Question: Pedestal on a stock turbo?

[LWATSON]

If your going to weld cast get some nickle electrodes. Preheat both parts to be welded and peen each weld with a center punch putting a row of punch marks down the middle of the weld. Then weld the next pass if needed. This relieves the some of the stress the weld creates when it cools.

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?

That's correct. I am debating on cutting off the bottom of my stock VVT housing, adding a flange to it and then making my own pedestal. The extra exhaust housing is only to test the welds. That exhaust housing is not even close to the same size as my poor little stocker. haha
But I'll definitely be cleaning the hell out of the cast piece, beveling and preheating before I start any welding. I plan to use very short beads that overlap and probably two passes, peening the beads the whole way.:thumb:

I wish you alot of luck the VVT turbo is different then the IHI turbo that was in that link that was cut and done up. With the VVT like on your truck know you will not have as much area to work with to weld to get the heat into before it starts to crack.

I'm wishing myself a lot of luck too! Like I said if it doesn't work out on that other housing I won't even bother messing mine up. Hopefully the perheating and peening will eliminate or at least minimize the cracking.
If it works it could open some new doors to upgrading the intake system on our trucks. Fingers crossed fellas!

The VVT housing has less housing area to work with then the IHI. So you will have a very small area to work with around the exhaust port to get them to match up thats were I think you will have the most trouble.

I was just looking at Trent's site, and he has the BD pedistal for sale, too.

Just trying to give options....
