Balancer Shaft Delete Kit

Need some advice of the engine gurus...

I've found a one off offer by a well known tuning part manufacturer to test fit/blog etc a Balancer Shaft Delete Kit for the FN2.

I've done some reading and the balancer shafts basically reduce engine vibration in inline four engines that are inherently unbalanced due to the cylinder firing order etc.


  • Has anyone any experience of doing this sort of thing to a K20?
  • Is it worth it or is it a bit specialised?
  • Will it make the car shake like MJ Fox?
The offer is to fit it all labour free etc, I'd just pay a reduced price for the kit as long as it fits. I don't know how much that is yet either...

Cheers in advance.

I would imagine less noise and less stress on the mounts, but I don't know. Removing the balancer shafts is going to be rough on the engine as a whole surely? Again I don't know.

Hoping someone has done it on a K20 really and can say what it is like!
 
Just had a response from the company, which has confused the hell out of me now.

EP3 and FD2 do not have balancer shafts. The FN2 does, as Honda wanted to soften the engine up. :confused:

I'm guessing I've asked a very specific question then!

Oh right. Why? :?

...the performance gained by the reduction in parasitic losses, there is also a useful increase in oil pressure.

Very small increase in performance I'm betting. Anyhow, they've already had a volunteer but neglected to put in the thread... it was Toda by the way, doesn't matter now it's not available. :lol:

What a waste of a thread! Will post up results of their test fitting when they put it up so at least there is a record for future generations! :rolleyes:

Sounds like a PITA anyway mate, any power will be minimal I suppose and at the possible loss of comfort like the ETD sounds like a waste of time.
 
Strange they are doing tests, we've sold loads of these kits for the FN2. Not heard any reviews/problems yet though.

Send us a link to it on your site mate, I want to have a butchers :) .

I looked but couldnt find it.

Very true, I was only interested as it was to be done free labour and cheap bits, I got all excited about it, then they tell me they've already got a volunteer and had neglected to post it on the thread.

I'd imagine it is a silly number of labour hours to fit this!

Que sera...

Because it's listed for CL7.

No info on it yet though, although is on Todas website.

Aye that's the one. The thread said it had good results on the CL7 K20, but it was untested on the FN2.
 
i didn't think the K20 had balancer shafts????!!!!

I've disabled (removed the belt and tensioner) the balancer shafts on my H22. It goes a bit better and there's less parasitic loss, but on low idle it shakes like Michael J Fox on his vinegar strokes. :(

It doesn't in the K20 in EP3, DC5 and FD2, just the K20z4 in the FN2 and CL7.

Cheers for the info on the shakes, that's the sort of info that I was after really.

I think that there may be easier ways to skin a cat.
 
i have this kit in the fn2, the car don't shake. There is a litle more vibration but nothing more than a normal car. It's like a stock EP3.
It revs much faster, almost as a lighter flyweel. The engine loses about 10 pounds, as the stock pump is about 12 pounds and the RRC pump is 2 pounds.

Thank you, good experience points there.

Makes you wonder why Honda would fit if it in the first place if it makes no noticeable difference.

Comfort, i'd imagine. The general rule is that balancer shafts are usually only required if your engine is an in-line 4 cylinder and more than 2000cc. :)

I did a video a while back to demonstrate that you can only feel the extra vibrations on idle :

you don't feel nothing of that in the fn2 at idle, as the engines mounts are very good stock. much better than the ep3 ones (i had also a ep3)
 
depends on what you class as a good engine mount. My idea of a good engine mount is something stiff (like a filled item) that allows less engine movement. I have a poly filled mount and it's a huge improvement over stock. ;)
 
This has been tested and offers around 10HP throughout the rev range. As far as I'm aware, the reason why Honda put the balancer shafts in the Z4 has more to do with the different oil pump assembly.

The biggest killer of Honda engines, especially the Kseries, is oil starvation, and I was told by a very clever Japanese man that Honda changed the oil pump because '' Engrish people do not check oil''

I do believe this is the reason why the Z4 has a different oil pump design, from what I have been told Honda wanted to reduce the risk of oil starvation and so they changed the pump in the Euro cars.

Good to know Lou. Any news from the boys South how long the kit takes to fit or are they still on with it?
