Okay, I'm having a problem deciding which tranny to get. My set up will be a B20B engine with an LS or GSR tranny. I just made a call and they said $600 for an LS tranny, and $650 for a GSR tranny. Now I know the GSR tranny will accelerate the car faster, but I don't want to be on the Highway going somewhere reving high all the time with fucked up gas mileage cause I do alot of driving, and race occasionally. Does anyone know what the rpms are in 5th gear at 70mph with a GSR&LS tranny, and what might be my top speed with a 7200 rev limiter.
