I believe the GT-2 units have only slightly better performance than the base units (roughly 10-15% as I have been told). It is not worth the labor to install them for this small incremental improvement.If you are going to tear the rear bumper off and mess with all those hoses at least install an IC that will provide cooling for much more boost.

 

NOT WORTH THE PAIN and $ to do the swap between stockers and gt2. Its not a 10 min job. As many have said. The entire rear clip has to come off!! If you gonna strip the car let it be worth it. Get something way better or dont do at all!!

 

mine are still forsale..

 

i had Blown6 coolers and they worked great !
