Sorry to butt in but Id like to share my turbo teg too… Its still needs lots of work and finishing touches… i like your car nice and clean. What top radiator mount are you using??? 
i wouldnt think it to die out, ever ride in a dsm with a t25? they pull hard till 7k rpm redline which is higher then ours and has a 2.0l. and a t3 is considerably bigger.
ls motors are good up to 310 with goodtuner
