has anyone tried to fit a B16 series tranny (Civic Si) to a B18C engine?

I was told not only will it fit, but it would be flying if i got it on there.
Is that true?

 

yea thats true...pulls harder cause of the shorter gears on the b16 tranny...i had it on the b18c...had faster acceleration but uses more gas

 

yes all B series tranny's are interchangable. and yes it has shorter gears than a GSR tranny

 

i just talked to a technician at one of these tech shops and he said he's gone through 3 B16 trannies after putting it onto a B18 block.

Would a differential help? Would a type R tranny work better?

any thoughts?

 

The technician was smoking something. B series trans are B series trans. They are interchangeable

I'd take a Type R over the B16 for the LSD but the B16 is definetly a nice tranny for an N/A car....

The B16 tranny housing is identical to that of a b18 tranny housing Bolts right up! Go for it!

yes a type R tranny will work better because it has LSD and shorter gear ratio.. however, on the b16 tranny with b18c, u will get better acceleration but on the freeway you wont be as fast as a GSR tranny

The JDM 96 spec ITR, all CTRs, and all USDM ITRs all pretty much have the same gear ratios as the cable YS1 B16A transmission and the Y21 hydro B16A trannies. it's the LSD that is the real advantage.

 

the cable YS1 has a shorter 1st and 2nd

the ITR's and CTR's mentioned above are the same as the hydro b16 in ratio

the newer jdm ITR's have a longer gear set but a super short f/d 4.785

the major difference between the ITR and the b16 (and other tranny's) are the main and counter shafts. they're different diameters and if you want to use an ATS gearset you'll have to swap ITR shafts into your case. most ats products are made for an ITR trans.

you can get an LSD in almost every b-series trans made from the factory. it was an option in other countries (so if you're getting a "jdm" trans, you could look for one with an LSD).

like everyone else said though, it will bolt strait up. the b16 transmission has overall shorter gear ratios (more acceleration). b16 hydro tranny's are just as strong as any other b-series hydro tranny. to say that the b16 tranny is going to blow up cause its on a b18c is just ridiculous. the dude who was blowing up tranny's was blowing tranny's for a different reason... probably because he drove like a jackass and didn't take car of his transmission.

 

NASCAR WOOOOOOOOOOOOOOOOOooo

That has to be the funniest location I've seen on here

 

ok - so the B16 tranny will fit and will work well with a B18 block. Hopefully no problems down the road because of the different gear tranny ratios (B18 vs B16)

how about the differential? - is that needed on a B18 block and a B16 tranny?

In terms of down the road repairs (regardless of cost - even though type R trannys are hard to find) what's better:

a B16 tranny with a differential or a Type R tranny?

 

All transmissions have differentials, there are open differentials and limited slip differentials.

The B16A transmission and the ITR transmission are seriously the same thing. It all depends on the condition of them.

If you had a B16A transmission with an aftermarket LSD like a Quaife, Cusco, ATS, or KAAZ, it would be superior to the ITR tansmission, but those LSD's retail for over $900 a pop.

If both transmissions have the same OEM LSD in them, they are equal. Repairs and maintainance would be the same.

lol, so i take it u have topped out 5th gear in a GSR? doubtful. i just put in a type r tranny in my GSR, and even if it was possible for my car to get all the air out of the way my gearing could take me up to 150. yes a GSR is higher than that. but u still want be able to get the car going anyfaster cause the car will be aerodynamicly limited prior. a type-r/b16 will make a GSR accelerate faster and be able to "go faster" then a GSR with a stock tranny. with a shorter 5th gear your getting more torque than u would be with a GSR tranny. thats all there is to it. and either way anybody topping out 5th on a freeway is a complete idiot.

 

If you get the 99-00 Civic Si tranny, I'm pretty sure they are LSD equipped from the factory, because my friend snapped her axle, and drove it home, then drove it around for two weeks while she saved up for a new axle. I know you can't do that with an open diff trans (I've snapped two axles). But I think you can with a LSD. So I think the 99-00 Si trannies are LSD. Someone please correct me if I'm wrong, or missing something

if i recall correctly, the b16 diff is smaller than the ones in the GSR or ITR. that might have something to do with it

 

anyone know for sure that the Civic Si tranny is LSD equipped?

In terms of the axles
Do the automatic tranny axles have to be replaced or can i use the same ones with a manual tranny?

 

99-00 civic Si trannys DO NOT have an LSD.
