That's the same as about 47 miles-per-gallon using US standards. My goal is to get between 50 and 60 after all of my modifications.

have u ever think about motorcycle?

and what is that:
Civic VX EGR Control Box

[SVOboy]

The civic vx uses an egr system, which is the exhaust gas recycling things, and it basically reruns your exhaust through the system to lower emissions from my understanding of what it is.

that's exactly what it is. It is unique to the Civic VX (the control box). Some say that it actually hurts the fuel economy. if I can find other ways to lower emissions (hydrogen boost?) I might just remove the EGR assembly all together.

Either way, right now I want the car running properly, so I'm getting all of the needed components.

It's also possible that the EGR Control Box is a USA only unit, which makes me wonder if my JDM Engine needs it or not.

The EGR system recirculates the exhaust gas into the intake to act as a filler gas to reduce combustion. I had the vacuum line on the EGR valve on my old Buick clog up. Took forever to figure that out though. It was smoking horribly (filled up my apartment's whole parking lot with smoke when I stepped on the gas) and didn't smoke one bit after fixing the hose. Removing the system might have adverse effects, maybe it's not so bad after all.

Ah, so it essentially reuses the unburned gas in the exhaust? that's pretty cool.

I've been meaning to ask: How much weight do you lose due to the aluminum oil pain, or does it have some other purpose?

[dfoxengr]

the moroso's are probably heavier than the stockers. they are only really useful in road race apps, theyre not for losing weight, but to prevent oil starvation due to them keep the oil centered under the pickup

or if youre lazy and dont want to tap your oil pan for turbo.

just a bling item that you dont need to spend money on.
