Sounds about right Andy.
Stock GTR33's do qtr mile in what 13.5 or thereabouts(with a really good driver/launch off the line).
Your car sounds stockish with just bolt on mods running stock ecu and stock turbos unless i read it wrong.
So with your current mods, pod/zorst, ebc, s-afc. you should be doing 12.5 to 13flat qtr mile with a good launch (MY GUESS).
So if you said that EG does 12.6-13flat down the qtr-mile i'm not surprised you lost.
EG Hatch with B18c (Dc2R engines) do around high 13's to 14 flat qtr mile (dunno about mods but there is a yellow eg running those times at wsid)
EG Hatch with JDM K20A (with stripped interior and bolt on mods) did a best of 12.3 qtr mile with drag tyres, plates: EGK-20A (blue one) engine has now been transplanted to a integra though.
my 2cent. (i could be totally wrong but thats my opinion)
