There has been a lot of controversy about the elimination of the balance shafts in our H22 engines, the main one being that people don't want the HASSLE! Well all I have to say is what hassle? It is really, pretty damn easy. I had custom aluminum plugs made that press into the oil pump to block the holes that the balance shafts pass through, and then all I did was remove the locating tabs from the balance shaft bearings and rotated them so that the oil holes DO NOT line up, to block the oil ports to the bearings, thus not losing oil pressure! I have succesfully done it on the last 2 H22's I have built, the first one, the prototype being mine! Both engines idle, run, and REV like stock, with NO noticeable additional vibrations!

The two main BENEFITS from eliminating balance shafts:
1:Increased horsepower due to less reciprocating mass, just like a lightened crank
2: Increased oil pressure due to the oil gallies that run to the balance shafts being blocked

I hope to have an engine that the only modification done will be the elimination of the balance shafts: so that I can be able to show how much of a horsepower gain, and how much of an increase in oil pressure (however slight) you can expect to see.(more oil pressure, always good )

stupid newbie question : Can this be done without removing the motor from the car ?

Yes it can, but you would have to remove the oil pump to press the plugs in, and the oil pan to get to the balance shaft bearings.

I would also like to see how much oil pressure would be lost if just the plugs were pressed in, without blocking the oil to the balance shaft bearings.hmmmm... possibly not needing to block the oil passage and make for a quick install; I would of course always block the oil passage until that is proven OK however!

I may look into a set...

based on the debates surrounding this modification, that may not be the best analogy to use to promote your product

I agree, but ask any full on all motor guru, and they will tell you the same. Instead how about: "just like underdrive pulleys, lighter, less reciprocating mass!"

ludesleep

man if i knew for sure that eliminating them does not hurt the engine or put more stress on the crank and bearings i would buy them. Im running around or soon to be running 400hp so im kinda scared

H22Prelude

Will this have any different kind of effect (good or bad) on a boosted H22 compared to an all motor H22?

TimeRacer

These balancer shafts are solely for idle quality. W/o them at idle you may experience a little more vibration (depends on how stiff your motor mounts are) but they have no bearing upon engine life.

Boostless97Lude

i ordered a set, haven't gotten em yet, but i am looking forward to installing them

CHK4TIX

ok, here another newbe type question, do i have to take it some place to get them pressed in or would i beable to do that with the average tools that most people have on hand?

Boostless97Lude

take it to a machine shop

poison

Looks damn good! I'll be looking forward to getting 'em soon from ya

I don't mean this to be a plug for the parts, as we did make 200 sets. I mean this as a tech thing to answer any questions. BUT if you want a set, they come with DETAILED INSTRUCTIONS, and are just $40 shipped. PM me or paypal to: Turbo24u@aol.com , they will ship next day! </TD></TR></TABLE>


ok when you said...and then all I did was remove the locating tabs from the balance shaft bearings and rotated them so that the oil holes DO NOT line up, to block the oil ports to the bearings, thus not losing oil pressure!....


i looked at my block just now and i dont see any holes? Are the h23 different?...Im gonna buy some off you as soon as i place my order tomorrow...you accept credit?

Daemione

How much do the balance shafts weigh compared to the plugs?

Greyout

I thought I was insane also - but when looking in my H23, I didn't see any bearings or oil holes... When I took them out, no bearings came out...

Greyout

really - am i just a noob engine builder or are there no bearings or oil holes on the H23 balance shafts?

ludesleep

im looking at mine now and i see bearings but no holes

Greyout

if I am infact a n00b and there ARE bearings in there, I would feel better about taking them out and sealing the oil passage off with a dot of JB weld or something. Wouldn't want a bearing to fall out of there....

well hell. It all felt like part of the block to me, there was nothing that slid out like a normal bearing...

why does that matter??? the point is that you are simply removing rotating mass, not weight in general

The oiling holes on the bearings are VERY small. However you guys are saying that you don't even think that there are bearings!??These instructions have been based on my knowledge of the H22 engines, and these balance shaft plugs are for the H22a (jdm spec), H22a1, AND H22a4, instructions are included!

I will DEFINITELY check into this H23 mystery about the balance shaft bearingsand see what I find out! I will let you all know!

As for engine reliability it is ABSOLUTELY NOT AN ISSUE. The balance shafts counteract how you FEEL engine vibrations that are natural to all 4 stroke, 4 cylinder engines, which are prone to vibration at certain rpm points. The balance shafts also ARE NOT solely for idle quality, in fact at idle is probably the time you will be the least likely to feel engine vibration that would be due to balance shaft removal. I just had a long conversation with the engine builder that I consulted before trying this product on MY OWN car, and that is straight out of his mouth,... and he has been building RACING engines for 30+ years, I assure you he states from experience!

I can also vouch for that, my car purrs and idles absolutely like stock without balance shafts, I can't wait for some of you to remove your balance shafts with these plugs and hear how amazed you are at how it still idles and revs like the balance shafts were still there!

As for installation: ANY machine shop should be happy to install them, and should only charge $20 AT MOST, as it will take less than 10 minutes. It would be possible to install with a vise, but it is recommended to install with a press (even a cheap harbor freight press works perfectly, these plugs are a .005" interference press fit, freezing the plugs and the oil pump casing is helpful.

So lets recap: Idle quality NOT affected, CAN install yourself, but recommended to take to a machine shop, no negative effect on engine reliability, gains should be the same whether engine is turbocharged or naturally aspirated. Keep the questions coming and I will do my best to get you TRUE answers based on fact and not B.S. I am going off of what I KNOW based on MY OWN CAR and the customer car I did as well, not to mention the engine building knowledge of my machinist!

just to verify his experiences, a friend had a balance shaft belt break on a 4G63 in his 2G eclipse, and it felt no different until he found the broken belt later on.

It matters because all that needs to be done to disable the balance shafts is remove the belt. The only advantage to removing & plugging them would be weight savings.

So I'd like to know how many pounds off the engine my $40 + labor will be worth.

And of course, if some A/B dyno testing could be done, I would be as interested in that as everyone else here.

Boostless97Lude

the best adavantage for this is when you already have your engine out and aprt, like mine
