how much of a difference would i be able to notice if i swap out my d15 for a d16? alot, or a little?

 

1. You will need to convert to mpfi before you swap the engine.
2. You need to tell use which d16 you will be using, that would help a lot.
Example: d16y8, d16z6, d16a6, d16a8, zc?
3. Get an '90-'91 si transmission.

You will notice a big difference between you d15b2 with long gear ratios and a d16z6 with short gear ratios (14s in 1/4 mile).

 

hey thanx for the reply. that helps, especially the 1/4 mile info that what i was really looking for. my friend crashed his civic. i think its a 97 but im not sure ill ask him. is it hard to switch to mpfi and is the 90-91 tranny a cable or hydro? my friend is selling me the engine for 300 so after the enging how much am i looking at for the full complete swap?
