Actually, the 1st gens have bigger head poirting and and somewhat of a stronger bottom end. HP is rated at 195hp. Don't let that fool you though, its capable of withstanding 600hp with stock inernals. It also comes with the trusty 14B turbo. Head flows alot morte air. Some of the motors also have different cam angle sensors. The throtle body is bigger along with the intake manifold.
2g's have almost the exact settings, only differences are the turbo (T25 a.k.a T2small) and head work is a little more constictive. Also it has the 7 bolt motor which has the nasty reputation to suffer from crankwalk. Odds of happening to you are slim to none. But it may still happen....there alot more, but I'll let you do your homework...Have fun
