I have searched and wasnt happy with the results.

I have a 92 db2 and I am boosted. Right now I am running the b17a1 tranny (same as a b16) and love it as I am at 337whp. I am going to be building my new b18c1 block I just picked up and goals for next year are 430+whp pump gas, 500+ c16. I know the b16/17 are the shortest gears, and if you can hook, there the best to use. I currently have a CC stage 4 clutch that I will need to upgrade to a stage 5 which is the main reason why I am thinking of switching to the b18c1 gsr tranny. I have a cable tranny so If I keep my b17 tranny and buy a stage 5 and then want to switch over, I will need to get a NEW clutch again.

your thoughts/suggestions are WELCOME

 

This topic is beat to death weekly, B16 will accelerate you the fastest granted you have traction to run high power and the redline to match, GSR is good all around because the gearing is longer, but will not make the car pull as hard, and if you stop making power prior to 9k its probably best for you with your power goals.

 

consider tire size and max rpm too when you are choosing your transmission as depending on what tire size and max rpm you are running will determine what mph per gear you are able to run

there are some really good gear ratio calculators out there that you can get an idea of what mph per gear you can get

once you have your powerband figured out you can then use the gear ratio calculator to pick the setup that works best for you to keep you consistently in the powerband you are capable of

 

Right now I redline at 8600rpm with a fully built head with supertech valvetrain. Would like to redline at 88-9000rpm next year.
