I rang them - It's like hype said :

Stage 1 - $2200

Stage 2 - $2400

Stage 1 for street use - more drivable

Stage 2 for strip use - less drivable (assuming this means more boost comes on later)

Both represent significant gains over standard - Not sure what 'significant' means.

Both sides of the turbo are highflowed using exisiting housings. Ceramic turbine chucked our and replaces with a better one - All bearings replaced.

Not sure, but I saw in another thread that a Hi Flow job coast $1300 - maybe that was just the compressor side ??

I spose when you are talking about a turbo - it's worth paying a bit more to get a professional job. Plus - it's still cheaper than a new/bigger turbo - Plus the look remains stock.

I think the other turbo for 1300 was a thrust bearing and GCG do ball bearing. It would be interesting to see peoples thoughts on which bearing to go for. If it is worth the cost. This could be for two reasons i.e. wear on the bearing, if this is a concern do thrust bearings wear out quicker and how long would they be expected to last ie 15psi. And in theory ball bearing should spool quicker all things equal however has anyone had any lag due to going thrust bearing conversion.

It all comes down to money and in this instance up to a $1000 more for the GCG ball bearing version.

For what its worth...

on most engines thrust bearings are fine if you dont mind the possibly slower boost response.

However i hear that RBs arent renowned for their high oil pressures, and when combined with a thrust bearing turbo running @/over 1 bar have been known to wear thrust bearings, internals pretty quickly.

The higher boost levels and lower than ideal oil pressure force the oil film to disperse allowing metal to metal fouling of the thrust bearing.

Anyway thats the advise ive been given and it seems sound enough from a logic point of view.

Anyone read the article? What did you think? I rang Kyp from ATP and he wouldnt tell me any specs however guaranteed 220rwkw with my setup. They had a car produce 238rwkw. Well priced under 2k including match porting exhaust. Still only bush style bearing.

Anyone had or heard of any experiences with these guys.

I picked up a second Hand HKS t04e for $400, and just need an external wastegate, even if it needs a reco that anly costs about 700. The manifold modification is not too hard if you have the right tools, I am macking a steel block that will get welded to the std manifold, and the gate and turbo will bolt to this. You could probably gat something similar made for about $400.

I rang the dude at Port Kembla. He reckons he can do a reco & small hi flow for $800 (keeping the ceramic turbine) But for $1200 he can do a much better job and replace the ceramic turbine.

Might be worth investigating a little more.....

Geez, Garret GTs even HKS turbo's (when got from Nengun) are about that price "NEW". I guess its cheap if a big part of the cost is labour to remove and fit the turbo. Otherwise I'd go buy a new one.

The GT25's are 'bolt on', will make more power and be more reliable.

      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.
