Homemade FMIC (Even bigger than AA and HPF) for $300 - BMW 3-Series (E90 E92) Forum

Big Tom · 09-02-2010, 03:48 PM

Why buy one of those overpriced FMIC's out there for ~$1000 when you can buy a even bigger one for $300? (All hoses and pipes included)

The IC it self costs $240 and the pipes and silicone hoses costs $60 from a shop here in Sweden.

The core is 18"x12"x4" and the in and outlets are 3", which makes this to the biggest IC with the biggest in and outlets available to the N54 engine.

The core has an area of 14158 cm3.

As a comparsion, here's some of the most common and biggest FMIC's out there right now:

Helix: 11917 cm3
Stett: 10160 cm3
HPF: 13282 cm3
AA: 11085 cm3

The stock IC is: 7620 cm3.

The installation was quite easy. Just like the AA IC you just have to trim the stock IC shroud away.

One thing that worried me a bit in the beginning was if the boost response maybe could suffer from this HUGE IC...? But, nope! She was still as responsive @ WOT as before.

I took her for a ride when the installation was done, and WOW what a beast she became! The power @ high rpm's was amazing!

Here's where I bought it from: http://shop.klracing.se/sv/artiklar/...akanslutn.html

DieselDiner · 09-02-2010, 03:55 PM

Wow. Do you have any means of measuring the pressure loss with this monster?

forza1976 · 09-02-2010, 03:55 PM

damn, that is a monster compared to the stock unit...

Nice DIY!

kjrulz · 09-02-2010, 03:56 PM

Please dyno and/or datalog so to see if results actually match up to competitors.

ar design · 09-02-2010, 04:16 PM

Fin count/density looks to be VERY low on that core.

kjrulz · 09-02-2010, 04:16 PM

17.7" x 12" x 4"

give or take...wow.

Ferre86 · 09-02-2010, 04:18 PM

Mr. 5 · 09-02-2010, 04:21 PM

Grat job!

Dvdman · 09-02-2010, 04:24 PM

Great work..

francisomar · 09-02-2010, 04:26 PM

Good find, hope it's all worth it and a less expensive solution for us the ones that haven't upgraded yet the intercoolers.

Mr. 5 · 09-02-2010, 04:27 PM

Here's yours:

Here's mine

Great Job man!

s.myrr · 09-02-2010, 04:29 PM

Holy crap! Nice DIY!

Big Tom · 09-02-2010, 04:31 PM

Yep, they're almost the same IC's!

The only differences is that the thickness is 4" on mine vs AA 3.5".
And the connection pipes is 3" on mine vs 2.5" on the AA.
