yeah, 226 pages later we have said plenty of times that the T3 internal gate kandos do not work. If you actually read the thread you will find results of ppl testing the iwg and that it sucked.

yes a 3071 is a good turbo, but just get a hypergear and save your money. Bolt with factory dump pattern.

an SS2 type B will be better than a 3071, based on specs.

this...

I have driven a 3071 Rb25 car (with a .86) and it was woeful to say the least and from what people say the .63 fails

admittedly i'm used to an HKS modified 3071 that is unbelevabley good.

IMHO go a smaller garret or ex gate

i just didn't feel the garrett 3071 was worth the money

I also think the cropped 3071 (HKS 2835) is an epic turbo for an RB. The delivery is brutal on an RB25, but I probably wouldnt go there on a 20. the bigger 60mm 3071 will be more responsive for the 20.

The Hyper Gear items are similar in spec to the garrett variants but Stao customizes the wheel sizes to be more application specific. The SS1PU and SS2 replace the 2871/GTRS and 3071 respectively, and is bolt on.

Mates, please advise: i have choice between Kando dynamics TD-06 20G and Hypergear 43 G. the cost of hypergear is bigger, but both of them are bolt on to the stock exhaust manifold.

could you tell me which turbo is better and why?

thanks

Hypergear is a bolton turbo, so it is far cheaper then Kando items counting installation costs. If you are comparing internal gate, stock manifold bolton performance its obvious that hypergear is a winner.Some of their latest billet turbos performed extremely well. They've released their billet version of TD06 SL2 20Gs that again appeared to be more responsive and punching out better no.s.

For a bolton turbo internally gated turbo for "Up to" 280rwkws I would definitly go for an hypergear item. Or if the decision is on a SL2 20G I would still go for a Hypergear's Billet 20G. for a 25G I probably go for a Kando item.

Put it this way, the kando internal won't work at all so you will need an external gate. By the time you pay 700 for a turbo and 400 for a gate, you are already nearing the cost of the HG. Then you still need to have your gate plumbed and dump pipe made which will cost over 500 easy.

you should make a responsive 260 on 98, 300 on E85.

Then you have the HG ss1pu. Complete bolt on, uses the factory dump pattern and all. no external gate, no dump pipes to be made. Just bolt on and make an intake pipe.

cost way less and still crack a responsive 250-270.

So had my rust bucket on the dyno the other night...

Old setup here: http://www.skylinesa...ost__p__6010134

Added ID1000s, billet comp wheel, poncams and re did all the pipe work in 2.5" stainless(was a mix of 2.25/2.5 before)

Tried more boost but it didn't really do much, perhaps a restriction somewhere (runs 2.5" cooler piping, 3" exhaust and stock throttle body) AFM was at max also.

Forgot to grab an overplayed map but if you put them side by side it looks pretty similar apart from the extra 30kw up top thanks to the cams(boost was almost the same). Most noticeable difference is how ridiculously smooth the thing cruises around with the ID1000's over the High-flows!

I love how these thing feel like your entering warp speed over 6000rpm lol, wants to keep rising even at redline.

Not sure what to make of the billet wheel though, perhaps the cams lost a little down low and the wheel brought it back up?? I think Simon will have to give one a shot so we get a genuine back to back.

Edited by battery

Thats on boost nice and early and making a healthy power figure battery :) I like your setup under the bonnet too. Neat and well presented.

Based on Stao's billet 20g results, I would say the billet 25g is also an improvement. I think all those parts come from the same supplier anyhow. So my logic is if they could improve the 20g im sure they also improved the 25g.

And if its warp speed at 6, you should rev it to 9 LOL!

Well you didn't exactly go backwards anywhere...

Hard to tell what made the gains, probably a mixture of both the cams, piping and billet front wheel.

Must be happy anyway, I'm guessing it still hauls ass!

No billet love for me, but I'm going to be selling my Green 32 very soon (if anyone is interested in buying PM me)

Edited by SimonR32

Yeh Trent seemed to think it would get to 380-390kw if we upped the rev limit, but im lazy and I'd prefer to not have to swap in another engine if the thing went bang..

LOL i can understand the logic, dont worry.

