hey guys , im doing a zc swap into my 89 crx hf, im putting an SI tranny on it. but my problem is that ive seen the same swap done on this car before and even with the SI tranny, in 5th gear gonig like 70 your at 3500rpm. now this on the strip isnt that big of a deal, but this car is my daily.and I would like to not own a 4cyl highway gas hog. what gears are compatible with this tranny that can change this in a good way.

thanks in advance.
