Aluminum Intake Manifolds?

A friend of mine bought a foundry (!) and is considering producing a genuine cast aluminum intake manifold for us. What's the wishlist?
I'd like to see larger intake ports - that actually match the head. I'd like a front facing intake for better turbo packaging, but there's only a few of us that could use that. What other features are needed? Maybe a two piece design so we could bolt up different plenums?

I would think that there would have to be pretty good bang for your buck here. the turbo market would be pretty small imo

^^ That that would be nice

Yes please. Just modify it so you can remove the fuel rail without removing it, and improve flow as best you can.

Just the aluminum is good enough for me though since it's stronger and can be powdercoated or polished to improve the look of the engine bay 100 times over. That's my main complaint with our engines is that big plastic piece of crap.

I doubt it will cost that much, I would guess about half that.

Most people will not switch just for the sake of switching, but I can see an aluminum manifold being popular for

1) boosted folk that are concerned about the plastic manifold
2) people that want a showy engine bay and want something they can polish, paint, or powdercoat

I'm trying to convince him to do a front-facing version for the I6 to simply my boost piping.

I5 should be first. We're bigger lol

This is the only thing I was wondering... if two versions would need to be produced for each motor but it seems like the 3.5/3.7 manifolds are interchangeable which is good because it means less cost for the manufacturer and so less cost for us!

On this note though: I would be interested in one that simply flows better than stock but would prefer the stock intake/TB location because I don't plan on doing a whole lot with the truck and having to fab an intake for it would kind of suck....

unless you guys came up with an intake to go with a top/front mount style manifold :naughty:

Yeah, Jeremy had PM'd me about my extra one so I sent it to them a few weeks ago. That reminds me, I should email them and see how the progress is going.

When I did my motor swap I compaired both manifolds and didn't see a difference so I used my 3.5 cause it still had the TB on it. Once they finish the first prototype they are going to send it to me for a test fit and make sure everything works fine. I'll post pictures and info once they do. :thumbup:
