why thank you. were you at the last meet@ft.desoto?
yes, yamaha has been designing the heads for top end performance motors from toyota way back in the 2000gt days.
the 2000gt is sooooo badass for the time that is came out.
the 1g-was offered in gtte, ge, and fe head designs i belive.
the same with the 1jz.
this is funny, i was hell-bent on getting a 1g-gtte for my supra, thinking ya know, 2.0 high revving straight six. get some lighter pistons, high profile cams, stiff springs and harded valves and rev it to 8-9k rpm or more. than i found out that NOBODY makes shit for that motor AND it only has 197 hp. screw that in the 3500lbs tank.
