I have a y8 head, dizzy, and ecu, and want to put it on my y7 block. i know i need to change the iacv wires and add vtec wires, BUT im not sure about what to do with a knock sensor. The y8 and the D17's are the only SOHCs that use them. I was wondering if there was a way from me to trick the computer into making it think i have a knock sensor. Also, I dont have a throttle body, but im thinking i can use and sohc vtec or any b-series throttle body and it can work, is this correct? as long as it has the tps sensor on it? please let me know what i need to do, and if anyone knows of a link of somewhere that i can get a ecu pinout so i know where to remove and add wires i would appreciate it, i found one, but im not sure how reliable it is. every picture i find is of a p28 z6 head swap, i would really like a y8 swap

well first off just crossover to the darkside(obd1) and run a p28 the dont look for knock sensor. that will solve that prob. and as for the link here u go...http://www.jdmuniverse.com/forums/sh...ad.php?t=32971 that shoud tell you everthing.... good luck i amabout to do it to..i got the y8 head, mani, tb, jumper harness 0bd2b-obd1, and the p28 ecu. you also might wanna get the y8 tranny.

I dont have the extra money to get the p28, that link was very helpful though. thank you. im just wondering how to plug a knock sensor into the block and trick the computer now, any one know?

just a helpful link may not help at all...https://honda-tech.com/zerothread?id=735196

thats a really good link, thats the actuall y7 y8 swap... ive been looking for that... now if i could just find out what i need to do with a knock sensor... in that link he said he didnt need one, but i dont think vtec engages without it does it?

1.buy a knock sensor
2.Screw it into the already tapped hole in the block(im pretty sure y7&y8 blocks r identical besides the pistons)
3.Plug the one wire it has into the ecu.

DONE!

madpipr

thank you... all the information really helps... i guess i know what im doing this weekend... i will keep you posted

Hondata can remove the knock sensor in the ECU, or so I've heard

Althogh I'd recommend that way

can i use any sohc vtec throttle cable? as long as its on a manifold that sits the normal way instead of up and down like mine? will i need to change all the brackets too?

Syndacate

you may have to use just one bolt instead of 2 on the cable holder and move the bracket over one...but that should fit fine...same cable 'n all

so w/ O's being open holes and X's being filled hole, isntead of this:
__X___X___|

You'll have

_____X___| O

If that makes sense

tha_badguy

you can reuse ur old cable u just need the y8 bracket
thats what i did
only thing is that the cx cable is really long
so u gotta route it outta the way

madpipr

but as long as it lays long ways once i get it mounted its fine? its a 98 dx hatchback.... do you have a pic of the way yours is mounted?
