Hey guys, I’m looking to upgrade my turbos on my G80 to the pure turbos. Although right now I’m running just e50 and catless down pipes and intakes. What mods do I need to support upgraded turbos? Do I need upgraded manifold and charge pipes? I’m looking at probably just do E 50 on upgraded turbos.

Depends on how your power level goals. Pures can support over 900WHP. I would think at the very least you should add a drop in LPFP.

Trans... if you want to push them to the limit.

The upgrades will depend on the power goals.

I recommend you start by picking a custom tuner and talking to them about your goals. They will recommend what to upgrade for a safe and reliable build.

You can do E40-50 on stock fuel system with hybrid turbos. No other bolt ons needed, but you do need a custom tune since bigger turbos demand more fueling from the DI.

Right now I’m dialing in Paul’s Flex tune for upgraded turbos, which gives full power at E40-50, but can run up to E85 with limited boost (to keep fuel supply happy).

you should also upgrade the spark plugs to NGK and gap them correctly

[TopJimmy]

Or re-gap your OEM/BMW plugs since they are NGKs, as long as they are clean and were used for

Hmm i was not aware its okay to recap the stock ones, G80/F80Paul keeps telling me to buy new ones

[chris3g]

The oem plugs are ngk 96206, it’s the same plug except it says bmw on it.

Maybe he is saying to replace them since they have some miles on them. It’s ideal for an engine like this to change often. Especially with upgraded power levels. I’m going to change mine every 10k. Cheap insurance.

if you are looking for max effort, you should consider an upgraded LPFP (maybe pfs drop in) and port injection. more importantly work with a knowledgeable tuner who can help you with the right set up to meet your goals and budget.

here is some more information on S58 and power levels.

im FBO right now with E30

I will be upgrading to a custom map and E50

After that, I will upgrade my turbos.

Then go PI and another custom map

its going to take a year or so but i hope by the end i will have the comparison between all the different stages with the pros and cons of each
