whats cone washer for?
Goes between the CB and the screw that screws into the pilot shaft. Its specified in the MT2 18ss instruction kit....I recommend you refer to this when installing the new engine, CB and bearings....

also, will the associated tuned pipe work with the mt2? would it be better to buy the hpi one thats about to come out? Is anyone better than the other?
The Associated pipe will work fine - just need to get the mounting kit specifed above...the HPI thats coming out is specifcally designed for the MT2...as regards performance, no one will really know until they try it!
Is there a huge difference in speed and acceleration if i don't change the clutch bell and spur gear?
Even with the stock gearing, you'll definately notice that the CV-RX has a lot more torque and grunt off the mark. Top speed is quite a bit higher than the T-15, even with stock gearing. But you'll really want to upgrade your gearing to notice the true difference the bigger motor makes....
I'm definitely upgrading the fuel tank to 100cc i heard the o.s. engine burns through gas
Good idea...the O.S doesn't burn through the fuel, but it is a little bit thirstier than the T-15...however with the 100cc tank, run times are great and when its properly tuned, its lasts quite a while...
