I have a tmaxx 3.3 that i keep having problems with my carburator. i bought it from a friend but the hsn was stripped out so i robbed another carb off of my 2.5 tmaxx. Apon tunning the 3.3 the hsn again stripped out. My question is there any aluminumn carburator i could put on there to fix this problem. I just got into rc and im not to sure about things also i ws looking at making more power and was wondering if a dual turbo head ( http://rbmods.net/rbshop/index.php?t...product_id=228 ) would help or hinder performance. also if i get this head would i need a different aftermarket stock size carburator.
