Ive seen plenty of v8 single turbo setups with the mani routed like that... Theres even a few on here. wantafastz28 has a huge single setup on a v8. Im just saying whoever drew the diagram drew the plumbing backwards on the exaust side. And have alittle more than a foam box when you want to make a project thread

 

I'm selling a cheap brand new T4 on ebay right now...http://cgi.ebay.com/ebaymotors/ws/eB...MESE%3AIT&rd=1 $200 bucks no reserve. It may be big enough for your setup, good luck with it!

 

Would love to but with no information, I can't tell what it'll do for me. Sorry.
