Two things i would be doing,
Race the local Cars Here
And Daily Driving
Which of these trannys would be best without wasting a lot of gas?

 

gsr, but id rather get a b16 tranny

 

If the B16 is stock with just bolt ons, get a B16 trans....

 

maybe stupid answer here but wouldnt a type R tranny be best??

 

Thanks for all your answers, specially the ones that didn't argue
It's my first B series swap so I don't know much,if anyone has done a b series into a ek can you guys help me out I have some questions I dot understand and I don't wanna keep posting so pls PM and we can text to make things easier thanks!

 

b16 or type r (usdm r has the same gear ratios as the b16)

 

GSR is going to have better ratios for racing, while LS is going to save you gas on your commute. They weigh themselves out you just have to pick which is more important to you.

 

Actually you use more fuel in a B16 with a LS trans.

 

ls tranny has longer gear ratios and the gsr would be good you would use less fuel but you would notice a big difference in the final drive of the gsr

 

I would go B16 with LS 5th gear set to help keep RPMs down at highway speeds since you are concerned with fuel economy.

Or if you can swing it...Type R since it comes with a factory Limited Slip Differential and add the LS 5th gear set.

 

On a b16a you need all the gearing help you can get. B16a/R gears ftw.

 

anyone selling a ls tranny. pm .. i drive about 80miles a day on the highway and b16 tranny is killing me in gas.. i need this ls tranny asap

 

You'll get better economy with a B16 trans than you will a GSR, LS, or B16 with LS 5th.

For the average driver with current gas prices it will take a couple of years for a trans swap or 5th gear swap to pay for itself in fuel savings.

Just an FYI.

 

Please explain this theory in depth.

 

Higher RPM = less throttle needed to keep it moving. Less throttle = less fuel used.
