b16b gearbox options

[vrmmmpshhh]

hi guys, bought my ek1 hatch a couple of weeks ago and already have a b16b package coming in a few days. engine package came minus a gearbox which puts me in a pretty good position to get a good setup going. any recommendations for gearboxes? i see plenty of ITR boxes around but ive been out of hondas for a decade now and have no idea if they are suited.

the car gets driven pretty hard and is replacing my turbocharged mx5 for gymkhana/touge

the gearbox that suit the civic ek9 b16b is gearbox that comes with

Should either try another b16b gearbox or build a gearbox with custom rotios
Could get by with just dc2r b18c gearbox

And you should spend the money before you install into your car rebuild the gearbox as most gearboes are high kms these days and people off load there crap as good used products
spend the money and saves you more money & time

rebuild a b16a2 s4c with stronger syncros and what not and put in a LSD

B16a S4C with a clutch type LSD (I recommend Kaaz) and maybe a shorter FD (4.7 or even 4.9) would be the perfect combo for the events you want to enter. If you still want to street it add a .714 LS 5th gear set to offset the high RPM cruise of the short FD. I've got most of these bits in stock if you're interested, except the gearbox. Check my trader pages here on ozhonda or my website for rebuild options.

awesome that sounds great. b16a gearboxes are well priced too.

Just rebuild your b16b gearbox if your going to go down the rebuild/refurbish path. If not a dc2r box would suit it well with the higher final drive, thats the one thing I wanted with my b16b, shorter ratios

Yeah sounds like op doesn't have a gearbox yet though? Late Dc2r S80 fetch a high price because of their factory helical LSD and 4.78 FD - s4c has same gear ratios but 4.4 final drive and are much cheaper especially if open diff. If you were going to overhaul it anyway, just get the cheaper box and fit better stuff in it (FD of choice, LSD of choice, new bearings seals and synchros). All dc2r boxes are at least 12 years old now and absolutely thrashed and need money spent on them anyway - Just my $0.02

i have no gearbox at the moment which is why i want to know what the best option would be. sounds like the dc2r s80 is a good option which i should be able to find under 2k.

Yep definitely a nice box. Just be aware that there are many s80 boxes and not all are out of the dc2r, not all have LSD and not all are 4.785 final drive. Only 1998-2001 dc2r gearboxes have the goodies. You want to verify you are getting the real deal before parting with the cash. Ideally you want to drive it in the car before you buy it to check synchros are ok, no noises etc. but most of the time this is not possible. You will be able to see straight through the diff where the driveshafts would go, with no pin crossing it if you're getting the factory (quaife) helical LSD. Short of ripping apart the gearbox there's no way of externally verifying you are getting the short final drive.

what do you guys think of a dc2 vtir box with a kazz lsd?

[dougie_504]

Sh!t gearbox for your engine IMO. Crap gear ratios.

Either get an ITR box, or get a B16A box.

Or get the VTiR box and change the final drive to something better like a OEM 4.7 or aftermarket 4.7/4.9. Unless you want something that cruises and doesn't accelerate fast.

Agreed. If you swapped the VTiR FD to a 4.78 or something you'd have an awesome box as the gear ratios are actually closer than the DC2R. It would be very pedestrian though if you kept the 4.4FD.
