hey i am looking for what speed does a 2005 honda civic si engine shut off at? what is the max mph?
i have gone that lease 120mph in it, and if you change it or mod the ecu can you change that?

 

You really dont want to go any faster in a car that size. Alot of people dont realise is that most tires arent even rated for 120 mph. If you ever go out to look for tires look for the highest speed rate. Tires are the most important part of high speed driving... then there is suspension and weight and all of that... but if a good gust of wind blows and your going that fast, well, your going to die happy at least!

 

Only drive it as fast as you can trap in a quarter mile.

 

well first let me say this "i dont mean to come across like ******* but i am"
tires and suspension yes! but speed man come on in. that car i can get up to 110 with out even trying and on street roads. driving fast isn't it what it is all about? prettymuch?

yes the car only weigh's about 2200 but that just means i need to eat more!haha

sorry man but nobody answered my (?"s)

p.s. **** dieing

 

sorry "superman" but that car weighs about 2700 lbs and they are not that quick so you have to try to go fast around city roads

p.s. the speed limiter is 130 and it has 160 hp

 

"superman" why didn't i think of that! lol

thank you for answering my '?'

 

Correct me if I'm wrong, but I thought the Si model only has 135HP while the SiR model has 160HP.

 

they are the same motor....in the 99-00 SI's its the B16A2 and in the new SI's its the K20A there isnt a power difference in the two, actually there really isnt much of any difference(SI and SiR)

 

is the speed limiter built into the ECU or is it a mechanical thing?

 

I'd like to find out more about this info because I'm looking at purchasing an Si. A salesman at Honda told me that the 2001 and up Si model only has 135HP. I see info about the older Si models being 160HP. Now I'm getting conflicting info. Can someone please help me out with more info on the Si HP ratings?
