Ok. Check again. I think you may be confusing shorter with closer.
The facts are that the sr16 has shorter 1-3 than the ser but, the 4th gears are the same. This leaves a gap between 3-4. A wider gear spread...
It will work fine, just going to have an eeevvveen shorter first and awkward spot between 3-4, which sucks in the 1/4 mile.
