Anyone care to comment? I have read a few posts from people who have run them. I saw that malone ran one on his franken with good results. Anyone else? Does anyone have flow numbers that show improvement? Are the runner I.D's bigger than the stock 1.6td's I.D?

how much is the ATP manifold? 935racer has a sweet tubular pulsed manifold. equal length = equal EGT's across all four cylinders, and faster spool up. i'd say worth the money!
-
yes, indeed that would be sweetness. I remember Dave quoating around $900 for the tubular. I found a nearly new ATP 8V I can pick up for about 150.00. They are supposed to flow more than stock, and be a drop in fit, no fire wall contact. They retail for about 275.00

ATP appears to have a good rep. Comments?
-
It might be hard to fit a 3" DP because the turbo sits lower which mean the first radius will be much closer to the o2o shift linkage, not positive on it though I haven't done it to date.
-
The ATP manifold isn't exactly a drop in unless you have a turbo with a Ford/Saab style T3 flange.
-
I stand corrected, Drop in for a non vw t3 turbo.
Do these flow more than stock?
Dave did you do the setup on malones car?
-
In all honesty it doesn't look that much better than the one fitted on our TD engines. I'd save the $$$ for something else.

yeah i agree, i think the only advantage is that you then have the option to run other turbos, but you'd need all new plumbing and stuff, so unless your upgrading your turbo or using a gas intake manifold there isn't much of a point of using it.
-
WE used a ATP manifold that had a t25 flange welded on, same kind of thing, it will flow better than the stock unit no doubt, no a hell of a lot better but better.
Mike what do you mean by saab/ford style flange? Different than a standard T3 flange? It sure looks normal from the picture.
-
This type of cast manifold, there are several of them for sale on ebay and not too expensive.

I have seen that one before. I asked how long they would warranty the manifold. 30 days only. Not very long.
I just thought the ATP manifold would be a good upgrade. If the down pipe does not fit, and the turbo oil lines need to be changed, it may not be worth it. It was just a thought.
I have a 1.6TD exhaust manifold on the way to Passenger to get fitted up to a 1.9 head that is going to be ported. Just thought the ATP might give a bit extra flow.

I am going to be putting on the Merc 300TD Garrett T-3. I am also getting one of Daves modified intake manifolds. The merc turbo will not fit on our vw manifold unless a adapter is used. I think it will bolt onto the ATP. If I cant use the 3" DP though , I might as well stay with the vw manifold and just go with an adapter.

iirc, only vw came with the trapezoidal pattern, while saab/merc used the pictured rectangle shape
-
the chance that the pp down pipe is going to work with this manifold is extremely slim. its pretty much not going to work with out modifications.
-
subsonic if your going to run that merc turbo i would just go ahead and use the ATP manifold. I think it looks much better than the factory one more so if you have to make an adapter. Dave may be able to tell you if his DP would work. I wouldn't think it would be that different. And maybe you could send it to him and have him modify it for you.
Just my .02

I'll be building Jim a custom downpipe for the MB turbo regardless of wether he uses the atp manifold or the stock manifold with an adapterplate. The only thing is that the atp manifold places the turbo lower and further back than stock, it might make it more difficult to clear the o2o shift linkage... I'm sure some searching around on the vortex might yield some answers though.
And yes the VW t3 is the only t3 turbine inlet to use that trapezoid style flange, virtually all other t3 turbos use the standard rectangular flange. The reason I asked if there was a difference though was because some turbos have the same port sizing and slightly different bolt spacing like a certain vnt20 turbo I have in the shop... same port size, different bolt spacing than all the other vnt20's I've seen.

From the seller of the ATP manifold
"I see... yes, I myself had a similar problem, not with the ATP mani though. I originally ran a Steve Langford kit (cheap, and the mani was a straight out type similar to the ATP - apposed to upswept slightly. What car are you running it in? From the instructions that came from my Langford kit, it told me to bend the selector arm that pivots from the steering rack (on my Rabbit) on a vertical axis - the arm of that selector points toward the front of the car and swivels lefts and right as you go through the gears. I bent mine in the vice. It was about 20 degrees upswept and I bent it to be horizontal when in the car i.e. at 90* to the vertical part. I'm just about to find the picture that'll save me these thousand words! Follow this link http://autotech.com/instructions/i715098K-099K.pdf and I'm referring to the flat metal top part of the relay shaft. Fro the diagram I found on the mk2/3 is that the relay shaft is on two pieces so is easier to bend. Basically just bend that flat. It should clear the turbo then - unless....you're running something bigger than a T3? The instructions from Langford that I have are for all 020 trannied Golfs A1,A2, A3.
I can't find my picture, it must be on my laptop.
The ATP has the added benefit that it can be reversed, i.e. the outlet flange can be between no's 2 & 3 cylinder or 3 & 4 which would be closer to the linkage. My Langford on was straight out the middle so no choices. The linkage works fine after bending btw!"
Does this make sense to you guy's? I have not held those parts in my hands, so I am not visualizing it well. :?
I am going to get the ATP. It's a good deal, If it does not work out with the Merc turbo setup, I will just end up selling it for what I paid for it.
If it flows more than the oem unit as stock, I am gussing it will do even better after it is matched up to the head with the big port job.
Has anyone gasket matched up the turbo to the exhaust manifold?
-
Done! I just bought it.
Dave, it will be on the way to your shop in the next day or so. Lets hope it works. Keep'n my fingers crossed.
