Power steering pump, Toyota

Can a Miata power steering rack fit easily on a Pantera?

Ken,

I realize you like to go your own way and find solutions, but an EPAS power steering is so much easier and unobtrusive.

This was not hard to do and the Miata power rack is proven

How does the Miata rack compare to the OEM Pantera rack, dimensionally?

Which Miata is this? year, model?

Hi Ken,

Would love to see a detailed explanation of what you did and why, including part numbers of the components used, so someone else doesn't have to reinvent the wheel.

Cheers!

I wonder if it could be configured in the area below the front trunk (with a weather shield) above the steering rack…. Where dropped battery trays have been located?

Put a couple (4) round head bolts through the trunk, and hang it upside down.  The reservoir could still be accessible above, with longer hoses.

Does it make noise?

Had to fab new mounts for the rack, not for the novice, it’s not a bolt in.

tie rods need to be shortened.  I forget what year rack I used.

got it from the salvage yard.

i also modified the upper control arm for more caster.
the mr2 pump has an adjustment on it to control the assist to the feel you want.

You can’t hear it when the fans are running

If you had to shorten the tie rods, I assume the Miata rack is longer than the OEM Pantera rack.  Did you check with anyone knowledgeable about suspensions and steering geometry before deciding to use a longer than stock steering rack?

If the articulation point of the tie rods is no longer located in the plane of the arm joints, induced steering movements are necessarily created during suspension movements.

Many years ago, Gary Walker ("comp2" in these forums) went to great lengths to eliminate bump steer, which he felt was excessive and caused, in large part, by the OEM rack being too long. He also converted to hydraulic power steering but modified the power rack so it was shorter than the OEM rack.

Thanks for the info
