epas, electric power steering
Discussion
Im over the moon with my newly fitted power steering,works an absolute treet,its the epas unit from cosa with a seperate knob for adjustment of sensitivity,my p&j is now even better with pas,i had previously told everyone it did not need it,but now its on what an improvement,ill take some pics if anyones intrested in going down same route.total cost £90 for bits.
pics as promised sorry for quality its hard lying camera on floor then pot luck as to what comes out.control knob for adjusting sensitivity 
bracket made from 2mm plate bolted to pedal box.
control box bought off ebay £38
the column was £40 from corsa b in scrap yard.@£10 spent on wiring/40a fuse holder.
remove column measure its length,make sure its the same length when youve put the corsa bit in the middle of it,i didnt keep any of the measurements so just be careful,its still a collapsable column using the bit off the corsa welded to tvr top part of column.i left corsa uj in afterepas bit and welded that to the bottom part of tvr column.i made a "L" ish shaped bracket to go full width of pedal boxand bolted epas unit to that.
the wiring was simple enough using corsa ecu you need 6mm cable for + and - from battery with 40amp fuse goes to ecu,i bought the control box off ebay which just needs an ignition live and small earth thats it without writing war and peace.i would have preffered to have it speed sensitive but it works drives just fine.anyway any questions just ask.

hi safety wise the column will collapse the same as it would in a corsa,its as good as origional column/better,if you take youre origional column off and see how its been lengthened youd know what i mean.
Please give me a link to any corsa eps about cracked bulk heads as i would love to read it.
so long as bracket is good and strong there should be no twisting by the column itself,its on a worm drive.The motor turns the worm,turns column.the motor is at 90 degrees to column motor turns one way,column the other.
Im crap at explaining myself but do you really think id drive an unsafe car,knowing i caused it.
please dont anyone do this mod unless they are very mechanical/very good welders.

hi spinbo
dismantle corsa column top part remove 3 bolts holding it to epas unit,the corsa shaft joins the epas unit via a collapsable spline drill the nylon pins out from spline and tap off outer spline piece,this is the bit to cut and weld to the tvr column so it taps/slides back into place and can collapse if all goes wrong,the outer consertina part welds to tvr column and bolts back on to epas unit,for belt and braces aproach see second pic just above concertina bit i drilled 6mm hole so i could see splines were properly together.also doing it this way means no heat during welding goes into epas unit.
the bottom part i kept corsa uj again so as no heat from welding goeas to epas unit,where corsa nuckle joint is conected knock out the centre part,its round with two fats,same is found on the tvr column knock this back in and weld,just make sure measure twice cut weld once.
On the subject of torque and bracketry peter is right the pedal box is best place for it,+the motor only turns the inside bit of column,nothing is trying to turn the outside of column.
As for it showing only if you put youre head down to look for it,while driving it cant be seen,or felt by my feet(size 10s)or my knees.
Hope this helps nfb.
