---ok yes i searched but couldnt get exactly what i wanted, if you know where more info is please post a link---

my question is for all thosw who have done DIY Intercooler piping - first of all do you have any good pics i can use for refrence and second does any have an exact blueprint of the process or atleast the best size/lenghts/dimentions to use as a refrence...
what i have: 95 s14 with s14 SR (vtc) motor / standard
i need to get this together in kind of a hurry so any and all help would be appreaciated..thanks

There really isnt going to be a right up on how to do this since intercoolers have different dimension, and different endtank locations.
When I made mine I went to truck supply place, and bought 2.5" 90 degree mandrel bend with some silcon that they sold by the foot. If you want to make it easier then buy some 45 degree bends also.
Mount your intercooler first, and then just go from them with the 90's, and mock everything up, and begin cutting.

I did it pretty much the same way. I ordered some 18 gauge 90 degree angles and u-bends from RRE and/or JC Whitney. Then I cut and fit, using duct tape to hold the pipes together until I could tack them and then weld them.

I ran a npr intercooler on a KA-T with pipes running through the firewall, next to the radiator.

You silly monkey, that's not the firewall!

the hot pipe and cold pipe are pretty much going to always be the same(depending on the chassis), so if you could get dimensions for those that might save some time. But as other members have mentioned everything else is really going to depend on the dimensions of your IC.

thanks everyone for the replies... well the fmic is already in the car and operating but when ever i get on it too hard the pipe seems to blow off so i first wanted to buy a pipe kit but on ebay they are 250 + 80shipping which seems to be too much for some alum tubing ...so i was hopeing someone else might be able to tell me exactly what i need....my i/c dimentions are approx. 24x12x3 with endtanks like a blitz fmic(i had a blitz fmic on a s13 i had before and sold) but now its on a s14 with a s14 motor so i know that the throttle body is in a different location...if that helps any one to give me some detailed info i would really appreaciate it...thanks

You either need some ghetro "maximum hold" hair spray or some beaded intercooler pipes.

But seriously, spraying hair spray on the pipes then putting the couplers on and tightening them with a small rachet will work. Don't really crank them down, because you can and will destroy the worm drive portion. Just get them tighter than you can with a screwdriver.

Roughing up the pipes with some rough sandpaper helps as well. I'd let everything dry about 30 mins before you go and boost it, but it should be good to go after that.

I have a connection that isn't bead rolled and it's fine after some hairspray and torque.

Go to napa, and get some constant tourqing hose clamps.

tbolt clamps > worm clamps

constant torque owns all

"Revolutionary clamp that reacts to changes in hose systems by actually increasing and decreasing its own diameter as the system expands or contracts."
