Default Some Nitrous Help, Any experinced people would be nice.

Hi guys, I'm not new here, just a new named, but i had a few questions
My plans within the next week or so, is to get the car gassed..
I've done the whole Frogger threw the intake thing but now i'm ready to move on..

I have a Direct Port system setup right now, tapped under the manifold(sneaky ) i have pics which i will post up in a few hours
I have sprayed a 50-75 shot on this car
My setup consist of the following

Its a 97 USDM Spec Type-r block(b18c5)(Stock internals)
The head is a jdm 1995 B18c, it has a full crower race valvetrain with their new ti-retainers, Dual race springs, etc etc.., Ferrea SS high compression valves, crane rocker arms, skunk2 stage 2 cams, buddy club cam gears(+2 exhaust, +1 intake)
sparks racing header,skunk2 intake manifold with hondata gasket, SRI, Tsudo Extreme N1 2.5 catback, custom made flexpipe(2.5 str8 threw)
NGK plugs/wires i'm running the BLK7's right now. Car is sick all motor wise, pulls all the way to 9300ish rpms, vtecxover is at like 5600
my question is this..
Whats the calulations of the jets i'll need to equal a good shot direct port wise..when i say measurements i mean the .021 jets?? i'm looking to do anything between a 80-100 shot.. I'm sure this motor can take it, cause its been maintained and the last time i pulled the head off which was about 2 months ago, the pistons were crystal clear, hones and cross hatching from the factory were still visable the car pulls sick, doesn't smoke or anything, gets great gass milage, its tuned by myself on crome pro, So my question is what do you recommend, i'm assuming i'm 210+whp with this setup, My CR is 11.6+, and i'm holding 260psi in each cyldiner on a Comp test... Any info would be nice.. so far, its a str8 dry shot, i have it mounted and everything but i just wanna get some good results..looking to break at least 300whp on this motor.
For every 50hp its retard 2 degress timing correct?? Lemme know guys.

This is the best nitrous calculator I have found.

As far as the setup though, I have to ask why dry? You will get more consistancy and safety out of a wet kit by far.

And yes, two degrees for every 50 hp and for the love of god, run a window switch if you don't have one. The only time I have ever hurt a motor on nitrous was when I went cheap and didn't use one and I have sprayed a lot of cars.
