Different Trannies

I have a friend with a 90 civic dx hatch and he just swapped in a dohc zc but still has his dx tranny. I drove his car and it is not as quick as my car and I am just wondering, if he gets an Si tranny how much quicker will it be? Oh yeah and I do know he has the ZC (pm7 i believe) ecu.

dude if he has a DOHC ZC hatch and you have a SOHC ZC 4 door, and your car is faster, his engine is super shitty.

The DX tranny aint *that* bad in the scheme of things, just a tad bit under the Si in performance..

lol well it did get flooded i think or somehow got in the water and right now his car is in his garage till he gets some new rod bearings.
