Im slowly gathering parts to take on this task, i have a y8 mani from a auto eg, and injectors with the plugs, can i use those and not have to worry about finding a set of si injectors and plugs, plus is there a write up or can some one tell me everything i need for this i know i need a pm6 and a resister box, im just putting the main on my stock d15b, the more pics the better as this is the first time im taking a crack at this and im trying to get it all done in 1 to 2 days at most

 

This has been covered a bunch; the FAQ's are your BEST friend on here.

google search dpfi to mpfi, you will certainly find what you're looking for.

yes you can use those injectors, just do a resistor box delete.

 

i know about all the threads on here but no ones covered using a y8 im on a b2,i saw on one site that i need to grind down a nipple on the head so the im will sit flush, and do i have to use an si throttle cable or can i just use the stock dx cable

 

u can use the stock one but it tends to stick alot thats what ive been told im in the middle of my conversion right now so i wud take the timer and money to get an mpfi one i will be thats the only thing i need to get i forgot to get it before i started lol. i used the z6 so i dotn really have the info for the y8 but i am also doing it for the first time. but dont u need 0bd-0 injectors? to run with and obd-0 ecu idk for sure

 

"i have a y8 mani from a auto"

GL with that.
You will need to find a 2 wire EACV (IACV) mounted to a throttle body.

 

DX cable will work, but you will have to make a large loop with the extra cable.

Either cable requires you to do something special to get it to work with the throttle body.
You can just flip the stock Y8 bracket over and it will work with minimal modification. It's kind of cheesy looking, but it works.
Cleaner install uses 85-87 d15a3 (civic/crx si) bracket with a little tweaking.
