Default Making H tranny as Competitive as H2b

So i got to thinking recently, the b tranny works so well on the H. Transferring power wise.
What exactly gives it the extra OOMPH compared to the h trannies?
Is it the Gear Ratios or the bigger Final Drive
If it's the final drive then just getting Mfactory 4.66 FD would make it more competitive no??
Or is it the Gear ratio.

Both.

You can build a close ratio H trans with stock FD and be better off than the B trans. The only problem with the H trans is shifting, but there are easy ways to fix that.

What ways are there to make shifting easier and have a tighter shifter feel/shorter throw. I know theres the "short shift" adapter for the cables but a 2 friends of mine have used it and have either stretched their shift linkage cables or have broken the cables.

Cheaper to just switch to a shorter FD. It will work wonders.

actually a shorter FD wont do much, especially compared to a b series trans.

you will never get an h trans comprable to a b trans, its just not gonna happen and believbe me i have tried. eventually i accepted the fact and switched to a b series trans and wish i had done it 8 years earlier.

in stock form the b16 trans knocks .5 off your et and gives you 20whp more (dynojet). not to mention you can start shifting it WOT and it knocks off 1-2 more tenths off your et.

even a properly tied and fastened h cable shift linkage doesnt even come close to a solid b linkage, two completely different feelings in your hand.

the b trans has alot less drivetrain loss inside the trans itself which you will never duplicate w/ the h trans. this helps to achieve that 20whp gain...

b trans in a civic chassis the axles are straight compared to the h trans being angled, this also helps achieve the 20whp difference.

and finally the gearing is completely different, this plays a large role in the extra 20whp that the b trans has over the h.

the FD plays a very small part in overall performance when your comparing it to the actuall gearing itself.

if you want to switch to a b trans then get rid of the prelude and do it in a civic. i know someone who did it in a prelude and it didnt work out to well lol.

if your keeping the lude than the best thing you can do is get a dogbox w/ different gearing if its a drag car. if its a street car then the only thing i would suggest is upgrading to a twin disk clutch and your shifting will greatly improve. other than that you just have to live w/ it....

i used to own a lude a long time ago, i loved it. but its simply not a great choice for drag racing so i had to let it go

Its like dynoing a FWD car before and after an alignment. Optimal axle and suspension geometry net more power down to the ground.

And this pretty much says the same as to putting an H tranny in a Civic/CRX/Integra chassis. It can work, but unless its just right your holding on to a little bit more.

My experience is very limited(read none) in this field. But have you ever tried the 5.2 FD for the H trans competitively? Or do you think it would not make much of an impact as well?
