Air flow meter. You will require 1 when aiming for above 220rwkw using a nistune or any air flow meter ecu. Google would have yielded the same sort of answer. There is so much info online about skylines. You should spend a bit of time researching and you'll get an idea of what needs to be done. Try and concentrate on the more current sort of info.

Best to decide where you are going to get it tuned and what you are going to be doing to the car before you buy an ECU as this will decide what ECU you should be getting. No point getting it now and finding that you need something different later on.

What Bosch injectors should I get

Decide on your power goal, the turbo required and then work back from there. Scotty may be able to supply injectors that will work with your existing rail. Don't buy anything until you know what it does and why you need it.

I would just save up for a while until you have a decent budget to spend and are able do get all the mods at once. In the meantime you can get a better understanding of what parts you want by reading up and asking the forum.

You've got all the basic mods and should just enjoy the car for what it is in the meantime. Im guessing you recently got it?

Enjoy it as is until you're willing to drop 5k on it to piss off the AFC and go ECU + turbo + inj + fuel rail/pressure reg and hopefully some change left over for a tune. Just do it all at once so you don't need to keep retuning it.

GCGs TD06 for the rb25 is good, bolts on to low mount manifold, etc

The 25 aren't like the old Nissan fuel rails. The standard 25 reg and rail can do 300+kw fine.

Afc is a good base to realize you need a proper ecu. They will knock off sbout 2 seconds 0-100. But that's about it. It's all the power at low tp that you want in a street car.

      As I've said elsewhere, I am using the stock intercooler piping path in the engine bay, and a return flow cooler, and making ~250 rwkW (without any effort put into trying to turn it up past there just yet) and expect to be able to make some more, and frankly, I would be perfectly happy with 260-270rwKW. This is peak road Skyline usability territory. You go past there and, sure, the car will snap necks more when it's on boost, but it will also break shit all the time, cost a (even larger) fortune in tyres, etc etc. Anyway, I also do not like the over-the-fan pipe path, and you don't have to do it.

      I see, honestly I’m not too fussed about the looks. The only reason to go plenum is to make the piping easier instead of the classic over the rad etc.

      Not easy to quantify wrt something like how many fractions of a second slower it would be over 0-100. But given that a 250-300rwkW car is able to do that launch sprint in 5-6 sec (and faster with appropriate tyres, and surface)..... giving up as much as a second would feel like torture. A ~450HP capable turbo is not going to make lots of boost in the 2000-3000 rpm range. So, whilst with some boost on hand it will be faster accelerating in that rev range than your engine currently is NA, it will not feel like a fast car until the boost is solidly in. You know what your car feels like right now when you open it up at 2000rpm. if you've ever been in an actual fast car, you will appreciate that the NARB25 is.... not exciting. Well, add some boost and it will be better. But shorten the intake runners and it might not be better at all. It might come out better, but it could end up feeling the same. For me, it's not the 0-X km/h sprints that matter. It is easy to fry the tyres with anything over 200 rwkW. You can't use all the power available in 1st and 2nd anyway, you have to modulate the throttle. What matters is how the car reacts when you're driving in traffic in 4th or 5th and have maybe 2000 rpm on board, and you want/need to add some speed quickly, and don't have time for the downshift. It won't make boost, it will be all NA (at the speeds we're talking about - remember how fast you're going at 2000 in 4th! and don't plan on breaking the limit by too much.) So giving away NA torque is not what I would consider practical for a street car. And retaining that NA torque builds boost faster which makes the car faster. The flashy plenum is not actually better, unless you're looking at a track car where you can keep it on the boil all the time.

      So how much difference does it make you think? Like 1 second in the 0-100?  I was have smaller turbo so hopefully that spools quick GTX2871.  currently it’s NA so you can imagine pretty slow, but I do want fast accusation a little as there’s not many places I’ll be driving where I go over 80 even near me. So 0-60 and 0-80 targets