I wonder if theres a way you could shift the powerband to the left... I guess VCT would make that hard because you dont have as much control over the intake cam.

impressive result still , it knocks on the door of 200rwk at 3800rpm , why does it dip again for 100rpm?

I'd like to see an overlay. Might be wrong, but I couldn't see any significant differences at 4000, 5000, 6000, and 7000 rpm points although the shape of the curve between them may be slightly higher. I agree with Simon, it's obviously not gone backwards. But an overlay simply hightlights the advances.

The torque curve is showing a falling trend by 7000, and the bigger power number appears attributable more to a little kick in torque over the final 250rpm. Run under similar conditions with no other mechanical changes it would be hard to see the thing make the suggested power number simply through extra revs, but compromising your engine reliability would be a certainty at some point if you did.

All said, the result is certainly good, and dyno numbers can't be expected to convey the difference in feel as the engine runs through its speed and load ranges. Well done overall Battery, and I bet it does haul. Hope you intend tracking the car, not just dyno or 1/4 mile?

So pulled my TD06 of today..

Exhaust Side;

Exducer: 66mm

Inducer: 59mm

Running off this site; http://website.lineone.net/~jon_ed/Turbo_Table.htm.

Does it look like I have a TD06SH-20G (factory internally gated)

Bugger, that is the big bad boy rear turbine. So not the smaller turbine that most people run on a 2L or people here are using on their T67 etc.

From what I can see on the Kando website they only do a T25 8cm housing for that turbine. So you still need to do an adaptor for T25 to T3....then still running the biggest turbine you can run in the TD06 range.

May be best to give that turbo the flick to an RB25 owner who wants punchy 260-280rwkws that hangs in there nicely in the higher rpm

Bought myself a GTR, so I'm planning on going broke haha

Last weekend before I'm going to put it up for sale I've been playing at powercruise :)

Just to give people some idea how much abuse this consists of check this out

Peakvalues.jpg

2 bar and 8900rpm :) Both were spikes but it still loves it

As far as reliability goes it's been nearly 2 years and the car has not had a single breakage since I put the RB25DET and Kinugawa turbo on.

