WOAH!!!
ive never seen the back side of a G60 intake..
those things are the ***!
im gonna get me one of those. my runners enter the plenum from the back, so this one will be less prone to interference.
i edit all my suggestions, dont go with the digi manifold, use the G60 one.
shorter runners for sure, looks like they could be a bit larger too.
anyway, the G60 mani looks like a way nicer piece than my digi manifold.
congrats on someone using one.

funny, the guys in the G60 forum on the vortex talk about using a early CIS manifold to get better flow.

aww hell.. I was hoping this thread would ANSWER my questions instead of adding more confusion...
someone send me a G60 intake mani and i'll dyno test all three... you can even have the mani back afterward, I just want to know!
i'm thinking they're all about the same if everyone is saying the grass is always greener with the other manifold, but it'd be nice to get some data on it.
Seriously though, anybody want to pitch in (money/manifold) and help me put an end to the madness!?!? Manifold remains your property, cash used for dyno costs/shipping.
I've got a completely stock 1.6L NA and i'm willing to do the labor. I'll have it dyno tested with all three manifolds and post the findings.

well, I don't know which is best.
I really don't think the stock manifold is choking an N/A that much, I would really prefer it on a non turbo because of the long runners, really helps with the low speed power.
as far as forced induction the gas ones are such a clear upgrade over the diesel one I don't think it would really make much of a difference which gas manifold you get, it is going to be light years better.
I think the reason the G60 guys like the early cis one better is that the angle it enters the head is closer to the angle of the runners in the head than the G60 one, but how much difference that makes, who knows.
dyno testing would be the way to go.

Just an idea. But you could use a TB adapter from a 16v to any 8v manifold instead. :roll:
P/N is 027 133 070.

would probably work good for N/A or low boost applications, but the oval makes for uneven clamping force around the adapter, prone to leaking.
(according to a buddy with a turbo CIS gasser)

Well if the one above won't work, how about this one.
This can be bought from BBM.

since I have an 83 GTI that I drive daily and the guy I bought it off of knows everything about the CIS deal. The intakes were really similar, but the TBs are different from what I gathered from him. The later styles just had one flap and no secondary, the intake was a little different. He had always said that the newer style was better for performance in the gassers, but the older would yeild a little better milage. For a diesel probably won't matter just plasma cut a piece of steel and a peice of pipe and you should be good :wink:

Just leave the intake off!! Period end of story, no worries about restrictions! :lol:

What's your turn-around time?
I have a g60 manifold and throttle body which I gutted and welded up to make an adapter but it's only 2" ID, so I think I'll pick up one of those BBM adapters.
I also thought one of the concerns with the n/a diesel manifold was flow differential and specifically poor flow to the middle cylinders? This of course is all heresay as I've never seen any real numbers.

well, I won't get my head studs until tue/wed and i'm leaving thu/fri for cali until the 10th.
What I'd really
like to do is run each mani through a full tank of fuel as well as dyno-run-marathon them (all three mani's in one day, one after another) at the end after i've "DD'd" each mani through a tank. That's probably longer than you want to be seperated from your manifold but I think it'd give us all sure-fire information.
EDIT:
plus I don't have the funds right this moment for a full day of dyno runs but i'm open to donations
