Hi all,

Just after a bit of advice, The car is a GTR R33 Skyline.

The items that are fitted is

N1 Turbos

exhaust - Just fap front pipe, highflow metal cat and cat back Kakimoto Regu 06&R.

Blitz SUS Pods

Trust FMIC

Have bought ready to install....

Greddy profec 2

Tomei Cam gears...

and

Power FC and controller

Standered fuel pump, injectors etc etc

Should i change the fuel pump? or injectors? Will the stock GTR items be ok? If need to be changed what would surfice?

Should i look at adding anything??? I want to do as much as i can before the tune so i know it'll all be right.

Just wondering what COULD be expected from this set up??

Thanks

You need both before installing the PowerFC or you'll be wasting your time and money tuning it. You'll max out the injectors before making any meaningful power and the workshop will most likely tell you what everyones told you already.

upgrade your fuel system....

Injectors and fuel pump will go to about 270kw - people say 300kw but it never makes it to there as the are old and tired

I would personally go some bigger injectors and also a new fuel pump - NISMO/TOMEI etc

You've come this far so you might as well put everything on at once and get it all tuned together otherwise you would be just wasting money going back later for more boost + injectors & fuel pump

Yes - Although the 040 might require you to modify the cradle to make it fit - had to cut the bottom of the cradle off in my GTST

TOMEI pumps go in way easier - use the stock fittings/mountings etc and come with new seal and shit

Yes - injectors are piss easy in GTR

there is a DIY somewhere as well

Also with the fuel pumps, all the nismo 276L/H, HKS 280L/H Tomei etc etc all around the same price etc So they all around the same??? or are any better than others??

you might get away with one of those up 350rwkw maybe..yeah yeah I know heaps of ppl are making that on standard pumps blah blah blah...its about how much power you want know and in the end run, sure you can use it as a lift pump in the next upgrade but then that means another tune and more $$$ wasted...just do it rite the first time and be done with it, run new fuel lines like 3/8" lines again ppl say standard is fine but think 3/8" or 10mm is 20% bigger in size than standard...

At the moment greenline has a special on SARD injectors, so i was thinking some 700cc. Will they do the job?? As there the same price as the 660cc ones

Also with the fuel pumps, all the nismo 276L/H, HKS 280L/H Tomei etc etc all around the same price etc So they all around the same??? or are any better than others??

Nismo and HKS are better pumps than Tomei. A few ppl have said Tomei's lose voltage at high RPM and the engine leans out.

GET the pump and injectors. As soon as i cranked the boost (from stock to 12psi) the pump started to die.

Pump change is a DIY job, i'm not a mechanic and i got the old pump out easy. Injectors give the DIY sectin a read.

Get injectors that suit what you need from them. No use getting 1,000,000cc's when i.e. 660cc will suffice.

Don't put a junky Bosche 040 in your GTR if you want to make good decent power and reliably.

Get a Nismo 275lph @ 72psi pump. It will fit it like a glove and require no modifications. Oh, and you won't have pickup issues either.

      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.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
