Can cracked 14b hot side housing be salvaged?

[_Madman_]

I recently brought a 14b, but turns out the hot-side housing near waste-gate flapper is cracked enough that you can see light through the cracks.

I want to get the car to drivable condition as soon as possible, and I'm not sure what to do.

Can I use the cracked housing, weld it? I can also get a hot-side from Chinese 16G, but I was told that it creeps like crazy as the waste-gate hole is very small and the opening for the wheel is huge.

What are the negative consequences if I put on a cracked 14b? I still have a T25 on car, but I have a buyer for it, and he doesn't want to wait.

Can hot-side housing be ordered online? Are they expensive?

I might have an access to 16G housings as well, internals are wrecked, but housings are ok.

Nope, it's trash. I wouldn't trust welding pre-turbine cast to just any welder, and the cost of getting it properly welded would likely outweigh the price of a crack-free replacement housing.

The negative effect would be extreme lag from a non-sealing wastegate system.

Would you recommend mixing and matching the turbine with 16G Chinese housing?

The Chinese housings are hit and miss in my experiences. Over the course of 3 setups, only one lasted more than 10-12000 miles. The other two first stripped several bolt threads. After I repaired these with helicoils, each one warped and would not hold a good seal to the manifold. They are clearly made from inferior metal. It's a noticeable difference when using a grinder to port them vs a oem. The bit cuts threw them so easy . If I could get a used or new oem one for a good price I would. Otherwise it's a gamble.

Not really.

You know all those worn brake rotors and other cast that we send to the scrapyard.....

I've been going with the Kinugawa brand parts myself. They are made in Taiwan, not China. They aren't the cheapest off-brand but they are of good quality and consistent from my experience anyway. Also, they come with a 34mm wastegate flapper that is ported out bigger than the China housings I've seen.
