I plan on turboing this car in the future and figured the 5 speed would have better gearing than the 6 speed with the boost. Why do u say it’s gonna suck with the 5 speed?
Yeah, that whole "long gears for boost, short for N/A" thing is not quite as simple as it seems. If traction problems weren't a thing, short gearing would still win out most of the time. But these cars are FWD Hondas and traction problems ARE a thing. Ideally, you'd solve it (as much as possible) with the proper tools (traction bars, tires, etc.). Pairing a longer-geared transmission with a turbo is the poor man's solution.
And like I said, it's not an either/or type of thing. The characteristics of the turbo you're using should be considered as well. It's possible that a longer-geared transmission or a Frankenstein transmission with a combo of longer and shorter gears might be the best fit for a particular build. You'll see that a lot on B and D-series setups.
And x2 on what Inzain08 said.
