I thought removing all hard lines might have been the reason.
There is a decent amount of room under there if you don't want a lot of the air conditioning and air vent stuff. I've saved heaps of room ditching the heater unit for a smaller unit

Ill be keeping the stock heater unit, but yeah, the crotch vent pipe will probably go.

If i cant fit it in with the motor pointing up, it'll end up being like this which will still be ok...

hmm.. reservoir looks like it sits below the dash trim line. Potential leg interference or are you good?

Reservoir? You mean the electric motor.
That not my car... thats a photo of someone else who has done it in a Corolla.

It might hang a little below the dash trim like that, but i dont think it would get in the way of your legs/feet.

I think the ZRE152 EPS motor isn't as long as that one either.

Yes, your signature says and I have read through your project before. Hence the confusion with the LHD older vehicle.
So when do expect to have everything completed?

Ahhh right :twisted:
Yeah, those photos are from a guy in the US who has put the Yaris EPS unit into his AE95.
Work log is here: http://www.toymods.org.au/forums/engine ... ering.html

I have no idea when it'll all be done.
Even though im manualizing my steering rack now, i might not have the EPS unit installed under the dash for some time. If i need to drive the car before i get the EPS unit installed, it just wont have any power assisted steering.
A friend of mine is currently stripping down a ZRE152 for rally use, so probably wont be using the EPS column it has. Ill wait until he is happy to hand it over.

So here is my documentation of the same conversion on my 165. I ran an 08 Scion XD column and used an ABS computer, just wired it up.

Nice :)
So is your blog up to date? Its still running in limp-home mode so far?
Megasquirt can't output CAN bus packets suitable to run the EPS without specific support being added to the MS firmware.

Its been a while since i update this thread... mine is all up and running & on the road.

Test fit:
