Any idea when you'll have the boot extensions? I'm willing to wait for the complete kit, but just wanted an idea of the time frame.

Hi, Rick's wife here. Ricks been working 16 hour shifts so, he hasn't had much time to work on this. Hopefully, he will have the next couple days off to work on this project. He told me today that he is gonna have to take the boot extension plans to another machine shop as the guy that is suppose to do it just can't seem to get the time to get it done.

I hope that in the next couple days we will have a more concrete time frame and a shop ready to work on this.

Thanks,

Jen

Thanks for the update. Again, I'm in no rush. I know how life has to come first.
Just wondering if he had a time frame. Tell him I said thanks for all the work he's done on this. I look forward to the setup when they're ready.

OK, the shop has some of the boot extensions that are just about ready. A farmer dragged in some broken harvester that needed emergency repair. So I will grab the parts he has and try to ship 5 or 6 sets tomorrow? He makes VERRY little money on stuff that I bring him, but the farmers are his bred and butter so they are first in line every time. Even if his is actually working on my stuff.

THANK YOU very much for being so patient.

Sweet. Now I have to go get a rack.

It's and 84-96 rack correct? I may just have to reread the whole thread.

I don't have a 96 rack, but I know there was some type of changes between 84 and 96. So, your best bet is to get an earlier rack 84-91. I would like to get my hands on a 96 rack just to see if there are any changes.

I could not get the parts out of the shop early enough and box and ship before I have to leave to San Diego for 3 days. He is still working on the farmers equipment.


If you don't want the boot extensions holding you back, I can still send the adapters without the boot extension anytime. Or if anyone is concerned that I am trying to scam them, send me a pm and I'll send your money back. I know this is taking a long time and could seen suspicious, though that is not what I am doing in any way. I should have just taken the blue prints to another shop a month ago, but he does so much free work for me it is hard to say give me my stuff back I am going somewhere else. Sorry, for yet another delay.

Hi all,

Sent out another set today and I will be dropping off the rest tomorrow at the post office. Rick still can't get any more boot extensions, so we are sending out the adapters and brackets now. Not all the Corvette racks need the extension, so if you end up getting one that needs it you can let Rick know and he will get one out to you. Still trying to get a few made. This has gone on long enough and everyone has been patient. Thanks so much.

Jen

Awsome thread! with great info. i have read through the whole thing, and missed what i was looking for - a test drive evaluation.?
you have been on the road with it? (obviously if you are making sets . . .)
how does it drive? what is the feel like?
cool stuff

Thank you Rickady88GT. The adapters and mount look very well made. Now all I need is to figure out where I can duct tape a power steering pump on the 2.8...any ideas?

I just saw an add in KitCar magazine for an electric power steering "pump" that attaches between the end of the steering column and either a manual box or a manual rack. It looks like a great idea for our fiero's.....it supposedly is adjustable also.

Powersteering is nice, and an electric pump might be an easy way to do it. But the real treat with Rick's upgrades is that you get a faster steering ratio. You won't get that with a slap-on electric pump.

Just a bump to keep this out of the archives.
Has anyone installed theirs yet? Hoping for some real driving impressions.

I havent found the time to weld mine in, when I do I'll post results here. Also is there an electic pump that attaches to the lines of the rack (not the steering column)? I Have am l76 with powersteering pump that I was going to use, however it looks like I will not be able to use it in the fiero as the alternator needs to be moved down for decklidclearance and dogbone mounting into the area the PS pump is in. I could move the alt to where the AC is but I would loose AC... Anyone else run into this same problem??

I may start a sepperate thread on this but just wanted to bump this excellent one first

I understand your problems, unfortunately I have no concrete solutions. I am going to pursue installing the MR2 electric power steering pump. The problems with it are that it either runs full blast all the time, or you need to control it somehow. To control it you can transplant the entire system from an MR2 (expensive and hard to find all the parts even in the US) or come up with your own circuit to control it. I still haven't worked out the electronics, but I have some friends who can help me with it.

As far as the L67, I have heard of similar problems, but you are ahead of me on the engine swap.

Rick, do you still have any adaptor sets? I have had a ZR1 rack for some time now, but am still completing a Nothstar install. The rack is next on the list.
Thanks, Dave.

Yes I have some left. I just need to make more mounts for the adapters. If you do the N* swap you can use the pump that is on it. Just run the lines to the rack.

HaHa. I would never have a manual steering Fiero again, 88 or not. The faster ratio is the selling point if you want less effort or not.

Is this the date stamp showing this ZR1 rack is of the date 08/11/86?

