There is nothing wrong with 400rwkw....well unless you want more :D

Why not try the T517Z? I had them on my old setup and was able to put out 422rwkw on Willallracing dyno. The setup was a fun and reliable package for drag/circuit for 2 years aldready.

I upgraded the engine and maxed out these turbo with my current setup. I am looking at getting the T618Z's. I will use the T517Z for one more track day and will more than likely replace them with their larger bros. Does anyone have a pair of T618Z that they want to swap for a pair of T517Z? GTR747, if you are keen on these turbo or my complete old setup let me know. I changed the engine because the cam seals were old and a bit leaky but other than that the engine was still strong ;) I still have the power fc map for this setup. All you need to do is recondition the head, replace the rings, get a pair of manifold and you will have a reliable setup. My car and the spare RB26 are in SA atm too ;)

BTW sorry to go off topic but just want to help ;)

Thanks guys for all your help - im going with the GT-SS kit poss from nengun. Does anyone know if i'll be hit with any import tax's or anything? I have done some research and so far its been a mixed bag of answers.

anything over $1000 will attract duty.

Customs aren't silly.

They know all the people sending stuff in from JPN, so you'll be lucky if you get around it for turbos

come on, dont let them change your goal

you've gone down from 400 to 300 :D

go HKS 2530's, has both response and top end power

there's always room to improve your kw down the track, whereas with GT-SS, you won't improve much more than 330rwkw

what he said...2530's need 2bar of boost to do 400AWKW so its really stretching them too. GT-RS turbo's are the king of bolt on turbo's...currently powering the fastest bolt on turbo GTR on the planet.

save yourself some headaches, heartache's and lots of time and stress. Sell all the gear you have and buy our car...simple 500kw all day every day at a lowly 25psi.

Funny Funny lol but its true fastest bolt GTR on the planet

Im not saying i'll get around it, just how much duty it will attract roughly :rolleyes:

wow I never knew the 517z were capable of that much power...at what boost ? I always thought for those sort of numbers a 518Z was required....awesome result

hmmmmmmmmmm....a gift ay, :(

I didn't think they T517Z's were capable of that much power either !!!! :P

if your interested in buying from japan can i suggest emailing Streeter (he normally trades on ns.com) far far more reliable and cheaper then neugun. his email address is [email protected]

awesome reputation also so have no fear ordering from him

+1

best and cheapest way to gets stuff from from yahoo auctions, with the least hassles, even if you speak japanese :)

Remember whith trust t517z you need trust dumps becuase the internal wastegate is on the opposite side to garret trubo, so you need dump pipes to suit..

9krpm, your turbo's are still T517z just with a 10cm housing, they also come in a 8cm housing, much like you can get say a garrett 3071r in a .64, .81, .96 housings ect

wow I am really impressed by these T517Z's....Anybody else got any experience with them ? or maybe with the 518Z ? They seem to be a fair bit cheaper than equivalent HKS and yet perform every bit as good and maybe better..But last I heard was they dont come with water cooling...is this correct ? As a circuit/Street car oil coolers would then be even more critical...I am assuming

I would love to hear more about the T518Z too. I have a Greddy oil cooler kit and the oil temp has been fine at QR raceway. I only overheated once at Mallala but that was possibly from air in my coolant system.

Thanks for the info Daynamix;) I thought they are T5178Z all along :)

How is this differ from a T618Z and what would I expect with the larger turbo?

BTW the previous power was achieved with 18psi.

Some people call them either T5178z ot a T51710z, the last numbers which are 8 and 10 on both the names i mentioned refer to what size housing they are, eg T5178z would have the 8cm housing, and 10 would be the 10cm housing.. The differences between the T517z and the T618z would be like the difference between HKS GT-SS and GT-RS turbos.. T618z would be to big for the rb26, as they're the biggest low mounts trust make and would be suitable for a 2.8 stroker, just keep you current one's, they're a great bit of gear, i'm tossing up weather to run them on my next gt-r..

URAS will be able to give you some more info on these turbo's as he's built an rb26 s13 with these turbo's for driftcat..

Cheers.

Thanks Dyn. I bought a slightly stroked engine from Willallracing and have maxed out the T517Z. They currently have awesome midrange but are choking my top end. I can't produce any more top end power with them compare to the 2.6L. My tuner is tweaking it atm and I will see how it perform at the track.....but I think I will go bigger eventually :)

Customs are silly and there is no duty on turbo's GST yes Duty no definitely not.

They tried to slug me duty and as I know people in the import export trade i asked they they knew straight away

Get a good customs broker and they will tell you the same

cant get around GST though

    • 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.  
    • For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!
    • Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛
