Power steering questions

[black89targa]

So my project is an 87 Supra sport edition. As far as I know, the n/a supras that were sport edition came with PPS. also I plan to swap a 1jzgte in this body (the 87). I want to run without P/S and A/C

from searching I found out "the pre89 power steering racks have a power steering damper that looks like a shock absorber (it IS actually) and IIRC it's mounted to the front of the rack."

Here's my questions.

Can I just fill the rack with fluid, and cap it off? If so where do I fill and cap it off? Will it damage the rack because factory is had the damper and PPS?

Also

What belt will I use if I dont want a/c or p/s in the 1jz? I know what belt to use if I just don't want a/c, or just p/s, but what if I don't want either of them?

Thanks!

If anyone could help that would be amazing!

no, you cannot fill the rack and cap it, you would have to install a bypass between the high and low pressure lines on the rack, or else the fluid will be working against you as you turn the wheel.

3200+ lbs of car vs 200 lbs of human with the torque arm advantage on the cars side = a the human losing the physics battle.

You need either mechanical advantage by gear reduction or hydraulic assist.

Actually the car weighs 4,600lbs. which isn't better thats for sure.

I ask because i have no idea on power steering lines and how to make them work with the 1jz.

I'll search thanks guys!

Custom lines from a hydraulic shop would be one way but I'm sure some of the guys that have swapped Jz's in have a solution.

4600 is the weight with people included
(Mine weighs 4020 wet and has to one of the fattest I know of)

Did you put a mack truck on top of the supra when you weighed it?

:naughty:

4460 on the door jam. I have a cell phone pic but its HORRIBLE quality.


Thanks IJ for the help!!

Yep the 4460 is total weight including any passengers

I fail. at least i know my car isn't a fattie :evil2:

Thanks again IJ

Mine is

My 87 n/a(sport as well) weighs exactly 3400 lbs. Weighed it on a CAT scale.

I think the pps only comes on the 89+ models(I don't have it).

With PPS

WIthout PPS

The PPS has the electronic control valve, while the non-PPS doesn't.

My Bud's 87t has PPS.

My Bud's 87t has PPS.

You live in a strange place =P (I was actually born in Australia! Don't remember it at all though...)

In the U.S. at least I'm 99% sure 89+ turbos have PPS. Everything before 89 didn't have it and I'm not too sure if any 89+ N/As had it =\

 

[black89targa]

So if it's not PPS can I do anything to go without P/S?

It doesn't feel very hard to turn the wheel, and my 89 doesnt have p/s.

Here's a pic and you might be able to tell if its pps or not.

Thanks and sorry for the POS camera quality.

Get us a pic of the rack where the steering knuckle joins it.

EDIT : Holy moly I need to make these thumbnails.

FOUND MY USB CABLE!!

LHD Racks look very different Nathan, I'm NOT seeing any PPS there though!
(usually a small solenoid and wires)

leave the power steering on. i just put mine back on after not having it for a year? maybe less... and i'll never put myself thru that again.

even though its on the lighter side, 86.5 sport model, with a bunch of crap gone and e-fans... i could turn the wheel pretty easy without p/s. but with p/s, good god its so easy! but i lost most of my 'road feel' that i had.

if you want to elimiinate the pump, get a spare fitting that goes onto the rack, and then run a feed line to the rack via the overflow, and then just cap the big nipple/old feed for the pump, i had it that way and had no problems. just need space for the fluid to go when you go from full lock to the middle.

Thats not a PPS rack.
