The 335 and M3 are two different tax brackets.
Where a 335 owner may spend $6500 on mods a M3 owner may have to spend $11,000 on somewhat equal performance increasing mods but like I said two different tax brackets. I've heard that VF engineering is planning a twin turbo kit for the E92 M3, (you can call them to confirm) at a price inline with M3 performance upgrades, (once again "tax Bracket").
So then the question becomes:
Modded vs. Modded ?
So what would happen when you pulled up to the light this time ?
Hehe. Only time will tell.
But in this case comparing modded vs Stock is fair because your talking about a 20k or so difference in MSRP.
Plus you get easy gains and much better "tuneability" with a turbo engine as opposed to NA. So I'd say close to triple the price for the same gains on a turbo engine when compared to an NA engine
