Rack and pinion question?

[mercuryfreak200]

I have a rack and pinion (steering rack) from an 89 N/A supra mine is an 88 turbo will the rack fit mine? I gonna change it out today since its soooo nice outside and will be even better the next 4 days. Do I need to change the hoses out I got all the hoses from the N/A parts car and the resivouir too. thanks

my interchange books say no. 86-88 fit and 89-92 fit. now it does give me 3 options for the 89+ racks, as turbo, non turbo with PPS, and non turbo, w/o PPS. but none for the 88 under.

it might fit, but you wiould have to compare the 2 side by side. difference could be the steering gear ratio, which is enough for my interchange books to say its not the same.

Ok I looked online a bit and it doesnot have the electronic assit on it don't know if that makes a differance. What would be the out come if the gear ratio was off turn too wide or not enough? Maybe harder to turn?

Also I measured the mounting pionts for the fram they are the same. The hoses are bent a little differant though.

the gear ratio will affect the wheel in the car, like if for say the old rack was 2:1 gear ration (2 turns of the wheel from lock to lock) a box with say 2.2:1 will mean you spin the wheel a little more.

lines arnt a big issue, as they can be rebent (though very carefully) to fit. perhaps the old lines will fit the rack? but why you replacing the rack? is it leaking?

As long as both do not have PPS, they'll swap just fine.

It leaks all over the place. Out the boots the line fittings, It even squirts the hot side of the turbo when its at full lock in both directions lol. Smoked me and my buddy out of the car. I thought it was on fire so it kinda scared me, partly why I don't drive it too much, don't want a firey death to me or the car lol.
What is pps and how can I tell? Neither have any electronic connectins on them.

PPS - progessive power steering. it will have a solenoid somewhere on the lines from the 89 car.

 

[mercuryfreak200]

No theres no solenoid on it that I can see.

The only thing that might be an issue is the pulley sizes changed on the pump as well over the years.

Didn't think of that. But I may be able to get it from the guy I bought it from.

Also the guy I bought the car from is a toyota master mechanic and just retired a couple years ago. I just called him he said that it shouldn't make a differance about the pulley side but if it does he said he would give me the whole pump and bracket as well.
