haha been a while since someone replied in this post. i just have a few questions for those of you who have successfully pulled off custom piping. first of all, could any of you guys be nice enough to post what pieces you used and what length you used? (90 degree bend, 6 inches, etc.) be as specific as you can please. pictures would be great too. thanks so much in advance.

Every car is going to be different too. Depends on the turbo you have, what kind of outlet (pipe) and size it uses. What size intercooler you have, where the outlets are located, what size they are, and so on. Also what kind of Throttle body elbow you choose. Also if you are using a 2g/3g Maf or a Blow Through Maf sensor. What kind of BOV you use and where it needs to mount. Also what kind of intake pipe you are running, because the intercooler pipes need to clear it. If you are using a Maf on the intake you need to have a BOV return pipe on it, obviously. So the BOV flange will need to be welded in a spot where the recirculation pipe can be routed without interference. Sure you could try to mimic someones setup closely but unless you have an identical setup there is not going to be a set list of parts.

If you have an intercooler with inlets facing the rear of the car you can do simple short route pipes. For the intercooler to TB pipe you really only need a 45 degree bend coming from the IC and a 90 degree bend for a TB Elbow. Then about 2ft or so of piping along with a TB flange and a BOV flange.

Depending on your turbo the outlet pipe will be up to you. You can probably get away with a 45 degree bend coming from the IC, the same as the other side. Then a 90 degree bend towards the turbo. Like I said depending on the turbo your outlet pipe location will be different but with the pipe from the IC pipe right there you can just match them up with whatever bend or straight connector or reducer you need.

If you have a side to side style intercooler like me it gets more complicated. I would have preferred short route but this is what I have. For my IC to TB pipe it will have a 45 degree bend on the TB welded to a straight piece that ends right above where the stock battery fits. It will then 90 degree down through a hole I have to cut. It will then have another 90 Degree bend going forwards to the front of the car. Yet another 90 Degree bend will be welded to that and end right at the IC outlet. Yes there are 3 90 degree bends and a 45 degree bend in the UICP alone, if someone knows a better way short of modifying the IC please chime in.

The Turbo to IC pipe is not quite as bad. It will come out of the IC and make 1 180 degree bend around the core support and then run under the turbo right behind the radiator. It will end right below the compressor housing and connect to a 2G style J-Pipe on the 16G with a single 90 Degree connector.

I know this an Ultra long route piping and will cost me a little extra power but oh well. It will have minimal connectors to blow off and will be all 2.5" piping.

ok i found out more specifics for my exact setup. i beliiieve i have the following:
-a fuso intercooler? small npr

-a 2g throttle elbow
-14b

so what exactly would i need? im thinking of just getting a +$100 pipe kit off ebay. the problem is i dont know what bends i will not have enough of.

by the way both the inlets face towards the engine and are at the very bottom of the intercooler.

Hey that looks like my front bumper... except my IC isn't hung upside down ! Just kidding man. Why do you want to change it. Does it still use alot of stock pieces??

nah i have custom ic pipes right now. but theyre really poorly made. the last bend on the upper ic pipe is so bad that it scrape on the floor when i go over a bump. hehe.

so i pulled out my old upper ic pipe today, and it is destroyed. haha. there were so many dents and whatnot, most of the pipe is no longer a circle, i think its taken more of an oval shape to it.

so looking at my lower ic pipe left me kinda confused. should this be a smaller diameter pipe? and what bends? i think the way it is now it goes from partially the stock ic piping to 2.5. its pretty banged up too so ill have to redo that one too.

I had the sbr race 1g kit on my car for a day (borrowed it from my brother). I had to move the radiator to the drivers side a little and do some minor trimming. I also had to bend the mounting bracket on the intercooler a bit. It actually fits pretty well. The inlet pipe should ideally be angled inward about 15-20 degrees for a galant and be about 2-3" shorter, for clearance. I have a jdm bumper so I don't have any idea how it would fit with a us bumper.

here is my "custom" piping, and what i would say is the best way to mount an NPR
oh, by the way... the ic is level, it's the car thats not

haha. that makes so much more sense. i was just thinking the other day, why would you point the inlets down? makes it so much harder. maybe ill have to look into that. what are you using to hold the ic up? just a few brackets?

