So I've been doing a lot of research lately on turbocharging the LFX. Ive been working with and modding the platform for a couple years with simple bolt ons and tuning, but as most of us know, this engine is a powderkeg for potential but no one really has ventured into the specifics like LS engines or Hondas vtechs where there's tons of research n development n trial n error. What has me stomped is GM producing yet another block with newer provisions for oil and cooling ports. Along with strenghtend rods (titanium) and forge pistons which should be interchangeable. I'm not sure if the lfx using titanium rods or not but I know they're stronger than the LLT 3.6. Also the bolt pattern to the heads on the lfx and lf3 are the same so I'm thinking I can just put those on this block kinda like old sbc's use to swap heads. Which would bring the compression down a bit. LFX static compression is already high and swapping heads should help lower that ultimately a bit longer engine life.
Another thing to note is the LF3 intake manifold, its patented to the lf3-4 I believe and to me is a hell of an invention because the intercoolers and throttle body is all integrated into that one piece and its truly a great design as the runners for the cold side and hot side are short therfore the pressurized air gets to the engine quicker. I've checked the exhaust manifold (collector manifold style, all integrated into one exhaust port) on both the lfx and lf3 and not only is the visual inspection the same but the part number is also the same so the lf3-4 turbos should bolt right up to the lfx manifold. All we'd have to figure out is the cold and hot side routing unless the heads are indeed interchangeable and we can use their patented air, intercooler throttle box and the piping is basically done for us which only leaves the exhaust side. Twins seems like the easier route as redoing the manifold to collect into one. What do you guys think? I have another engine in my storage unit I could mock this up to nust to see it come to life. Any advice or help would be nice.
