ATP Wastegate Swingvalve?

[DetroitTurbo]

Is this the correct wastegate swingvalve for my T2 turbo?

Swingvalve For Internal Wastegate 5 Bolt to 4 Bolt Discharge : atpturbo.com

[tryingbe]

nope. 3-4 bolts won't line up correctly.

[DetroitTurbo]

I think I found it.

How would I get a v-band to work with the turbo-back kit from TU? cut the DP and weld in a v-band adapter?

[The Pope]

you have to make a DP

The OBX may be a good thing to try

[detobias]

lol Pope beat me to the reply

you could start with a TD DP,

but you'll need to add some flex since you won;t be using the OE style ball/socket

plus adding the mandrel "P" (or tight 90) piping to redirect the ATP outlet away from the P/S pump back down the tunnel..

may as well scratch build it, rather than adapting a TU DP

look kinda like this LOL

[DetroitTurbo]

Sweet, I found it. $69 isnt too bad for that. What does suck is the cost of v-band clamps!

OBX 3" V-Band Downpipe Low Profile 90 Degree Steel NEW

So If i was to get that and the TU turbo back exhaust, I would have to weld a 3" v-band onto the pipe where it will meet? couldnt I just have my exhaust shop weld the DP to the rest of the exhaust?

yeah you'd need to add the band clamp piece, you can buy the clamps with both pieces together on Ebay though. I would consider FWDs JRB type exhaust, may be cheaper without the 3" donut?

The radius on the OBX d'pipe sucks though. It should look like this:



No use putting on the nice ATP Swingvalve if you're just going to throw it into a brick wall just like a stock SV by having a crappy radius off the ATP piece.

[DetroitTurbo]

Well I ran into some problems so I'm not going to be doing the swing-valve till next year, but when I do I will make sure the radius of my DP is similar to what you posted.

Do you have another pic showing how your 90 degree pipe curves down into the rest of your downpipe? How close is the downpipe to the PS pump (I'm assuming you wrapped the pump/hoses and or the downpipe to sheild the PS pump from the heat?

What PS pump are you using (I was reading on another forum that there's two types of PS pumps for the TD's. One is the more common metal reservoir ham cam style and the other is a ZF plastic reservoir style which leaves more clearance room for a conversion like this).

[GhostDaytona]

damn that looks good, i wouldnt mind that on my engine,,does it flow pretty good?

[GLHNSLHT2]

No I don't have another pic. This pic is not of my car, it was posted in a thread I started over on TM.com asking about the ATP swingvalve. As you can see they're using the ZF pump. You'll never get that bend with the metal pump.

As for flow, it flows awesome. Rockslinger put one on his minivan as per my suggestion, and with the wastegate flapper flapping in the breeze he hits overboost by like 4500rpms. So it's definately moving a lot more air than it was. His minimum boost is 15-16psi.

[The Pope]

as we go into winter. There is a few build threads that will be popping up. Shadow is talking about a stage 3, which is of course exciting. But Rocksliger / Luke plans a build thread for the ATP with photos. This is a GREAT swing valve. But being new not a lot out there for it. With Lukes thread and others as it moves forward this SV is going be posted all over in the next few years. But getting going is always a little slow lol. So be bugging rocksligner relentlessly to get something up, light a fire under his A to get him moving lol.

[DetroitTurbo]

I love build threads, too bad I jacked up my trans changing the pump and now I have to pull it. Might get a performance rebuild on it if the money is right. The motor is done, and as far as new parts go I really just need exhaust. I'm not looking to go over 350whp ever, so I might go with the ATP with the smaller radius.

[GLHNSLHT2]

if you're going to use the smaller radius you might as just as well keep the stock style swingvalve. The whole point of the ATP piece is for flow. So you want the big radius as well or you're just back at a stock piece.
