ORIGINAL: the iceman
I have a stock mt2 rtr. The t15 engine sucks and wont hold tune, so im thinking of upgrading to the o.s. .18cv-rx w/ rotary carb (i heard it was good). im also thinking of upgrading the clutch bell and the spur gear, but im not sure how many teeth for the clutch bell as well as the spur gear. I wont good top speed as well as good acceleration, that does not limit the capabilities of the engine. also i want to upgrade my tune pipe, is this a good one:

OK, heres what you gonna need to run the OS. I've arrange it from bare minimum to other stuff which is nice, but not required initially...
BARE MINIMIUM:
============
1x OS .18 CV-RX w/11J Rotary Carb
http://www2.towerhobbies.com/cgi-bin...&I=LXGGP7&P=ML
2x HPI Heavy-Duty Final Gear Set P1x38T/P1x13T
http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXJYM2
1x HPI Engine Mount 20mm Purple
http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXCLR3
1x HPI Hex Wheel Hub 12mm Silver (4)
http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXJYM5
ALSO RECOMMENDED:
===============
1x HPI Racing Clutch Nitro
http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXLW03
1x HPI Racing Fuel Tank 100cc Nitro MT2
http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXJFE2
(the .18 does go through the fuel a little quicker, so its nice to have a slightly larger tank..also the 100c tank is primerless which means no more leaks!)
If you want to upgrade the clutch bell you can, although it is not STRICTLY required intially. If you want 2 though, I would recommend upgrading to proper bearings instead of the needle bearing that comes with the stock RTR. here are the parts...
Its also worthwhile upgrading to the same gear ratio as the 18ss which is a 15T CB and a 49T spur...
1x HPI Racing Clutch Bell 15T
http://www2.towerhobbies.com/cgi-bin...&I=LXLST7&P=ML
1x Bearings for CB
http://www2.towerhobbies.com/cgi-bin...?&I=LXD115&P=V
1x Cone Washer
http://www2.towerhobbies.com/cgi-bin...I=HPIC3245&P=K
1x HPI Spur Gear 49T Savage SS
http://www2.towerhobbies.com/cgi-bin...&I=LXFKM1&P=ML
TUNED PIPES:
==========
The THS one you mentioned (
http://www2.towerhobbies.com/cgi-bin...&I=LXCPX4&P=&I) is pretty good apparently, but there are ones a lot cheaper if you don't want to spend that much...
