Got bored and started taking apart my turbo. Is there anything special I should know before going any further than the pics indicate? And I have a question about "clocking" the turbo to face the right way, which part do I need to loosen and turn, the bolts circled in red, or the ones in blue? And can I get another downpipe flange (do I need to)? This one only has two bolts, and it seems most I have seen have three or four. Also what about this wastegate, can I remove it? Or should I leave it?
