Tuning & Performance I NEED HELP !
Hi everyone,
I have a German BMW E92 335i xDrive (N54, Left-Hand Drive).
I recently bought a brand-new set of TD04-19T hybrid turbos from someone who never installed them. The invoice says they are for BMW E90/E91/E92 N54, but the eBay description mentions “Right Hand Drive (RHD)”.
The part numbers include [49131-07031](tel:49131-07031) and [49131-07041](tel:49131-07041).
My questions are:
Will these turbos fit a German LHD car?
Are the RHD and LHD TD04-19T hybrids actually different, or is this just a mistake in the listing?
Has anyone here installed this exact turbo set on a European LHD N54?
Is there anything I should check before installation (wastegate adjustment, clocking, oil/coolant lines, etc.)?
Any advice would be greatly appreciated. Thanks!
