If that's all you want then best opton is to stick with either the stock CT26 and run more boost....they will handle 15psi no probs all all and so will your ECU. Should give you a big enough buzz.
If you want some headroom for more in the future then get the stock turbo rebuilt with 50 trim garrett comp wheel. If you et the exhaust manifold, turbine housing and dump pipe ceramic coated and have a decent full 2.5-3 inch exhaust, boost response will remain as good as stock or actually a shade better but with a much more solid mid range and top end punch.
The safe limit of the fuel pump and injectors is around 280hp although theoretically you should be able to push them to 320hp right on the limit.
Bill Keen at ATS in Adelaide is the CT26 guru and the man i would talk to about doing the work.
