Another quick question people how far could I push my car once on the rollers a quick spec of the car is.

sti8 bottom end refreshed,v4 sti heads refreshed, ported and polished,cosworth multi layer gasket,arp head studs,inlet spacers,with raised inlet,new cambelt and tensioners ect,
owen delevopments gt3076r turbo
zen performance ppg 5 speed gearbox
helix clutch rated to 550/550
sytech fuel pump
770cc injectors
simtek ecu
gt spec headers and up-pipe
New age coil packs
Fmic
The car is currently live mapped by jgm at 1.6 bar but I'm looking for more
But what sort of power could I push the car to,I only take the car out rarely maybe once a week if that so its not my everyday car but rough idea on figure would be great'

Also lateral took my injectors and done them so believe they can handle quite a bit as well

From what you have said the bottom end is rebuilt stock subaru.
I have it on good authority (from Zen actually) that STi8 rods are good for around 380/400 ft/lbs. You may get away with more as did I, but the question is for how long.
How brave are you feeling?

It's already running more than 380 Simon said was in 4s and it's been absolutely fine no issues what so ever

380 what though? bhp or ft/lbs?
I'm running 430/385 on V Power on a standard STI8 bottom end, and have done for the last 18 months thus far with no ill effects, but I change the oil regularly.
Simon (JGM) and I often talked about this before his sad departure, and the indication I always got was that he felt the standard block was capable of taking circa 450 or even a little more.
I know The Gimp on here ran his bug STI on meth frequently (482bhp) on standard internals but for more standard internals figures see the thread here.

I'd say you're more likely to start shredding your PPG gear set before you do the engine if you're still on a 5 speed, unless all of the gears are uprated?
A mate had a PPG with standard 5th and destroyed it and he was only on a 20g and 400bhp!

Very similar to my own stock engine, I ran 435/420 and launched it hard plenty of times. I'm not suggesting it can't be done, but there has to be a limit, and the nearer you get to the limit the more likely you are to find it.

The gears are all uprated the box was rated to 550/550
I was told that these engine could manage 500bhp don't know how true that was
But I do look after the engine and regular oil changes but I understand a lot of people have diffrent figure as to what they can run I do launch it but very rarely it's normally just accelerating while driving along, reason I asked is my car is running 1.6 bar on a gt3076
And my friends evo is running 550bhp we had a little play and although he beat me it wasn't buy a lot and he is also running same turbo with 1.8bar so I'm after a remap and more boost but only if it could handle it
