Ok lets look at a few more things. Look at how clustered this kit makes the engine bay look. Now granted I doubt this 2600 lb Si is still 2600lbs. Another thing is max HP isnt everything in the world. Some of the faster cars out there have lower max HP but they have clean graphs all the way through the power band. It wouldnt suprise me if this Si pulled a 13.5 or so on some slicks but still for 4000 ever realize what you could do NA? Probably close to 200 whp with an Si and some chasis lightening could probably bring that number to a low to mid 13 on slicks without compramising much daily drivability.
