ok, i'm getting sick of reading the "lets pile shit on WA cars". I for one can tell you that i'm on stock injectors, and at 12psi pushing 220rwkw or thereabouts confirmed through numerous runs and several dynos. At that power level, my injectors are at something ridiculous like 95% even with a rising rate fuel regulator and a 450HP pump. Every time I wind the boost to this level, i get nearly exactly the same result on my PFC and dyno printouts. Not all WA cars have magic power figures from special dyno's with miracle stock fuel systems. I have a receipt from my tuner (Hyperdrive :rofl: ) after my powerFC tune that says "Recommend bigger injectors".

Get over it already.

220rwkw eh, my car was starting to lean out at 198rwkw but that was with stock injectors and ecu (a powerfc might fix this) and a Bosch 040. It might be that my injectors are running out of puff, not a fuel issue.

highest power figure Ive made on stock injectors is 248kw on a dyno dynamics dyno at Daltons automotive (not in shoot out mode). couldnt tell you what the cycle is, the microtech i'm running doesnt read in percentages just milliseconds. also running a malpassi adjustable rising rate fuel reg and bigger fuel pump.

I know this kind of power isnt safe for stock injectors....cant imagine the spray pattern being very good, which equils damage.

Nismo injectors arrived a few days ago, so.....no longer a consideration.

I always had the intention that once I achieved beyond 200-210kW i'd replace the stock injectors as after this point there reliabitity is questionable. Just took me about 6 months cauz the damn things are so expensive.

If you are nearing 100% just move to WA and the problem is magically solved :)

;):):rofl:

Who needs injector to spray just leave them set open :wassup:

I wouldn't risk using standard injector's over 200rwkw's for safety reason's. I'd get a set of Nismo 740's if you looking at upgrading the turbo later, or 550cc should fine for 300rwkw's.

Fuel pump should be first on the list it'll max before injector's.

im going to call bullshit

what a/fs and how laggy was it

i couldnt see the stock ecu being awesome with 260rwkw

i hit 92% injector duty with 172rwkw and your saying is getting 100rkw more ?

sounds nice and safe

      This is a story of my life things, I learned eventually (thanks to someone calling me out) that my enthusiasm for discussing and sharing ideas that it came across as arrogance and I'm like... WTF?!    One thing I'm pretty sure I justifiably pride myself on is knowing that everyone will have things they can teach you, and you're always going to find out that something you think you know turns out wrong - you just don't know what it is until you get there.   Just the bursting enthusiasm that comes with ADHD when you hit something that gives you dopamine dumps can come across like you think everyone else is wrong or don't matter. But yeah, I'm a software engineer by trade and also do tuning in weekends and 100% have long had a reputation for  quickly making connections when resolving problems or forming solutions that I've sometimes had to take people form a long walk from start to end to explain how I ended up where I did when it's seemed "too simple" when I've stated my initial case, and had the "WTF" type reaction when they've realised how much was actually considered haha.   My reward is that I get all the curly problems thrown at me.

      Wives never seem to find things funny. Especially when they're trying to sleep, and you've found the new funniest thing ever. I've never seen someone be able to get try and be cranky with me, while they're holding back fits of laughter... 😛   Also, I tell mine it's payback anyway. She has BiPolar. So the household can get quite emotionally wild at times 😛

      WA PITS: Am I screwed?

      By Butters · Posted

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .

      WA PITS: Am I screwed?

      By Degzy · Posted

      Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?
