Well for $230 you can drop a OS30vg in your CRT. I was very happy with both the engine itself, and OS's customer service. Its a full 2yr warrenty and that includes the piston and sleeve itself! The bump start version is $230us.
As for how the 30vg compares? The carb is a dream, no problems tuning it and it holds it forever. Power wise its right up there with a Picco .28 P3 and a Novarossi 528xs 3port, more rpm than the NR though. It is a .30 so its at the limit for truggy rules and will drink more fuel than a good .21 motor. The power band (I had mine in a 1/8th scale buggy) was very strong in the mid-range. I ran 17/46 gearing in my Jammin buggy and it would pull to 50+ no problem. But for a track you won't need gearing like that. A 14t would probably be perfect. When I finally sold mine I still had to heat up the engine with a hair dryer or crack the glow plug open a bit to get it to start on my bump box, I had a little over 6 gallons on the engine at that point
There are plenty other engines out there in that price range that are good though. Best reccomendation I can make is see what people are running in the truggy class. Get a list of the engines, then start comparing prices.
Unfortunately there is no SAE net standard for engines, no truely reliable dyno numbers. Seeing what people are running is pretty much the only way to get a good idea of what matches your needs.
