Well, ok. I have an S4 GXL. Yea... a fatty... but it is going to go on a diet. Removing A/C, air pump has already been removed, Aluminum hood. Small diet, but still a diet.

I have RB header, dynomax catback, and RB presilencer. Custom air intake box w/ cone filter (+.0000001 HP!). Also, I swapped the S5 manifold in, and it is electronically actuated using.....

6-ports are also actuated electronically using summit racing RPM switch and a lumbar pump.

TB mod, no HP gain... but thought I would mention it.

I am not a big fan of being able to do 180+ MPH. Or even 140+ MPH. I am a big fan of 0-100 acceleration. Or just acceleration in general.

I am planning on putting the 4.3 rear in and maybe a torsen LSD? Not sure about the LSD, how does it affect daily driving?

Next summer I will also be planning to get a very aggressive street port, but not bridge. Not that daring yet.

So, I was wondering, does the 4.3 make a big difference in acceleration? Like, how many seconds off the 0-60 time? Would it better to go bigger? I saw another thread with someone going 5+. Though, I want the 4.3 for the better gas mileage over the 5+.

Would all this lead to pretty good acceleration? Any suggestions? Standalone is in the future, but not until after the port.

I can't afford some things, like lighter rotors etc, but someday I will be able to.

Thanks!

P.S. Staying N/A for the reliability and uniqueness. Not many "quick" N/A's. I know I won't be smoking most things with boost, but it would be nice to be able to keep up or out accelerate a new GT mustang.
