You should be able to go high 11's on a TA33 with an intercooler. I think I'd want a bit more injector though. If you're going to up the injector, you can up the turbo a bit. But then you may want to consider upping the converter as well. Get the TA33 rebuilt with TA60 internals, give it some 009's, and a mild converter in the 2800-3000 range and you'll go mid-low 11's maxed out.
