Yeah I just couldn't bring myself to weld on that shiny new housing. Now its tired and dirty, and I don't feel as bad. If I decided to ship my turbo back sans turbine housing I'm going to get my spare block on the engine stand for now I think and work on a brace. I got some 347 round stock, and just need to figure out material for the brace. I know @bbundy had to use chromoly because steel would crack on him.

Steel would fail?
It probably depends how light-weight your trying to make it. a 1/8" piece of round stock wouldn't do much.
The OEM formed plate for the 1jz turbo brace is around 1/8" thick but its formed from one piece at about an inch wide and I expect its somewhat optimized for the loading. it is essentially a section of 1" channel @ 1/8" thick with the way its formed.
I would probably do 0.5" round with a 1"x 5/32" tube for the block/turbo mounting ends. no need for heim's imho.

I like bobs better. Its a "spring board" kind of mount, that supports the turbo from underneath. Just takes the weight off. I don't want to ridgid mount it.

Lol. Pics above are rebuilt turbo pics. Painted and shiny.
Current plan is to take a friends old 99 motor and toss it in stock. Run low boost until I get time/money to rebuild the real motor.

Someone correct me if I'm wrong.
Things needed to swap a stock BP4W in place of my VVT motor.
Cam sensor extension harness.
New oil feed line to wrap around the block to the oil pressure port
New drain line and bung
Anything else different between the 2 motors?

Don't the VVT motor mount plates fit on the 99 oil pan anyways? Just without the extra bolt?
I may just run my VVT oil pan on the 99 motor anyways, the 99 oil pan is already off. Might toss bearings in as well (we have a spare set).
