Hello all, I'm wanting to eventually do an h2b swap into my dc, and I was going to see if it were possible to just remove the balance shafts, and to plug the holes without opening up the bottom of the engine for the dowels or anything. I have some plugs from when I bought a balance shaft eliminator kit, so I was wanting to see if it were possible to only plug the holes in the oil pump. I don't care about oil pressure because it's obviously not going to hurt anything to keep it the same. Any ideas?

 

If you take out the shafts, you will need to plug the main caps with solid dowels in a few places, and tap and plug one spot in the block. Also, the oil pump needs to be tapped and plugged too. The hardest part is removing the balance shaft bearing to tap & plug the block. Thats not very hard to do though if done right. Actually, the whole job is pretty simple with the motor out of the car. Definitely, this needs to be done if you remove the shafts otherwise there will be no oil pressure. Of course you could always leave the shafts in the block and simply prep the oil pump. But then whats the point in stopping there if you're going to the effort of pulling the pump.

Although, leaving the shafts in, and functional imo is the best choice. They have very little downside and lots to gain in terms of smoothness. Lots of the H2Bs I've seen have vibration issues (among other problems). The combo of solid mounts with no shafts can be enough to snap bolts. Not that taking them out is wrong, this mod has its place, especially for dragsters. Just saying, the engineers designed the engine a certain way for a reason. Removing part of the motor will not necessarily improve the motor.

 

Thanks for the reply! Yeah, I'll be buying one from hmotors, so I was trying to not rip apart the motor. Just hoping to drop it in, because that'll make me have to resleeve, correct? I'm guessing it won't be that much of a different with the parasitic loss, especially in a dc. Decisions decisions.

 

<p>There are kits which remove the balance shaft gear and not the shafts themselves. Check out the QSD eliminator.&nbsp;</p><p>QSD serves No BS</p>

 

Going in an Integra, you shouldn't have to remove them for clearance issues, right? If you just want to recover parasitic loss, simply remove the belt before you throw it in lol. It works just fine. IMO, the vibration isn't even that bad. I am using innovative mounts with their gray inserts

Edit: removing the balance shaft gear that's right behind the crank pulley, and replacing it with the lightweight KS spacer will reduce even more weight. That little gear is heavy

 

Thanks for the input guys! All extremely helpful. I'll definitely be going the gear removal route and just leavin the shafts in place.

 

I've wondered.....I watched kaizenspeed's tutorial a hundred times on installing their kit....

They make no mention of removing the balance shaft bearings on the timing side of the block (to plug an oil passage behind the bearing being the idea). I did not remove the bearing in my BS delete. Did all of you guys do this?

And OP, if it makes you feel any more comfortable, I (still, lol) have no experience in ripping apart and reassembling engines. This was my first time getting that deep into an engine because, well, this is the first engine I've tinkered on. After I got into it, it turned out to be WAY more simple than I thought. All my fears about it were over exaggerated and it really is just straight forward. What helped me is keeping close track of all my bolts I removed, and purchasing the KS Eliminator Kit. When it came time to reassembly, I just made sure I had the right torque specs and sequences, then put it back together. We'll see if I succeeded when I first drive it, haha.

 

<p>Did not pull any bearings myself either. Not sure what that is about.&nbsp;</p>

 

I had to remove the middle bearing at the rear of the block to get the tap all the way through, and to clean out the shavings. Made my own kit, this step may be unnecessary with the bs eliminator kit.
