Homebrew XR6T FMIC on a Z27ag

After seeing JGirl post on the RColt forums on how to plumb a XR6 cooler on a Colt I was super keen.
Mainly because it was black, easy to do and didn't require any cutting (well nothing major).
http://www.rcolt.com/showthread.php?3070-J-Girl-s-intercooler-set-up




Bought myself 0.5M of 5ply Silicone pipe that is used on trucks (2.25").
Stupid mistake was picking 2.25" as my stock piping size is 2"
Would of been smarter to stick with 2" and use silicone reduces on the FMIC from 2.25" to 2"







I also got about 0.5M of 2.25" straight pipe, 1x45degree bend and i think 5x90degree bends.
Mate help me weld them up with a bead on the pipes to stop any hose clamps coming off


I aimed to connect it to the stock 90degree bend in the engine bay.










The new ground cable i have for the horn.




You can see where i have relocated the horn to.

You can kind of make out the top pipe running along top of the FMIC.
Runs into a 45degree bend then into a sharp 90degree








The stock rubber pipe that use to run to the stock FMIC was trimmed back to allow for a 1.75" to a 2.25" (if i remember correctly OR it was a 2" to a 2.25" enlarger)

I used zip ties to hold it for over a year...No problems.





I have now added some self tappers in the bottom of the FMIC and one in the top.

I had to angle grind the stock horn bracket off the crash bar. And trim some bumper off.

If i had to do it again i would make the bottom FMIC inlet straight. Cut off the weird 45 degree inlet and get someone to re-weld it as a straight pipe. Would allow for a easier install without bumper trimming.

BA/BF-XR6T = 368mmL x 178mmH x 51mmD = 3,340.704 cm3

"At a core size of 370 x 175 x 60mm, they’re relatively compact but have well-shaped alloy end tanks. For people wondering overall size, they’re 620 x 270 X 60 cm to the extremities. Inlet/outlet tube size is 58mm (hose ID)."

BA/BF-F6 = estimate based on being 50% bigger than the XR6T = 5,011.056 cm3

Right now – and probably for the next few years – there’s a helluva bargain to be had.

I’ve bought one to put on the shelf and I highly recommend that anyone else into useable road performance does so too. And what should you buy? At least one of all those BA and BF Ford Falcon XR6 intercoolers that are being flogged-off on Australian eBay, commonly priced from about fifty bucks.

Yes, from fifty bucks.

Now maybe the people who want far in excess of the Falcon’s standard 240kW have an urgent need to replace these Garret-cored, bar-and-plate intercoolers with something far better, but for people who are happy to drive a car with performance not limited by wheelspin, these intercoolers look perfect. Being an all-welded design, they’d also be dead-easy to jacket with aluminium sheet, making them water/air intercooler cores. At a core size of 370 x 175 x 60mm, they’re relatively compact but have well-shaped alloy end tanks. For people wondering overall size, they’re 620 x 270 X 60 cm to the extremities. Inlet/outlet tube size is 58mm (hose ID).

Even if you consider the time and labour to fold up new end tanks from sheet aluminium and pay someone to TIG them to the original core, you’re still talking an excellent intercooler for the price.

The one I bought came with all its hoses and clamps – also very useful when you’re plumbing any intercooler into place.

Without having done any flow or temperature testing, but looking at the core and assessing the original application, I’d be happy running at least 200kW through them – more, eg 250kW – with a good water spray.
