ok well i originaly had a d16a6 and it got stollen and i found a d16y7 laying around the shop so its what i want to slap on there
the block is a d16a6
so i was wondering if you guys could help me on a parts list on what i need for the swap
the car is 89 CRX si
obd0

 

just swap in the y7 long block and use everything from the a6. mounts including t-belt mount, intake manifold, exhaust, harness, and ecu.

bing bang boom. that's how babies are made

 

Yup use a6 intake and exhaust manis and all a6/b2 mounts

Shave your timing gear cover a little. Gl I have a y7 with a6 **** in my civic

Anyother. Questions just ask

 

ok my fault for being an utter moron i forgot to leave out a vital word "head"
i just need to swap a y7 head onto a A6 block ;P

oops

 

Lol :goggle: y7 head on a6 block

 

remove the oil restrictor out of the y7 head, use a6 head studs. Im not 100% on what cam gear to use, or if the distributor aligns properly.

There might be better write ups on this on d-series.org

 

Dizzy will bolt up I'm using a a6 dizzy on a y7 and I think you need to use the a6 cam gear not 100%

 

oil restrictor??
all ive found is this and it made me pray i get this right

 

the y7 head will have an oil restrictor located in the upper center of the deck surface,

the restrictor is on the A6 block ,

having two restrictors is bad.

 

does anyone know what tming belt i have to use
i heard it has to be 105 teeth....

 

the problem with all this and none of you seem to notice is that the y7 head uses a different intake mainifold the a6 one will not bolt up to it
if you want to use a y7 head you'll need a d16y7 intake mainifold

and you use the y7 timing belt with the y7 head

 

I'm using a a6 manifold and dizzy on my y7

 

are you sure on the t-belt
and the a6 intake bolts up fine ;P but either way i have to get the y7 one cuz the intake was on the head when they stole it

 

DON'T get a y7 one it won't work unless you switch a few thing on the throttle body and its a pos intake

Go with a a6 z6 or y8 or skunk2 d series intake don't waste your time trying to make the y7 work

 

Also I think you need to mix/match y7 and a6 headstuds, I know you do for z6's

 

alright thnx for the input
so im guessing i have to get a different head
i dont get if the y7 is suposed to be like the y8 but without vtec whys it a pain in the ***

 

Well okey so I blew my y7 up for the 5th time I am currently swapping it to a d16a6 I know one is obo0 n once obd2 what will I need to do to be able to run it on my obo2.set up I really need advice

 

hey there where did the breather box hose From d16y7 go when you swapped everything over??

 

There was another post recently kinda similar but Pretty sure you need the Y7 timing belt 104 teeth as Marcos said, compare to the a6 which is 107. Also you'd use the Y7 gear so it matches the cam not a a6. The crank pulley from the y7 might be needed aswell.

 

What about the Breather Box hose where does that connect?

 

If all your other lines are hooked up and it's a extra, you can hook it up to a catch can.
