Default RB S3 L2G ?

What pipe are you running, or would you run on this 3 port? Engine runs really well has just at a gallon through her. I can tell that I am not getting all I can out of her. Of course part of the problem is the cheap stock pipe on my XTM. I'm Open to suggestions.

well, RB sells this engine paired with the RB 2020...so either the 2045 or 2020.

The 2020 has a extremely short stinger to minimize damage, but it is hard to mount it such that all of the exhaust exits the body. Kind of annoying.

+1 to the RB 2020

I have the "Older" version of the S3 and run it with a JP3 pipe and its pretty peppy for a 3 port! Not a bad combo, I have also heard of running it with a Thunder Tiger 2035 so I have one on the way... Will have to give it a go soon...

Default RB L2G S3

I have one of those L2G S3's and have successfully podium'ed in expert buggy with mine. All the power is usable, very nice for the price.

I've run a JP-1, JP-2 and JP-3 on this motor, and liked the JP-3 the best.

Also this motor can be easily be "upgraded" to create way.. way... more power.

1. Exchange the crank for an S5 crank. (it has a turbo cut in the crank)

2. Port the intakes on the sleeve to gain additional top end and run time.

3. Run an RB #5 glow plug or a medium hot plug instead of the medium #6 plug once ported.

Some would sat "just buy an S5".... nope,.... the combo of the ported three-port with the turbo cut crank outperforms the S5. The three port is the key! Look for a deal online for an S5 crank, and pop that sucker in.... I found my S5 crank brand new on ebay for $40.00, paid $180.00 for the S3, and now I have a $220.00 screaming fast motor!

UndergroundRC.com has a porting video of how-to-port, its not even that hard and takes only 10 minutes!

How about a WS7 III crank with the S3 sleeve? Thats what I was looking into a few weeks back.

Now thats some serious info thanks. Not to mention I've heard of something like that before with this engine. What temp do you run yours at? Do you notice it seems to wake up at a certain temp? Some say this motor likes it hot. I've been hearing running it between 260-275 is optimum. I always think if your running it at this temp its going to spike at 300 on a good run. Maybe I'm just scared I like the engine so much don't want to hurt it. First engine I ever had that would literally idle while I refilled the nitro bottle. Put every thing away filler up and keep going. Not to mention the idle is insanely low.
