I dont know if anybody made a thread like this, i didnt have time to search because im at work.

I want everybody that has pic's of the front mount intercooler piping setup to post them, so i can get an idea of how you can do the piping in different ways. If you can, include what kind of pipes they are (steel, aluminum), how many different pipes you used ( straight pipes, u-bends, donuts, etc. etc. etc.) and the degree piping you used. I think this will help out more then just me but anybody in general trying to do the IC piping themselves.

i am too lazy to find it, but if you look in the members rides section and search for my user name, you will see my pics of the installation of the hybrid FMIC setup. It shows you how all the pipes are routed.

I ran my piping from the left side of the intercooler over the top to the right side. (view atachment) If you do it this way be sure not to get in the way of the head light poping up. I used steel exhaust piping.

here's mine. I have the cold pipe behind the radiator. It'll be easier to redo just one side of the piping than two once I get a greddy manifold.

I hadn't even noticed that the first time I saw it... that really makes a lot of since. You minimize your bends that way too... I can imagine all of the tight radius 90's and 180's involved in coming from one side reduce flow rates.

So is it possible to not have to relocate the battery with a fmic setup?

Yes, I didn't relocate mine. Your going to need a smaller battery tho. I have one of the Odessey batteries in mine as you can see by the pic.

Yeah, but why wouldn't you. Especially after the added weight of the RB motor.

I just did my custom piping today. I got some group buy intercooler and it fits my 240 opening perfectly. I will post some pictures tomorrow. It took me 4 hours which is pretty fast imo to do it. I got 5 90 degree bends 1 45 degree and 1 straight pipe. I had 1 90 and the 1 straight left over. I reused someof the stock piping. I went across the radiator with my hot pipe like some of you guys. I'll get some pics up tomorrow. hope this helps a bit. I might try later to cut out some of the couplers and use more pipes but I didn't used too man I think I used 6 total.

This is what i've been working on today, since i got my intake plenum.









Basically, s14 Greddy vspl, with tophat intake plenum. All the pipes pretty much fit, The hotpipe will fit pretty darn well. The cold pipe will need a 45 degree coupler and besides that it fits great in conjuction with the tophat rb25 intake plenum.

I painted the fmic black to get a little sleeper/stealthness and to avoid gettin cops attention as my buddy's neo6 has gotten the ref ticket.

That paint looks crazy thick on that IC. I think most people just spray 1-2 light coats and call it a day. I don't think it'll be much use as a means to cool the intake charge if you've killed the heat transfer with a thick coat like that...

Yeah you use the radiator paint, my cousin did it on his civic and when we had it on the dyno (keep in mind not a lot of air moving across IC on the dyno even with the fan blowing) his intake air temps were not much higher if at all then when it was unpainted. Stealthy/Sleeper and still gets the job done right....

Thumbs up in my book.

I'd keep my bling bling so bad...but cops around the bay suck ...california emissions suck. SF cops are cool though...to a point.

These are older pics, I'll get some new new ones up in the next day or two. It's finished under the hood, except for the dump pipe coming off my turbo.