It also has the number 7849001 cast into the input shaft neck, is 2 turns full rotation, and has about 4.25" stroke.
I got it as a freebe at the local yard for giving one of the owners some parts off my doner Caddi Deville.

will this work on 84 thru 87's or will your mounts only work on 88's?

has anyone tried driving it without it hooked up to power steering with the corvette rack? I may just have to beef up my arms a little.

It could control the current to the pump so it gave none (or very little) at speed and full power under say 5 mph. I think its possible, but I am more mechanical than electronic, so I am probably not the one to test it out.

Edit: Question: Would the pump wear out to quickly if it ran all the time the car was at less than 5 mph? Does it then need a mechanism to turn on when you start turning?



Ahh! I was hoping I could be of some assistance in this project... here's where I come in.

There aren't any widespread speed-triggered modules out there, but there are alot of RPM triggered modules, like the ones MSD makes. Could mod one, as the signal put out by the sender is a bunch of pulses, just like a crank sensor.

Another thing too, the sender unit is a small permanent magnet generator. Could just make a circuit to sense how much voltage is coming out of it, and have that flip a relay off.

My meter has datalogging capability. My Fiero is in the middle of an engine swap right now, but when I get it back up and running, I'll patch my meter into the signal coming out of the speed sender and see what is put out at what speeds.

I've done circuit designing before, so this is an easy one for me.

As far as preventing the pump from wearing out at idle, I guess something could be rigged into the circuit to sense when the brakes are on. Maybe have it turn off when the brakes are on for more than 20 seconds and the car is at 0 MPH.

I have come to this party late, but it seems that this thread has stopped abruptly. Has anyone finished with their vette rack install? How does it handle? I know it is a long shot, but Rick, do you have any more of those brackets and adapters left?

I have something to contribute. I don't know if any of you have seen this before but have a look...
http://www.fierofocus.com/a...Power%20Steering.htm

It was sold through Saturn dealerships. Maybe you could buy parts?
Now if we can only find the rack they used on the fiero!?

The 2008 Saturn Astra (coming out later this year) will have electric power steering also.

Hmm... some good thought in there I hadn't thought of. If you get to working on this, send me a PM or email, I'd like to talk about how to implement this kind of thing. Circuits are not really my thing, but the brake pedal timer thing sounds good, except that with my manual transmission, a lot of times I don't keep my foot on the brake. Maybe instead a timer on the RPM signal; when the RPM's stay below 1000 for over 5 seconds, idle the pump. How's that sound?

I would think that trolling around a parking lot in an automatic, or actually parking, you wouldn't always take the revs up past idle. I know that when I do parking lot maneuvers in an auto I usually have my foot on the brake rather than the gas.

Bad news. I finally got around to looking at my supposedly 1993 corvette rack. I took off the corvette inner tie rods and was aghast to find...female threads? Hmmm, either I got hosed on ebay or one of the changes to the rack was to invert the threads. Unfortunately, both are possible scenarios, and since its been over a year since I bought the rack, I really have no way to complain or say anything. Hopefully I can still use it as a core at Autozone or something.

Good luck to everyone else with their projects.

Something to keep in mind is that the clutch has a switch too. The Fiero has a ignition kill switch on the clutch pedal so you can't start the car without the clutch pedal being pushed in. Could just tap into that.

Sorry to hear the bad news about the rack.

I hope this concept becomes easily feasable. I really could use a new rack on my 88.

Yes, I had thought of that, but many times in a parking lot situation, where you need significant power assist, I would have already pushed in the clutch and be coasting as I turn into my spot. On the other hand, as I leave the parking lot, I sometimes have the clutch fully released in first gear as I make turns through the lot.

So, I'm still looking for an electronic solution. For now I think I am going to keep the wires for the MR2 steering position sensor, but not use them and leave it run all the time. There are some EV (electric Vehicle) people who have done the same (leave it run) although I think they put in a manual switch to turn it off to save battery power. I think the pump should have a very high duty cycle rating, so we'll see if I burn one up.

Thanks for your concern; the rack will turn out ok. I'll get a rebuilt one and use the old one as a core - still get more than I paid out of it. I am pursuing this because I too could use a new rack for my 88. It has sloppiness in the middle. If I tighten it down, then it is too tight at the ends. When I leave it loose at the ends, it is very sloppy in the middle.

My issue is, I can't tighten it down. The ring around my adjustment screw is stuck. Even tried Rodney's tool.

If it is significantly loose in the middle, you might end up with my problem if you could tighten it down. While I haven't tried it in the car, The corvette rack I have (wrong one for this conversion) is relatively easy to turn (similar to my tightened Fiero rack) without the power lines hooked up. If you are eventually going to do this conversion, you may want to think about getting a used rack, draining the fluid, and attempting to use it as a manual rack until you can get the hydraulics worked out. Just a thought, anyways.
