NA S4 vs Civic SI
 

Pulled out into traffic, got behind an 06+ Civic SI... He gives it a little gas and sharply cuts to the left lane before we both have to stop at a light. He looks over and revs a little, I rev back.

I tack it to 6500, light turns green we both launch... I thought I was gonna have my ass handed to me, but I take the guy until about 80mph before he starts pulling up. Then we have to stop for light.

So what the heck people? I thought those things have some K series engine making like 200hp or something.

I was driving Mutaku's car (for those that know him) since he is in the airforce and his car has AC and a stereo :lol:

His car is all stock, 88 GXL with horrible LSD. Only mods it has is a home made cold air intake and airpump actuated 5/6 port. I mean even the exhaust is a smaller diameter than a stock exhaust :lol:

Civic was just an 06+ body style SI. Looked stock, no rims or exhaust or anything.

I did get an awesome launch though because I have been practicing lately. I am just wondering if the guy was maybe sandbagging. Any thoughts?

Civic si comparable to a acura rsx? I beat one of them last week with the vert. I thought he was gonna get me, but I get experience>performance? lol He had exhaust and lowered with a few gauges, so maybe some mods? Vert is stock with fireball exhaust.

Well considering there are several different K20s which is what the Civic Si has what is called the K20A3, this is what that makes:

These will highly likely walk you.

^this. my friend had an 2008(?) civic si that pulled on my na fc with a k&n intake and catback apexi N1 exhaust. seemed the driver of the si u raced sucked too since my friend launched his si good and once he reached 2nd gear he started pulling away slowly

^ Yeah I definitely got an awesome launch compared to him. Probably why he didn't start pulling until 3rd gear.

Thanks for the info guys.

I had fun with a newer SI on the back roads, the guy couldnt get me off his tail hahaha

You should totally find me a replacement LSD =P or find a place to rebuild it.

This is funny because i had a similar encounter, except i have a streetport, full exhaust, and a drop in k&n. I was merging onto the freeway and had a si sedan on my ass so i said what the hell?, downshifted to third took it to 7500 went into fourth to about 115 and was very surprised i had a 1 car lead on him? I didn't post because i knew i was probably going to get flamed, so i read this and said ok might as well. Btw good race.

Did you read his post at all? He raced an FG2 body Civic SI, not an EP breadbox Civic. Which means it was 197hp, not 155hp. He just out drove him off the line and got reeled in at the end. Good race.
