Wow, I couldnt believe how much more the Si weigh's. My reason for this is that a guy @ a local shop was trying to sell me some Neuspeed spings for my Si. He told me that they are for all 06 Civic's including the Si. Then I did my homework and saw that pretty big weight difference and went with the Tein S Tech's(for the 06 SI).

 

yea, it's one of the reason why i got the dx. weight. 2593 lbs baby!!

 

bigger motor, different tranny and LSD all make for a night and day difference between the si and the dx. not really comparable if you ask me

 

Unless you're thinking gas mileage!

BTW -- I just did 369 miles on something like 12.4 gal.

I can do 370 on 12 with my ep3 that happens to run 13's as well.

 

There are a bunch of differences in the two cars from the DX and the SI. The suspension points are different for one. They are moved on the SI for better handling also there is more chassis strengthening in the SI than the DX. If you plan on making a DX into an SI you really can't. Honda put a lot of effort into the SI when they built it.

 

lighter but slower.... so how does that benefit you?

By the time you try putting a K motor in your car, your going to weight almost the same as a SI and still not have all the features as a SI

 

so the k motor weigh 300 lbs more than the r18??

 

about 140 pounds more give or take a few for the motor. The rest is electronics suspension and other odd and in's.

Yup

Bigger motor, Tranny, Rear Disc, ABS etc etc

hell even the Si exhaust tip ( s2000 ) is "hefty" lol

 

how much does the k20z3 weigh and how much does the r18 weigh?

 

stereo, ac, and rear disk brakes, sunroof, and tons more

 

I believe that Si models have always weighed more than the DX trim. Although not on such a great scale as this... It's the price you pay for getting the top-of-the-line model w/ the best resale value.

 

I'd add AC and Sunroof as two other significant contributors...probably at least 100 lbs between the two, leaving 40lbs for suspension and electronics which seems more reasonable.

Between the EX 5 speed and the Civic SI there is 176 pounds difference. So the K20z3,6 speed tranny and suspension make up the 176 pounds.
