Thought it would be useful to share my turbo upgrade as i know many people are looking for a reasonable budget turbo upgrade.
After searching the forums constantly i noticed the gt3076r was probably going to be the best option for me. The hks range was just to expensive and the high flows dont offer enough power.
Thankfully people like Cubes, Lithium, Al and The Mafia had posted up there results and problems so most of their issues were avoided.

i think that is all
I have attached two different dynos. One was from December last year where you can see there was an issue with lag (this was caused by a faulty 7psi actuator). Unfortunately as the workshop closed the next day i had to drive it around for the next month as they only just re opened for tuning. I was stuck wondering whether this was just the way the car was going to be as many workshop said it was normal, (bullshit).
After speaking to cubes, lithium and discopatoe and showing them the dyno they all agreed it wasnt normal and to look at putting a larger psi actuator on there as they had experienced similar issue with lower rated actuator, thansk for the help much appreciated. Cheers to dangerman too. The Mafia for not bothering to respond to any of my query's.
So yesterday i had them put on a 18psi garrett acuator and problem solved, full boost by 3900 rpm. Note i have stock manifold, stock cams and it is rb25. The car was getting one ping of 80 so the tuner took out heaps of timing and managed to get it safe. Never goes over 10 knock on the road. As you can see 271.8rwkw is not huge but it was the power i was chasing as the engine is stock and i need it to be realiable. Also you can see the dip in power from 6500rpm onwards probably due to over heating because of faster boost. It had also done about 10 power runs so it was pretty hot. This was done on a W.A dyno so there MAYBE a lower figure compared to the eastern states. I am sure a set of cams, maybe a new manifold and i could see higher figures but at this stage i am happy with where it is an achieved my desired result.
The turbo sounds awesome just like a jet.
Must say cheers to hyperdrive also for putting up with my constant phone calls. Andrew your a champ.
