Default GRP or RB?

I am looking to buy a new engine, but I was looking for either a GRP or an RB. I also wanted to know what’s good and bad about the engine.
Thanks

GRP! I'm an OS guy, but if the O'Donnell or Reedy don't make it out soon my next motor is the GRP Promo.... I did some research and found a lot of positive remarks about them.

go with the grp. I have both the grp tuned and a rb s7 l2g. Grp makes more power and goes longer on a tank of fuel

No offense, but a GRP more than a C6??

Sorry, my vote is for the RB, I have seen too many problems with the GRP.

GRP got the promo kit about a year ago and have had no problems. Great fuel milage and easy to tune. Switched from Os and will never go back

Who said anything about a c6? Rb does make great engines but you can buy a grp tuned right now for under 280.00

Default GRP

I vote GRP I have had 3 of them and very few issues besides the usual stuff. Great controlable power and well into the 7 gal mark and still strong. I have heard RB's are hard to tune but I have no personal experience.

You do know that Novarossi makes RB engines? Ive been researching RB engines alot as the S5 pro twister modded will be my next engine, and everyone says they are very easy to tune and tune just like Nova's.

Under $280?
Where you lookin at?

Maybe for the sport "non tuned" motor... Not the tuned!
