Im getting ready to start my turbo build. im looking to build on somewhat of a budget but not a tight one. i want good power but also reliability. im not shooting for crazy high horsepower number, more so just looking to build it and see where it ends up and move forward from there. im looking for the turbo system to be adjustable as far as boost control, not just preset boost levels. im not building a race car just a nasty street car. Im starting with a 3.0l sc motor.currently installed are 9.3:1 euro p's and c's 964 cams and raceware rod bolts.
im planning on going to a 930 crank and 97-100mm 8-8.5:1 p's and c's. im thinking of going twin turbo, 3.2 intake converted to efi with haltech engine management, twin plug with coil on plug. the fabrication stuff i can do no problem. where my knowledge lacks is on the efi side of things.
my questions are:
is there anything i need to be aware of as far as wrist pin height for the 930 crank?
is there anything else i will encounter with a 930 crank in sc cases?
any other engine management that is as big of bang for the buck than haltech?
as far as sensors and such what are the best options?
what size turbos should i go with?
opinions on different waste gates and blow off valves?
any issues with the heat from rear mounted turbos and the oil tank?

I apologize if i sound like a newbie, Ive been building cars and bikes for years im just new to the porsche world.

feel free to chime in with and opinions and advice
thanks!
