I'm gonna be doing a b16 swap with a y1.. (don't try to talk me out of y1). This is my DAILY driver and long distance driver, THEREFORE, does anyone with a y1 tranny know what the rpm's would be at 80mph or so? I'm thinking a crossover at about 4800 with the zdyne but I'm not sure exactly how tall the gears are in the Y1 and how they compare to the gears in the crx si.

I ask because I don't want to go on long trips with the vtec engaged and I'm not looking at getting a vafc or anything like that.

 

yeah man i have a y1 tranny at 80 mph i'm running 4600 rpms i get about 300 miles on tank its crx si too

 

i have a y1 as well, and can honestly say the gears suck, but for a good daily drivin car with gas mileage in mind, its a good tranny, at 80 mph im like at 4800 rpms, heading towards vtec, so i just cruise like at 70.
