ok. took my skunk 2 manifold and bbk 62mm tb off. Killed my low end, gave a couple more mph but that about it.

Picked up a z6 head, mani and tb. Have my y8 head on my y8 block with the z6 tb. Read in here https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/will-z6-throttle-body-work-y8-manifold-1025068/ that they z6 throttle body is the same as the y8 throttle body. Is this the case? Do I have to switch anything from a y8 tb(which I dont have) to the z6 tb? Are all the vacuum, hoses the same on both?

Can I put a breather filter on the hose that runs from the top left on my vc? Where would I cap the end of that hose at? I forgot where all the hoses go but I can search for a picture.

Is there a thread that tells/shows all the ports and where the hoses and stuff go? I pulled the stuff off in the dark since I had a sale off craigslist.

How is the z6 head compared to a y8 head? I've read there is no vtec on the z6..can it be tapped for it?

I have a Hondata blue heat gasket. Will that suffice or do I need a new gasket?

Boost is the next goal. Am sourcing a turbo but am unsure as to what direction to go. LOoking for about 8-10lbs of boost and this is a project.

Any advice is appreciated.

Find a field service manual online.
Z6 is a VTEC head.
Don't know why you just don't get everything stock to the Y8 and not mismatch parts. It'll save you some headaches and work.
PSI doesn't mean anything. It indicates nothing.

Having issues finding a y8 throttle body. Only reason I got what I got.

I have a service manual.

Edit: The guy I got the head from told me it was a non vtec head but I was thinking it had vtec. I saw what looked like a port last night. Even with vtec, I'm thinking the y8 is a better head? What about for boost?

Then you should see how hoses are routed. You'll need to remove and block off that FITV.

I'm working on finding it in the service manual but have no idea where to look. I'm searching tho.

The fitv is on the z6 tb, correct?

grumblemarc

iTrader: (4)

Yes. And I'm not sure on the wiring on the IACV on those either.
There are Y8 TBs on Ebay for cheap.

dseriesboulder

Might just go that route and build the z6 when i find a block.

Found a y8 throttle body. Wish I never sold the one i had..lol

Ok. I'm kinda stuck. Have a couple of lines I cant get routed.

First port- The one coming off the fitv. I heard I can just leave this one uncapped since its basically a switch.

The small coolant plug next to the big one on the block. Right below the tb.

I have the plug on top of the tb capped as well as cruise.

next, their are 2 ports on the front of the mani. top and bottom. I have the bottom one going to the sensor on my fuel rail but do not know what goes on the top.

I have a hose in the back but its to short to run to anything. I have seen illustrations about a hose running thru the IM runners, does this happen to be the one?>?

I have searched but can not find a good description or picture of what I'm tslking about. The service manual I have I cant read so unless someone wants to tell me what section the vacumn routes and the coolant hoses are........

Any help is much appreciated.

Me and the wife are splitting so I need this at least driveable.

Car does start, idles high, does not kill over.

I'm using a y8 gasket on the z6 throttle body so thsts probably not right..lol

Pics would help tremendously

Give me a few.

Edit: Are all z6 heads vtec? This one is only 12 valve.(everything is on a y8,,just wandering about an extra head i have.

Coolant plug by main coolant plug



Capped off port on top of tb


Sensor off fuel rail


Port above port for fuel rail


Cruise


FITV

I have a z6 manifol as well if that would help. I just need help with the hoses. I know you guys know. The z6 throttle body is a direct replacement of the y8.

Someone help me out.

Why do you still have the FITV on it?

dseriesboulder

iTrader: (1)

Because I dont have a block off plate and I heard it can stay on. guess not?


I have it looking like stock right now. Idels high. All the vacums are int he right place. I still have that untapped coolant port, a port on top on the tb, the fitv and cruise is capped also.

so i need to take the fitv off and put a block off plate there or can i use gasket maker, put a seal there and call it good? what about the coolant port and the one on top of the throttle body? cap both?

Edit: My z6 head is 16 valve so disregard that other question further up.

Could I use a gsr throttle body?

waynesumner

you can block off all tubes on throttle body and where the tubes come from. run the left side tube from iacv on back of manifold to connecting pipe under intake manifold and cap off small nipple on intake manifold run big nipple as normal and right side of iacv to other side of connecting pipe. the connections on throttle body the top one is for vaccum purge the bottom one is for coolant and fitv is for coolant so you can block them off and it will be fine. also you can google images of coolant diagrams to get the right way to hook all lines up. I would post one but my computer is acting up.

dseriesboulder

iTrader: (1)

Thanks for that. Do I cap the coolant connector next to my main coolant connector on my block?

I still use the iacv from the y8, correct? And block off the fitv? Just making sure j got it for sure.lol

waynesumner

yea block off fitv and I think the main coolant line on the block should not be plugged I will have to look at mine for reassurance but as long as it is connected to some kind of coolant line it should be ok I will try and get an image posted for you of how mine is.

Aren't you the guy that dumped like $700 into a AUTOMATIC Y8 and had it go to crap? You been trying to fix it ever since. Go all back to stock IMO and research before your next attempt at this type of stuff

dseriesboulder

iTrader: (1)

I'm talking about the port next to the one on the block.

Yes I am. I'm technically going back to stock. I never had to fix it once it got back to me. It just didnt drive like I thought it was supposed to. But it ran, ran good and I neeed the cash so I had to sell what i could sell.

I'm going back to stock for the sake of boosting in the near future.


Edit: Will be picking up a y8 throttle body this weekend but i need the car running by before then..lol

I'm gonna block off the fitv when i get home...dont know how yet but ill find something. Dont have the cash for gasket maker so we will see what happens. lol

dseriesboulder

iTrader: (1)

Someone is gonna say something, but screw it.

i put hondabond in every port on the fitv. like, its sealed. getting gasket maker(found out after the fact) and gonna still seal it off with it.

The coolant T off the main coolant off the block, how do i splice in to that and do a T? Whats supposed to hook up? I have no fittings on my IAC. Could I cap it?

grumblemarc

iTrader: (4)

I'll be first.
You couldn't make a block off plate? If you didn't want to buy one you could have just fabbed one up. Way to half *** it.

You shouldn't have to be splicing into anything.

dseriesboulder

iTrader: (1)

then where does this connector connect to? From what I've read, it's supposed to connect to the IAC? I know mine had the 2 coolant connectors but those are long gone.

And i'm making a gasket to cover all the holes on the FITV to seal it good. Thats what happened with my BBK when installed and it worked.lol

Sorry if it id half ***, I didn't need the car when I started this, was gonna do it right, but I need it at least drivable by friday morning.

Also, I've read some forums, and it seems like I can use the gsr throttle body is I take the spring off the y8(or a z6 i guess) and get them port matched.

Any experience with this from anyone? I have a complete GSR minus the MAP. i have a map. Would I just make a block off plate for its fitv and call it good? Use a y8 gasket?

dseriesboulder

iTrader: (1)

Ok. I made the loop with the coolant line, made a gasket to cover the fitv and it cranks on first start. idles high and ill fix that soon. But i have an issue.

When I removed my fuel rail the other day, an injector fell off. Its the one closest to the driver side. Now I have an air leak all around it. Is here some sort of o ring or something that could of fell? It looser then all the other ones and its the only one that fell. the others were pushed out but didnt fall.
