Sorry to get off topic, but i need some adivce.

I am able to get a TRUST FMIC and piping straight from japan, at a cheaper price.

It is made for an R32 i have been told

I have an R32 Gts-t, with an R34 turbo running 10 and 13.6 psi, has a 2.5' full exhaust.

What size cooler should i get for best results? 600x300x70?

How much will this improve performance?

Cheers!

meshmesh...for what its worth i have driven a Rb25 with a 2530, PFc, and it had a 600 x 300 x 100 Trust tube & fin cooler, and the thing was still super responsive, it also had a Greddy plenum.

I cant see why this cooler (or similar dimensions) wouldnt be a good upgrade for a GTR with 300rwkws, as for new piping, the HKS/Trust piping kits looks the part, dont know if it really needs to be upgraded, i doubt its worth the money though.

Sorry meshmesh, I though I answered the question, let me be more specific

1. what size cooler?

600 X 300 X 115

2. brand? as each maker claims there name to fame eg: pressure drops, flows etc.

Greddy, tube and fin, they use cast end tanks with nice airlfow shape like the Standard GTR intercooler. Check around, the prices vary a lot, we buy from Nengun.

3. do i need new piping "?lbs pm @ ?litres of pipework"

No, standard GTR pipework is OK for your power target.

Hope that helps

Hi Flaps, a standard R33/R34 GTR intercooler would do the job for you. We see around 20 to 25 rwkw increase from using one on an R32 GTST RB20DET, if you maintain the same boost levels at the turbo ie; about 2 psi more at the plenum.

Hope that helps

Just while we are on GTR coolers, i have noticed that like my Type S cooler, the tubes used in the core are rather thin when compared to most other aftermarket cores i have seen... Hybrid, Plazmaman, Micks Metalcraft etc etc

A lot of ppl seem to ask about pressure drops, flow capability, affect on throttle response, but everyone seems to assume that as 'heat exchangers' they are all equal.

Is it just a case of give or take they are all equal, or is there somthing to Nissan and HKS using the tube thickness they do to ensure maximum heat transfer at a given power.

After all in order for heat exchangers to be effecient they need turbulent flow, not exactly desirable for good flow or low pressure drops...like all things in life its a compromise.

Force, I think the Nissan GTR coolers vary slightly depending on which model GTR they came from. Not absolutely certain, but I think R32 cores have one less tube than R33 and R34. Also core thickness changes very slightly (5mm?) as well.

For all practical purposes they are really all the same, if you are thinking of adapting one to another car it does not really matter which one you use.

I am about to take delivery of a '97 R33 GTR which is currently completely stock. I am wanting to do some work to bring horsepower up for weekend track work and have been trying to get as much info regards mods as possible before spending wads of money. Many threads mention going for "as big a FMIC as possible" in the early stages to avoid having to continually upgrade as HP increases. I am unsure at this point, but it would appear from this thread (and please correct me if I am wrong) that the standard R33 GTR intercooler is probably up to the task for most mods.

Hi maccattack,

I'll quote SydneyKid, "Before I can work out whats best I need to know your hp target"

I'm in a similar position at the moment, but as a guide, the SydneyKid flowbenched a stock gtr cooler & they are good for around 300kw at the wheels. Your next bet is the Greedy 600x300x115 using stock piping.

Hey Meshmesh.

Thanks for your comments.

At this point aims are for a staged (ie: bit by bit) increase up to around 300Kw at the wheels. All reading to date seems to imply that cool air equals power, therefore start with the intercooler. In QLD quite often on track temps run high 30 degrees to early 40's, so therefor it is going to be fairly important to keep it as cool as I can. By the sounds of things, the existing cooler isn't bad (in fact quite good), but would chasing 300rwkw (taking into account the ambient temperatures on track) warrant going to a bigger cooler??

Using stock turbos you'll be lucky to get 250-270~@wheels. If you decide on upgrading your turbos "N1, GT2530 etc", then you'll hit 300+

COOL AIR EQUALS POWER... That's interesting, I'm so inclined to go with a Water Injection set up see www.h2oinjection.com (Not the water spray over the intercooler - although this will also help) working something out with skylinegeoff when I get around to it. Even though everything I read seems positive, my tuner is against it full stop. :confused:

I would hazard a guess that if running on days of high temp the a water injection set up should help, the only thing that seems to be standard across the board is avoid running WI before the turbo "as this can damage the blades over time".. still looking into it anyhow.

If turbo upgrades (which no doubt in the future will occur) are required, would the standard GTR intercooler be up to the task based on the resultant heat increases or would I need to increase the intercooler size or increase it's cooling capacity with something like the water injection or intercooler sprayer??

Do not do this, the turbine blades will erode in a suprisingly short amount of time, if not disintegrate.

It would be like running a car with no air filter and pouring in dirt on purpose, straight into the compressor. When a turbine blade is running, it doesnt matter what hits it, dirt or water or whatever, the result would be the same. Not good.

      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.
