dpfi to mpfi

will a zc mpfi fit on a d15b2 or do i need a manifold off of a si

It will fit as long as it is for SOHC ZC.
I dont think that the DOHC ZC will work, but not totally sure...
Suppose to be better then the Si...
There may be differences with the vaccum and electrical connections.

ok thank u also when i convert to a mpfi what all will i need to make it work

theres a tutorial on http://www.fourthgenhatch.com
