what parts would i have to change inside a n/a motor to make it turbo??? or would it be better to just get a rb30t instead cause i want to get some good power

The Only Difference On The Inside Is The Pistons, Hence The Compression Ratio, The Oil Pump Is A Little Larger On The Turbo Motor To Feed The Turbo, And The Cam Is Different, Thats It, If You Are Going For A Fairly High Power Vlt Then You Will Be Better Off With A Better Than Std Cam, And Some Forgies Dont Hurt, So Then The Only Thing You Will Want Is The Oil Pump. Same With The Bolt On Gear, More Hp, Less Std Gear .

If i were you this is me i would just get a Factory Turbo Motor and drop it in your Engine bay! Not only it's a Genuine Turbo Motor but less hassles to convert a N/A Motor to turbo.

spend out and get a RB25 head on it man abit more work but you can keep ur NA engine and with the head get perfect turbo compression ratio all you need is to run the R33 AFM and ECU or aftermarket ECU and get the oil and water lines taped presto get cooler and exhaust and so on so on really its an engine in car job i was told.
