I need some instructions on how to wire my D16Y8 to my 91 CRX SI . I'm keeping my A/C and i don't want to wire the VTEC to a toggle switch . i will be buying a VAFC if that helps matters .

 

You will need the VAFC to control the VTEC. Your best bet is to convert to OBDI, run a P28 or equal and run a Y8 map. Then screw the VAFC.

 

If i convert to OBD1 i will need an OBD1 dizzy as well right? is there instructions somewhere on how to do the rewire ( pin outs that need to be swapped and plugs that need to be changed ,stuff like that ) ?

 

Yes, and it depends on which OBD0 to OBD1 conversion harness you get that will determine how to wire your dizzy up.

Dave is right though, OBD1 and sell the VAFC is the best route.

 

Any suggestions on where to buy the conversion harness ?

 

see the guy above you there? wait till the banner on the bottom popups up with OBD Jumper harnesses...then you click it...should get you straight there!

 

I'm pretty sure he can wait a couple seconds...

 

Thanks , for the link .i'm going to switch to OBD1 when i can afford it ,I just want to get the engine in and working .For now I'm going to run it OBD0 w/ the VAFC . I have a friend who has done this successfully in a wagon ,so i have his help .
