Time for some boost!
I used to have a 2000 tiburon with a few bolt ons that ran a 15.4. Go to the track and see where you stack up.

When I had a catback exhaust, intake, lsj throttle body I ran 15.5. Now I added downpipe/header stronger tune and now I'm running 93 gas. I'm hoping for at least a 14.9

My car actually ran worse than stock after all the bolt on's before my tune... I may have been a little over zealous with prior statements but it def feels like a new car.... the way an NA car should run stock as far as im concerned

SS/SC are all manuals.

Stock SS/SC's put down between 210-215whp & 185-190wtq on avg.

You are not near that.

I do want to congratulate you though, because I know how fun it is bringing out the potential of these cars.

Which cavy is yours? The white one or the silver one with the black rims that have the purple lip on them?

Cavy's are light for sure.

I wish my Balt was as light as my 98 Cavy RS (2600 or so lbs).

SS/SC was underrated, the 2.4 was not. Most SS/SCs will dyno around 215whp. You're probably sitting around 150-160whp.

They were underrated from the factory.

If rated correctly, they would have been around 230-240bhp.

Truth. I've seen them as low as 200whp or as high as 220whp, but most fall between 210-215whp.

They are rated correctly, and usually put down around 235-240whp stock.

The rating standards changed between when the LSJ was rated (2003 I think) and when the LNF was rated (2007 or 2008).

Many many "performance" cars were underrated before the new standards when into effect. Lot of debate over whether it was to make customers happy, giving them more power than they expected or whether it was so that insurance rates would be lower. Either way the new standard doesn't allow room for underrating engines anymore.

I wish I still had mine, I miss that car like crazy. Traded it in when I got the SS.

Yeah I've seen both around. I remember running the white cavy on my way to bellevue one time a while back. Texted troy who you know and said you were in the passenger seat. I'm the one with the red 4dr s/c with the auto shitbox.

Yeah, they are great cars.

It was the first car I modded, haha.

It's stock again other than a Vibrant Intake, Airaid throttle body spacer, and Pacesetter header/downpipe combo. It used to run circles around my buddy's lightly modded (intake) Z24, haha.

Mine was unmolested. It was my high school/college car. First new car I ever had.

There was only a 10hp different between the two in 98.

I sold mine at 115,000 miles, ran into the guy who bought it, and the car lasted till 275,000. Not bad for an econobox.

Yeah, my first Cavy (1992 RS) lasted until 230k before the kid I sold it to wrecked it.

Good little engines.
