Lightbulb DIY/JUNKYARD FM-Intercoolers

I wanted to know peoples opinion on using a used intercooler from a truck/car. For example I came across two Isuzu NPR intercoolers on eBay. Thought to myself it would make a nice FMIC rig for any turbo application. I'm sure I'd have to find out what the CFMs are on it and compare it to other aftermarket ones. Iím reaching here, but would someone have those specs available?

Post way guys, let me know your thoughts on this.

It isn't the IC itself that is the problem....It's the piping and the rest of the hardware that is.
If you think you can figure out the piping and all that...go for it.

Exactly. Sourcing a IC isnt a prob but the piping it. Also, the size of the IC should be considered since you will probably chop the bumper beam up.

You can buy new cores pretty cheap and make your own IC if you have access to a pipe bender. The other option would be to buy mandrel bent pieces separately and weld them together to make it work. If you've got the talent and the tools to do it, you can save some $$.

Another popular DIY intercooler is the one from the Ford Powerstroke diesels.

In all the situations I have been in where ppl have made thier own I/C's for DSM's, turbo civics, ect. it has always turned out to be more of a pain that is worth. It also cost's more money in the long run.

I used to believe making everything yourself was a good idea, but sometimes it just not worth it, like in this case...

Good point. My buddy had a side mount DSM intercooler on his turbo Civic that he "made" himself with various fittings, PVC and metal piping. It has always given him a tough time because the fittings keep popping off under boost.

I always thought, though, that if he took his cobbled-together creation to a good muffler shop that they could bend and weld pipes together to make a more fullproof set of piping. I guess it's just a case of having access to the right tools (which most people don't) to do the job right.

You really should not try to piece together your own IC unless you've got a pretty good background in automotive science or metalworking or a good grasp of some fluids concepts.

With complete used FMIC's+ piping +shortram intakes going for less than 1000, it's not really worth the time and lost power with a DIY IC job.

Basically, DIY stuff in general is only good for applications where the economy of scale is lacking. DSM's and Subaru's have tons of cheap parts available, I would only use a junkyard IC if I was say putting together a turbo MR-S kit from scratch, since the ones sold are like 10 grand.

Well, right off the bat, the endtank inlet and outlets are in the wrong position. If you are handy with metal fabrication, I suppose anything is possible, the question then becomes, s it worth it ?

Where did you get the idea that the inlet and outlet are in the wrong position? I've built and designed a number of IC's in the past, and all I can come up with is that the pic doesn't show enough to make a decision. He could have internal diffusers for all we know.

With that said, one can make an FMIC for a WRX, it's just a lot of work. Where a Honda IC will have about 4' of piping, the standard WRX FMIC has around 6'. Here's a secret though..... If you start with a CAI, then a large part of your plumbing is taken care of right away. I learned that from the Honda world.
