For around 300-320awkw what size interooler would be best suitable for a rb26? I understand some people say that the stock cooler is good enough but I also would like to know what else could do a better job? Looking at running aroind 1.2bar boost. Is a 600x300x85 trust cooler a good size for the power level? And I have used the search button and would like more advice :/

Your spot on, the factory intercooler is ample for your application.

If you did choose to upgrade, changing to the Trust cooler you mentioned above would be a waste as it isnt much larger than standard.

HKS and ARC both make excellent bolt on upgrades for GTR - ARC is about the best you can buy and would be the way to go if your budget allows it.

I've got a PWR cooler and have similar power figures to you and have no issues with it. Quality is the best you could ask for. Not sure how much bigger it is than stock, I never seen a stock cooler ;)

ARC, end of story. You can't buy a better performing cooler period.

I went from Trust to ARC of the same size and the ARC just romps away in every way. 600x300x70 380rwkw gt2530's.

From the knife edged inlet channels to the flow through design to aid radiator cooling... My car overheated before...not now. I also picked up 300rpm less lag, bolt on.

Thanks fellas,

Its just that the guys at CRD reckon I will need a intercooler soon. How much are the ARC coolers? I had a look on nengun they didnt seem to have any for GTR32's

not so sure it would perform worse. ARE are one of the best cores around, and they fab very nice end tanks. PWR and plazmaman also make very nice gear of the aussie made stuff.

an ARC core for your 32 should be around the $1800 mark delivered.

why would you pay ARC money for less performance......

i'd like to see a comparison of the so called 'high flowing' japanese coolers.

like i said - i would rather support the guys in QLD instead of a massive company in Japan, if it does the same or better job.

but hey, spend your money how you like...

Granted the ARC is of excellent construction but, so is the ARE. I am not privy to any back to back testing of ARC and ARE so I can't comment but, if you have no data, neither can you.

ARE have the plus that they don't have a one size fits all mentality that afflicts the jap brands.

ARE do a great deal of on-going flow bench research to get the most from the end tank design.

ARC are offering an off the shelf 'bolt on' , it has excellent build and design. The cons are limited selection of core size and end tank config. You end up with some compromises and unless you happen to fluke it with your setup it's unlikely you hit the sweet spot for overall design efficiency. You get a good improvement of course.

ARE can undertake a custom build around airflow requirements based on hitting an 'average horsepower' aiflow target. They have some tricks in endtank design they have developed to increase flow they can throw in too. Overall you get something 'aimed' at your specific application.

if your stocker is stuffed, just jap do a 100mm upgrade "bolt on" for $300 or so, they have gtr style end tanks which are quite good.

I have tried one of these, the tube and fin design looks ok however the inlet and oulets are the wrong size(3") instead of metric...

granted, I don't have back to back ARE to ARC, however I do have Trust to ARC(of the same size core). The design of the ARC core will flow better than an ARE or any other brand I have seen of the same size core IMHO...but hey like what has be defensively stated I can't prove that. All I have gone off is the experience I have had and the design of the Patented ARC core's. Best go do the relative web site and research for yourself. For the record ARC offer full customs configurations....you have obviously not done your own research.....

As for fluking my setup style......lol, no fluke...... thats the reason people buy ARC the are tried and proven...

I feel what it comes down to....petty bickering aside.... ARE offer a product that is local and cheaper, which I believe to be similar quality to some Jap brands. ARC is definately more expensive and harder to get. In my history I have owned 36 cars most being turbo charged and intercooled....in my experience I have personally found ARC to rival all others.

      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.
