I just have it for bashing and stuff. The way I look at it is if I am gonna go through and spend money on a new mill then I want to make sure I get what I want. If you guys think the RG will suffice then I will more than likely take your advice and go with it. It's just a typical of me and prbably heaps of other people to go with the biggest and baddest you can fit in.

I'm with SManMTB. Anything bigger then a .21 engine is unnessisary in a buggy. You just don't have the weight or the drag in the drive tran (like the monster trucks do with those huge tires and weight) to need all of the torque that those big displacement engines have. With .21s you will get more RPMs and the RPMS tack up faster when it gets into its power band. I'm racing the sportwerks .21 right now and I can break loose all 4 tires on any terrain that I've driven on yet and it still has high RPMs. There are some good big displacement engines though that wont murder your wallet... I've raced the mach .26 for a while and I've driven quite a few sportwerks .26 engines. Both only $140 and you can still beat people running those high dollar engines around the track (not in a drag race but and engine wont help you in the corners). Any of the engines that I stated make more power then the O.S. .21 RG, they are all very easy to tune and hold it well, they last just as long as the O.S. RG, and not that much more expencive. The RG is a great engine too... there are people running them at the local track and all you need is a polish job and a JP-1 pipe and that thing will scream.

Thanks for the advice. Pardon my ignorance but what do you mean by a polish job?

Polish job as in porting and getting it polished up (make it shiny ). The porting alters its timing and will make it a lot faster. STay .21 and be happy! [8D]

Yeah but I didn't mean porting too. Polishing the inside of your crank shaft and the outside of the ports on your sleeve will let fuel and air flow a lot easier giving you a more efficient running engine.

You can also port your engine which requires some grinding on the outside of the sleeve but it mainly redirects the fuel flow into the cylinder and it can change timing. I don't sujest doing that untill you understand how these engines work first.

It doesn't change timing unless you grind on the upper edge of the port.
No worries.... grind away.

What about something like this? [link=http://cgi.ebay.com/NIB-OEM-SH-21-Buggy-Engine-ABC-W-Pullstart-2-4hp-RTR_W0QQitemZ6047304950QQcategoryZ34062QQrdZ1QQcmd ZViewItem]SH .21 OEM[/link]

I know that parts would be hard to come by, but considering the price, I'd consider it a disposable.

wELL, IF YOU WANT TO GET THE NOVAROSSI GET IT AND THE jp-2 off of nitrohouse its really cheap there, andnthey have good service.

..... and if it doesn't perform to your liking you just wasted $70.......

OS, RB, Novarossi, JP - you can't go wrong with any of those. You get what you pay for...remember that. Still want more than the OS .21RG, the RB Eco .21 is $179.99 and has plenty of power.

Forgot about the Eco. Haven't tried it but teh quality should be great.

Great engine for those on a low budget.
