I'm converting a nitro 4 tec .15 to a 3.3. I have read that the .15 gears are not suitable for the 3.3. Can you guys please advise me as to what gears to use. I need good acceleration in 1st and a lot of top end. Which clutch bell and which spur gears do you recommend? Thank you.

I would check a chop shop on ebay,you can get all new spur and a clutch setup for around 30 bucks

OK, but what I'm asking is which ones? I don't know the gear ratios. I see there is a 20 tooth clutch bell available and I don't know about the second gear. Should it be a 43T. 41T, and I see there is a 37T. I've read that the gear set up on the .15 is not suitable for the 3.3 conversion.
 
for the spurs the 2.5/3.3 is 41/45 out of the box optional is 41/37
I haven't checked into the cb gearing yet