I have these 2. I can take more if someone wants to see something specific. I tried to get a good shot that showed the piping behing the headlight on the pass side, but there isn't much room. The NPR had four mounting tabs on it, i just cut the bumper support and drilled holes to match and then cut off the bottom tabs on the IC. I did need to trim the headlight bracket quite a bit, i was a bit worried about it not having enough support and shaking at speed, but after i bolted the headlight in, it firmed it right up.

some bumper hacking was required, some hacking of thin metal under both headlights (absolutely nothing was supported by this metal)

three steel 90 degree mandrel bends, two 2.5" steel straight pieces (one for bov), straight 2.5" silicon connectors, one 2.5" silicon 90 elbow, one 2.5" silicon 45 degree elbow, NT throttle body, gm maf in blow though with 3.25" to 2.5" silicon reducers, custom tdo5 compressor housing, t-bolt clamps.


















I finally used this wrap I had lying around ($15 for 50 ft)

hope this helps. i'ts 2.75'' post ic and 2.5 pre ic. i made it this way in anticipation of a manifold and a large turbo

You can do short route. It is easy if you don't mind putting a bit of work into it.

Needed:

Any 1g 2.5in "short route" FMIC pipe kit (I used lucas english's kit)
Any 1g "short route" FMIC

Modification you need to do to your VR4?
- Use torch/plasma cutter to remove material from the front sheetmetal around the bottom left/right of each side of your radiator area. This allows the short route pipes room to make it. The passenger side needs very little removed, you can squeeze the 2.5" pipe easily by bending in the superficial fins in the end of your radiator. The drivers side needs a bit more material taken off to allow piping to sneak by. But still this is very minimal.

-The 1g 14b/16g outlet pipe needs to be fabbed a bit to keep it from hitting the much closer vr4 radiator.

-Bumper support may need cut in order to fit thicker intercoolers. I cut out the middle of mine to retain fog lights nicely.


Here are a few pictures of the setup. I did it for pretty cheap (800ish bucks) and it is by far the "shortest" and best imo FMIC setup you can do for your VR4

I went the "long route" with my car because the intercooler fired that way, it would have been ridiculous to do it any other way...

this is a basic Dave Brode core, with custom 2.5 inch "cold side" i ended up having to have the hot side modified to come out straight rather then over the manifold like stock galants, look at the pics it will be obvious why. these pics are just the mock up of the pipes they are all just tack welded. as you can see in the last pic i built an intake as-well ( by the time that was done the piping already started to get surface rust on them) in a few more days all the piping is going to the powder coater anyway.

I switched to a N/T throttleMe and my friend did the new I/C piping setup ourselves...we spent around $300 in pipes, tbolt clamps and silicon couplers. I went with a short route setup and I believe we used the following:

(3) 90* mandrel bend pipes
(1) U bend pipe
(2-3) straight pipes

All pipes are 2.5" in diamter.

I bought my silicon couplers from ATP turbo online and my Tbolt clamps I bought locally. It took a good FULL day to finish the piping. It wasnt that hard actually...but I guess it helps when you have somebody who has done alot of custom I/C piping setups.

Here are a couple pics of the current setup:




I also did my I/C piping on my 96 Galant:



91 GVR4 1948/2000

2002 Montero Limited

Here was the setup I just ran. Trimed the rad a bit but didnt move it.
Core is a bar and plate 9?x26x3.5.
piping is 2.5 mild steel (hey I did it myself)
2g t body elbow.





I will try to get some more pics with the bumper off soon if someone wants them. Erik O.
