Hi there,

Just ordered a set of 4.56 rear gear, any know a good place or trusted mechanic to install this in the Netherlands or around ? Can honda dealer handle this kind of instal ?

Rgrds,

there is 1 guy in Belgium who did it, the gears were installed at Racetech

http://www.racetech.be/

 

No matter how much reputation an installer, mechanic or shop has, ask them this beforehand:
Do you want me to supply the OEM shim kit?
(that shim kit is pretty expensive )
What if the shims in the OEM shim kit do not give you the contact patch you want?
Do you have (or have acces to) a machine shop (lathe) to make a shim?

Most would not ask any questions, they would supply the diff and the new gear set.
A good mechanic would always have an answer to the question: "What shim did you end up using?"
IF the answer is: "The shim that was in the diff" you may run into problems after a while as the gear set wasn't properly set (pinion depth that is).
If they say: "We used the shim that was in the diff because it gave the correct contact patch and THAT's why we used it" .. you know you're talking to a proper mechanic.

Tip: replace output shaft seals while the diff is open.
The rear seal is a must as you will destroy the old one while removing the smaller pinion outer race / bearing.
And get a new crush sleeve & locking nut.
Mandatory IMO.

 

Hi there,

Thanks for the good advices ! Suffice to say I'll get into a proper "investigation" before I allow someone to put it's hands in my diff housing.
I heard many stories on how this operation is of the sensitive kind and the effects it can have.

Thanks Graphtuner for the link, I'll sure reach them and ask some questions. Do you know if the owner that swapped it's rear gears at this place was satisfied ? Any obvious wine or problem after ? Maybe, if you agree, there is a way to get in touch with this person, just to know how is experience was ?

Thanks Spitfire for the advices. Indeed I made as much homework as I could reading as much posts about this subject I could fond on S2KI.
I'll try to find a place that can actually modify or make the proper shim if the Honda set doesn't provide with the proper pinion depth for my application.
Very good point on the seals, I'll have to pay attention to this.
For the crush sleeve and locking nut I can't agree more with you, this is on my ist.

By the way I heard of a place called Kempower in Belgium, not far from Circuit Zolder, anybody ever heard or dealed with them ?

Thanks again for the feeback,

Hi Miran .

Very Nice Write-up ! I came across it when I was investigating the subject of the rear gears. Very interesting. I wish I had the time, space, and skills to do it myself, but I'll have it done once I'll have received the parts and found a proper place.

Thanks much for the feeback,

Question for HeavyRightFooT: did you read the topic on s2000.be, IOW do you understand Dutch?

If so, the top speed of the 4.57's isn't anywhere near 256 km/h.
More like 241 km/h, in 6th @ redline.
Top up or down doesn't matter, that is true.

You will like the 4.56's
IMO how the car should have been made by Honda.
That is the only thing they got wrong.

 

Hi SpitfireS !

Welllllll .... I dont really understand Dutch .... I'm hard at work taking private courses but it revealed itself way harder to learn than what I expected ....
I tried to get thru the post on s2000.be but it's quite a difficult task for me ....
I registered to the forum to be able to post and PM the author of the thread to have an idea of his experience and install feedback, but for the moment hadn't got the access.

I don't mind loss of max speed, I'm very very rarely hitting the 6th top end... I tried hard a couple of times on the autobahn, and reached around 260 at the speedo ... and that's about it ...

I do think that the S could use a shorter gear ratio, but to me the 4.77's are a tad to compromising in terms of highway cruse. And I'm more interested in exiting a turn fast than absolute top speed.. So I ordered a set of Richmond 4.56 gears from Rick's about a week ago, that sound like a reasonable point between cruise and accel, and while the shipment is in transit I'm investigating on which place to have them installed in... I got some addresses from friends, relations here, but I'm still investigating where to go to. I already got a hanfull in Belgium, and I don't mind driving there to get a proper install done, but seen that there is a decent race crowd here in the Netherlands I'm sure there must be some decent places to get that done....
I also just received a spoon baffled oil pan from Takakaira in japan, just to try to counter any oil starvation on track days without having to go full dry sump.

Anyway I can't wait to have them installed and be able to testify against all the good posts I read about these gears. Time will tell ...

Best Regards,

HRF
