B16A2 which gearbox

[eridzone]

Hi all

I recently bought an Integra DC2 Type R gearbox from 2000 model with 4.7FD, LSD and N3E is printed on housing.

currently i am running B16A2 with S4C gearbox.

I am a bit confused whether i should swap the S4C box or keep sticking with it.

I want to know whether it will be worthy to swap the gearbox because i have just checked(I forgot to see before buying) that both boxes have same 1-3 gears and actually S4C has shorter 4th and 5th gear than DC2R box.(may be i may have misunderstood the comparison details). Could someone explain these values?

S4C (JDM Civic SiR/ Type R)
1st gear Ratio 3.23
2nd gear Ratio 2.105
3rd gear Ratio 1.458
4th gear Ratio 1.107
5th gear Ratio 0.848
Final Drive Ratio 4.40


S80 (JDM Integra Type R 1998 2001)
1st gear Ratio 3.23
2nd gear Ratio 2.105
3rd gear Ratio 1.458
4th gear Ratio 1.034
5th gear Ratio 0.787
Final Drive Ratio 4.785

What is the use of dual synchros for every gear in this box? and Is LSD really helpful in real life street daily driving plus some aggressive weekend runs? 4.7FD does it mean that it will give significant gain in acceleration? Which one is shorter in terms of gearing 0.848 or 0.787? I only need better off the line acceleration.

and one last, do i need to change my drive shafts(i have B16A2 in EG 1994) the one which connect to diff not to hub and can i use my existing OEM stock clutch and flywheel or they are not compatible with DC2R gearbox? If i choose an after market Stage 2 or 3 clutch and lightweight flywheel, will that make the car accelerates faster and all of this combination i mean gearbox, clutch and flywheel could transfer more raw power on the ground or this will be just a light difference?

good choice but imo they're all rooted. Do a full rebuild before you use it.

currently i am running B16A2 with S4C gearbox.

swap it out for sure.

What is the use of dual synchros for every gear in this box? not sure but i would say they help you get into gear faster and Is LSD really helpful in real life street daily driving plus some aggressive weekend runs? LSD will help you get the power to the ground 4.7FD does it mean that it will give significant gain in acceleration? 4.7 FD is the main thing that is better than b16 bok Which one is shorter in terms of gearing 0.848 or 0.787? I only need better off the line acceleration. 0.848 you will rev higher in 5th gear

and one last, do i need to change my drive shafts(i have B16A2 in EG 1994) the one which connect to diff not to hub and can i use my existing OEM stock clutch and flywheel or they are not compatible with DC2R gearbox?

drive shafts should be ok, I would get changeover shafts.
while you're there, might as well upgrade your clutch. sure it'll be ok but gonna be a bit shit.

upgrade the fly and clutch won't make you go faster much but your driving experience will increase 10 fold.

Thanks mate

so you mean 0.848 will give higher acceleration at cost of high revs in S4C, so S80 is slower in 4th and 5th?.

No

S80 better in every aspect, because of 4.7FD

Only situation where s4c is better than s80 is big boost

They only have twin synchros on second. Twin synchros have nearly twice the surface area to slow the inertia of the gear set leading to smoother high rpm shifts. S80 for sure.
