RB Concept S3,S5 or Novarossi N21B
I was considering buying a new RB concept engine based on their durability and performance. I would be using the engine on a buggy on an indoor track.
Would the S3 have good enough performance or should I get the S5?
Would a Dynamite 086 pipe be a good pipe to use on either of these engines.
I was also considering a Novarossi N21B engine. How does this engine compare to the S3 and S5? My main concern with the N21B, is it has a metal carb.

All three run great. I really like the S3. It runs really well for such an inexpensive motor. If you find you need more horsepower, get a good modder to rework it for you and it will run with almost anything.

i have the novarossi 3 port and it is awsome i had problems with the carb that came with it and i put the carb from my rb s5 on it and it works perfectly now the rb s3 should be pretty much the same engine

Main drawback that I found was that the break in process actually took about a Gallon +. However when it finally was broke Daaaammnnn she flew. I am approaching the 6 Gallon mark and this engine is still screaming. I followed the manufactures breakin guide worked excellent for me. I dont want to get into a heat cyclying vs other methods.
If you happen to get one remember get the bottom end tuned 1st. It should load up after 10-20 seconds. keep the bottom on the rich side. Onec you do this you can basically call your temp by leaning or richening the hsn. Can guess my temp with in 5 degrees. Dang I love this engine.
Before any nay sayers jump in there are other good engines out there. I just found this one to perform with ease.

Oh yeah, I almost forgot. The 086 is probably the best power pipe but will be illegal for roar races starting next year. A 2045 or 2013 is probably the best of the legal pipes.

+1 on the RB S3
I have one and it screams! Very reliable engine! at 1 1/2 gallons all I have done is replace the front bearing with a ceramic one (due to a lil leaking)...
I am thinking about throwing a con rod at it soon.
Yeah the RB line of engines seem to like the bottom end a "hair" fat but once you get this set it its easy from there, tune the top for temp and or performance... Just make sure theres smoke!
I use the 7mm carb insert and run a JP3 pipe but am considering the 2045 I have layin around...
I have heard the 2020 RB pipe is excellent too...
1 last thing, its an excellent deal for the money!

I run the n21b and love it.
I have run both an 086 and 2035 pipe and was happy with the performance. The 086 really woke up the top end and the 2035 gave me a little more punch out of corners.
The engine is really smooth and holds a tune very well.
Couldn't be happier!
That being said, I don't think you can go wrong with any of those you mentioned. The n21b, s3, and s5 all perform exceptionally well for the money. Build quality is great, so longevity is going to be there too.
