before everyone asks me to do a search could they please read my post below because i need help with my decision

i currently have a r32 gtst with full exhaust, filter, fuel ump and have a hks gt2530 and FMIC on the way. after that ill get a chip

here are the options i have

1) get a nimso fuel pressure regulator for $200 and be happy with say around 210rwkw

2) get GTR injector $250, get them cleaned $150, then get a resister pack $100. all up thats around $500

3) if im going to spend $500 on GTR injectors i may as well get nismo 720cc injectos for $600 off a friiend

the questions is this. do u people think i should just get the nismo regulator and see if that will push up to 220rwkw? because if i decide to get the injectors for a few more KW its going to cost that extra $500 and im a cheap arse

Just check the impedance of those 720cc nismo's...you may find you need a resistor pack for them too.

p.s. lack of fuel is the main cause of engine damage/failure.....that is after lack of oil

the iibjectors may be 600cc or 720 but are the same impediance and are a direct bolt in ive been told. thats why i thinking about getting them over the GTR ones

and yes that is my main concern. i dont want to engine to be starved of fuel

I'd say go for injectors for sure

I had stock injectors making 200rwkw and it was dodgy at best

I have GTR injectors now, and at 205rwkw they are running at 70% duty, so the stockies where well past it

Some people reckon 220rwkw is possible out of stock injectors, but all dynos read differant

my 200rwkw stockin/inj was on a differant dyno to its current read out, so on the same dyno I reckon it would be 215+

It makes a extra 45rwkw midrange, as we could screw in heaps more timing and fuel with the safety of the bigger injectors

I'd go injectors for sure

am i missing something? (highly possible) you mentioned a chip but if you opt for bigger injectors you'll need a prog ecu or remapped stocker.

as you know that alone will give you a power increase. if you get a used pfc for $800 that's not much more than the cost of injectors and gives you much more flex. some people have had good results with increasing pressure - within reasonable LIMITS - as a 10% increase or thereabouts puts the pressure below the upper threshold stipulated by the manufacturer in most cases.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
