The best use you could get out of n20 with your setup would be spraying the intercooler. NX has a nice intercooler kit! See Link---------------------------

I know a guy that has a 03 SS with a Whipple,cam, all the other bolt-ons and he runs a wet kit with normal mounting(tapped in the intake tube close to the tb). He sprays 75 shot with no issues but a 100 wouldnt hurt.

 

If you dont do the pushrod and valvespring swap before you start shifting at 6500 your next post will be "where can I find a new motor for cheap". Stock pushrods are weak and start bending at 6200 the stock springs arent strong enough to keep pushing the pushrod back down over about 6300 or so. Get some comp 918 springs and a good set of hardened pushrods.

 

thanks guys i got the pushrods and springs already

 

He is on his second motor already! He experiments with so much ****(well his mechanic does)Only if he would be around here more often. He has the pocketbook and time for it.

 

Oh and he should be on his way back from the dyno and he put out some pretty good numbers! I will let him post it up!
