You can solve this even cheaper: go buy a Holset variable geometry turbo like the HE341VE. Sure it's a 40lb turbo, and will need to be a custom top-mount setup, but who cares when it will make 55 pounds of positive manifold pressure amirite?
Variable geometry turbos are popular on diesels because they have much lower EGTs than gas motors, so the variable stuff can actually survive a reaonable amount of time.

That makes a lot of sense. Also, I read that another trick that porsche uses to reduce lag is to briefly lean the mixture as the engine starts into boost. Any tuners able to pull this off with MS? Or, is it too risky?
Neg Cats for (me) restating crap.
But folks have tried VNT turbos for decades in the motorcycle and car world. It never works. the exhaust gas temps are too high in a gas engine. Don't bother. Buy a modern turbo and forget this forever please!

Thanks for setting me straight. I've been spending way too much time at the dealer getting my car fixed... nothing to do but read up on the hot new models. Apparently, this is more "marketing" than a "performance upgrade". Just what Porsche needs is more reliability problems...
This is my audi's turbo and downpipe after 1-2 minute of first gear "drifting" in the snow recently. Doesn't take much to get things hot in a turbo car.. Rip k03s
