the civic is 89 dx dpfi i have a head that from crx si 89 thats mpfi

 

Yeah..That head will bolt right to the block..Just to let you know they are the same heads besides cam,intake manifold,and distributor..

 

so should i just put them parts on or the whole head

you can just bolt on the MPFI manifold and distributor; use the Si computer and then drop in the D16a6 cam but you'll need to phase the cam out a few degrees. I dont remember if its advanced or retarded but it is off slightly

 

even if you just use the computer and the intake manifold (switch to mpfi) you will notice a nice power gain... you can always throw in the cam later but if your gona go through all that i would have the d16 head milled and throw that on to get more compression... my .02

 

do u mean the si ecu

yes hes talking about the si ecu, you would need a mpfi ecu to convert (like one from a si), your dx ecu wont work.
if you need a si pm6, i have one for sale, pm me if interested.
