Well i was just thinking about this the other day. I know that HASport mounts come with the really strong/stiff bushing that is ideal for racing. The only problem that some people have is the fact that they cause the ENTIRE car to viberate.

*can you swap out the bushings for OEM pices, for a quiter, less engine bay viberation?
*has anyone ever done it? which OEM bushing to use?

***if it really don't viberate that much as some have told me, please tell me your experiance with HASport mount.

 

I like Hasport mounts. they have a basic urethane and the race urethane. get the street kit urethane. it will vibrate somewhat still because it is urethane. not much can do about that. unless you do a weld job and go factory integra mounts.

 

wow i didn't know that they offered two different firmness of untrthane bushings.
* i always though that i could just press bushings out of the mounts and install OEM bushing...hehe i wounder if anyone has ever done it?

does anyone know if the bushings can be swaped out with OEM softer one? I don't wanna be riding in a car that rattles that much.

 

Then don't swap a B motor into an EF chassis.

 

How do you know if you have the race or the street version?

I just ordered Hasport h22 mounts, but I wasn't asked if I wanted race or street.

I didn't even know there was a coice....

How can I tell before installing them and having dashboard shaking vibration?

for whatever its worth, I have the hasport h22 mounts in my 92 VX and the dash does vibrate like hell in the really low (600-1200) RPM range.

I just figured thats what you get when you do this swap

 

There is actually three stiffnesses of urethane available from Hasport.
62A, 70A and 85A.

70A is what most of the other companies use. 62A is the equivalent of a factory engine mount but without the voids or fluid fillings, so it does feel stiffer.

We have found over the years, that anything less than 60A and the bushings fail pretty easily. We are working on a softer stock like bushing, and expect it to be out some time in November. It will require us to change the design of the mount though.

In the mean time we do offer the softest bushing onthe market.

thanks for clearing it up!

 

Brian;

First off; I'd like to say that I deeply respect the quality of parts that your company produces.

I have to assume that all of the manufacturers of mount kits use urethane due to it's being easier to produce than a rubber item. However, it seems that when asked (and they are truthfull about it) most people are unhappy about the vibrations! Even the May issue of Sport Compact Car (B18a in an EF) comments on the added vibrations.

Why is this deemed exceptable?

How about doing a four point mount kit using rubber bushings! In looking around, I found a readily available bushing that should make the mounts possible and also cost-effective. It's a Jaguar chassis bushing, number MNA 2370AA. They only cost around 27 bucks from the dealer. There is a smooth outer and inner steel collar. As such, they would be replaceable. The rubber section has less "voids" than the factory mounts and as such, would be firmer than the stock mounts.

I must admit I'm kind of annoyed.

Before I shell out 500+ for a h22 mount kit, everybody tells me 'oh yeah it'll vibrate for like a month until the mounts get broken in'.

And now I'm just reading that it vibrates....all the time.

Is it true that the vibration doesn't go away, that they don't 'break in'?

If so, I'm gonna be one mad boy.

 

I don't know who's tellin you that, but I didn't have vibration problems or even this "break in period" with my mounts. At low RPM's its a very slight vibration, but it's really nothing, the rest there is no vibrations.

 

Well if my car is a rattle trap I'm selling it

I can't STAND vibrations. it's sooooo freakin annoying.

What is the extent of yours? Does it shake the whole car?

 

Please don't turn this string into a arguement as to how much vibration is exceptable or not. Some people will say that it's not notable and others will complain. (I feel that I'd fall into the latter) It is VERY rare that a car magazine would make a negative comment about something that they are writing about and that is why I pointed out the comment in Sport Compact Car.

It should be noted that Honda NEVER used urethane motor mounts, and this includes their high performance vehicles. As such, I have to conclude that there isn't an engineering reason for going to urethane (and is manufacturing costs or not wanting to use all four stock mount locations).

I put my comment in here with the idea that Brian G (Hasport) may see it. If a significant amount of individuals state that the amount of vibration that is transmitted to the car IS a major factor in who's mounts they buy, then it may put pressure on companies to make mounts that don't vibrate more than the original car.

Manufactured rubber bushings ARE available at a reasonable cost that could be used.

For the price we pay for a mount set, I don't think we can really complain too much. Honda has spent untold $ on research and development. Look at their mounts, they are designed to be soft and not transmit vibration. There are some other things we must consider, most big 4bangers have balance shafts, why? the inline 4 is going to shake, the bigger, the more shake. Someone produces a "soft" conversion mount, we put in a drag car and it doesn't work so the mount is no good! It seems to me Hasport and others are producing a race/street mount with a nod toward performance, so we should expect some vibration. FWIW there is no "just like stock"-not in shocks, springs, poly suspension bushings, or motor mounts. And NO, my greddy is not as quiet as stock!
sorry for the long post, just my opnion.
