EK9 Facts and Myths


Is that prefacelift 96-98 or facelift 99-00? Honda usually has different/improved options.
My lads ek4 is a facelift e-ek4.......i know its nothing to do with it but the reason i had to check.... he has a pre-facelift front bumper on it! :nice:
 
Stupid me....of course 6/8 is 3/4.....so it was more like 7/8.....

Sorry folks, and no one pointed it out, it dawned on me i was being dumb :slap:
 
I've checked LTL and my result is in line with what has been recorded so far - 2 and 3/4 or thereabouts. Interesting to hear the strut brace might be different as well, this is the first time I've heard it. I've stuck my EK9 strut brace on scales and it weights 1630g, anyone with EK4 willing to weigh theirs? TBH I would be surprised if they were different, other than the colour of course but I could be wrong! BTW all my measurements are done on pre-facelift EK9, standard model (i.e. not a race base model)
 
Strut brace is different, I'm 100% sure of this,
(I have a ek4 sir and a ek9)
Also the ek4 has no rear crash bar, it doesn't even have holes to bolt it to like the ek9 does
 
My EK3 also didn't have a rear crash bar, yet others say there is a crash bar on some EKs? I also vaguely remember there was not even a way of mounting it! There is probably more variation than we think. As to the difference between race base and standard model, anything with red carpet and Recaros is standard regardless of what other options are present/missing. Race base had the cheapest seats, interior and steel wheels as far as I know.
What is different about the strut brace, other than colour? Just the thickness of the pipe?
 
Fact: The factory strut brace on an EK9 is heavier than an EK4 from when I weighed them it was over 700g difference and you could visibly see that the tubing was thicker.

Definitely true... see this post: http://ek9.org/index.php?threads/ek4-x-ek9-upper-front-strut-bar.65242/

Reference the steering and turns of the steeering wheel LTL
Just did this a moment ago with my lad who has an EK4 which i fully beleive is standard rack...

EK4 = 2 and six eighths
EK9 = 2 and six eighths

Both have standard steering wheels, but the Momo is smaller, so is it just that it feels less on the 9 compared to the 4 because of this reason......the hands have to travel less distance when turning?

This would mean that the EK9 rack is a quicker ratio... the steering wheel being smaller would require more turns than a larger steering wheel to go the same distance.
 
Nice! I've checked the part numbers for the two strut braces, EK9 strut brace is 2.5 times the price compared to EK4 as well!

That's not correct, you count how many times does the steering wheel turn from lock to lock, size of the steering wheel has no effect. You could take the steering wheel off completely, count how many times does the steering column need to turn and would still get the same result. Smaller steering wheel will react quicker because the distance your hand has to travel is smaller when you turn it, but it has no effect on how many times you need to turn it!
 
I disagree. It's the same thing as with gearing, pulleys, valve knobs/wheels, etc. The smaller the diameter the more rotations are required for the same movement at the other end. If the front wheels are physically being turned the same distance (inward to outward) and the steering wheel is of smaller diameter it would have to make more revolutions if the gearing/ratio is the same. You can also think of it as you do wheels. A smaller diameter rim and tire will make more revolutions than a larger diameter rim and tire in order to travel the same distance. It throws your speedometer off when you have improper sizing due to everything else in the mechanical assembly being the same.
 
Ok, the steering wheel is just an extension of the pinion on the rack, right? If the pinion turns let's say three times from lock to lock, so will the steering wheel - they are on the same "axle" so to speak. The variable here is the distance your hands have to travel as you turn the steering wheel, not how many times you turn it!

I agree, the hands have to travel doesn't equal to the pinion has to travel from lock to lock. It's the leverage that changes.

Agree..... imo the pinion still turns the same amount......regardless of the size of the wheel.
In terms of gearing as mentioned by @ImmortalOne, doesnt this theory meen the larger wheel just 'makes it easier to turn'....but the same revelutions on the wheel....
Crikey this is doing my nut in....think im just going to have to contact Honda HQ and ask!:angry2:

Agreed... you are correct. I was thinking of it wrong. I was thinking circumferential distance rather than degrees of rotation. The difference in steering wheel size would only affect effort required to turn said degrees, not the ratio itself.
 
The strut brace is thicker for ek9. Not sure about the actual pipe but the brackets are most definitely thicker.

Both my ek9s have had a patch of sound deafening in the drivers footwell.
 
Anyone has pics of this ?

I'm very interested in seing differences with ek4 subframe and arms.

My brother had a Dc2 subframe and that was just spot welded all round. Ek9 one is solid weld all the way round bar afraid tiny places like an inch long.

I'll take a picture of the subframe for you today, now is a good time before the engine goes back in! I thought all suspension arms were fully welded? Anyone else has seen any difference in suspension arms? I'll see if the part numbers match those on other EKs...
 
Lol on the rack discussion. The strut brace is interesting. Happy to photo ek4 bits if needed.
 
Also I have the rare racebase manual rack - so I can tell you how many turns that is.
