Hey,

I'm running into some trouble with my IC piping.So what I'm thinking about doing is getting one of DJButton's high pressure lines.

Then running one of these universal coolers for the other line on the rack.(the other line that screw's into the rack and goes across the xmember, then back to the reservior)http://store.summitracing.com/...w=sku

The reason for all of this is my turbo.I'm running one of those SSautocrap stock style exhaust mani's and a T3/T04E turbo, with a internal gate that I can get only to fit clocked one way.Which is with the Discharge straight down.Also if you look there is a hose that goes from the reservior to the PS pump.It's been ghetto rigged just to get the car started. What is everyone else using for that?Because the size of the pump is bigger than the size on the reservior.

The Problem

Here's my IC piping that I'm gonna be working with.You see the Hotside where it comes up, then makes a vertical 90* left then another horizontial 90* right towards the firewall.Well that pipe needs to be cut up and fixed.

I was thinking that when it comes up out of the fender and makes that vertical 90*, to continue it to a full 180* (short radius) and then make a 90 * towards the turbo.On the turbo I'm going to have a 90* coupler on there facing towards the radiator.

But the High pressure line is in the way of the IC piping.And the low pressure (i think) line is in the way of the turbo. (where the 90* coupler will be going.

Now the problem I'm having is if I get the univeral 3/8" barbed end cooler, how will I connect it to the rack, and then again to the reservior.Which the rubber line on the reservior from the stock PS cooler is roughly 10mm or .40"If I got the universal cooler, I'm sure I could squeeze the 3/8" (.375) line onto the reservior.

Is anyone running a aftermarket PS cooler on their car??If so can you post up your setup?

Thanks

personally I'd try to run a 90 degree elbow off of that and weld it straight onto the compressor housing. Its hard to tell how much room you actually have in there but it looks like their might be enough.

You can always bend the hard lines down that go over the cross member so that the PS lines have some more room between the housing. Of course your going to need to modify your hot side piping as well in order to make it work.

As far as power steering coolers are concerned 240's don't need them since our front ends are so damn light the power is plenty powerful enough w/o having to worry about heating the fluid to much. I know supra guys run them, but they got 800-900 lbs on us.

I'll post a picture of the oil cooler that I went with, I got it from fleabay for around $15 new. I believe it was from a Jeep or Dodge van. It is a basic double-pass finned piece. I like it, and it works well.

On thing I did notice in your 2nd pic. get that heater hose out of there ASAP! Get some standard Power Steering hose. AutoZone has it for under a dollar per foot. Don't ask me why I am so paranoid about this..

I have a PS cooler because I planned on _driving_ my car, and I used the R33 X-member / mounts.

I'm changing my PS line for two reasons:

1) I hate the god damned S14 PS line getting in the way of the radiator and everything else because it is looped. I was so happy to see it go.

2) Big black rubber hose looks hideous compared to braided SS.

I just ran a dash 6 PS line to the rack and hopefully the fittings I have won't have to be "modified" much. On the low pressure side, I am running a small Perma-cool unit that was like $20 and has 3/8" barbed ends on the same side. I am mounting it on the frame rail underneath the car where it angles upwards so it gets good air flow and is away from engine heat. I'm sure if I hit a racoon or something, it would rip it off, but that is just a chance I'll have to take. Not planning the build around hitting stuff.

As far as your intercooler piping, you can't clock your compressor 90 degrees and relocate the PS reservoir? If not, it sounds like you are stuck with the piping setup that you described.

And yes, NICE NAILS!!

I was thinking about that, but since i have that SSautocrap mani. The manifold may change so I dont want to permanently weld anything to the turbo.

The reason I was going to put a ps cooler in was because I was gonna take the stock one out. Actually I could pull them off the car and try and bend them out of the way.Because there is space to the right of the turbo.

Yeah I gotta get rid of that heater hose.It's seeping through the hose.What hose are you running?The RB pump has a large Dia than the reservior.

Darius, I read somewhere while I was searching that you can't use SS lines for the High pressure because they are not made to run at such pressures. Some guy from SPLparts posted it.DJ button has a line that would clean up, but its still black rubber.

What size and thread is the fitting on the rack???

Yeah I originally tried to clock the turbo at 1-2 o'clock and the wastegate actuator was not lining up.

Thanks guys,I spent all afternoon polishing my nails while watching Oprah.

actually if you got their top mount manifold, or any top mount manifold for that matter it will fix your clocking issue and point the compressor at the shock tower... soo do consider that.

we have a stock PS unit? I don't remember ever ****ing with one unless its attached to the rack?

also what made you choose pink btw?

