Justin ,
With forgies you can run 1.2 -1.3 with your 2530 's , if you are only after 1 bar you could use smaller turbos , 550 injectors are plenty for 1.3 bar boost , nismo or z32 airflow meters will be nice .poncams will be good to give you a bit more mid to top .
As for spending the piston rod money on brakes , yea i would too but the forged pistons are not much more than stockers form nissan , maybe 100 - 200 extra . For track work you most definantly need sump baffles and maybe a bigger sump an oil restrictor would be a good idea too . I wouldnt pull the engine down and put back the same pistons , bearings just to save $1500 now and spend $5000 later to pull it down again .
I have arias 87 mm pistons in mine n1 turbos ( about the size of 2530 's ) and i run 1.2 bar boost on stock rods , stock cooler ( r33 gtr) , stock injectors ( on the limit ) , stock airflow meters ( on the limit ) . I have power f/c and full exhaust ( 3") , stock airbox , stock cams and camgears . I had a couple of runs @wsid 11.7 @121 mph ,you could easyly do better with the above mods as my car is heavier ( r33) .
