Well I dont know about soon. It still may be a while for the release. I just rebuilt my 5T from the chassis up almost completly with the addition of X6 shocks so I'll be good for this season. I just had way to many spare parts around so I figured I would rebuild instead of buying new.

Mark, what setup are you gonna run on the mbx6 for motorama?

Anyone have any details on the "9" series of engines from RB?

Also, I posted this on the other RB thread in Onroad Nitro Engines but not sure where I would get better responses.. so I'll ask here too:

I'm looking to get a new engine for this year in my 8ight 2.0 buggy. I'm trying to decide between the S5, S7, or WS7. I have an RB 2045 pipe and 192 header that I would like to use, but I would buy a new pipe if the engine choice called for it.

I'm still fairly new to nitro so I'm looking for durability and reliability first and second, performance would be third on the list. Most of the tracks I'll be racing on are medium to large - for example The Farm 2 is a few miles from my home and will be open for club races this year. That of course is the largest track I'll be racing on, with the others going down to about half that size.

I would really like more low end which makes me look to the S5, but I wonder if that will have the pull on these bigger tracks. Better fuel milage would be good too, I'm not a great driver so if I can make up some time by getting one less pit stop I could use that help. :nod:

My first nitro engine was an S7 (older model) that I bought used with about 3 gallons on it. I put on another 4 without hardly ever touching the tune and that durability and ease of tune is what I loved most.

So I guess what I'm asking is what model do you think is best for me? The price difference between the three is neglible to me, although cheaper is always better. What pipe and plug combo works with each model would be great information too!

Side question - I've heard ceramic bearings are a good improvement. I was considering swapping both bearings for TKO ceramics after about a gallon of break in, any pros or cons to that?

THANKS!

Hey guys im thinking about getting a turbo button for my standard c6. Is there some kind of mod that needs to be done, or just pop it on. Also will i need to shim it different. I run 30%. What will i benifit for doing this?

BIG RE 02-10-2009 08:59 PM

what do you guys think is the best rear bearing for the ws7III, everything I have tried sucked, the only other one I see is a newer boca with 11 balls instead of 9

Whats up G..... There is nothing to it you need part number# 01082 for the head button and I would shim it with one additional .1 shim to help prevent detonation with the 30% nitro. I will see you at Motorama and we can talk more.

Hello, im getting a rb s5, it was broken in on 20% it is the l2g and it has a standard plug, if i am going to run it on 30% do i need to shim the head?

I have a RB S3 and was thinking about running it with a JP 3.

Or would a 086 be a better option?
