For everyone out there who has been waiting for the 3.2 LTL Quaife steering quickener equivalent for their EK… I’ve solved your problem.
You see, the Integra and Civic rack are essentially the same when it comes to the actual rack teeth.
I was initially going to swap over the P/S Integra rack’s rack and pinion gears over to the Manual EK rack. This didn’t work for a few reasons, mainly because the P/S pinion doesn’t fit the manual rack.
The lessons learned there was that the manual EK rack and the P/S Integra rack had the SAME amount of teeth on the rack itself, and the ONLY real difference internally was the amount of teeth on the pinion gear itself. That’s the gear that goes into the steering rack from the top.
THIS is also the reason why the P/S EK rack has a slightly better ratio than the Manual rack.
So we have the EK manual rack, the EK P/S rack and the Integra P/S rack, with EXACTLY the same rack gears (in terms of teeth) and different number of pinion gear teeth.
Integra PS rack on top and EK Manual rack on bottom:
Civic manual rack pinion teeth = 7, with 4 Lock to Lock turns.
Civic P/S rack pinion teeth = 8, with 3.6 Lock to Lock turns.
Integra P/S rack pinion teeth = 9, with 3.2 Lock to Lock turns.
Left to right pinion gears - EK Manual, EK PS, Integra PS (I know the Integra looks smaller than the EK one, at the bearing, but it's not, it's the same):
The hook? The pinion assemblies from the Integra P/S rack and EK P/S rack are INTERCHANGABLE!!!
Here they are (Integra on top, EK at the bottom):
So… what to do, what to do…Well, I got a used EK P/S rack from the junkyard for $65, and a used Integra P/S rack for $70 pulled for me, swapped over the pinion gear to the EK P/S rack (or the whole pinion gear assembly, they are IDENTICAL), looped the lines and… 3LTL on my EK hatch! F*** QUAIFE!
MAKE SURE YOU HAVE THEM PULL THE JOINT THAT CONNECTS THE STEERING WHEEL COLUMN TO THE P/S PINION, AS ITS BOTTOM END IS BIGGER THAN THE MANUAL JOINT FORM YOUR MANUAL EK (P/S Civic users – disregard).
Whoever has P/S on their EK already, all you need is that Integra pinion gear/assembly. The manual guys will have to get what I got. But that’s$130 for a 3 LTL! AutoX is gonna be 10X more fun now, as is daily driving.
So there. I can’t believe it took so long for us to do this. Someone mentioned swapping internals over before, but I don’t think this is what they meant. This is SO straightforward and simple, I was surprised myself. I did a little alignment myself (the only thing adjustable is toe, unless you bought some camber links).
The steering wheel is now a bit harder to turn than the regular manual rack, but maybe only by 5%. I also have 205/50-15 Azenis RT-615 so that usually makes a difference. Stock tires are easy as heck to turn compared to those.
Bottom line - I’m lovin it. I am f-in MCLovin it. Turns are more fun, turn-in is more fun, everything is more fun. This is by far my proudest ricer moment.
Good luck to everyone who can now have quicker steering on their EKs!
