turbo help
Here is the thing, my friend recently gave me his stock turbo off of his 91 talon for free but the thing is the housing where the exhaust enters the turbo has a hair line crack but its only on the inside and hasnt reached the outside yet and I was wondering if I can still reuse the turbo by just welding the crack and grinding down the weld.Here is a picture of where the crack is.The white line is where the crack is.(this is not my turbo, camera needs new batteries)

They all have cracks in them. I haven't see a mitsu turbo that has more than 30K that wasn't cracked. If the crack doesn't go thru to the wastegate, you'll be fine. If it does go thru to the wastegate, you can do what o'malley said and get another turbine housing. The 14b comes with a 6cm turbine housing. There are a number of dsm vendors that sell turbine housings. I'd suggest going upto a 7cm for some improved topend flow. The 14b are potent lil turbo's. Infact, thats what most 2G guys upgrade to.

and generaly you can't weld the cast iron, it will just crack where you weld it. If it dosn't go through, then just use it. Most older stock turbo's have cracks in them, don't lose sleep over it.

Heat it up first. A good welder will be able to do it trouble free.
