What I did this weekend.

I'm missing 2-1.5" 90s to finish the job.

 

[crushers]

you look like you are having fun...
is that the 3B or for the 3B II?
cheers

 

[lowenbrau]

Its for my 3B but it might end up on Charla's 3B.

 

[crushers]

i though Charlas was a 3B II?
i will have to stop by and take a closer look...
cheers

Looks very nice, but I'm not sure its BEEFY enough???

 

[Radd Cruisers]

Nice......

Is the flange heavey enough to prevent warping when welding?

One guy made a plate 1 inch thick to bolt up his flange prior to welding to keep it from deforming.

Guessing your are stick welding it also?

Why not just take it to a machine shop and have them check and mill it if necessary?

Naw, Charla's was one of the first BJ73s off the line. Oct 84

3BII started in Oct 88?

Its not a lot heavier than the factory 13BT one that's kicking around here. I likley would have gone with 3/8s but the 1/2 was sitting in the metal bin. I bolted it to an old head when I welded it and that limited the movement. The big thing is vibration, its a heavy turbo that's hanging off the side of a four cylender ciesel. Its gonna shake a lot.

would it be for an old chrysler turbo? Start doing a few and you have a business. I am sure many of us would pick them up. Head to the wreckers get a bunch of turbos, rebuild them, provide the fittins and hoses. Ya it might be a good side thing.

for about $50 you can get the fisihed pieced planed flat at the local machine shop.
cheers

Well, I'm inspired. I was just gonna flip my manifold but that looks like something I can maybe handle. What have you got into it for material costs? Did you mig weld that? Can you give us a breakdown of what you used and where you where you got it? Sorry for the heap of questions but like I said, I'm inspired!

I have about 12 hours into it

2 - 1.5" weld 90s (about $5 each)
2 - 1.5" weld Ts
1 - 2" weld 90
4" x16"? (didn't measure) x 1/2" hot rolled... would be better if it was 3/8" cold rolled
4"x4" x1/2" cold rolled for the turbo flange
A few scraps of 1/4" to fill the funnel to the turbo flange

It is designed for the Garret T-03 that comes on the Chrysler products but we have a source for brand new turbos (same spec) at a good price so I'm undecided if I'll spend a day at the wrecker pulling one or just pay the extra $400 for a new one.


Yes I used the little mig. (Miller 135) Figured to go back and reweld with the big mig (Miller CP-200)but it wasn't necessary.

Marc Ritchie is talking about having the plates water jet cut. This will save a bunch of time and we could sell everything as a kit. Let's wait and see if it all fit under the hood.

It takes a bit of time to port match everything, but I'm surprised how little. I'm sure I could do it again in about 8 hours.

 

[Radd Cruisers]

Well done, I think most guys have had good luck with a bigger mig if you preheat the material a bit before welding.


Thats a smoking good deal for a new turbo, why pull a junkyard dog at that price.

i can safely say i wasn't impressed with the water jet. too many times they messed up and when it was finally done it still wasn't fantastic, acceptable but not fantastic...
and not cheap either...
cheers

How about that electronic machine shop from one of the lists a couple years ago?

Might be worth a shot. I remember trying the CAD interface, it wasn't too bad.
