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.

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
