Im using....

99-00 y8 Intake Manifold (i already got the extra holes screwed in and covered)
y8 gasket
Integra LS Throttle Body (using gasket maker instead of the ls gasket hope its ok )
z6 IACV
z6 FTIV

my problem : THERE ARE no leaks, no hissing, no cels coming from my motor...all it does it idle between 1,500-2,500 CONSTANTLY!

I tried : replacing my FTIV are still no sign of luck...cleaned it, screwed it back in...still revs like ****. I also tried putting back on my stock z6 throttle body and still the same problem occurs. Im thinking its the z6 IACV...because my friend and I are using the same setup on our motors EXCEPT he has the y8 IACV on his.

I dont know whats wrong help me! IM DYING!

 

ttt

 

HELP ME IM DYING!

 

the 99-00 y8 intake manis have 4 small holes above each runner/portit needs to be sealed up i used jb welb just have to make sure it is smooth on the side that bolts to the head

I will find you a pic of what i mean hold on

 

I'm in the process of doing the same thing...the EXACT same thing. I, as well, had the same problem. Didn't really pinpoint what the exact problem was, I just killed as many birds with one stone as I could...here goes. The first time I put it on, I used a 2000 mani gasket, z6 IACV, and the y8 tb gasket with the ls tb. When I got sick of the idle...I tried it again. Picked up a 96 mani gasket, used the y8 IACV, and got the ls tb gasket, and adjusted the idle screw...put it all on at once...problem solved. Hope this kind of helps ya man...you've been askin alot about this swap, tryin to get it right .

BTW...you did jb weld the air induction ports, right?

 

I have removed and installed more then 50 y8 mani swaps and never had a problem except the holes and it would idle high as ****

I have a y8 mani with ls tb on my 91 hatch with a d15b in it

but i used the complete mani so i wouldent no about the iacv

But If not that get a real tb gasket and try that

Hmm, more than likely, but what tb/gasket is your friend using?

 

y8 gasket w/ gasket maker for the im and just "gasket maker" for the the tb. Im guessing it works fine because i hear no hissing or any leaks. Would it matter? Before i used the z6 tb gasket along with the ls tb and it leaked like a bitch...but now im guessing i fixed that problem with just gasket maker.

edit : my friend is using a y8 gasket...with his z6 tb gasket w/ a z6 tb. so about almost the same but different tbs.

 

tttttt

 

has anybody ever used a z6 IACV with their y8 intake manifold that actually worked?

even if my IM gasket or my TB gasket were leaking should it cost a bouncy idle like this?

 

ANYBODY? i have been searching for hours and i cannot find ONE single **** about a y8 mani on a z6 install! WHAT THE HELL!

 

Double post owns me...

 

Maybe my manifold thread will help ya out a bit...check it out.

 

&lt;--- Using z6 IACV on y8 manifold

OK im a bit closer to my goal...for some reason...HOW THE HELL are you using a z6 IACV on a y8 and its working! Well anywho took apart my IACV again...cleaned it and reinstalled it...but this time.....it idled fine for about 30 secs...on the ftiv untill it switched over to my z6 IACV and then it started to bounce...so the IACV has to be the problem! I can smell it!

1. the z6 does not mount onto the y8 without grinding the big metal bump.

1. i dont know even though if it looks the same it isnt working for me!

 

ben...the y8 iacv runs 2 coolant lines too right? one to the ftiv and the other to one of the ***** on the block...is that correct?

 

At one point, I thought my IACV was fugged up (2000 Y8). So, I personally went and pulled an IACV from a '95 EX. It wasnt the culprit, but it works fine now ... the z6 IACV is on there.

wtf did you just plug and play? didnt you have to shave off that bump for your z6 iacv to fit? how did you do it?
