well what do you want?? i'd personally go for the IS /c it's nicer...but that's just me...it lacks the power it should have...but a 2JZ swap is alright, but you could just turbo the 1JZ that's in it...
but the Neon Srt-4 is on, fast from factory, faster than the IS...but 2 totally different cars...i like the luxery of the IS...i test drove an 04 IS300 with 3 miles on it...very nice...smooth all the way up to 120 with no noticable sound or vibration
but i like this 2JZ swap with NOS
