Just did a 3.1 4t60e swap for a friend. The engine still has the power streeing pump on it....... so I figure why not just run some steel lines to the front and have power steering.
The only problem is that I have to find a suitable power steering rack + pinion that can fit on the fiero.
Anyone know what might fit???

Rickady88GT put a SS Camaro rack in his 88GT, and then wondered if a WS6 Trans Am rack would fit also so there was one installed into my 88GT.
Low and behold - they DO!
Final result: While there are those that complain and state that there is no need for power steering, that 2.25 lock to lock is flat out something else. PS is nice being that I have 17x8's w/ a 35mm offset on the front end as well. Single hand turning of a Fiero in a parking lot and while parallel parking - who'd a thunk it?

I used a 97 Z28 camaro rack for my 88 GT, it's quite an easy swap, i got it all done in one evening. It works really well, you lose a little bit of turning radius on an 88 but it will have a slightly tighter turning radius on an 87. The quick ratio is really nice especially for all the slalom racing i do.

iv been kinna curiuos about if there was a steering rack that had quicker ratio turning than the fiero (ex 2 turns to fully turn the wheels instead of 3). is this the only one, or was there some other one? maby one without PS? i heard about this way back when i was first getting into fieros, and have been curious since, i figure this is a good post to ask.
sorry to hijack, but i am just kinna curious about this. thanks!

the performance f body steering rack, (the one i used) is 2.25 turns lock to lock as opposed to my original 88 rack which was 3.5 turns. i'm not aware of any faster manual racks but an option to look at if you want to keep it manual would be a steering quickener. they're designed for dirt track racing i believe. i think you can get them in 1.5 and 2:1 ratios

Originally posted by Raydar: Allen, I know people were asking about a kit in the other thread. Is Rick even considering that?
I dont think so TBH. There is quite a bit of work that needs to be done to the front end of the car which would require the front cradel to be at the house for fabrication.
I know that with both of the installs that Rick has done, there is no loss of steering radius at all. Adapters were used & made by the local machine shop that allowed for the stock turning raidus. Otherwise yes, you are going to loose alot of the turning due to the fact that the tierods are longer on the F rack that the P rack.
Rick really would be the one to answer this - as Im not **positive** about specifics.

You just cant get a faster ratio steering rack and stay manual. A car driven on a daily basis will NEED power steering if you want faster ratio. The wheels will be to hard to turn at very slow speed for a daily driver. Fighting that steering wheel SUX.
OR you can modify the steering arms on the stock Fiero knuckles like I did. This will give you a faster ratio with out even touching the rack.
Steering ratio is determined by the Rack AND the steering knuckle/arm length. As has been said the stock 88 rack is just over 3 turns lock to lock (closer to 3.5 turns lock to lock) and the LS1 "F" Body racks are 2.25 turns lock to lock (and this can be changed too). The inner tie rod hits the body of the rack as the steering stop, just like the stock 88 Fiero rack. But the "F" body power steering rack has a shorter rack gear inside the rack by about an inch. So the Fiero will loose some turning radius by only putting in the "F" body rack. I had a machine shop fill and re drill a set of knuckles so the steering arms would be shorter than stock. This made up for the less rack travel. BUT now my tires rub before full steering lock. As is I cant turn the steering wheel to full lock or it will rub. So the modified knuckles are not needed. I drove the Fiero with and with out the modified steering arms and I prefer the stock Fiero knuckles. BUT I have wide tires up front with WCF 12" Corvette Brakes that relocate the Brake caliper up and out a bit. So I don't know how the modified knuckles will work on a Stock Fiero. The steering ratio with the modified knuckles is even faster than just the Fast Ratio "F" Body power steering rack. I LOVE the fast ratio power steering in my 88 Fiero and will NEVER go back to manual steering again. ALL my Fiero's from now on will be power steering.

Is the Chevette rack+pinion an easier alternative (I know it doesn't have a a low lock to lock ratio)........ but for an idiot like me....shouldn't it be an easier swap?
(after all the fiero did get its front suspension from the chevette design)

The critical dimension for a substitute rack is the distance between the inner tie rod ends. Both the F-body racks and the Chevette rack will require extensions to be fabricated so that the inner tie rod ends will be moved out to their proper position. Without these extensions you'll totally screw up the geometry of the front end. Measure the length (width??) of the stock rack without the tie rods. As long as the new rack has that same dimension your steering geometry will be unchanged!