Sil240,

You are correct about the braided SS lines. They are designed to be low-pressure PS lines at most. Not meant for high-pressure hydraulics. You can always get an 'engine dress-up' kit and put it on that way..

I'm running either 3/8" or 5/8" (can't remember.. if it were metric I would.. *rolls eyes*) I will verify / edit when I get home tonight.

I _think_ I am running 5/8" between the reservoir-out and pump-in, and 3/8" for the rest. I have a pic I can modify @ home if you have any questions.

I really don't understand why you can't reclock your turbo. Is there something in the way I can't see?

Your hands are very feminine.

Evan

BTW, the only thing that looks worse then black rubber hose is dirty ss braided lines. LOL

Yeah I know, I really don't want change manifolds till I get a good one or this one cracks. (hopefully it wont)

Yeah the stock power steering cooler is the aluminum line that goes from the rack across the x-member and back to the reservoir.

Right now I can't clock it towards the strut tower unless I cut a hole in it. I wont be able to attach or even get IC piping to it.

Lonestar- That'd be awesome.I def need some help with that.That line's been leaking ever since I put it on.Just to get my car moving around though.

The reason why I can't reclock the turbo is because I have a Internal Wastegate and the actuator will not line up any other way.The strut tower is in the way and the only other semi-possible way is clocking it at like 12:30 and the discharge touches the manifold.Which would be heating up my ic piping and also burn through the coupler.But.... if I did weld a aluminum 90* onto it then that would work out pretty nicely.Except for the fact the the turbo discharge would be getting heated up by the manifold.

That's my gf holding the pipes for me.I'm taking the picture. lol

I'm using Russell Powerflex PS hose rated for 2500psi. It is basically Teflon wrapped in SS braid. I used an M16x1.5 to -6AN adapter (steel) and then used Russell PS fittings for the high pressure line. Have you seen integra7's writeup on racebread.com?

Check out the PS hose I'm using too:http://www.russellperformance....shtml

No actually you ARE right. Regular SS is definitely not rated for the high pressures associated with PS or other hydraulics. That's why I'm using that for the low pressure side with the cooler etc.

While we're on the topic of power steering, I have a question about reservoir placement. I have to move mine away from the turbo since it is right next to the exhaust side.

How high does the reservoir have to set? Does it just have to gravity feed back to the inlet of the pump?

mine is moved next to the radiator and about the height at which the hood can still close. i think it needs to be higher than the inlet of the pump

If I remember correctly I had to bend the bracket a little bit, then just used self tapping screws and locked it down to the rad support, pulled the lines over and everything it basically fit no problem.

My turbo would look like this if I clocked it all the way up.[IMG]http://www.racebread.com/old/images/pow ... ed.jpg[IMG]

Thats a good thread but it's cheaper and easier for me to get one thats made already.

Yeah I gotta keep my feet looking good. lol

Gawdzilla's right it has to be a bit higher than the intake of the pump. So the pump does not get any air.

I think I'm going to try to clock it up at 1 and see if the wastegate actuator will line up.Then maybe get one of those aluminum 90* to line up with the stock piping.(Stock rb25 piping)

He He I make coolers like that at work all the time for local people who drift. I have to go to our 3/8 department to make them. Im working in 5/8 now. We just about have the heating and air contract for the freadom towers. Thats 300+ more units to this years contract.

It is up there a ways so I think it'll be out of the way of most debris. If not, the thing only cost me $20 so who cares if it gets hit?

Hehe, its not the $20 bucks that matters. I hate cleaning up messes!

Looks like it will be fine unless your tire kicks up something huge (then you likely have more serious problems).

I finally put my PS cooler in.I Got it from Summit $25 Deralle 1320.Then went to a local PS rack shop and the guy hooked me up with a nipple fitting that screws into the rack. The cooler came with a PS rubber hose and clamps and those push through rad zip ties.So I just mounted it vertically to my rad next to my 14" pusher.

Still fighting with my reservouir though.

I'll post up some pics later.

where did you get the ss power steering high pressure line and fittings? and could i get the same thing and run it from the pump directly to the rack and do away with the factory high pressure line as mine has holes?

Darius has the SS lines.

I got the line from DJbutton.Look in the Fabricators section.

You can run that line direct from the Pump to the rack. The cooler You can run direct from the rack to the cooler then back to the reservoir.
