be best to keep an eye on the fueling side as well so get yourself a decent fuel pump and injectors.
my 34 has the mods listed below in my sig my im maxing out my stock injectros and it pings at high boost so upgrading them next week to 480cc. better to be safe then sorry mate.
save up a little more dosh and get it done properly. get yourself a highflow fuel pump and decent injectors. fuel pumps are not that pricey its the injectors that are the killer, but its better to have everything and take it and et it all tuned at once as you will be saving on getting the injectors tuned again.
if your interested in injectros check out power flow injections here in melbourne. they quoted me $840 for 480cc injectors for my 34 http://www.powerflowinjection.com/ and so far they have been the cheapest.
so ye get you pump and injectors first before you try and tune it for high boost or you will end up spending more money on a rebuild.
or if you really really really wanna get it put on asap put it all in but tune it to a safe boost so around 200rwkw till you can afford to upgrade the injectors and pump
