Will a K20a2 trans bolt up to a K20a3 engine?? I think it will but I'm not sure.

 

yes

 

Good to know.

 

yes

 

what is even crazier that you can just add 6th gear to your current tranny. Cases and parts are identical (gearing is different ratios)

That is interesting, but at the same time, it is not as simple as adding an extra gear, just as you say about the different ratio's

A 5 speed shares the same 1st and 5th gear, as the 6sp uses for it's 1st and 6th gear. So really, you are buying another 2nd, 3rd, 5th and 5th.......sounds like it's not worth it to me.

There are some great deals out there on k tranny's out there now. For the time and money, i think your better off just buying another whole tranny ready to go.

I picked up an 09 Si 6 speed tranny w/lsd last fall for $700 with only 15K original on it. Hard to beat a deal like that when comparing modifying a stock 5 speed with whatever kms

 

Mines a 6 speed out of an 04 type-s. An thanx!!

 

but the z3 trans are not a direct swap

 

Ok but its an a3 not a z3

 

My bad an a2 trans!! It's a K20a3 motor!

 

Or are you just saying the z3 isn't a direct swap? Lol
