This way is free to do if you have the right tools. I'd reccomend doing it this way rather than just looping the lines.

It's not advisable to just take the belt off or something like that if that's what you mean by disconnecting it. You will be putting the entire steering system under more stress, and you'll have hugely increased steering effort to the point of it being potentially dangerous in an emergency situation. You need to at least loop the lines, or drain the rack and plug the holes.

There's no negative side effects to doing it properly, other than some increased steering effort at low speeds. Once rolling I can still steer with a single finger if I was so inclined to do so (keep both hands on the wheel at all times). I've never regretted doing that mod.

So what is beter - putting a manual rack, or doing this mod to the 15.2 rack?
I have a manual rack sitting in the garage, so I was just wondering what is better to be done?

"Better" is very subjective. A depowered 15.2:1 power rack will keep the same fast steering that you're used to, but will come at a cost of increased effort. A 20:1 manual rack will require less effort, but the steering will be slower.

It's up to you which one's better. I'd suggest that for now, since you have a manual rack, then swap that in, and see if you like it. That way you can always go back to power steering, or convert the power rack to get faster steering. It'll give you options before you permanently modify the power rack.

hey stole this from the link you provided, thought that it answered the question


"This mod is for anyone who wants the improved steering feel of a manual rack without the slowness of the factory manual rack. It also gives you the benefit of never getting ahead of the power steering during hard driving (autocross). As an additional benefit, this will get rid of a fair bit of weight off the front left corner of the car and free up a lot of space in the engine compartment if you don’t have air conditioning (the a/c bracket bolts to the p/s bracket I think). Finally, in my view, the absolute best part of this is that it’ll help you improve on the weakest part of your car’s performance, the driver. For reference, the manual racks are all 20:1 whereas the power racks were available in a 17.4:1 and a 15.2:1 ratio. I WOULD NOT RECOMMEND THIS FOR THE 15.2:1 RATIO RACK. The steering effort would be too high to be liveable on the street. The 17.4:1 rack, which I have, will be perfectly liveable on the street though.

The cars that got the 17.4:1 ratio racks are as follows:
The 89-90 GTUs, 90-91 Infini, 91 Coupe, 90 GXL, 90 GTU, and the 90-91 Vert.

The cars that got the 15.2:1 ratio racks are as follows:
The 86-89 GXL, 86-87 Sport, 88-89 GTU, 86-87.5 Base, 87.5-88 SE, 86-87.5 Luxury, 87-91 US spec Turbo, and the 88-89 Vert that were equipped with power steering"

lol no need to. This Info can be found In the 2nd Gen Archives that Black91n/a posted.

Since posting about not reccomending the 15.2:1 rack for manual conversions I've hard from a number of people running them without power with no complaints, but I've also read people complaining about them when they run wide or sticky tires.

I auto-x my 15.2 with the PS removed and it's just fine. It's just harder to parallel park. But my car is strictly a race car.
