D-Series Tranny Setup?
 

What would be the best D tranny for an NA build and a Boosted D?
Right now I have a 96-00 S40 K4F with the D16ZC 3rd and 4th Gears and an OBX LSD. Courtesy of sohcisme. Thanks man.
So this kinda makes it similar to the B-Series GSR Tranny...kinda
The Gear ratios on the tranny are:
1st 3.25
2nd 1.909
3rd 1.346
4th 1.033
5th 0.072
FD 4.25

My main question is do you think this tranny is suitable for both NA and a boosted D setup because right now my mini me is NA and feels great, but I was worried that if I added more power to the equation will I be wasting time shifting more often? Or does it really just depend on how much power it makes?

depends not only on how much power you make, but also how well you hook. if you're running at the track, and have big enough slicks to keep traction, i say the shorter the better to an extent

troof

i would like to add, the gearing you posted sound killer for a boosted setup

I know! 1st through 4th gears are magical for a NA D-series, and 5th is still extra long for saving gas. I've been saving for a while to get a decent kit, but everytime I get enough something comes up and I put off buying it yet.
I'll probably be getting her tuned by Locash within the next couple weeks once I put my new header/exhaust on. Should be decent numbers for a NA Mini-me.

you should be golden with that trans on a FI setup

I agree. For a boosted car, that 1st-4th should be perfect (depending on your choice of slicks). However, if you are going to come close to topping out 4th in the 1/4, go with a 92-95 DX 4.058 FD.

good as is for a FI setup.

As for N/A not so hawt.
the trans will be craving a aftermarket FD badly. exxo 4.7 possibly 4.9 would pull a premium before race wars.
