question? if i just wanna swap my dpfi to mpfi with non-vtec throttle body is it hard cause i am prolly getting a parts car but its not an si model just a dx i belive. so is it hard to swap throttle bodies to my 91civic cx? all have all the stuff to swap off a runnign car so what will i need to make more power with the parts cars motor to mine?

 

Both of your questions makes no sense. Please rephrase that.

 

im sorry i was quite tired last night. i wanna know if theres a thread or sumthing out there to show me ho to convert my dpfi motor to mpfi if i have my parts car for it, its also a non vtec swap.

 

someone already posted a link above, but here's another good link for dpfi to mpfi info.

I just did the dpfi to mpfi swap with a d16z6 but found out laiter the write up i used was for a dohc zc did i mess it all up? it runs now but has a miss and wont rev past 3k. ANY ONE able to help me??

 

Yeah your car is now in limp mode so it wont damage its self.. there could be 1 of 2 things wrong here either u have a bad injector or wire is not giving the injector power or your crank position sensor is fualty... thats all i know about the cars ecu putting its self in limp mode and not going past 3k

 

which 2 ports on the p28 ecu do you jump to read the codes???

 

Ok on EFs there is a light inside the ecu but since your car is swaped and your using the p28 there is a plug either under/behind the glove box that u can jump with a paper clip an then turn car to the #2 ignition spot and the check engine light will flash corisponding the code number there is a link somewhere on honda tech that tells u the correct way and codes to do it!
