Spent a lot of my day installing the new FMIC piping. Its the ebay piping that I purchased in the other thread. (http://www.audizine.com/forum/showthread.php/470755-Anyone-use-this-FMIC-piping-kit)

Overall, I regret going from 2.5" to 2" piping, I think my spool up may be slower. Is this even possible with a smaller piping?

This FMIC piping kit is not for you if your FMIC ends are too low. I ran into an issue where the piping was not high enough under the hood, had to rig some more piping in that I really did not want to do because it defeated the whole purpose of simplifying my FMIC. If you look at my FMIC , your ends must be about 3" higher to make this piping work.

For the grill inserts, I bought some "expanded mesh" at Home Depot for $20, plasti-dipped it, cut it, zip tied it in. I am happy with the way this came out.


Ive also taken some pictures for people that want to know how much bumper I had to hack off to get my 30x3x10" FMIC to fit.

All shots were taken with the GoPro2

Nice looks good. Now I know what to look for at Home Depot because they have no clue what I'm talking about.

Too large and/or too small piping increases lag. You need to find the in between. With your setup, 2.25" hot side and 2.5" cold side would be good. But I'm sure you already knew that. Think about blowing through a straw. Too small, and it takes forever to get the air through. Too large, and there is basically no velocity in air flow. Same thing with amount of piping with it taking the time for the flow to reach the other end, accompanied by the piping size playing a huge factor.

With my setup, I am using the stock intercooler 2" piping to the Boost Factory SMIC that has a 2.25" inlet (used transition 90* coupler), then changed the outlet and throttle body pipe to 2.5". This is not optimal for my setup, just as yours is not for yours. But, it will get the job done and best I can do at the moment.

But good job on the DIY grills. Looks really good. I need to redo mine, but am rather lazy. I ordered mine from the link you sent me a while back. The local Home Depot didn't have any in stock, so I just had it shipped.

I am going to guess that is why Fred went with 2.25" hot side and 2.5" cold side pipe setup when he designed the ER Comp Kits. lol

I was about to say I could ship you the rest that I have left, which might be enough for some grills but I guess you are good to go!

Kinda surprised by the amount of cutting you had to do to the rebar to make it fit. I was under the impression that with an s4 bumper and 3 inch deep intercooler there should be little to no cutting.

looks great. What did you use to paint the piping?

I used my left over Eastwood radiator paint. I also touched up my existing FMIC core as you can tell it had a few chips in the paint in the first pics.

How much of a difference will it make running piping that is too small? I have basically the same setup (2871r elim, 630 mafless) with a treadstone tr8.

I got 2" custom bent piping from an abd kit for free from a friend and ideally want to use that. Is it worth it to step up to larger size piping?

Just a side note when I did my FMIC the SAI was and can be In the way on the 2000+ models is when I think they started using it. warning all it makes piping in a pain.

NIce write up. [up]

You will be fine if your not trying to runt he turbo at its max flow.

Next time you need that little bit of expanded metal pm me im a metal fabricator ill send you any size piece up to 24"x24" for free if you pay shipping which would be much cheaper

Once I drop my rods in I plan on running it at 23-25 psi. What would you say is its max flow?

I noticed a slight loss in power going from 2.5" to 2" piping.

That's kind of a trick question to answer since boost pressure doesn't directly correlate with airflow, unless you also know the speed that the impeller is rotating at.... The simple answer is that you will be able to achieve 23-25 PSIG with 2" IC piping (assuming that you could with 2.5" IC piping too), but your flow will be reduced versus running 23-25 PSIG through 2.25" or 2.5" diameter IC piping. How much will your flow be reduced? Hard to say. From Biketsai's experience, the reduction will be noticible. Probably best to go with at least 2.25" IC piping at a minimum.

If there is some loss it will be in the higher rpm but only if the turbo is flowing more air then the pipe can handle. The best size piping for that turbo is 2.25" on the hot side and the same or 2.5" on the cold side for getting the max power out of the turbo.

Great work, looks brilliant.
