I have 91 civic got b18a1 out of 90 integra whats best i can get
Depends what you’re doing with it. YS1 is the best cable trans but has a short 5th if you do much freeway driving and are hard to come by. Much easier to find a B16 trans with similar ratios. I swapped a hydro gsr 5th into my ys1 and it’s way better freeway cruising now.
