The Honda maual transmissions have an internal pump that is designed to use low viscosity oil, which is the reason why Honda MTF is roughly the same viscosity as 10w30 engine oil.
Synchromesh is significantly thicker than MTF and engine oil, which is why it "cures the grind." It leaves a thicker coat of oil on the gears. Most people would say this is a good thing, right? Well, you have to remember, the pump is designed to use engine oil/MTF. The gears are also set at a closer tolerance than the GM gears (transmissions for which the Synchromesh was designed for), so you're not really doing any good for the Honda transmission you're putting it in.
If you want to nit pick, you'd probably lose a few WHP due to extra drivetrain losses from the thicker oil in the transmission.
