Default OS XZB vs. Novarossi 21-4

Hey guys, just wondering if anyone has used the OS XZB Blue Head and Nova 21-4. If you have, what did you like better, and how did they feel comparing the two engines, I currently run the cheaper OS XRB but there just an entry level engine and I prefer to have it as a spare, but when it's let's go, I'm might make the move to Nova, just not sure right now.

Hi Cory I have an os max XZB 21 and I have it in my Jammin X2 CR buggy and it is just the coolest engine I have ever had. I've ran alomst 3 gallons of fuel thru it and it just pures. It has good overall speed on the straight aways and out of corner power is awesome too. I have a Jammin JP4 pipe and i just love how much power it makes. The new XZB II is supposed to have the same HP rating as the spec II speed but at almost 150 dollars cheaper its worth it in my book. Michael

I've got both. Honestly I would trade my is for 3 +4s but not 2 if u get what I mean. The os has power, tunability and reliability over the nova. But I'd still take 3 for my os because the novas have smooth linear power that is very very VERY controllable.
