Hey firstly I'm gonna get some EL dials....has anyone got any places to get them...I saw some at Autoshop.com.au for about 250..they looked good.

But more importantly I have just replaced my K&N pod filter with a ram-pod filter from Unifilter...cos they rock. I have this plastic duct that sits above the radiator to get some air into the boxed area but I wanna run a pipe form the grill somewhere to get cold air in. Problem is...I can't find a good spot to do it cos in that part of the bar its all sealed off and full...what has every1 else done for theior CAI setups??

Thanks

Chris.

when i put my FMIC on i ran some pipeing through where the old bottom pip was (now on opposing side of engine bay) it pops up riht under the pod, very little modification/effort required

yeah I would assume so...perfect spot...but cos I have a 34gtt side mount one I have no space...maybe a FMIC is on the cards :)

FMIC kits are so cheap it's a crime not to get one. Even 34 IC is a joke so get rid of it before you chase power and bust an engine Chris.

GTT cooler isn't thatbad?? :)

Did alright for me, plenty of others too. Plus if Chris isn't chasing crazy power figures at the moment, why spend the $500 or so for a kit??

ta razor...FTO brothers stick together hey :)

but I think the FMIC was on the cards regardless so guys don't stress....it wojld set me up nice for a wicked CAI...now the only thing is which FMIC is ok for the money???

and thx for the EL dial PM razor...I'm keen not to get the normal white dials like in my FTO...although my FTO dials looks pretty aswome...I have a aliminum back plate and not looking for AL rings for the dials...can't find them yet.

Not tasking a shot Razor but even a modest increase in boost can result in massive post IC temps. Most never bother to take the measurements.

Consider I measured post IC temps of in excess of 60 deg on a 27 deg day. This was with just 13psi. I then measured with the water spray on getting 37-42 deg. Improvement, but not enough and I discarded water spray due to space and inconvenience. I also cracked 2 pistons playing tag with a Porka. I pulled in close behind him (about 2m) and even with the water spray got detonation on full throttle because it lost sufficient airflow to cool the charge. Unfortunately at the time I didn't have the water injection setup.

I then installed a Hybrid 800mm cooler and with 14psi (and 220rwkw which I don't even remotely consider crazy power but sufficient for street) I was getting post temps of 31 deg on a 30 deg day. At under 60kmh it would gently rise to 36 but as soon as speed increased it would drop quickly. This is without any water spray or injection.

So a quick percentage calc of volume and mass of the 34 item would reveal an efficiency increase of SFA, whereas a small 600mm Hybrid or copy would gain size of over 400% compared to the 34 item and should be as efficient as the 800HP I run since it won't be pushing massive power. The 600 would fit fine but the 800 needs some trimming behind the standard bar and at $650 delivered complete with piping and brackets is a bargain http://cgi.ebay.com.au/HYBRID-INTERCOOLER-...1QQcmdZViewItem

considering I paid 700 for mine 3 years ago with just the IC then had to fabricate piping.

Besides, Chris is a good bloke and I don't want to read of him busting an engine when he gets the urge for some go when some crook tuner says "she'll be right mate. We'll keep it a safe tune!" with no idea of the temps created, so on a hot day it makes that innocuous little "tink tink"sound and a month later is blowing the dipstick out.

My attitude now is fix it before it's a problem, having now busted the engine in the GTS25t track car 3 times (last was one of the twin turbs shattered). Fortunately I do my own work so it's parts and machining.

RB25's are tough enough for decent power (Inasnt has 320rwkw on the stock bottom end) but very susceptible to detonation so just don't risk it.

      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.
