Without a super or turbocharger, how much hp could I pull out of a BMW Z4?

Question

I was going to add a head and cam kit, full exhaust, a boost chip, and an intake (any other cheaper upgrades would be good too). I'm looking at the Z4 3.0si from 2006 and I'm just curious what I could do with it. I'm looking at a few new cars and if I could somehow cut the 0-60 on this car down to 5.0 seconds it would be amazing. Thanks in advance for your input.

Answer 1

80HP.

If you get everything that comes with a turbo kit except for the turbo, you would get at least 35HP. The kit includes Intercooler, Intake, performance chip, piping, blow off valve, and some other parts.

exhaust, head and cam kit would also add around 40HP.

The BMW Z4 M coupe has the 330HP BMW M3 engine with no turbo or supercharger, and that does the 0-60mph in 4.9 seconds. So you would need 330HP to get it down to 5 seconds.
