Re: Chassis bracing

There's so much metal in between the rear strut tower braces that I don't think there will be any twist there

If you have sunroof, remove and weld a plate. That will stiffen chassis more

Good points. There is quite a bit of metal between the strut towers in the back. Also, I don't have a sunroof, but I'm sure it's not good for rigidity.

There was a subframe Brace too but I’m not sure how well it worked.
Thanks. So you're saying that you felt an improvement from a rear strut tower brace? Also, you're right that the subframe is obviously quite solid already, so I don't really see the point in bracing it either.

Re: Chassis bracing

I never had a rear strut brace for the car but considered getting one.

To clarify as I just re read my post and realized it made no sense. I had a rear subframe Brace (Progress) and l don’t think it did much. Companies used to make front subframe braces for the EM2 that looked like they might make an improvement. The general consensus when I was researching it way back when was a front one helped. None of this is scientific of course.

What's so special about Honda power steering fluid?

I just put my power steering system back on, and I filled the system with ATF because that's what I have extra of. I know I'm technically not supposed to, so there's no need to tell me. I've used standard power steering fluid, as well as ATF in Honda power steering systems for years with no problems, and I know other people that do too. What's different about Honda power steering fluid? Is the viscosity different or something?

Re: What's so special about Honda power steering fluid?

It's what the pump and rack are designed to used., problems may develop if the wrong fluid is used. Like putting the wrong viscosity oil in your engine, it may work (for a bit) but eventually it's going to cause problems.

Re: What's so special about Honda power steering fluid?

I've seen problems when people put PS fluid into a system that calls for AP4 ATF. The system makes very loud squealing noises.

But I can't recall ever seeing someone us an ATF in a PS fluid system. Perhaps nothing goes wrong in this situation as you have mentioned.

Re: Chassis bracing

What will help is a tie bar between the seat belt top mounts.

Even more so if you're running no rear seats then you can run a bar between the seat belt mounts and then an x frame to where the rear seats used to be.

The owners manual specifically says to never use ATF, and if normal P/S fluid is added in an emergency, the system needs to be flushed and filled with Honda fluid as soon as possible.

Yes, I understand. However, what I'm asking is what makes Honda fluid different than standard fluid.

Can AGM batteries leak acid?

I noticed a small amount of clear liquid by the negative terminal on my Optima Yellow Top D34 battery. I don't see how water would get there since it's mounted in my trunk, but I don't see how acid could leak out of an AGM battery either. The battery is from 2007, but it still works fine. I recently had it tested, and it tested at above its CCA specs. I wiped the liquid off and tilted the battery and nothing leaked out. Do I need to worry about this? Thanks.

Re: Chassis bracing

They are known sometimes as "seat belt bars" or "harness bars". I'm not sure if there is a company who makes them for 01-05 civics. I've seen them for EP3s (type r), DC5s (rsx) and older EG civics.




there are also c pillar x braces, but these mount in the rear, not off of the seat belt posts. With how the em2 is made I don't think this would be as effective as it is in hatchbacks.




Then you have half cage roll bars.

Re: What's so special about Honda power steering fluid?

There is the possibility that it is marketing, to increase sales of honda branded PS fluid, or customers returning to honda for servicing.

There is also a possibility that the seals used in the honda racks are prone to damage from certain chemicals found in other types of PS fluid.

There are PS fluids that list safe use in multiple vehicles as well; everything from BMW to Gm to Honda.

Re: Can AGM batteries leak acid?

It was probably just condensation. Heat can build up inside the battery and when it escapes it hits cooler air and condensates. If it tested good then no need to worry.

Ya know what's funny......It's damn rare to see power steering issues on certain cars, but when we do see a specific failure on those particular cars it's almost a given that it's been serviced elsewhere.. Draw your own conclusion from that.

I agree. However, I take more risks with my cars than I would with someone else's car. I would NEVER do something questionable to a customer's car.

Ok, thanks. I guess if it does it again, I could sprinkle baking soda on it and see if it bubbles. I'm not sure if it's even possible for an AGM battery to leak. But yea, the battery tested good, so I'm not too worried. I don't remember the numbers, but the CCA tested at well over what the battery was advertised at.

Sure they can leak acid. AGM part just reduces chance lead plates break free and short out.

I thought the acid was absorbed in a spongy material, so therefore it can't really leak?

UPDATE: Apparently AGM batteries can leak acid. It did it again, so I put a pinch of baking soda on the liquid to test it, and it's acid. I think it's broke after 11 years. I cleaned around the terminal and smeared silicone around it to try to seal it. Hopefully it quits leaking.

How do throttle body spacers work?

I'm confused about how throttle body spacers work. I know that they go between the throttle body and intake manifold, but why would that help anything? They claim more power, torque and MPG, but how do they work?

Re: How do throttle body spacers work?

Originally they isolated the metal carb from the “hot” steel intake.

Since our cars have plastic intake not really a heat transfer issue, in fact our cars pump coolant into the throttle body to warm it up / keep it from getting too hot.

As long as it comes with a cool sticker, you can get something useful from it.

Actually, mine has an aluminium intake. I presume a TB spacer wouldn't do any good though.

Re: How do throttle body spacers work?

Since it's after the TB they also, in effect, increase the manifold plenum size.

This is more important for older vehicles when people "tuned" physically rather than with software for N/A builds.

Back in the day if you wanted to jack up your fuel intake by adding a larger carb. then you needed (for some vehicles), to increase the flow of air into the engine. So larger throttle bodies, intake manifolds, intakes and TB spacers where used to try and match the air flow to the fuel flow.

People still do this but tunable ECUs make it much easier to match air and fuel ratios.

Would more plenum volume be a good thing on a MPFI engine? I thought a larger plenum volume would deaden throttle response. The whole point of ITBs is to basically eliminate the volume in the intake manifold that's under vacuum. The less volume under vacuum, the faster air will fill the space and the quicker the engine will respond to throttle.
