thanks in advance

 

Do you have a DX ecu?

 

You need to make sure you have the DX ECU, the VX had an economy VTEC system, which means it had some of the associated sensors that the DX engine wouldn't have.

 

I know you're probably in a hurry, but punctuation would make it easier to understand you.

 

sorry about the punctuation but im am in a hurry and to tell you the very honest truth i have a problem with writing kinda like when it comes to complete sentence` s i cant make them they dont register in my Brain ...ever since grade school sorry if it buggs anyones else ...

.but on to my post what if i were to put my D15Z1 head on the DX block <-- that is where the extra plug is i think ....No i am not looking for more power due to the VTEC but i am tapped out of $$ and have no where else to turn ...i know all i would need is the Head gasket for the D15z1 head . I do not have the DX ECU maybe that is why it wont start
I called around and a Wiring harness for a 93 dx around here is 250 dollars from a junkyard <--thats the cheapest
i dont even wanna know what a ECU will cost me

Agian GUY`s thanks for the help
