Makes looking into putting a RS 57 mm throttle body on RT something to look into if cam & valves are same and no other major changes would need to be made
Not much bolt on mod's out there that would give you 6 hp. I have put a larger throttle body on my H3 Hummer Alpha 5.3L with SuperChips Mapping
and performance was greatly improved..

This was already shown to be a typographical error. Both throttle bodies are the same size (51 mm).

I stand corrected. I was thinking of the typo about the RS-S throttle body size. The RT (51 mm) and the (RS 57 mm) have different throttle body sizes. The RS and the RS-S are the same.

If that is the case then all the magazines and BRP website have it wrong. Im thinking not unless it can be proven wrong. Not to mention the manuals. The mapping is also different between the two.
