Will new intercoolers for M3 or N55 fit N54? - BMW 3-Series (E90 E92) Forum

stressdoc · 09-02-2009, 10:48 AM

Anyone have a look at the FMIC bits for the upcoming M3 and N55 applications? Any chance we might be able to swap our little N54 units for an improved OEM one? I would guess that BMW Perf would be all over this if a fit is feasible.

Not aware of an intercooler for the M3...

Chances are, the intercooler for the N55 will also be crap.

The N55 pictures show a bigger 11 row FMIC, i suppose it is quite the same as the one in the X6 N54

But I saw that the piping system changed a bit?! maybe less restriction?

I think that the X6 3.5i intercooler would be the one to replace N54 intercooler with, or even the 740i intercooler. There is a thread on this forum with more details, there are not many modifications to be made to the X6 in order to fit.

Here is an idea: we should donate $10 per forum member to a trusted member who has fabrication skills and background in order to build a DIY kit to modify the X6 intercooler mountings/ducts to fit the 335i. The X6 intercooler costs about $200, I think that with $1000 cash someone could prototype such a kit.

Then we could buy an X6 intercooler and this ($100) modification kit and have a nice big OEM intercooler.

That is the idea, $200 OEM FMIC, simple plumbing changes, and whiffo-presto, all the IC cooling we need for moderate use. Hoping BMW Perf will do this for us and keep price under $500, including an OEM catch-can.

I wish! Knowing BMW, probably no chance.

Why the infatuation with oem IC? Just go custom or aftermarket.

not necessarily, granted its a bmw part, but its not original on the particular car; im sure they would give the same treatment as aftermarket parts if a problem were to arise
