UIM spacers

not sure what these things are called again but was wondering where i could get a set...i think a guy had some awhile ago....i need a set of the spacer things that go inbetween the LIM and UIM because im doing direct port nitrous. so any help in the right direction would be awesome.... also was wondering with these spacers i assume u need gaskets on both sides of the spacer when installing? would i be right in that?

You mean the Phenolic Spacer's? If so I believe it's the guy on here that go's by the screen name phenolic. For your purpose tho i'd be worried about a nitrous back fire through the intake blowing something like that apart. I'd get something machined from aluminum as I believe the phenolic spacer's are some sort of fibre/resin but I'm not completly sure.

yes you are right i am doing turbo and direct port nitrous but i have a polished manifold and would like to not drill into it and also was told they put more space from the downpipe and the intake pipe, which helps cuz everything will be cramped as shit in there...lol...

I thought that the spacers would be made out of aluminum and definitly want a set that are....so does anyone know where i can get a set of those or would like to do a set for me? also how much do u think a set like that would cost?

Yes, I am the person that was/am trying for the group buy for the 2.8/3.1 engines on the spacers.
I can guarantee it'll handle boost and high temp since these spacers were more targeted towards boosted applications to begin with.

I would have to bump the interest list to see who is all available still on the GB. I'm sure though, if you really wanted them, it can be arranged, but it will not be as cheap than if we got a handful of people involved too.

Click the link in my sig to find out more info and who to contact that is making them.

Guarentee as in like if i blow one out of there it will be replaced for free?

Also, how thick would you think you'd need it? Keep in mind that you might need to tap your own holes for your nozzles.

im not sure how thick i need them...enough to take the pressure and also have the holes for the nozzles drilled and tapped in...i think the size that needs to be drilled is 1/16 NPT body threads whatever that means...lol so suggestions on the thickness would be cool. Also my heads and manifolds have been ported and polished...does that mean that these have to be cut to match the porting or how does that work?

I would probably go with 5/8 or 3/4. The spacers should be matched to your gaskets.
So if your gaskets are cut for a bigger opening, then the spacers should be too. I would request the batch of spacers to be already ported out a little bit, wouldn't be a bad idea. I mean, if you're modding your engine, then you should have had the ports opened up to accept some ported spacers too.
