from another kit and modify it to work in the kit you're building.

As for turbo's (I think this is the third time this link is being posted today):

hiroboy's is the best site for the turbo's but the only downside to it all is that it seems that they always out os stock

Hiroboy's parts are from Parts Box in Australia (http://www.thepartsbox.com), amongst others. Parts Box have a wider catalogue than available at Steve's store and they do accept online orders directly if Hiroboy doesn't have them.
