Re: need some information

you need more than just the intake and exhaust manifolds, like complete engine harness, ecm etc..

Re: need some information

Stuff needed to convert is covered in depth in the Conversions forum, but....

A stock 4.3 + turbo = kaboom, unless you're planning on running low boost, and what's the point of that? Stock 4.3's are too high compression to run our 15psi on. Change the pistons (and rods as long as you're in there). Heads are the same, crank is the same, block is the same. Other stuff you'll need, just to get you started.....

Upper intake
Lower intake
Throttle body
PCV system
Fuel rail with injectors and SyTy-specific fuel lines, or braided line to plumb.
ECM
MAP sensor
Engine side wiring harness
Interior wiring harness
SyTy specific instrument cluster pigtail
Lots of wiring diagrams to sort out the wiring nightmare you'll get into
Exhaust manifolds
Crossover pipe
Downpipe, converter and custom exhaust system
Turbo with wastegate
Turbo oil feed and return lines
Turbo coolant feed and return lines
SyTy specific oil pan, or butcher your stock one for oil return fitting
SyTy specific power steering pump
SyTy specific turbo air intake system

There are more, but this will give you a shopping list to start with.....
