I was wondering if there would be any interest in a sheet metal intake manifold that would match the 2G head?
To my knowledge, nobody currently makes one. I talked to Marco and he said that he use to build them on one-off orders but no longer has the time to do them individually. He did however say that if I pooled together 5-6 people that would buy one he could build them for about $600 a piece.
These would be great for the Auto-x guys and should work well on drag cars that want to retain the 2G head because of the higher port velocities that are seen with the 2G head. The biggest restriction internal on a 2G is the intake manifold, so this would be a good place to pick up some power.
Let me know what you think and if you would be interested in a group buy on these.
Thanks
Michael

Marco (the man that I was talking to about this earlier) is the owner of Magnus Motorsport...that manifold is for a 1G but the one I am wanting will work on a 2G.
That is what the manifold would probably look like though...
I don't know, I will check them out. I think the Venom manifolds were more targeted at drag racers though and might be ?too large? for auto-x...
Thanks

Well, I think that it will come down to your turbo choice more than anything. Get an AutoX friendly turbo and you will be just fine .
Of course, "AutoX friendy" turbo will not require a sheet metal intake (which mostly helps on the top end), so you are back to where you started . Ask youself this question: "Are you getting a sheet metal intake because you are running out of things to change, or because it can really improve your car?"
I guess my point is that stock manifold is probably your best bet if AutoX is your main objective.
Sorry, I wasn't all that clear, but I didn't necasserally mean a 2G stock intake . Installing 1G manifold on a 2G head is not easy, but it is not much tougher than installing a sheetmetal intake.
But a 2G stock intake is not as bad as most people make it out to be... I have seen some really fast 2G's with stock head/intake/TB. Even, you are not doing all too shabby with it .
I would just prefer to install a sheet metal manifold in the first place and not end up replacing a 1G stock in the future to upgrade to a sheet metal.
Here is something else interesting about my set up...I am at 4500' in elevation...[]
Ah...you see, IMO, the 2G head is a better head...
But I am sure there are many that can spout off numbers of how the 1G is faster and blah blah blah...but I really don't want to hear it.
I may be going to SEMA this year and the track in Vegas will be open. It is 2500' but that equates to about 10% more air...
Utah is jacked when it comes to air quality. The local dyno is always correcting for about 9000' because our air is absolute junk. It is extremely dry and thin. People regularly go to Denver and run 2 - 3 tenths faster then they do here, even though Denver is 1000' higher.
Why can't you use the Magnus 1G manifold on a 2g? Aren't the flanges for the head the same? Why don't you just port match the head to the intake manifold.
I am using the 2G head for a reason, intake port velocity. If I take a head designed from the factory to be used in conjunction with a manifold designed to create a high velocity air flow pattern and then stick a massive tube 2" from the opening, I am pretty sure it will mess up flow pretty badly.
Anyway, I am looking for a real solution, not a hack job. But thanks for the suggestion.
Guys, I think that you misread my post... I said you can "convert your head for a 1G intake". As in taking a 2G head and port it out to a larger 1G port size.
I did not say anything about 1G head being better. I know the reasons why some people believe that 2G heads are better. I do not buy into that theory, but that is getting off topic .
Well you probably don't buy into the theory because you want to slap a 1G intake on a 2G head...
The point I was making is they are not even remotely compatible when you consider what they are designed for. The 1G intake has a fairly large runner volume and is pretty long. A small port head will have difficulty building any kind of port velocity with this set up.
Now take a smaller, tapered runner and put it on a 2G head and you are talking port velocity. Tune the length to about 6000 RPMs and you have a very broad power range. It may not make the peak numbers of the 1G head/intake but it will have more area under the curve, which is what actually moves the car.
