You have teh skills in Solidworks. :cool:

Thanks for sharing dude.

If I didnt already have the bits and pieces for my ps conversion sitting here Id look into this for sure.

For the record, Im using a 70series cruiser box, Surf pitman arm, and ford teardrop pump.

Out of interest do the pitmans suggested already have the correct taper at the tie rod end? I personally think making an adapter plate for the vit box would be easier than the new bolt pattern, crush tubes and hose work but I love the idea of having the steering line parrallel with the chassis. I overcame the the vit box angle with an additional uni in place of the rubber vibration joint.

i'm hoping the vit box isn't only bolted to this plate. all box bolts should go through the chassis and not just into the plate.look at the vitara and you will see it has shanked studs that go all the way through.

Yeah I understand where your coming from. The way the plate works 3 bolts run through the plate and chassis from the passenger side in the standard sierra location. This mounts the plate to the chassis. Then 3 bolts run back through the plate and box from the drivers side. This mounts the box to the plate. This effectively spreads the load across the same area of the chassis as the standard box. I dont see how this is any weaker as standard. Any force on the box would pull the bolts and crush tube through the 3mm chassis wall long before it pulled the bolts through the 10mm plate I would have thought.

Once again I'm not simply trying to defend the way I've done mine. I think your design is fantastic. I like hearing other poeple's points of view. That way if someone points out something inately wrong in what I've done I can improve/ change it. Especially if it saves me from rolling at 100km/h ;)

going by what gwagensteve said 11_evl has had this method approved by an engineer. I doubt they would approve somthing weaker than standard/something that would comprimise strenght & safety. They wont even approve cut,welded or modified steering links/arms. And the ones who will, would want to have them x-rayed.

Sorry, Its wasn't my intention to start a competition. I wanted you to point out where you feel the weakness is in the vitara box mount. That way if I feel its credible i can take action to try and make my personal set up better.

I have a Cressida power steering box in my zook, and its a pretty nice install.
Gwagensteve wrote:What makes the cressida box better than a vitara one? The mounting pattern is pretty much the same so the labour to fit doesn't really look any different.

Steve.
The Celica box mounts with the steering shaft parallel to the chassis, unlike the Vitara box where you either need a wedge or a uni joint. This means you just use a rag joint, just like stock.
The steering shaft also bolts straight up without having to cut / weld it to change the length. You just slot out the holes a little on the Toy rag joint. The box also clears the radiator mount and front guard.
Oh, and you can either use the Vitara pitman arm (which has the same taper as your stock drag link but little drop (good for hi-steer), or you can fit a Tarago arm, which has about the same drop as a stock zuk pitman arm, although then the taper is larger, so you need a different TRE.

What you need is an adaptor plate like this:

Thats what I made to fit mine. I have sold a couple to guys over here in NZ, and I know of one in a truck that has been certified (what you guys would call "engineered") with the conversion.

Price please Ben :) Does the plate move the box out enough to use the standard steering column and rag joint, or do you need an angled wedge?

Hey Ben,

That plates for the vit right? If so thats exactly what I've done. Just not as fancy with all those pretty curves. :) Shes just a plain old rectangle.

Bens plate is for a toyota

"I have a Cressida power steering box in my zook, and its a pretty nice install. "

It moves that box out about 10mm to line up wit the standard shaft . His is a copy of my plate I believe .Link to my old web site on the install .

Ah ok. I wasn't sure which box it was for. Is the cressida box a more powerful box than the vit one, as in turning force? Or is the force determined by the pump? I find my vit setup one a bit lacking at times but its intermittent making me think there might be an issue with my box.

The Cressida box seems powerfull enough. I'm using a Vitara pump. I have beadlocked simexs and a front lockright and don't have too many issues. Having said that I haven't driven vit p/s for any length of time, so couldn't really compare. If you believe the Rocky Road website the Toyota setup is stronger.

If you shim the pressure releif valve in the pump you should be able to up the pressure and get some more grunt out of your current setup

Yes, as above, you just use this plate and don't need a wedge. The stock steering shaft then bolts up without needing the length changing or any extra uni's etc.
I'll look into the price again - it's been a couple of years since I made some. I would need to make a few to make it worthwhile, so maybe PM me if you're interested.

Cressida box is geared strongly in my opinion as my mate had one not connected to his p/s pump and i compared to my vit box with no pump connnected and you can tell the difference in gearing. Only my experience.

M12 X100mm Gr 10.9 socket screw seems available. Should be stronger than a Gr8 bolt.
