Just picked up my brand new Nitro Sport for about $270 from JEGS. I have 7 years in electric experience and I own 1 Bandit, a couple Rustys; XL-5 and XL-1. Here's where my question comes in. Besides the usual (suspension, aluminum, bearings, etc) what is there to upgrade in the engine and exhaust itself? I am familiar with any upgrades that are compatible with electric; just not so much on the PRO .15. I do plan on upgrading to 2.5 when I get really good at tuning. Thanks a ton!

Yes I'm sure there is some thread from 2005 that covers this but the Nitro Sport section on this forum could use a little love.
