Hello folks, can someone tell me what the "R" stands for in the 2.5r.....Im assuming Racing, but is it a big diff over the standard 2.5 motor?..what are the engine specs..thanks..!

its the same motor, but rumor has it that the internals have been messed with. (port timing etc.) also the exhaust, head and gas tank (that are all new) play a big part in the performance of the 2.5R.

I think that it might be REVISED or REVOLUTIONIZED.:D

It probably stands for REVO.

I don't remember it being stated that internals were adjusted, but it was rather "hinted" to us. They did say that the exhaust was designed to boost performance though. I would think that the "R" stands for racing since almost every aspect of the truck tried to increase performance on the track.

be cool if the 2.5r fits nicely in a maxx without flaw. even better if it is under the replacement program.

I was at the RCX show this past weekend and i specifically asked the rep what the diff was between the 2.5 and 2.5R. He told me that some carb changes have been made, the head was a lower profile head to reduce CG and the engine had a little different porting than the standard 2.5. This is exactly what he told me. I stood there for a good 15 minutes and we rapped about all the innovative features on this new truck. He showed me the 2.5 maxx driveshafts vs. the revo he showed me the new carbon metallic slipper pads and brake pads that they had an effective range well over 500 degrees and how the internals of the tranny are much stronger and durable than the maxx. So to answer your question about the engine yes there are differnces from the standard 2.5
