LS trans vs B16 trans: how much quicker is it REALLY?
This is something I've wondered for a while. Having driven a Civic EX (which by the way has slightly longer gears even than an LS) I found myself wondering exactly how bad an LS transmission is for 1/4 mile times. Honestly my 1.6 single jingle with EX transmission didn't feel terribly long.
Compared to after I did my LS/VTEC swap, now I have 200whp with a B16 trans. I'm no stranger to the B16's super short gears and high RPM highway driving, but I find myself longing for the days that my eardrums weren't buzzing from 4.5k RPMs constantly.
Bottom line: Has anyone actually done a back-to-back LS vs B16 transmission 1/4 mile comparison? Same or at least similar engine/mods/car weight? How bad is the LS in the 1/4 mile REALLY?

Re: LS trans vs B16 trans: how much quicker is it REALLY?
Maybe it’s different because I’m in Canada we didn’t get an ex..but I was under the understanding that sohc ex trans had the same gears as a z6 si trans? Could easily be wrong...
LS trans will likely fall out of vtec between gears, b16 trans some ppl don’t like for 1/4 mile depending on your redline u might bounce off the limiter in 4th a few times on the big end or have to shift to 5th. A nice compromise is b16 trans with LS 5th for hwy

Now, I'm no drag racer, so I understand that you must not leave 4th gear, but as a matter of keeping the torque multiplier high, the LS 5th was a bad idea.
My impression is more detailed in my build I completed a few years ago. I went to a GS-R 5th gear.

Look in the stickies and I have a thread about gearing affects on the 1/4 mile. It is with a D series. AFAIK nobody else has done anything similar (and published it) with any engine. LS 5th is horrible in anything but an LS trans.
