First post so be gentle on me please. A little background on where I am coming from. I have just aquired an XG drag ute and want to run a Turbo 6 engine in it. Power will not be huge to start with as it will be run as an 11 sec combo at around 450 RWHP but engineered to step up a little down the track. I am also trying to get my head around the best starting place for a healthy Turbo 6 combo. I have read that the EGas engines (both BA and BF) had uprated Rods and Springs. Is this correct? Is the cylinder head as good a starting place as a T head? Alternatively, would it be a reasonable move to grab a Late 06 BF N/A engine and throw some rods, pistons and valve springs etc at it to bring it up to Turbo specs? As you can see, I am more interested in the core engines ability to hold up under the stress of Turboing. Are the above mods heading me in a Turbo spec direction? I would want to run BF electronics etc and am unsure about VCT issues on both the EGas and BF N/A engines. All the outboard stuff like manifolds and Turbo are not an issue for my project. They can be soughted and sourced when I have a total plan. From what I can see there are plenty of way tougher engines within this forum so the help will be greatly appreciated. Thought it would be smart to go to the source for these questions. Really interested in your input.
