I don't think you'd see that big of a difference in 83mm gsr with nitrous any more than you would 81mm, without the accompanying stroke increase of LS/B20

As far as my current P73 piston build, you think a 440cc RC injector would be too much ? I figure this will give me room to grow into them when I start making more power, paired with the 255lph walbro pump.

I assume you tuned it with S300 also ?

I am using Apex'I Power FC V.2.0 standalone. I haven't used Hondata since 2004.

Here is the build. Still kickin' almost 10 years later.
