Preheat, and also when your done you need to let it cool down slow.

 

thanks alot guys

I would also make an adapter unless space is at a premium!

good call haha. That'd definitely be a waste of time and money to weld a v-band to a 4 bolt flange. The purpose of this isn't to save space or be able to use v-band....it's to never have to worry about those gay 4/5 bolt flanges having bolts to back out. That's the most frustrating thing EVER.


To let it cool: What I did when I did mine, get a big <U>medal</U> bucket as well as a second smaller bucket, some playground sand at Home Depot, and lastly some aluminum foil.

First just put the turbo and bucket with all the sand in the oven.....separately. The sand take alot longer to heat up evenly so keep that in mind (start the sand first).

Once the sand is heated up througholy, take the turbo's hot side out and weld it up. This doesn't take long so leave the sand in the oven. Once the turbo is done being welded quickly take the sand out of the oven and dump like 1/2 to 3/4 of it in that second bucket you have. Put the turbo with the centersection going up and down (so sand can be there). Now take that second bucket and pour the sand back in to encase the turbo. Wrap the aluminum foil around the top to seal it in and let it sit for hours. When I did it, my sand was cool after like 6 hours.

Some may think this is overkill and say to just weld it, however stainless to cast iron isn't a normal type weld and there is no sense in cutting corners and risking having to do it all over again.

EDIT: Oh and if you're transporting it anywhere make sure you have a couple towels and several mit-style oven mits. That bucket is going to be hot as hell for a long time haha.

^ That's a smart idea to let it cool really slowly.

 

thats not a bad sounding idea,
and yea i was thinking about welding on to the 4 bolt flange but the v-band covers the holes

Don't. Just eliminate the 4 bolts and your life will be alot less stress-free. Another way you can do it to give yourself some more room...is take the ATP 4-bolt to v-band adapter and then weld that to the turbo. That is what I did, but I took of the numbs for the bolts......

 

Id just send the housing to ATP and have them machine it for a direct v-band setup:
