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.

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
