I ended up ordering both the intake and exhaust wraps yesterday, and it's supposed to show up today. Since my HLA's won't be here until Monday, there's a decent chance I'll be attempting to put them on today and tomorrow. I'll post some pictures and let you know how it goes. Looking at the intake manifold, it's probably going to be a huge pain to wrap. There are a ton of inlets and outlets for hoses, injectors, etc. We'll see what happens. I don't want to deal with stripping the paint off of it or sand blasting it, so I definitely would love to wrap it instead. Once I've got the car running, I'll take some temperature readings and we can compare them to an unwrapped manifold to see if it actually makes any difference.

Man, Amazon has been really screwing with me. They cancelled my order of stainless steel zip ties, and now the intake wrap won't be here until tomorrow. The exhaust wrap should still be showing up sometime today, though. Looking at the little exhaust manifold, I have a feeling it'll be a real challenge to wrap. There isn't really runners. It's just sort of a blob of cast iron. I'll try to make it work...no promises that it'll be pretty, though. I still need to track down a turbo blanket, too.

Alrighty, the wrap has just arrived. While I have the turbo manifold stuff all laid out on my bench to wrap it, I figured now is as good a time as any to port out the wastegate. I don't have my measurements with me, but if I recall correctly, the flapper itself is about 10mm wider than the wastegate bore. About how much larger do I want to make it? I know I don't want to get too close to the size of the flapper, just incase I go too far, but a number to aim for would be nice. I'll try and take some pictures and make a nice step-by-step guide for anyone who decides to do this in the future. Unless there is a guide floating around on these forums that I've failed to find in my searches.
