Yeah, but I only paid $160 for my HF mig. For the extra $100 I spent I would rather have something that looks good in my garage <G>...

So, what do you guys think of this basic design? Simple, effective, and somewhere between a log and full 4-1 design. The runners for cyl 2/3 will go straight out. Cutting the center elbows and welding them like the picture will help direct/smooth exhaust flow, and keep the pulses from 1/2 and 3/4 seperate. The turbo flange sticks out about 5.5", and should leave room enough for a 2.5"dp. I may end up rotating the center portion about ~30* up to help clear the 'shelf' area, but preliminary measurments says it should be ok as is.

Really I think space will be the biggest thing to deal with

Yeah given the shelf and the hood clearance i dunno if you are going to be able to come in close enough to fit the turbo dude.

yeah, that's why i'm thinking about angling the center collector portion up. As is, there is about 1" between the turbine/exhaust side and the shelf. Plenty of hood clearance.

If you can get the turbo in there it is a great design. All the gases flow the right way. Clearing the shelf will be the biggest hurdle. If you use a small compressor housing with a large wheel that would probably do the trick, but you would have to have the compressor housing machined to pull it off... it would be rather stealthy though since it would appear to be a much smaller turbo than it really is.
