I traded him that intercooler.Its 4rdrwhore's old one from his gvr4 and good for what your friend has until he upgrades.We used a similar core on a gst a long time ago with a 14b,afc,exhaust,wally 255,and clutch and the car went thru a set of nitto drags in 3 weeks and ran 13.7@107 on his first pass ever at a dragstrip.Tune it and max the 14b and then think about upgrading.
