that should point you in the right direction!
I guess it won't work, I don't think that engine has a turbo head.
i think i liked a A8 os plug in my rg.
Should I get the O.S. 21 RG or O.S. 21 RG (P) or is there any difference?
I think the (P) is just for the Pullstart engine. If you plan on using a starter box, Get the regular one. The lack of the pullstart backplate frees up the engine for better performance.
Neither one have a pull-start. Ok this would be funny if it were the difference, the (P) version says it comes with a poster Smile

Edit: the crankshaft is longer on the (P) version 30mm compared to 22.5
Sorry for the endless babble but anyone have comments on the Ofna Hyper .21 8 Port Race Non-Pull Start SG?

I know George had one for sale, and it might still be....
Man, I'm not sure what is more painful, choosing which engine to buy or a root canal.

Anyway, I finnaly said the hell with it and got the .21 RG (P). The (P) version has the better carb I believe.

I went ahead and ordered a crowd pleazer body also, time to ditch the Stampede body, since I painted the outside everytime I get fuel on it the paint comes off Smile

Anyone know the Werks racing clutch will work with this engine?
Hyper 8 port race is a great budget motor....very fast and very affordable. RG won't be as fast but it'll be fast enough!
The Werks clutch should work just fine.
Twisted Toys (for those of you who know him) said the buggy Werks setup is what I need so put that on order. Now I'm wondering if I need the same Ofna CB I had to get for the Savage Werks setup?
I may get one of the .30 OS engines for my Savage.
Ive heard very mixed reviews of that engine
True. I'm not always a believe that bigger is better.
ive heard more bad then good about that .30.
Yeah, me too i was tryin to keep an open mind though
If you are going with a .30 make it the collari...
If your going to buy a .30 stay in the back yard! LOL!!!



Seriously my buddy Balt bought a mach .28 at his local hobby store a couple weeks ago and that thing is a hulking beast... pleanty of low end grunt to throw a truggy around! And at 150 bucks it quite a deal.
To be honest, I don't even like a .28.
I've got a nice Collari .30 w/ roto-start that was in my truggy I'll sell...
That thing totally ripped!
I bought a modded NR528XP Big Grin
That'll rip WAY more!!!!!!
