D To B Series Tranny Swap
 

Searched this forum and others, doesn’t look like this is a topic nor model used much anymore.

However, I figured I’d ask the community.

Civic is- EG8 with D15B7

I'm looking for a lower final ratio then the p20/b trans.

I have p20/a gives me a 4.058

I know the p20/b bolts up and gives a 4.250 (highest offered for my 5th gen)

I'm wondering if the 96+ S80 -w- LSD will bolt up to the D15b7 to give a final of 4.785

If not; Im open to other options.

So spill the beans already.

$800.00 for the kit alone is not lucrative for me. D series trans are less than 200$ if i can lock it up and upgrade the gearing I might as well do the p20/b. Debating between the .750 and .705 5th gear any other ideas?

what i see on the web is the clutch kit, are you looking to swap out the final drive gear?

i was under the impression that you couldnt swap a B tranny on a D motor and vise versa

Bisi does make d to b kits but are only useful if you have a ridiculous D series that mating a b series would benefit you.

quick question i dont know much bout hondas but will a d16 trans bolt up to a d15 motor? please let me know and also would i need to get a new clutch kit it i swapped them?

Yes it will bolt up.

New kit is always good idea.

thank you very much... i appreciate the feedback
