Here's a video... if you check this tonight, prob need to wait until it finishes processing on youtube's servers...
Should give you a better idea of what a fully enclosed radiator/IC looks like. Full shrouding in front and back of those units. The laminova unit, you can see it behind the radiator sitting atop of my splitter... the laminova unit is mounted along a large aluminum piece which itself acts as an additional heat sink / dissapation point, which was a pretty trick move by the guys at CIN motorsports in Charlotte... they put a lot of time into this shroud and setup and gave me a great deal!
I didn't research the GTM kit, but I'm guessing the package they have will ultimately cost you less if you DIY the install vs going full custom like I did
Not enough data to report on what size laminova unit at this point, I went big / dual core... I do recommend stuffing in a thick radiator replacement if you're going to delete a/c and redo the cooling and the shrouding is a BIG DEAL... also there's a setting in the nissan computer for when the fan's kick in... have your tuner play with that so both kick in at 190-200... if you get energy efficient fans, should be able to run stock harness no problem
