Advantages & Disadvantages of Turbo w/ B15 transmission.

[qfry]

something that the b15 guys with turbos are doing is putting a maxima final drive into their trannies (spec 6-speed only). it lets them go 100 in 3rd. heres one of the links http://myspecv.com/f/t13201.html . ive got an 05 spec v and am planning on doing this when it finally gets turboed and doing the same on my b13.

so what FD are you going to put in your B13


It would also seem easier to get a Maxima 6 speed box and just change the bellhousing to a B15 6 speed bellhousing.

the gear ratios in the maxima tranny with its final drive are way longer than the spec's but if you swap in the maxi's final drive you have a more balanced overall gear ratio plus the b15 has an lsd, im not sure if the maxi does. i plan on a spec v tranny and maxima fd.

The Maximas do come LSD also.

Do you realize that the Maxima tranny will be better suited for turbo because the gears themselves are longer

[Andreas Miko]

You did not answer my question, what FD are you putting in your B13 tranny

[Andreas Miko]

Ok I am going to quit with the crap.

A Maxima and the majority of B15 trannys have the same gears.

A Miko, sorry about not answering your ?? i miss read. i do plan on swapping my transmission so i would still have the same final drive in my b13 tranny. as far as the final transmission ratios the spread sheet i recieved from a friend at the dealership had different numbers, however i just finished searching everywhere and i apologize for the wrong info. thanks for the correction. and i did not know if the maxima had an lsd.

Nothing to apologies about brother, I am just having fun online and if you know me inperson you would be poking fun at me if you got a chance.

[qfry]

and the #1 reason i would just swap the b15 tranny final drive is that it would be easier to do and i already have a second spec v transmission.

fry

[qfry]

no problems, i just dont like being the person that puts out bad info.

its easier to change a belhousing than a diff. So you swap bellhousings and then you sell the left over tranny to a Maxima guy.
