wasn't sure whether to put this in here or in the FI forum...I have a T3 .63 A/R PTE turbo sitting here and the only option for 3" was a 4 bolt, so i opted for the 2.5" v-band instead, i was wondering if anybody has, or if it is even possible, to throw the hotside on a mill, shave down the existing v-band, tapper/port the hole to 3", then weld in a stainless 3" v-band?

 

what about a taper down pipe from 2.5-3" right where it exits out the hotside?

 

i'm actually wondering if this will work, vice using a 2.5"-3" transition like most use

 

why didnt you buy the 3" 4 bolt and machine that? a 4 bolt 3" flange is pretty close to what you need.

people weld vbands onto turbo housings all of the time.

 

Sure its possible, probably gonna be cost prohibitive though. Setting that up on a mill would probably cost more than just buying another housing

 

If you have a 3 jaw chuck on the mill it would take 10 seconds to setup

Best would be to just throw it on a lathe if you have one, then you could taper it too. If you want to get fancy you can make your new vband press into the housing and then weld it.

 

ya i think it would be a little to unbalanced to throw on a lathe

but should of went with the 4bolt and welded on a flange

 

sorry just trying to get my 5 posts

 

you must have a **** lathe.

just use an angle grinder and grind it dow. to weld a vband on if you wanna do it cheap.

 

How do you think they made it in the first place? We have 50+lb turbine housings that are spun on the lathe.

I've got a big *** clausing that wouldn't give a rats *** about a turbo housing, a big box store lathe would not be fun to be around though
