Re: problems with install on rpm turbo
its the stage one bolt on kit.....the adapter plate is on correctly, it sits on the manifold perfectly but the downpipe is way off....i didnt unbolt the bolt on the downpipe by the starter.....the stocker came off without me having to remove it

Re: problems with install on rpm turbo

Re: problems with install on rpm turbo
When I installed my DP for my stage 3 it was a hair (half inch) off, so I fabbed a small adapter bracket to secure the DP, which wasn't big deal.
FYI
It is important to secure the DP because it will eventually come loose and create false knock, like mine did.
Also replace the stock studs and use lock-tight....

Re: problems with install on rpm turbo
if the downpipe is rusted to the cat or has been welded you will need to cut the pipe, twist it and re-weld it. The adaptor plates have not changed and have remained the same for a few years now. I think we ran 100 initially on the cnc, and still have about 20 flanges left.
9 out of 10 people have a trouble free installs. Out of the 15 plus i have personally installed i have had 2 which did not bolt directly up and it was due to either the downpipe being welded to the cat, or rusted to the point where you could not re-position/twist the downpipe to line up with the new bolt locations.

Re: problems with install on rpm turbo
My truck's dp/cat/turbo/manifolds were 100% stock and just like you said the turbo bolted up to the manifold like butter.. but was way off as you can see from the pics on the dp flange. Those pics were taken even after we cut the dp support bracket bolted to the firewall and rotated the dp some. I ran out of money, the shop ran out of time so we cut the dp behind the o2 bung and rotated it the extra degrees needed to be done with it.

Re: problems with install on rpm turbo
if the downpipe is loose in the cat inlet you should be able to twist the downpipe to line up with the bolts. your's was probably rusted together thats why you cut up near the 02 bung. Other then that like i have said, nothing has changed in 2 years and there are more people who have had trouble free installs then ones like yours.

Re: problems with install on rpm turbo
Another thing to consider....
The heat of the downpipe can contribute to significant warping. I've had stock downpipes "sproing" off the turbo when pushed off the studs.
I would expect that there may be some wrangling of the DP necessary in something like this. If it bolted up clean, great, but it shouldn't be out of expectation that the bolt on the DP ear would have to be loosened, and the joint at the cat as well.

No problems with the install on my RPM stage 1,loosen the clamp at the cat,soak with spray penetrant and rotate into position,I cut the bracket off mine but it was bent and not being used.Use loc-tite at the turbo bolts.That was about it.

Re: problems with install on rpm turbo
You guys are very lucky. I bought my truck clean and around 40,000 miles had to seperate the stock downpipe from the cat, it was absolutely impossible. Took about 5 minutes on a lift with an oxy acetalyne torch to make it glow red hot before it would come loose..
