Rust inside steel Begi intercooler pipes
I bought a used Begi intercooler and piping kit a while back. Three years later I am finally installing turbo and there is some light rust visible on the ID's of the steel piping. I would hate to suck any rust particles into my engine. I'm looking for tips on cleaning the ID of this piping. I have been looking for a pipe brush big enough to clean the 2" tubing. Maybe some Evaporust?

FLEX-HONE TOOL Flexible Cyl Hone,Bore Dia.2in,120 Grit - Flexible Cylinder Hones - 2ZYX5|BC20012 - Grainger Industrial Supply Looks like there is one for $31 shipped on ebay.
Poke around ebay and there's similar bore brushes for cheaper. Or a flexible drill shaft with a wire wheel at the end.

Yes, its the older steel with couplers only. I have small flexible hone like the one linked. It doesn't work around the bends.
I would prefer Aluminum tubes too, but I have a complete set of intercooler tubes already fabbed and that fit. I'm not redoing all that right now.
Do these pipes rust when installed in the car? My 1.8t jetta always has a thin film of oil in the intercooler pipes so I figured I would get a similar coating on my Miata pipes. I was planning to just stick a breather filter on the turbo side of the valve cover for now, but might need to run it to the turbo inlet pipe so I can get some oil vapor to keep the pipe ID's shiny.
The outside powdercoating sucks. It is flaking off in several places.

According to Corky Bell:
"Is rust in the intercooler tubes ok?
Rust in a mild steel intercooler tubes is completely normal. And OK. It will not hurt the motor and result in damage. If a piece of rust goes thru the motor, it will vaporize before it can do any harm. No damage will result from rust in an intercooler tube. "

If you're really worried about it, the above suggestions for ALU replacements sound like your best bet.

I just want to clean the rust on that has accumulated from storage. After that I'm not to worried about a thin film of rust.
Someone at work suggested that I try pushing a ball of steel wool through a couple of times and then rinse it out good. I will give it a try this weekend.

I ended up getting a $1.99 toilet brush at wally world and it worked great. I was going to spend $15 on a dryer lint brush that could reach 4 ft, but the toilet brush worked great. Some WD-40 and a couple of passes of this brush and I got it all shiny and clean.
