Which Turbo Setup?

[Shazz]

After all sorts of issues with the new motor not making power it turns out the bearing on the front turbo has let go. The car is used as a weekend driver, and with the occasional track day etc, i would love to eventually do some hill climb events. The engine specs are below, however what im trying to decide is weather to rebuild my HKS GT-RS turbos go for maybe a set of -5 (2530 i think?) or go single setup like a T04Z etc....

Engine specs:

Eagle rods

cp pistons

greddy 264/9.1mm cams

greddy valve springs

external of motor:

HKS manifolds

HKS dump pies

HKS GT-RS turbos

Equal length stainless front pipe

titanium 3.5" exhaust

greddy intake kit

greddy suction kit

greddy intercooler

Sard fuel rail

1000cc injectors

surge tank and twin 044's

Aem ecu

removed air flow meters

I have been reading through topics and it just seems to make me more indecissive. The origional plan was to build a 600hp @ the wheels gtr with a stroked motor. I still plan on building the stroked motor however for the time being this is how it is setup. I cant see why i wont make 500-550 hp with this motor, if the right turbo's are matched. I know a lot of people are against -10 turbos, however i have not had the car runnnig for long enough to get a feel for them. i do realise they are laggy, and are going to shuffle. will -5s shuffle?

The ultimate question and im sure there wont be one difinitive answer rebuild, replace, or sell it all and go a single setup?

You can make between 400-450rwkw on -5s (with a decently built motor) and E85 - it's been tried and proven - plenty of info around.

Failing that if you want to go single - pages of info there as well.

Please take the time to use the search mate.
