I don't know what the Wiseco's are rated at,
I'd look at them first since they're a great value for the $ if you are going +.030" or .045".

Other than that, and thinking towards a future of more nitros,
I'd go custom with some more meat added to the top and the ring lands dropped,
starting with talking to these guys:

most any good forged piston is fine for nitrous you just need to drill holes inside the top ring grove for porting the extra pressure any good machine shop can do that that what I had done to my piston and there trw 10.5.1

250 is the recommended top end for virtually all 4032 pistons. 2618 alloy with the correct machining done will handle almost any volume of nitrous. But 2618 requires a larger clearance than 4032 and pistons at that level are creeping into what I would call the consumable zone. But there is a lot to the discussion. Your best bet is to ask the piston mfg what they recommend.
