Which year should i use for my motor because I need to no how many splines or sumthing like that. I have a 99 LS motor with a GSR flywheel and stage 1 ACT clutch and i was wondering which year b16 tranny do I need for my car
I really need to no ASAP
thanks

 

Any B Series will bolt up to the 99, but what year car do you have?

 

i have a 90 civic hatch

 

Ok. You need a B Series Cable transmission.

You can use a J1, S1, Y1 or A1. They have different gear ratios, so it depends on what you are looking for with the car of what might be best.
The YS1 is a cable trans, has a different spline count than the ones above, but can be used.

If you are looking to re-use the clutch that is is on the 99 engine all ready, that would only be the YS1 cable trans that will work that is cable.

If you get another clutch, you can use the J1, S1, Y1 or A1 tranny.

 

ok so as long as i get a jdm b16 cable tranny I can still use my ACT stage 1 clutch from the LS tranny?

 

no you would need a 91-92 ls or 92-93 integra gsr cable tranny. the latter of the 2 is the ys1

 

but arnt there b16 ys1's? because I want shorter gear ratios too
