Z4M power upgrade
Hi guys,
I have Z4M and I want to upgrade it's power to 400bhp(+). How can I achieve it without turbo or supercharger? So far, I removed the catalytic converter and I'm lookin for some directions from your personal experience. (BTW, removing the catalytic converter has side effects?) Thanks. |

Maybe if you do : Full catless exhaust, Cams, CSL airbox, Pulleys and Tune you can get close to 400 crank.. but at that point its gonna cost as much as a supercharger that will give you 525-570...

The Flux Capacitor is about twice the price of the ESS S/C.
Not sure if it would be worth the extra cost. Might be easier to pass smog test though.

If you do choose the Gen 1 + plutonium approach then an advanced dashcam with nightvision and radar as well as a kevlar vest are highly recommended accessories. In either case a lot of road is necessary to attain the required speed to build boost pressure. |

Hahahaha it's a secret so to speak, I'll give you a hint (Fueling fueling fueling). Basically I'm willing to claim that my car will run faster than any FBO Z4M that is on the rear 3.62 diff.

Sure thing buddy... just share it or don't even mention it at all. And if it's nitrous then not really a secret, most people are not willing to do it.

I would go with a tune, exhaust and rear diff first. I promise you will see a huge improvement. Stock US 333hp vs an Est. 365hp Euro Headers - Activewerks $895 - Saves about 5lbs off OEM / HP Increase 7hp RPI Exhaust - $995 - Saves 17lbs off OEM Cold Air Intake - AFE - $495 / HP Increase 5hp Power Pulley Kit - Turner - $265 / HP Increase 8hp Tune - Activewerks $495 / HP Increase 10 hp Go to a 4.10 Rear Diff. - $3,000 Installed *Highly Recommended* Dump the stock wheels the weight 31lbs each, this will save you another 40lbs You could save another 40lbs by replacing your seats with Recaros Titans-7's = 18.25lbs or APEX's = 19lbs |
