Looks good. I'd say 300+ with ease but at what boost level (thats why I said a really reasonable #). Get the tune first to make sure shes running the way she should (you want as well) like you said. I would up grade the fuel system and clutch (didnt see it on there and for ones own sence of mind) so she wont give way during those track runs. Porting couldnt hurt but since shes still fresh I'd do all the above but then again I'm alittle power hungry. I'm sure somebody else will chime in that has a better idea than me. My .02

ACT extreme with the street disc is a great street/strip clutch.

First get a fuel pump and some injectors. Next get clutch and tune. You should be a tiny bit over 400 on pump gas. You may need to add an ignition amp too.
Suggestions on parts: Supra fuel pump, 850 and 1680 injectors, ACT extreme clutch. HKS twin power

if you don't already have the turbo, then i suggest sizing it better unless you plan to port the engine to support that turbo. a GT40R is a great unit, but stock ports are not going to do it justice and you will more than likely end up unhappy.

Yes, it's plenty of turbo. Just get all your supporting mods and get a compression check before you start really boosting it hard.

It doesn't hurt the motor at all. The stock ports are just to restrictive to get quick spool and high hp. Don't forget to upgrade the fuel pump too. You should be able to get 400hp on pump, maybe a little more with some good tuning.
