Also with that PCV hole, if you are boosted, and you drill the hole and run a vac line out of it and in the back of your manifold, its a VERY good idea to put a check valve on it for sure. You dont want to be pressurizing your crankcase while you are boosting.

I have alwasy wondered something, what if you run a line from there to the intake side of a turbo (before it goes into the turbo) and also run the larger crank case tube to that area. I wonder if that would be good on the turbo.

Anybody have any pictures yet of it installed??

I know that you can install the 2.3 Mani to the 2.4 Head without the flange. But how much more harder is it to install the mani to the head without the flange? Will I have trouble with the ground bolt I have an auto. And with the flange I will have to get two 2.3 manifold gaskets? One for the manifold side of the flange and the other for the head side of the flange? And the head side of the gasket will have to be modded to fit the head right? That means pretty much cut out the holes for the top bolts and slot out the bottom for the bottom bolts?

i need a flange, does anyone have one for sale.

i had an auto and i used the flange had no problem with the ground bolt at all...i havea 96
now if you bolt up the manifold without the flange the ports are a bit off and the mani gets pretty heat soaked

i need a flange big time, and anything else for the swap. ummm, i need the throttle adapter plate. would i need different throttle cables(being maybe too short).
Check the gp forum I am running a GP as soon as I get an okay from the mods, I will also be offering a stud kit as well to make things easier.

DOES THIS ADEPTER SEALS INTO THE LD9 HEAD OR PLUS I NEED SOME SEAL OR RE-USE THE OEM SEAL?

you need a gasket on both sides of it.

This gasket is custom made?
How many performance i can get by installing a LO mani with this adapter?
You can get eleventybillion performances.
is there a way to get a hold of the guy that has the adapter for the HO/LO 2.3 intake manifold to the 2.4 i wanna convert to the HO manifold and also woundering about the pcv valve being blocked and what bracket and sensor that i gotta use to the swap and if anyone wants they can email me at chrisb_18360@yahoo.com or just leave it here thanks

Damnit you made me choke on a cracker...
But I LOL'ed
totally not neccessary to use that material for that adapter accually to be honest that entire flange in my opinion is a waste you still have to slot the whole to bolt it on so whats the difference if the manifol bolts to the head or to that flange but if people just got out a dremel they can make the B shaped runners on the 2.3 maifold in less then an hour and be done i did mine 7 years ago and took about an hour to modify 4 runns to match the 2.4 head and notch the holes
basicly your buying a manifold spacer.
how small that flange is you wont see any performance or gain out of that flange. ZZP just strated making ther SC intercoolers that go between the intake manifold and the SC out of that but your talking a chunk 2" to3" thick and about 14x10. something that size will absorb heat and give off a heat soaked effect that flange on a 2.4 wont. piece of steel or aluminum will work just fine and easier to find

you guys realize this thread is nearly 5 years old
so it is someone brought it back from the dead, oh well adapter flanges still aren't worth it all modifications on the flange can be don to the manifold

im glad you dont have a 2.4! cuz you'll lose horse power the way your talking about doing it.
Mines ran the way his was. Never had a problem he use to have a nice 2.4. If you port match the intake for the b-ports. You will be fine. Cept you will have to add jb-weld or weld it at the bottom of each port. Then match it to the 2.4 as the 2.3 port on the bottom is lower than the 2.4 head. That or match the 2.4 head to it. It's only a little bit that needs to be done.
But of course what do you know a newb on here talking smack to a older member. Along with acting like he know what he's talking about.
Priceless.....

look here you @!#$ talking @!#$. me being new to this forum doesn't mean @!#$ about what i know or what i do. use that smack talk on someone else.
o and do what you want how you want, i'll do the same!
Nice

Little frisky are we?

I'll talk what ever i want to. Don't come on here bashing some one for saying something that works and has to work if you even want to put the 2.3 mani on the 2.4. Well since the spacers in this thread are long gone. Which means you have to do it that way unless someone is making them agian.
Either way i guess it is stupid to gasket match then port a head also.

You want to guess what your doing when you do it the way he said? Gasket matching

Let alone guess what? Do you even have one of the spacers? Probably not or you would have known it doesn't line up the greatest. Along with it will affect flow just like running a tb spacer. Mainly because it adds volume to the runners and well the whole intake. Which might be worse than the heat soak from running it the other way. No body has ever tested it that i know of. So
