I have been driving my BMW E60 525i with N52 engine for more than a year now. So far I have not encountered any serious problem related to this model. My grave concern was the makan minyak hitam issue but after more than 60000km drive with engine oil change (Shell Helix Ultra 5W-40) every 10000km, I'm very satisfied with my JOY :top: :rock:
But after a while, I started to get itchy
wanted to do something different to my already perfect (well, at least to me) ride. Knowing the fact that there is about 218bhp under the hood, I can't help but to think of ways to further ENHANCE its performance hence this thread. Maybe the input from all the forumers (no matter you are E60 owner or not) can help to shed some lights to those who want to add extra hp :wink:
Apart from aesthetic enhancement - Hamann front lip (sudah pecah.. no more coz got problem going into carparks with steep slope), Hamann diffuser (to accommodate my quad exhaust), Angel iBright v3 white angel eye ring marker, chrome front grille, some customised stickers...... I feel like giving it extra horsepower. So what do you think?
So far I have only added
Remus Quad Exhaust! With significant backpressure reduction, my E60's pick up and acceleration has improved compared to when using stock twin exhaust :top: sounds nicer ie. deep sporty yet non-intrusive sound. It is claimed that performance gain as high as 3-5% is achievable (Factors like car make, model, engine size, exhaust restriction and rev ranges play an important role).
So... what else can be done in order to add extra oommpphhhh??? I have actually listed a few:
1)
Supercharger - ESS, G-Power, etc... but it's way out of my league. I can't afford these stuff which easily cost more than 5 digits
2)
Light weight crank pulley - last time I checked, there was no pulley available for E60 with
N52 engine. But for
M54 engine got lah (take note). Gain of 10% is claimed!
3)
Exhaust Manifold - Have been looking around for a custom exhaust shop that can convince me to do this job as I don't want any potential problem. so far I have listed a few shops such as
JFA & Torque Gear (Sunway) but haven't got time to approach them yet. Places like Xin Exhaust advertise for about RM1800 for stainless steel (I wonder what grade) but I am sceptical about this shop. Anyone can share some info here? What is the performance after changing the manifold?
4)
ECU Remap - I think this has been discussed extensively everywhere by almost everyone. My research conclude that there are many BMW specialists around Klang Valley that can get this job done. Damage? RM2500-4500 (different place quotes different price)
performance gain about 5-10%
P.S: for those who want to do re-mapping, do all the modifications before the re-mapping ok? So they can do dyno on your car before determining the optimum setting for your car :top: this is what told by some friends of mine
5)
Drilled Slot Front & Rear Brake Rotors - well, no gain in power but definitely will improve your braking. Cross drilled and slotted rotors are engineered to provide maximum heat dissipation for dependable and safe braking under extreme braking conditions. The combination of the cross drilled holes and slots enables the braking surface to be cleaner thus providing improved friction bite under wet and dry conditions. Also don't forget to replace the stock rubber brake hose with
Goodridge Stainless Steel Brake Hose (lifetime warranty). This brand is said to be the OEM supplier for Brembo performance brake kit. Cost about RM500++
6)
Air Intake - normally our stock air filter does not offer the optimum performance to our car. That is why companies like K&N and BMC offer drop-in air filter to replace factory stock, which in turn offers small gain in power. Of course, for more performance... high end stuff like
Gruppe M which cost somewhere in the region of RM4-5k can offer the desired result. But it's too expensive (to me). That is why I have ordered this
aFe Magnum FORCE Stage 2 Cold Air Intake System for E60 525i and 530i (year 2006-) from the US. FYI, the product number is #54-11042 so those who are interested. Have been googling around and so far the feedback has been encouraging. That is why I have ordered one unit of this from a shop in US... damage? RM1700 including custom and tax... sigh! Should have asked the shop to declare lower value in order to save the tax... below is the picture
Basically that's all I know for the moment... any input will be highly appreciated. Hopefully this discussion will serve as the base for those who want to beautify and enhance their current ride! :rock:
