I am curious, I have no idea how tranny's work ratio wise, especially Honda transmissions. But using the calculator here http://crx.honda-perf.org/math/index.html I came up with a proposed solution to my tranny issues. Is it POSSIBLE and how HARD is it to put an SI final drive into an HF transmission. From the calculator, an HF tranny with the SI final drive will yield the same ratios as an SI/DX tranny with an SI final drive. Any info is GREATLY appreciated. Thanks

 

i think that the hf tranny will take to long to rev up because of the longer gear ratio. just use the si tranny and forget about switching the final drive of the si to the hf. Its not even worth it.
