Second the cam timing.
Also, don't spend 750 bux on a chip, you won't gain even 10hp from it. Just use a factory mass-air setup if you are worried about it...or leave it speed density.
Your math makes me laugh. If you truly want to know how much lag "x" amount of tubing will add to a system, you have to use the cubic feet per minute flow rate of the engine compared to the cubic feet of IC tubing , not "12 inches adds 100rpm" equation listed above.
What volume of air is a 2.3...
He's full of crap about no rewiring and all of that, otherwise, if you do a little searching around, browse my site (which has detailed turbo swap pages), and such, you can figure out exactly what is required.
Takeoff's include the tires...they are wheels/tires taken off brand new Mustangs when dealerships upgrade them to aftermarket wheels before selling, or for the customer right after they are sold.
Everything in the fuel system would be fine. You'll just need to be able to command the ECU to feed the engine roughly 30% more fuel to compensate for the lower stoichiometric ratio required for ethanol. The "cheap" way to do this is to throw in ~30% larger injectors. It would be far from...
Isuzu NPR intercooler is the only other non-aftermarket IC that fits well and has tubing available for Mustangs. Otherwise, there are FMIC kits available specifically for 2.3T Mustangs. Clicking on the link in my sig would point you to an FMIC kit for the SVO.
Quad shocks don't improve handling, they were only designed to minimize wheel hop during acceleration from a stop.
To eliminate the rubbing tires, you can first try rolling the fender lips. If that doesn't work, the offset of the wheels is just wrong and there is no way around it, aside from...
