sounds like you have access to a shop and alot of knowlage. perhaps another potential to gain some ground on this subject. i say buy the car and jump in with both feet. maybe start off with just a small boost and work from there.
Sorry, but I've seen what happens to these threads. I've decided that when I'm done with mine and have solid numbers from a dyno or some good strip times I will share what I have done to my NA. BTW a small boost will only get you to stock SRT power.
I will however clear up some issues I have read on the forum.
No map sensor on the NA. I know for a fact mine has both maf and map. Its in the service manual and I've seen it on the motor. Part #a0041533228
FMU's won't work to tune boosted applications because there is no return line to the tank to install it. Sure there is a return line between the regulator and the tank. The fuel pump and regulator are mounted outside of our gas tanks so the fmu would have to be mounted there and not in the engine bay where it is traditionally found. Cheap way to tune for boost? Ask Paxton and other companies that use it. $85
As far as the internal parts the sc and na share. I have found that they share the same block, heads, pistons, and same size crank. The crank in the NA might not be forged but I don't think we would have such a high redline if it weren't. Afterall its usually over revving that breaks rods,crank etc...The difference in compression comes solely from the shorter con rods the SRT uses. That being said the majority of critical parts related to power handling are identical.
I'm sure there is more misinformation that I have read here and maybe I'll post it later.
