G55 Modifications

Hello,

A relative of mine has a 2010 G55 that he wants to modify,

the car currently has a K2 Kleemann which is basically ecu upgrade, pulley and drop in filters with Kleemann headers and CM30 pump.

He want to put some additional mods to gain more power:

I've been eyeing on the following:

Carbon Intake
CF Python tubes ( dont know if they fit )
82MM throttle body

What have I got to do for cooling upgrades to reduce the likely chance of heat soak,

I know H/E is a must, I couldnt find any and does the ones offered for the E55 fit for the G55 ?

Are we on the right path ? Are there any modifications we should remove from the above list ? Are the phenolic spacers good ?

I think you're on the right path. After the pulley, and headers, my next to do mods would of been the 82MM TB and then the CF airbox. Then top it off when a custom dyno tune! How about the exhaust? Time to chop chop

Good luck!

What do you recommend with the exhaust, secondaries removed, high flow secondaries, resonator remove with straight pipe?

Exactly

Or you could put the high flow cats close to the headers and then you can put a x pipe where the secondary cats used to be.

What's the rule of thumb, put cats close to or farther away from the headers for exhaust velocity peak performance?

What is the best 82mm throttle body and how much do they usually go for.

Not to be rude, but why are you posting this in an E55/E63 forum, and not the appropriate G55 forum??

I've posted it in the W211 forum because the G55 forum has very low activity and not many modify their cars, second of all we share the same engine with the E55 and the E55 W211 forum is pretty active.

+1. It's the reason why I post in this section as well. CLS55 shares the same motor and 90% of the 55 motor traffic is in the W211 section. I have gotten the best advice and insight from this section.

Look for bruce from TTM for that, you won't regret it at all, it will cost you something around 1400 - 1600 USD not sure exactly how much, it is complete one and you don't need to modify anything

There should be a 55k motor section...
