Wanted to know your all's opinion on best transmissions for boost. Currently I Have a b16a with an LS trans

 

GSR.

 

Boost is irrelevant. All that matters is the power to the wheels and the intent of the car.

ZealAutoworks has a good online calculator for comparing transmission ratios.

Every time I hear someone using a B16 with an LS trans (especially all motor) I cry a little on the inside.

 

Chance EG, so you are saying "One that doesn't grind is best", right ?!?
On the B16/LS combination... I feel your pain.

 

Not for "K" series... someone needs to update that for realz. They got the "B" stuff on lock down doe, so the OP should be set to figure out his/her exact needs.

 

You can still input your own gear ratios bruh.

 

 

Of course... but I ain't got no time for dat !!! They should be in the pull down menu bruh.

 

Quick release steering wheels, and quick release gear ratio tables

Edit: Bruh.

 

Co-Sign. You have to state the purpose of the car. Different purposes and uses require different behaviours coming from the engine & turbocharger setup. There's no one-size-fits-all, but there are better transmissions to start with, then you can tailor the gearing behaviours to your needs. Be mindful, in many areas of the U.S. good transmissions are hard to find. If you transmission runs quite well, it may be in your best interest to simply change the needed gear sets/final drives, etc rather than to risk purchasing a "bad" transmission from somewhere else, parties unknown.

Think about what you currently have, and use the enclosed calculator to see if perhaps only certain things need changing, or whether a different transmission type altogether is needed. These tools will provide the best assistance. You can then ask opinions of others based upon their purpose of their use, (taking into account the size and purpose of their turbocharged build) and see if they contain similar behaviours as to those that you're looking for, rather than asking blindly "what is best"..

The real question to ask is "What is best for you".





MFactory Transmission / Final Drive / Torque Multiplyer calculator

 

Use the calculators as the other members have suggested based upon your requirements, use of car, max rpm etc. To give you an example I made the switch from a LS trans to a B16A with 4.400 FD and picked up around a 0.5 second in my 1/4 mile time without other changes however when I started adding more power into the equation the B16 with 4.4 FD was too short taking into account my car's rpm limit, power and tyre size which resulted in me hitting the rev limiter before the line. In the end I settled on the following combo B16A 1st to 3rd, GSR 4th, B16 5th and 4.266 FD.

Its all about your setup and what you need it to do, what your limitations are etc. A B16A trans does make the car accelerate faster than the LS, at the expense of mph and highway fuel economy if you concerned about that, but it can pose a problem if you need more mph like I explained above or if you doing roll racing etc.
