Td04 hdi

With a hybrid you are milling the exducer outlet/housing, what about the rest of the exhaust housing? It's all designed to create a low boost threshold (aka low flow and high restriction) on a 90bhp engine, but we're pumping out anythimg up to 170 on a stage 2. Personally I think there are better solutions than trying to bodge a different exhaust turbine into a housing its not designed for and then turning the boost up, all of which is going to exacerbate issues with back pressure. Ease of installation is no benefit at all when the time spent rebuilding the turbo is fairly similar to what it'd take to adapt a better suited one... But that's all just my opinion.

Donkeybubles, iirc that is a k03s so should be pretty ideal if you're stopping this side of 200bhp.

What do you think turbo manufacturers do that area is not a restriction for us.
Any hybrids on the forum, like mine jp etc have all made good, reliable power with no lifter or emp issues

Have you ever measured emp or monitored whether you're having valve spring issues, or monitored exhaust gas temperatures or are you just living in ignorant bliss... Sounds to me like you haven't by your lack of knowledge...
