It's fairly labor intensive.. but the parts shouln't cost that much.
Never Ever buy a FMU to fuel one of these engines. I'm not going to rant on about that but a FMU should never be used to fuel a engine PERIOD. I'd put a piggy back system on before I'd use one of those steaming piles. Ok.. rant finished.
You'll need:
Sy/Ty stock exhaust Manifolds
Stock Sy/Ty style turbo/downpipe
Marine Intake Manifold (e-bay) 400.00 ish.
30lb/hr injectors or larger.
HPTuners. I have a file setup for 10psi
Some 2.5" mandrel bends (steel)
E-bay Intercooler
Moroso 2-part epoxy to affix a bonnet to the Throttle body. Or have a flange welded on ... A guy on another site said that a LS1 throttle body is the same size but has a nice long snout on it that you could attatch a bonnet to with out welding! You'd need to transfer the shaft from the 4.3L to keep the same throttle apendages.
Cut/weld pipes so it's arranged in a flowing fashon.. like mine or not..up to you.
You'll need to plum the oil feed off the drivers side oil pressure feed line (above oil filter housing) You'll need 5feet of -4 AN hose and fittings.
There's a fitting you can put where your oil level sensor is for the oil return.
(Guy's with 3.8L F-bodys do it with no problems) I've not tried it yet. I put mine in the hard way... took off pan.. ect.
Coolant feed to-turbo/from turbo.
Relocate MAF Pre-turbo.
Put IAT sensor into incoming pipe (after turbo/IC)
Tuning.... Tuning... That's what is going to make or break these setups.
If it's not tuned right or skimp on fueling it correctly/timing/settings you'll be looking at a yard orniment with a blown engine. 4.3L don't take detonation well. It wipes the mains right out of them.
3.8L buicks are more forgiving and just blow head gaskets. We've got too much clamping force on our 4.3L head to blow them out.
I've got a entire set of pictures I can send you if you contact my e-mail.
Hope that helps,
