TQ Engine Break-In Cautionary Tips
Be mindful that with high-compression Italian motors, you must take your time during the full break-in period of 1-1.5 gallons. Know that running-in these engines is the preliminary period prior to break-in. With an OS engine you can run-in a few tanks, and then race it without much concern. Not with these!
Otherwise you could experience premature connecting rod wear or failure. The most common sign of rod wear is the sudden case of blowing plugs repeatedly.
The TQ rod has an oil hole for the crankpin in the lower bushing, like most others. However, at the exit of the TQ oil hole inside the bushing, it is elongated for maximum oil flow. The drawback to that design is that the bushing is vulerable to over-rev damage when the fit of the engine is still extremely tight. So please be careful not to over-rev your new TQ engine while in it's full break-in period, especially if you flip upside down and try to get the attention of a marshal. We've all done it.
If you take your time and not race your TQ engine prior to full break-in, the engine's P/S/R will last a very long time, perhaps the entire season of weekly racing. However, if you race your TQ engine prior to fully breaking in, you will be advised to change the rod after 1-1.5 gallons, to maximize the life of your P/S.
Also, if you will be running 30% nitro, go ahead and add the extra 0.1 shim. This will help relieve some of the pressure on your new TQ mill, increasing cooling and mileage.

Im thinking of getting this engine. What glow plug do you recomend? P3, P4, P6 or any thing else better? Also will the GRP pipe work fine with this engine? You know the origianl one for the GRP motor. Does the motor needed sealed at all?
Thanks
Thanks

TQ plugs. H4/5/6 based on outside temps... But 99% of the time I ran h6 plug. I've used the 2069 and 2053. 2069 makes a tad more power. Fuel mileage is a little better too. If you can I would definately recommend the 2069 pipe. No sealing on the motor, was not needed.

As for pipes, the GRP 2053 will work really well with the TQ mill. Another pipe you may want to try is OS 2060 or Losi's RE-10.
Ha I found the list:

I use the OS 2060 pipe with my mill. In Truggy, 12 min easy. In buggy right on the edge of 10min with a semi-rich tune.

Are the TQ plugs similar or the same as the GRP plugs??

Picked up a TQ engine and I've got to say, this thing looks great. Unfortunately, it'll be a while before I can use it.
RoyJ- good info you've provided. I did that with a Jammin I had a couple years back, and it turned out to be an incredibly reliable engine.
