"We" are looking at building a local (US) effort 24 valve twin turbo Milano and to that end, we're looking for any and all suggestions related to the project (as planned...) I don't really want to get into the turbo versus S/C pros and cons, or cost versus simplicity, versus bang-for-the-buck arguments; 24 valve TT is what is on the table.

We would specifically like to hear suggestions on suppliers for custom-sized intercoolers, sourcing sectioned plumbing, or perhaps a local (Seattle-based) fabricator of turbo-installs who can make custom plumbing in-car. Also, information on turbo-types (roller-bearing turbos etc), inlet and exhaust sizing differences between the T-3 and T4 for example, opinions on the products available from Turbonetics (pricey), versus some of the Chinese-made turbos out there would be good...

Naturally, I have a strong relationship with Dawie at Glenwood in South Africa, so much of our primary direction will be drawn from him, but I want to hear what else is out there! Also, even something very basic and specific - like Turbo-Charging 101 - pop-offs/blow-offs/waste-gates - built-in or external canisters, electronic versus mechanical boost-control etc etc would be much appreciated.

For starters the goal is to build the project based on a standard 24 valve 164 motor to validate the direction. After some confidence in the concept, we will have a 9.5:1 compression 3.45 litre built with dished forged alminium-alloy pistons and forged steel chrome molly rods (just like some of the other big-bores that we have done with Dawie...)

For now though it will be the standard 10.0:1 domed piston motor from a stock 164 LS running a maximum of .5 to .6 BAR boost through a single 80mm throttle-body! Intake runners will be the standard 44mm GTA types with custom dual plenums.
