I just got an Si tranny for my 88 hatch.
I have a JDM 95 SOHC Vtec ZC, basically a D16z6 stamped ZC, and have been using the stock 5 speed DX tranny. I got a 90 Si tranny, clutch and flywheel, so all those parts are covered, but the guy I bought it from told me I had to change the axles, probably a hybrid axle that would fit the Si tranny and my DX wheel hubs, Is this true or will stock Dx work? Also I have some brand new axles from a 95 ex coupe. Will these work?
Thanks

 

i believe the dx works, its the bastard HF that don;t

 

yes they will be fine...

and YES the HF axles WILL fit into a Si and DX tranny...

 

oops! thats right, its the DX Si and b series axles that dont fit in the HF hubs, .. see why its a bastard.

 

Thanks, I have everything to do this now. The Si tranny is better for performance right? I hope to feel some difference.

 

yes the si tranny has shorter gears giving it quicker acceleration. but lower fuel economy because you run 3k rpm at 60mph instead of lie 2k w/ a dx / hf tranny.

 

WRONG

The DX and SI gears are EXACT it is the final drive thats different.. sowwy but fact.

 

Wait, I have an hf. So I could swap a dx or si tranny as long as I keep my hf axles?

Davcivic, will you be selling your dx tranny?

 

yep...

 

yup shadow rex is correct, ideally you want a dx tranny especially for freeway driving... the best tranny of all is the zc because it has the shortest gears and a longer final drive... ideal for the zippiest honda tranny youd want zc gears and si final drive.. for daily driving id just go with the dx because in a 1/4 mile race most likely u wony be hitting 5th gear anyways
