Default Engines...need opinion.

My budget is around $150-$200.
I have owned before hyper 4 port then xtm pro .21 and now a v-spec.
I'm looking for a backup engine that i will be able to use in a race if i have to.
Competition has Collari B7, RB ws7 II, Novarossi P5X, Jp,...

I'm posting some engines that i have found but need your opinions on them:

Collari B3

Novarossi T21BF 3 port

Novarossi T21BF 3 port ....ABSOLUTELY!

This little engine rocks! It does take a long time to loosen up though (mine took two gallons). I run it with a Novarossi 9886 pipe, short header in my MBX5. Mugen alum shoes with 1.0 springs. I get about 7-1/2 minutes on a tank. My X5 tech's out at 124.1 cc's at Round 1 RC Pro Series NorthEast. Track is very off-road, lots of doubles and triples. Two straights. Lap times in the 37-38's (for me that is....LOL Pro's run 34-35's).

By far the best bang for your buck in the Nitro engine dept.

The Collari B3 is also a good engine but the Nova should out last it. The Collari's have varying results regarding service life. Both will last longer than the Hyper or SH.

i've got the STS 21, and i'm really happy with it so far, lots of power, i can hang with anything else at the track, and i get rediculous fuel millage, after a 6min race, i still had a little less than half a tank of fuel in my matrix, running at 200 - 220,

never ran any of the others, but have heard lots of bad about the collaris so i would probally stay away from them,

Which STS have you run?
The D21T or the Dragon?
How is it compared to top end motors like v-spec,p5,ws7?

i've got the team version, with the green head, i think dragon is what the D stands for before 21, i had an AXE LSK before, and power wise its basically the same, they run very very similar, and down the straght i can keep up with any of the RB's, OS or Nova's at the track, and one thing the STS has going for it, if you do need to rebuild it, the parts arn't nearly as expesnive as the top end italian motors,

i've only got around 1/2 - 3/4 of a gallon on it thgouh, so i dont know how long they last for first hand, but i've never heard anything to bad about them, and in the time i've run it, it hasn't lost hardly any pinch, and i'm told it keeps breaking in into the 2nd gallon, so it will get even better than where its at now,

Be sure to purchase a heat gun w/ a high end engine like the nova. If you heat it up before you run it each time you should expect a good 10 gallons of run time out of the engine.

if u cant get 10 gallons through a nova then theres somthing SERIOUSLY wrong...ive run over 15 gallons in my thunder tiger pro21bxr and i totally cane the engine and it still pulls the amazing 100 metre wheelies in my savage.....and i just ported it and i can prolly do the 200 metre mark ....

i highly recommend the thunder tiger pro21bxr........its an insane engine to own ...... its got way too much power in it tooo
