si engine into an auto dx

ok sellin an auto dx to a guy and he wants to put his si engine in it...i told him i'll give him a dpfi manifold so he can use it.....anyone see a problem happening from this...someone said that i'll have to use an auto manifold...is this true?

only thing you will really have to do is take out the old DX engine, install the new SI engine ... im not entirely sure if it will work correctly with DPFI but my sock zc did and thats supposed to be run with mpfi, i think it depends more on the ECU ... then hook up the tranny which should be fine.


honestly though i am mostly assuming i know its right ... but i could be wrong.

well....i told him what i had and what he's gettin...so the rest is up to him
