300whp is doable with good tuning. Get a thicker head gasket to lower the compression a little if you can.

Do you have an intercooler? Alcohol/water injection can also help you get more reliable horsepower. 300 whp seems like it might be close to the edge without either of the above.
Also (scB20teg) who would you recommend for the tuning in the Portland area?

b18c with stock internals about 190psi if the motor's in good shape...

but seriously like the others said ~300whp should be relatively safe (and about the limit of those injectors) with a gt28rs or a smaller t3/t4... good luck

Yeah like dtated above go with a semi smaller turbo so u can use it across the whole powerband. Gt28 is a good choice the response will be nice and it will pull alltheway through the topend
