i dont know of anyone making more than 350kw using 2530s on pulp. so i guess the answer is no

I have often wondered about that as well. I have seen a single 2530 make 240 rwkw on an RB25DET. Now I know there are some differences between an RB25 2530 and an RB26 2530, but it isn't 70 rwkw worth. HKS rate the RB26 2530 at 310 bhp, so the pair should make 620 bhp, that's 460 kw. Plus other HKS turbo seem a little underrated, I think HKS quote 10% in most cases when pushed. I have never seen a GTR loose more than 60 rwkw (and 85 awkw), so I can't work out why a pair of 2530's wouldn't make ~400 rwkw. So I can only put it down to other factors, like tuning and support stuff.

There a couple of guys I have been working with that have 2530's and they are doing all the stuff that I would suggest is necessary to get 400 rwkw. So time will tell if it is possible. :cheers:

Ben from racepace told me there was a car there with 2530's pushing 400@wheels, most people who are running 320-350 aren't pushing the turbos for all they are worth.

Emre: i thought you were running 2530's and making around 400rwkw?

400rwkw from 2530s is a big ask on pump fuel.

I had a figure of 400rwkw+ on decent fuel, but obviously it's not my daily tune.

As mentioned, there need to be a lot of support modifications in place to run that sort of power daily, reliably.

For the record, i still have the stock intercooler, factory intake, internals, etc.

Holy Jesus... Look at the size of that radiator!!!! I feel so.................. inadequate :Oops: :)

Very nice welding on that intake pipe :D

Is that oil catch can vented at all? What's with the catch can between the rocker covers, and the secondary one with the washer bottle?

the large catch tank vents to the atmosphere.

dont think the one on the rocker covers does much at all, except look pretty

i did a nice job on the welding huh..not.thats bens fabricators handy work.

Hardcore! But where do you fit the twin 18" subs bro?? :confused: ;)

Emre: Engine is all bolted together, in the car and started up with standard injectors, old HKS F-ConV and standard AFMs.... Runs beautifully with zero leaks :) Will be calling the tuner tomorrow morning at 8am and see when we can slot her in for a run-in tune with the PowerFC Pro and then I'll start pounding out the kms as quickly as possible so we can get her back on the dyno and do some proper tuning :D:);)

I'm excited! :D

      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.
