Stock V.S ATP turbo exhaust manifold

[935racer]

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.
