ATP 3" Downpipe = Huge Failure

[GetBoosted84]

Hi everyone,

Just wanted to post up my torment in dealing with an ATP 3" downpipe that I bought for my GT2860RS setup. I bought the downpipe from a user on this board who in turn bought it from another user on the board and that guy bought it from yet ANOTHER person on this board.

The downpipe has gone from:
boosteda4md > pac1085 > BONFIRE074 > GetBoosted84

Anyway, I purchased this downpipe for my GT28 setup and the downpipe was supposed to fit a GT2871R setup so it should mount up correctly right? Wrong, the downpipe will not mount up no matter what I do.

I ended up having to take my car to JM fabrication to get them to make up a piece to fit it on to my neuspeed exhaust (which mounts in the factory location, blah blah blah). After Jim gets it up on the lift, we find out that one of the bolts from the downpipe is (and has been) hitting my axle and causing it to go right through my CV boot and score my axle.

He tried to move it as much as possible but it still looks like it's hitting the axle and so I'm not really sure what to do about it.

What do you guys think?

Here are some pics of the mounting issues (click for larger copies):

the 2871r and 2860rs have the same exhaust housings right? I have the 3" V-band ATP DP too... I hope I don't have the same issues. Have you tried to dis-connect it from the hanger near the tranny, getting the DP and turbo setup and then trying to get it back on the hanger?

ATP advertise their "turbo" kit with the 2860rs and their manifold/DP combo.. if the exhaust housings are the same I'd try e-mailing them to see what they say.

p.s. that sucks.. I hate wasting time.. but espically money.

Either you have the down pipe in the wrong position since it looks to be sitting too high and toward the transmission or you your turbo position isn't correct for that down pipe.

[Poopie]

my best guess is that the downpipe was for a t3 style turbine housing

[mike-2ptzero]

Which 5 bolt/vband plate do you have on the back of that turbo and are you running internal or external wg setup?

Because there are 2 different 5 bolt plates that ATP has on thier site.



and



One puts the Vband lower then the other one.



Poopie - From the ATP web site.

Custom ATP stainless steel 3" downpipe designed to work with Longitudinally mounted 1.8T cars such as Audi A4 and VW Passat. Made to work with ATP cast iron manifold and any of the following turbine housings: GT28RS 5 bolt, GT 4 Bolt 3" opening, GT/T3T4 - 4 Bolt 2.5" opening, T3/T4 External wastegate 5 Bolt, T3/T4 Internal Wastegate 3 bolt, . 3" diameter stainless steelAND the appropriate V-band adapter to the particular turbo (V-band clamp included). has provisions for the factory oxygen sensors.

the DP has the bellmouth v-band adapter (top pic)

Just a standard 3" vband like they put on their dp's. Both of the 5 bolt adapters also use 3" vband.

His dp looks a bit longer on the top bend vs what they show on their site.

I'm pretty sure when I took that photo, the very front hanger was disconnected. I contacted ATP today and the lady that answered said that the only difference in their downpipes is the adapter for the turbo at the v-band. I think she is wrong though so I am going to try back tomorrow and see if I can get a tech on the phone.

Either you have the down pipe in the wrong position since it looks to be sitting too high and toward the transmission or you your turbo position isn't correct for that down pipe.

I can't see how it would be in the wrong position because if I slid it to the right it would hit the transmission housing and to the left it hit the firewall.

I think you're right.

...are you running internal or external wg setup?

External wastegate (synapse 40mm) setup.

This really sucks. I trimmed the bolt on the downpipe again tonight. There is nothing left to trim now so I'm hoping that it will not keep hitting my axle and I can replace the CV boot. I put white out on the axle where the bolt was hitting to see if it still hits it. If that doesn't solve it I think I am going to have to scrap the whole damn downpipe and start from scratch which is going to burn a huge hole in my pocket.

[audiness]

how many ATP threads do we have to have before someone from ATP mans up and fixes the apparent quality issues.

I for sure will never buy anything from them. (unless you like cracks in your manifold, i guess)

[Poopie]

i haven't heard of any manifold cracks. those are the only decent thing they make and fit.

[GetBoosted84]

Yeah, the high flow stock replacement is the one that was giving everyone headaches. I'm putting a brace from the turbo to the block though just to be safe.

[A4ringedONE8T]

If your running an external WG you should have this adaptor on the turbo



You have the other? And Mike is correct, each of those 5bolt - Vband adaptors place the Vband in a different spot. The T25/T3 should not matter as long as you are using the correct Vband flange and NOT a Vband exhaust housing.

With my 3071R setup, I had a T3 3071R, 5 bolt with the vband adaptor shown ^ and the ATP downpipe and it fit perfectly. The only fitment issues they warned of was a vband exhaust housing as it positions the turbo differently. When I did my 3076R setup, I verified fitment of the DP with it and they were indeed correct

If you have the adaptor plate shown on the turbo on the left, it should bolt up to the downpipe. T25/T3, 28/30 series shouldnt matter

[GetBoosted84]

That could be the issue then since the GT2860RS was modified to support an external wastegate instead of the internal one that is normally used. Basically the flapper was welded shut and the external wastegate was removed.

[Poopie]

i have that flange with out the vaband sitting at my house. we can throw that on and see if the hole lines up with with down pipe. then all you need to do is get the v-band section welded on. or buy the new vband adapter.

[GetBoosted84]

Oh cool. I'll give you a call tomorrow so we can figure something out. Not sure on scheduling but I'm gonna try for tomorrow since you are not going to be around tonight.

Did it ever work out for you ? I have the same setup but straight vband no 5 bolt

Holy necrobump. Yeah got it fixed years back. Ended up having to cut & re-weld it IIRC. Too long ago to remember for sure. But we did get it together. That was several turbo setups ago at this point.
