Aluminum upper intake manifold
Did mkaake(I believe he was the person investigating this) ever come out with procedure for the aluminum UIM swap? I remember this being talked about, but as yet I haven't seen anything on it.

So if that'* all there is to it, why doesn't each of us have one already? It has to be many times stronger than the plastic one. Is it a cost issue?

But to put the composite intake in to perspective, they are used in the LS1 and LS6 engines, so they aren't that bad.

Mine has given me more than 5 years, and so far it look to have no degradation or warp...
I will say alluminum is a great conductor of heat, I'll bet the Composite keeps the incomming air a shade cooler than does the alluminum...
But at the same time, chances are really good the the alluminum unit will not fail..

-and as I've said so many times before, if you remove the direct contact of the EGR stove pipe to the composite unit, it would no doubt never fail.
-remember, it is the heat from that stupid EGR tube that wrecks the composite over time-

Thanks for all the responses guys. Hopefully you're right Macho and I won't have to deal with replacing the thing again. Well actually I take that back... I hope this car lasts so many miles that I have to go through two more UIMs. If I ever have to replace it again, is it an easy thing to modify the EGR stovepipe? You don't have to answer in-depth; I won't be dealing with this issue for a while, hopefully. Unless it'* worth it to get in there and do some modifications right now, that is.

The L26 upper intake manifold is available from GMPartsdirect.com for $106 to your door. I forget who it is that sells the TB adapter, but they do the N* throttle bodies for the SII L67'*.
Anyone know if the L26 UIM is portable. Would be nice if it could be ported another 8-10mm and the TB and adapter with it. And with a stroker kit.