    • I like mine. Much better than stock. Like i said before the reverse/parking cameras look even worse than normal, still useable. When you buy one make sure it's the latest version. Heaps of cheap ones that run the old hardware and software. Got mine from AliExpress. Mine is quick no lag, boots up 1-2 sec. Menu is fast. Netflix is fine and so is YouTube. Android Auto is random taking 3sec to 15sec. Most of the time it's quick. Very rare it doesn't connect. But that could be a phone thing.   Now I think they use a Pixel 3XL to run this whole thing which i guess is fine, but the problem is that some apps will not work on old hardware like Disney Plus  Maybe Prime Video too 🤔. they will not update. Iv'e tried getting the APK Disney + but i still couldn't get it working. I have a Data sim installed so i have internet all the time. You can't Hotspot off your phone and connect Android Auto at the same time. Not that you need too, if you want you can hotspot off your phone and run any internet map app (google maps) and you can run the Spotify app on it's own (the app runs better than android auto) You can still access the INFINITI intouch system for all the o.g stuff    P.S i got new non Polarization Sunglasses too 😎 
    • I also don't mean to rain on your parade. But with a 5-10k budget for road only? I'd want to check confirmation that everything IS working correctly and I'm with @GTSBoy for a plan of action here. I'd be checking subframes, bushes, exhaust hangers, interior bits and generally QOL things and CONFIRMING they are working right before thinking about motor. You can get 250KW+ on stock RB26 hardware by simply removing the built in restrictors and tuning the stock ECU. If you want purity that's as far to take it, which I would be worried to do and won't think the budget would allow for when earnestly checking for 30+ year old car stuff.
    • I specifically said buy new performance car because of the use case here (i.e, no track use and fun livable everything/do it all easily if not especially amazing as a drivers car). Tracking an 80K Skyline and an 80K M2 makes the BMW the obviously more risky purchase WHEN something goes wrong you suddenly can't easily fix it with hand tools and readily available parts that you may have a community of people you know available, or years of your own knowledge on the platform to apply. There's reasons you see Hondas and Vettes and RB's and Miatas and such at tracks, you can easily hand-tool repair 99.9% of it in a shed, usually with the tools and the skillset of the owner to apply to it. An i30N is not going to beat a R chassis unless it's got massive problems either. The old cars can, and still do work great. The problem is - and always has been - social media would have you believe it's simple and easy to achieve the results you see online.  People want their car to be like "one of those cool JDM cars" which is the default image people have when they think of  "cool JDM cars" You are paying 25 years of catchup R&D to achieve. Or the knowledge somebody else has to do it for you, which is big dollar restomod stuff.  The bar has been moved and every R chassis that people see/like/enjoy has 25 years of R&D thrown at it, or is owned by someone who did all that work and has that knowledge over the past 25 years. All the survivors have been progressively resto-modded the entire time. OR you slowly bring it back to how it was stock. Which is also prohibitively expensive, done for the love of it. This is what the JDM community is now. This is fine, but "Where do I start?" is either: 1) Don't 2) Take your own slow journey but you cannot compare your progress with others who have had 25 years of R&D and experience building their own cars unless you pay for it.
    • Yep, with the crazy inflation of the value of our cars these past couple of years this became a problem for me too... My solution is to transition to bikes. Everything feels so cheap compared to tracking the skyline lol
    • So, I've been a little busy on this car. I replaced the bonnet struts which is always satisfying but very confusing that nobody else on the planet seems to do this. Its just my routine first thing I do on any car I buy. The boot struts for both the tailgate and the separately opening glass window was a bastard. And, I found a fair bit of rust in the strut cavity. I filled it with rust converter and cleaned up as much of the dirt as I could. There was so much dirt. One piece of the trim was barely hanging on and so I've left it off. I'll try to get a replacement. You can see how disgusting and dirty it all was in this thread; I had to remove the little clips that hold the struts on the ball. The ones I took off had no clips and it was impossible to get them on with them in place. Fingers crossed they stay put. So, I turned my attention to the headlights, they were in a bad way and likely would stop rego. I took the headlights out and found the adjusters were all just loose. So, I fixed those and unclipped the lenses to clean them up. Couldn't believe how easy it was to take all this apart compared to the E90.   I also cleaned up the stockies which was awesome, these are super cool with lug nut covers. They're in good nic but the tyres are shot. I was going to use these for rego but in the end got a fresh pair of rubber for the 17's on the front of the car instead. The front bar of this car is from a late(r) model one. I don't think it's quite LCI but who knows. I'll need to find out. Anyway, the bar was missing the fog lights and the wiring and plugs were for the original ones so I got new plugs and some cheap fogs. I wasn't sure if missing original equipment would hamper my blue slip attempts. Had a couple of these little fellas helping out. But not Ben who got stuck behind the pool heater .... How embarressment.  I ordered new speed sensors for all corners because I knew one was out. I just got cheapies and will replace them with Bosch items when I can find Bosch items. Again, this was just for rego. Alas, it seems the blue speed sensors are not the same as the grey ones. Back they went and replacements ordered. In the end, with my new scan tool, it was just rear left that was shot. Replaced it and cleared the codes. All good now. Lastly, my aux (thermo) fan is being a bit odd. Its powering up at strange times and NOT powering up when I think it should (100C). While this can be caused by a few things, the most likely (for me) is the ambient temp sensor. Given mine reads -40.0C regardless of the temp, I figured it would be good to replace it. In the end, the sensor wiring was abysmal with (terrible) attempts made by somebody to fix it.   I fixed this all up but the sensor is only attached using pins into the wires. The plug is not there. Despite trying and trying to connect it securely it wouldn't work so a replacement sensor and plug is on the way. Oh, I also ordered a replacement piece of trim for the part missing here at the bottom. Ordered from Latvia for $70 delivered. I took a bit of a leap of faith because I didn't have the exact part number and, as usual, there were eleventy billion pieces of trim that looked to fit. Nailed it. Well, its not totally perfect but I think its more a 28 y/o car problem than a trim problem. And, as of today ..... I have bought the workshop manuals 2nd hand off a guy in tassie. 1000+ pages of E39 goodness, hopefully it helps me with the fan. I also have a new temp switch on the way incase its the problem. Stoked.
