Is there a rear-end gear ratio thread?
I want to change the ratio on my 1.5JZ car and haven't been able to find a thread that lists all the possible ring and pinion ratios available (300/400 auto and manual). My car currently has a Chaser R154 tranny and 99 SC400 Auto ring and pinion and needless to say it a highway SCREAMER. By the time the PTB76 turbo spools I'm doubling the speed limit so I want to lower the ratio (or raise it depending on how you look at it) while I'm having my TRD LSD installed. I need shorter gears to get this hair dryer spinning
Thanks.
Thanks.

I have attached a gear ratio calculator that might help you once you figure which diff you decide to go with. All you need to do is plug in the diff ratio and the gearing (find on wiki) and it will automatically calculate the speeds for each gear.
