question on engine choice, i have been thinking of the speedline matrix rw and also the new R3. does enyone have recomendations as to which engine might be the better choice ? things to consider are fuel economy, power delivery and longetivity. thanksguys.

Hey Patto. I'm currently running a Murnan Modified R3 with the novarossi 2630 pipe. I love it. I've only done two race days with it so far & I can feel it's still breaking in. I had more power this week than last and managed a 3rd place. It's still running fairly fat as I don't want to push it too hard early in it's life. Can't say about the matrix as I haven't run one yet. Also there is a separate thread on the R3 here as well.

Which one is the better engine? I have the Xenon (not R)

Does the RB WSII use/interchange with the WSIII?

The only difference as far as I know is that the Xenon is ABC construction and the Xenon R is AAC . I have the Xenon because I feel that ABC construction is more durable , but mine is stuffed now so what would I know !!!

wow, this thread been in active for a long time, if there's a new one for the on-road motors please re-direct me there...

are the c9 c10 c11, the same, and more or less 35 plus 21's? thanks

The c11 is the better of the rb's you listed. It has a better piston material, and more rigid block than the older models. The rb is different than the 35+21. It has more crank timing, lighter crank, different block. The Rb has more top end than the 35+21. The 35+21, and Rb parts are not interchangeable without modification.

i got the classico10 and it a descent engine ..it came with the 3003 pipe imo the 2018 bring the engine to life..i got this engine because im sort of a newbie to onroad nut ready to upgrade to the C11 its look strong

so would you say the c9-c11 has more top end than a 35 plus 21 tuned? or just over the stock versions?....lastlly do nova pipes work w/rb motors, 2015 etc etc..thanks

also the c11 has a different p/s/r set than this?

Yes. They have more top end than the tuned 35+21. The novarossi 2015 pipe works great with the rb c11. I like the medium conical header with the 2015 on the c11.

but thats the same p/s/r/ as all three c9-c11..unless the c11 has a different part number? i just wanted to see the different piston on the c11...

The c10, and c11 have a lighter, more durable piston than the c9. I'm not sure of the part numbers without looking them up. The c10, c11 piston is definitely an improvement.

Will a Nova SCT crank drop into my TJ10?
