Help! my Losi XXXNT2's engine just ran for the last time. Im upgrading but i cant decide between 2 good engines:the O.S. .12 tz with a rotary carb or the the O.S. .12 CVR. Ive been running electric for 6 yrs and im not 2 sure. Whats the difference between them? i know that both engines are good but which is better for racing? Please help! this is the first nitro engine i've had to buy :confused

They are both GREAT engines. Both me and a buddy run the .12 CV-r in our stadium trucks(he has a XXXNT AD2) and they really run awesome. I took first in the A Main with mine and my buddy took third. The TZ turbo motor has more power but is more than twice the price and is a little finicky to tune. Either one is a great choice, just depends on what you are willing to spend, but I would say save $130 and get the CV-R.

In addation to being more expensive doesn't the TZ require special, more expensive glow plugs?

The TZ requires turbo glow plugs, they are comparable in price to standard plugs. They are just more tapered on the threaded end.
