VQ37VHR + Mods + 150shot = 450whp

Its not a MUST to tune but its good for the longevity of your motor. Nitrous kits are mostly universal in the sense that all the solinoids are pretty much the same...

The only thing you change for the shot size is the pill which is located in the sprayer you put into your intakes.... im sure you could use the HR kit as both have dual intakes and you would need 4 solinoids to do the job.... 2 fuel and 2 nitrous.

As far as tuning, its great to know what your A/F is so you can adjust to make sure you arent leaning out mid run.... but if you want to do it the cheap way you could just run a wideband to get your A/F reading then either choose bigger or smaller fuel pills for the fuel shot you are mixing into the intakes with the Nitrous.

I wouldnt do 150 shot because then you are in the territory of small blocks that have more displacement and can spread the mixture around to more cylinders. I would actually not recommend going over 100... I had an 85 shot on my 350z and it was more then enough.....
