I'm buying a power steering rack for my smf ef and want to see if I should add a steering quickener.

Wikipedia lists 4 turns lock to lock for earlier ef ps racks, but the 91 ex supposedly is 3.1 turns lock to lock.
However I'm not sure I trust their info.

Does anybody here have a 91ex?
Can you confirm the number of turns lock to lock?

If it really is only ~3, I might not have to add a quickener.

 

NOBODY has an ex?

 

the STD/DX/HF rack has 18.6:1 ratio. the variable Si rack has 19.8(18-20.4):1.

i think that means its nominally 19.8:1 but varies from (18-20.4):1

turn lock to lock is listed 3.8 DX and 4.1 Si.

also the power rack ratio is 17.7:1 with 3.65 lock to lock.

taken from the civic factory helms. not found online, i have a physical print.

 

I know this is majorly back from the dead, but did you ever find the answer to this? Asking for the exact same reason.

 

It's 3.65 vs 3.8 or 4.1.

It's not 3.
