i think they are freakin beasts...amazing low end torque....good look...good car overall...nissan did well...TT it and you got urself a skyline opponent...but...
-working in the engine bay of a Z sucks ass...be forewarned
-example: it took me and my buddy 3 hours to get CAI on
-parts = $$$ .... lots of it which is common knowlege...the more $ ur car, the more $ aftermarket parts for it are
-that's a lot of money....
+you'll have a brand new "never worry about" car
+starting stock kicks ass
+ur already dominating ur old car by over 100whp just to start
so in the end it's really up to u...personally i'd keep the teg cuz i like "toys" just do everything u can to it and take care of it....
