unless you did an engine swap, or april fools joke, your chevy has a 5.3L
thats not a real funny april fools joke, changing all the ford/f150/250 to all chevy tearms. i dont think when someone is asking for help, and all their words get changed.
There isn't just someone sitting around out there waiting to hand you over all the exact spec's you need to twin turbo your engine. There is alot of research and factoring that needs to be done. How much boost do you want to run? This will ultimately determine the size of the turbos that you need. Why do you need twins in the first place? If you want high-teens and above for boost numbers your heads will try to separate from your block, so O-Ringing is a good idea as are ARP head studs. You will need your PCM reprogrammed to recognize boost, as well as a MAF with the range for boost. Wideband O2 sensors aid in tuning greatly. You'll need a higher volume fuel pump and larger injectors to supply all that incoming air with a sufficient volume of fuel. Ultimately, it's what you want. There is no book on 'how to twin turbo my F150' as every application is different. I suggest you start by reading Hugh MacInnes' book 'Turbochargers' one or more times, and really take it all in. Then YOU decide how big of turbos you need. You will need an intercooler to keep your EGT's down below 1500, and an oil pump capable of keeping the turbos lubricated. It isn't as simple as you want it to be.
Most people don't realize that turbocharging a new EFI engine, particularly an OBDII engine, is MUCH more involved than simply bolting up some turbos and plumbing the intake/exhaust.
