Exactly, Greddy kit differs in the blue box and the downpipe depending on the year.

In terms of the Drag kit, it actually does come with piping that will fit to your application. So if you order a GSR kit and you have a GSR, that piping will slap right on, no need to fabricate anything. The LS TB also sits in a different position than the GSR TB, so if you got an LS kit the charge pipe to the TB will sit a bit different.

Drag kits come with a Vortech FMU and inline fuel pump last time I checked, but you dont want to use that for your fuel management. Better off doing it right from the beginning and going with Hondata/Neptune/AEM etc.

And as for those Greddy #'s, unless thats at 10PSI+, I wouldnt expect that.
