does anybody know if this is the right flange https://store4.yimg.com/I/cheapturbo_1745_204150 for this turbo http://www.digitalpose.com/mbr/1/148...1800132_vl.jpg? it looks the same but i want to make sure.

yessir, that is the correct flange

Re: making a down pipe (DubyaAye)
 

mig or tig is fine...16 to 18 gauge is adequate

Down pipes are pretty forgiving.. if its stainless I would tig it.

I like to tack the bends together with a MIG while mocking the downpipe up on the engine. Once everything fits to my liking I have it TIG welded. The TIG yeilds nice looking, strong welds, and smaller profile welds.

quick question...
dubyaAye has the 5 bolt turbo and 5 bolt flange...
the turbo i purchased has a hole on the turbo...next to the compressor wheel...
probably for the internal wastegate....

can i just make my downpipe with the flange just covering the hole... ?

or

do i need to put a piece of metal to weld it closed

thanks

Just cover it.

yep just cover it up and weld away. 3 in is a tight fit on there. you get pretty close to the edges, but you should be cool. i just migged mine up last week and for the hour my car ran, it worked great https://honda-tech.com/forums/images/smilies/emwink.gif
good luck
later
