could i use flex pipe for my intercooler piping? or is the flex pipe not air tite? anywho, i just scored a 89 toyota supra intercooler for 14 bucks and plan on using it. The intercooler has both the inlet and outlet on the same side. But it's aluminum and it's too damn expensive to get one of the pipes cut and rewelded to the other side. so im was wondering if i could just use flex pipe to curve around the back of the intercooler to the other side of the car. thanks.

 

Flex-pipe doesn't bend that much, just enough to releive stress on the exhaust system so nothing comes loose and so on. Since you were able to pick that i/c up for such a low price, just get an estimate on what it would cost to make it suitable (cut and re-weld) for your application.

 

Flex pipes aren't air tight, at least that's what I read from a thread about them in the welding and fab forum. 90 degree silicon elbows are another option, but one 90 degree elbow costs around $40. You can try using aluminum elbows, but just use straight hoses to connect them all.

I still think the best thing to do is just get all the stuff welded together. Find out how many bends you'll need and buy some from atpturbo. Then cut it to the correct length and use some duct tape to hold them all together. Take it a local welding shop that can weld aluminum and have them weld it all together.
