Look in the FAQ at the top of the thread directory.

 

You are using the stock harness correct? The wiring differences are as follows:

-injectors, use the SI for plug and play
-if you use the P28 ecu and go obd1 you'll need the D15b/d16z6 distributor and an adapter harness or need to repon the dizzy
-fan switch wiring from the back of the block to the new motors thermostat housing
-the fast idle on the back of the Si motor will not be used anymore
-wire up 4 wire 02
-vtec solenoid and vtec pressure switch wiring

 

yea i can comprehend som what but i need a list on what to do and what i need to get new so ty for the anyfo anmore would be great.. im just ganna either send this motor back or sell this hole package

 

Its pretty simple. Just take the intake manifold off the eninge that ur replacing. Then put it on the replacement engine. Then ull have to modify ur distributor a lil for it to fit. Google "a6 dizzy on a z6 head" and u will find pics detailing the procedure

 

wow ef your the only one so far who has givin me a straight answer ty

 

did you figure it out yet?... im new to honda tech but i have done b20s, ls, and many singlecams vtec and non...if you have the si wire harness off the car u still will have to wire up vtec still... and have to get a new ecu if u want vtec... u can use the same intake like efjones said and you will have to go into ur ecu harness to pin out vtec, you can find the vtec pinouts on google images... message me if u have anymore qwestions

 

It sounds like you got into this motor by accident? Am i right? And what motor exactly did you get? Pics?

 

this swap is easy i did a z6 swap in my 89 ef twice you gota know first if your goin to go obd1 or keep it obd0 then you will know what exactly u need to modify like dizzy, injectors, or ecu hit me up if u need help and u have to also change your driver side mount depending what car that motor was in
