Hello fellas,

I’ve got my eye on a 2007 330d with the M57N2 engine, and I’m planning on doing quite a lot in regards to performance.

First off will be the obvious, deleted, downpipe and a tune, but then I’ll gradually want to do a bit more, upgraded FMIC, injectors, fuel pump, turbo etc.

I’ve checked some forums, and people recommend the 535d injectors as an upgrade for the pre lci 330ds, but checking realoem, shows the same item number on both the 330d and 535d injectors. Does anyone know the differences are between the two? Considering they have the same item number (13537809194).

Also, what would you guys recommend for the whole upgraded fuel supply system, M50d fuel supply system?

There are so many things you're going to do before you gotta worry about more fuel. You've only got 1 turbo, lol. That's where you'll be spending some $$$.

So where do you recommend I start, better flowing exhaust system and hybrid turbos?

You've got a single turbo on there now. I'd look to see what upgrades are out there for that and make a plan.

First thing you need to do is make sure the maintenance is up to snuff, then worry about modifying. See if you like a simple delete/tune and go from there.
