So here's the idea. I want to cut the bottom part where the up pipes attach to the exhaust side of the turbo, and add a flange so I can use an aftermarket pedestal. The goal is to raise the turbo to gain clearance for bigger runners or a custom intake manifold. Might be a little crazy but that's what this site is about right? Thanks for the help guys.
Question: Pedestal on a stock turbo?

Well ultimately I want to get a bigger vvt and twin off it later. But I figure since i don't have the funds to support major mods like a completely new turbo I will just contine to make small improvements where I can. Bring able to do my own metal work allows for stuff like making a pedestal, up pipes, headers, a fuel tank and an intake manifold though.:thumb:
I am planning on using a tri y style concept on the intake manifold. All run to a 3" collector in front. Then for some tri y headers and 2" up pipes. If that turbo doesn't breathe amazingly well after all that I'm screwed anyhow haha. But either way it would be good preparation for a bigger vvt later.
Why not just make a riser to raise the turbo, then just make longer up pipes. OR just remote mount the turbo where the twin would usually go. Flip the manifolds around the run the exhaust forward and in front of the motor. I think that would be less piping then remote mounting it and running the up pipes up and over the motor.
you can try calling rick dlance, he may have some laying around. Otherwise call a machine shop and give them the dimensions. What about the base? if you are cutting the bottom off you would just mount it off the t3 or t4 flange. I would think t4 or even t6 based on the size of the bottom of the turbo once you cut it off.
I would not go cutting the factory pedistal your not goi g to gain from it. The ar on the exhaust housing is what hurts the vvt turbos. Also once you cut the cast housing I do not see you getting it to weld back to a stainless pedistal and holding up. So that means your going to have to find a cast housing to try add and match the ports up and weld it to.
Personally, I would avoid welding anything cast at all costs. Especially in this kind of application. You would have to be a verry good welder and/or be verry lucky to have it hold and last for any length of time without cracking at the weld joints. If I were you, I would just save my money and time and purchase a turbo and pedestal combination that will allow for what you want. Much more likely to hold up.
A guy over at the Place made one. It seemed to be holding up ok so far.

I'm not really looking to get any more out of the turbo by doing this. Just get it out of the way until I can actually afford a better turbo. In which case i will have already made a pedestal. If it doesn't work out, perhaps Santa will bring me a new turbo without telling my wife.
:rofl:Thanks for the info Tom. Definitely good reading. I just remembered that I have that junk turbo I got for free and the exhaust housing is trash. I'll give it a shot on that thing this weekend with some 1/2" steel plate and see how it holds up to some tests on the welds. It will be interesting to see how it turns out.
The links Tom posted the guy made a pedistal out of the bottom part of his lb7 turbo. Alot to do to save a few hundred bucks. I reread your first post I take it you wanting to buy a aftermarket pedistal then cut the bottom half off your stock vvt turbo. Since you have a extra exhaust housing see if the scroll ports will line up with the new pedistal even or if your going to have to make a spacer to fix that. To weld a flange to you vvt housing your going to want it clean as hell and want it pre heated to get the weld into it. Might be able to machine it and tap it and use a gasket and not have to weld it. What pedistal are you looking at buying to work with this?
