i have a ihi mazda turb, what is the best way to weld or braze an exhaust pipe to the cast iron outlet on my turbo?

Go to the welding supply place. they will recomend a wire/stick for you. Don't braze it.

i heard (somewhere) that the IHI o2 was cast steel...
in that case... weld away

most turbine housings are cast steel

i'm just going to avoid this one..



wouldn't touch it with a ten foot pole, unless you paid me to, in which case, it's your money and you'll spend it how you want.

Welding to cast can be done.Using the right rod it will hold.I've done one on a friends car and it holds.He's had it running for about 3 months and no leaks or cracks whatsoever.I even beat it with a 5 pound hammer after I welded it.Like 4sillypwr said go to a welding supply shop and tell them what your welding and the'll get you the stuff you need.Hope this helps.
