OK I am putting a t4 setup on my car and I just got in the v-band flanges and they fit loose in the exaust out does anyone what I am suposed to do. Thank you.

 

better discription needed.

 

OK i set the flange on the hot side of my turbo and it just falls in does not sit on the lip around the exaust fan and does not fit in the slot around that lip. thank you

 

i don't understand your question. the v-band flange is supposed to be welded on. are you talking about the clamp?

 

no I am not talking about the clamp I got a new t4 turbo and it didnt have a flange on it so I bought some new ones. So I am supposed to weld it to the turbo?

 

Welding a regular V-flange will not work. You need the actual piece that companies make to weld in there. It fills up all the gaps. Don't know where you can get one though

 

OK the hot side of the turbo is cast is the piece I need cast because I heard that you can only weld cast to cast and the flanges I have are s.s.

 

u gotta weld it on ...

 

can I weld stainless steel to cast iron cause if it can be done I will take this to a welding shop I dont think my wirefeed can do this but if anyone knows if i can weld ss to cast without anything special please let me know

 

yes, you can weld stainless to cast iron. Use nickel filler

 

You have several options:
- have a place that welds v-band flanges to turbing housings weld one to your housing (I'm not sure that your average welding shop is equipped to do this or not)
- buy a turbine housing with a v-band flange already welded to it
- don't use a v-band

-Max

 

rgr, I use a Nickel 55 rod. Works fine IMHO, havn't had one crack yet!

 

If I dont use a v-band what can I use. I thought that that was all I could use with it. Somebody tell me another way of doing this please.

 

If you have one of those turbos with a plain non flanged housing then you will have to take one of the options that Max already gave, or use a housing with a bolt on style flange.Basically if you can't get it welded on you will have to swap out your turbine housing but i don't see a problem with welding it if the correct filler rod is used.

 

thank you

 

Ok instead of starting another thread I will juat add to this one. I was wondering if I could just get a small piece of pipe and weld it to the turbo and weld one of the flanges to the other end of that.

 

just switch the housing, way easier and you know its right....look to spend about $80 to $90, but you can specify your exhaust housing size....i would just use a common downpipe flange on it so you dont have to worry about making a downpipe with a v-band
