Very brave for tacking together that whole thing without welding as you go. I suspect you'll have to add material or change a thing or 2 due to the shrinking of material in each joint throwing it off.

Doesn't matter. Metals including stainless steel shrink when they are welded on. This becomes more problematic when there are a lot of weld joints like what's there. No matter what you do, it's going to move a little. That doesn't necessarily mean you are going to have to add material, but it might change the flange locations a bit, or change the way the tubes meet up with the flanges.

^^^ Not neccesarily true. I understand your point, though. Really depends on robustness of the jigging and whether the welder skips around alot or not... He might also be tacking the whole thing together in order to dis-assemble it and make his jigs from the tacked-up pieces. Then go back and start welding, making whatever adjustments might be needed. I've been working in Indycar, ALMS, and Nascar as a fabricator for over a dozen years and don't see anything wrong with how he's doing it. COT cages are not as thick, but they are completely welded in fixtures without a problem. Total shrinkage over a 5' rollcage section of chassis is less than 1/16". Obviously 4130, not 304...

the only spot that moved was where the up pipe connects. that part wasn't in a jig and it BARELY moved.. A little adjustment and she is all good

When you mock up the up pipe, do you do create jig that simulates the firewall too?
Or do you just sort of assume that you have sufficient clearance if you tuck the turbo close up against the block?

I'm thinking of trying to make my own off of JDM twinscroll header, but the thought of pulling the motor and putting it back several time for fitment is not appealing.
