Please tell me everything I would have to do to swap a d16y8 vtec in my 89 civic si, i am going to use my si tranny,
do i need to convert obd0 to obd1?

 

you will need to convert to obd1 for vtec to work

you will just need to bolt your tranny up to it

use a jumper for dizzy and ecu (p28)

wire up vtec

 

thank you.. what about the injectors? should i use the si?

 

You can use either your stock Si injectors or the Y8 injectors.
The only difference being that if you chose to use the Y8 ones then you will have to do an injector resistor box delete.

 

ok so its better to use my si injectors right? how about the alternator, si or y8? or does it matter

 

Have you even looked at anything you are trying to do?

Look up saturated vs. peak and hold injectors... You tell me what suits your application. Obviously using the stock injectors would be easier...

Obviously the alternator plugs are different... So use your A6 one. You need to search better all these answers can be found in the FAQs...

 

I would use the Y8 injectors because they are newer, but that's just me.
Using your Si ones will not make a difference as far as operation goes.

You can use either alternator, but you will need an adapter (or get the appropriate plug and wire it in yourself) to get the Y8 one to work.

alright thanks and im new to this site so thanks for helping me out people...

 

lol why you such a jerk, you didnt have to reply or post on this thread but thanks anyways jerk

 

You just read it wrong

 

^lulz

 

but anyways thanks 4dref, you helped alot i have another question what type of flywheel should i use?

 

Thanks for yet again making me laugh 4drEF...

Matching your transmission is usually the best route to go...

 

hey sorry im a little confused can some1 please help out, my car is obd0 and the d16y8 i got off a 99 civic ex and some people told me to convert it to obd1 but others say that the 99 civic ex is a obd2.....should i still convert obd0 to obd1? idk im a newb, so confused

 

You can convert to obd1 best thing to do u just need a 92-95 dizzy and ecu p28 and jumpers for both rywire has everything u need check out that link that was provided

 

how about i get the adapter for the dizzy on the y8? would it work

 

and if i have to get a 92-95 dizzy do i need it to come off vtec or does it matter?

 

i have a p28 but its auto, i seen online to convert it to manual just take out resistor 17 and 18 and put a jumper across 18, is that correct? but i also seen some1 that took off the transistor for ic15 and 16? but every1 online just say to take off the 2 resistors?

 

dizzy just has to fit the head idk wich one will

you cant use the y8 dizzy unless you convert to obd2 witch is a waste of time

and the auto thing idk

 

use the y8 dizzy and convert the dizzy plugs to the obd2 plug. that's it.

clutch and fly will match your transmission

here's how to convert auto to manual ecu conversion

yeah my y8 is the complete long block, and the ecu is from the same car, so if i just get the adapter it should work? what about the intake manifold should i use the si or y8?

 

id go with the y8

 

can i use my obd0 alternator on the y8 or i have to buy an adapter for the y8?

 

What I did was swap alternator pulleys so u don't have to use a adapter saves some $

Edit

I used the obd0

 

thanks king u been alot of help
