Nitrous is a great way to make power if you are willing to take the time to learn how to use it and spend time developing the system so it is safe and reliable. I have used it on several platforms, and will continue to.
Whether its its right for you or not is hard to say. Nitrous has a tendency to attract those looking for easy fixes for a problem when in fact it takes serious commitment, and has major consequences if you are careless. Another thing to consider if you plan to compete is now you have multiple power adders. That’s not allowed in some classes, or may put you in a class that is very hard to compete in.
The price tag you see will balloon significantly when you factor in all supporting work to make it safe and reliable. It’s still a very affordable power adder though.
If if it were me, I would continue refining what you have until it is working very well, and if you have the resources and desire to go much faster, consider it than.
i am not fussed about the class issue more the reliability one for example what would be the the reliable expectation of jetting 50hp or 100hp should i be concerned about my ring gaps not being setup for nos if they need to be or what do i get colder plugs.
Most turbo setups shut down the nitrous when at full boost. Is this your plan? If it is, you should be fine with current parts. Might need to go a tad colder on plugs.

That was not really the plan i was hoping to launch click second gear and push the go baby go button i thought a 75hp shot was realistic as i could just fatten up my fuels a little and throw a wet-shot onto it.as my timing is apparently already very conservative.

Do it! That's a very realistic shot. If you're adding nitrous for power, I'd go for a 100 shot out of the gate.
the advice i have recieved which is run a slightly larger fuel jet and pull a lot of timing and work my way up i wish i had a megaquirt or haltech but the aem i have is very basic so i have to be a little careful but at the moment im at 20-22 degrees at the moment and 12.8 fuels and 26 psi.and from what iam told thats conservative i will have the kit monday and i have started looking into a bottle heater and remote pressure gauge
Almost forgot one very important thing I learned the hard way. Nitrous is notorious for blowing the back cylinder on inline fours. If you have a single fogger and it’s very close to the throttle body, the back cylinder will ingest most of the nitrous. You need the fogger at least 9 inches upstream from the throttle body so the charge mixes properly with the incoming air.
I’ll never again run nitrous with a single fogger because of the mixing issues.

If I did a single fogger setup, it would be as far as possible away from the throttle body. In my case, I'd put it just after the exit on the intercooler.
Tyres are on 225/50/15 mickeys are a fair bit taller and seem a fair bit wider its a perfect fit. I still waiting on Nitrous kit they fucked up the order i am also going to order a bottle heater and a window switch and a purge kit as i want to do this properly.
Ok i have the kit i will start making the mounts for the boot and start looking into controllers.
I am going to the drags this Friday and see how much difference the tyres make then i will go again but with the bottle the only question i am hoping someone can answer i have a walbro 460 in-tank pump i wont be anywhere near its limit or my factor hard lines will i ?
OP is already around 400 whp, so on nitrous could be anywhere from 450 to 500. The curvy 5/16 fuel line from tank to fuel rail creates an awful lot of friction to keep up with the gaping hole feeding both injectors and fogger nozzles. Particularly when you factor in the sudden release of fuel and harder g force in drag race conditions.
