Interesting, is that on a 2.6,2.8 or 3.0, I have had good success with the twin GT-RSs so far but the exhaust side is becoming a restriction on the 3.0

So even the TD05s with the slightly bigger exhaust wheel and a good comp wheel should help

Will be interested to know if the 68HTA comp wheel can be fitted to either TD05s or TD06s

This is in reference to 2L motors in single IWG configuration.

I believe that the resultant geometry of the enlarged housing (its made for TD05H wheel) is not adequate for the 61mm TD06SL2 and the character sucks. Both parties I know of have struggled to exceed much over the 200kw mark. A change of turbos has resulted in far superior results, one of them switching back to a Kando TD05H-18G (T518Z).

I think the mentioned 9 blade TD05H combined with the 68HTA wheel could be mighty promising at your level, but am not sure the cost exercise would yield benefits over pre-fabed Kando billet 16G units.

Never heard of that issue but don't really know anyone who has tried a T25 TD06 kando off the top of my head... Though I was sure I had heard of them.

A really quick Google brought this totally reasonable result up and no evidence of any dramas, can you point us at any reads on the drama you are talking about?

Hypergear mentioned some thing about housing geometry in their latest T28 turbo. Not sure what size they ended up using, their latest ATR28 ss2 is pretty amazing for a little SR.

He cropped the larger turbine until it was the maximum size the T28 housing could accept.

Lith, 260 is a very reasonable result. The two I know of (known from face to face interaction) failed to exceed 220kw.

Well it seems it is definitely possible, hard to know what to read from it when a couple go wrong... Entirely possible there was something else at play there but with so little info it's a bit hard to make a sweeping judgement. I do know someone who recently had a poor result with a completely unrelated brand of turbo where someone shoved a big wheel into a non native turbine housing and that bombed quite badly so it seems plausible I guess. I wish I could remember where I am sure I heard or saw someone with a similar combo which made good power, as it was discussed when we were plotting development for my mates S14. The 16G was selected because it was going to suit better, we had no indication or assumption a T25 TD06 would underperform, well aside from the fact that with stock cams it wouldn't make too much over 200kw on petrol.

. Hence not being considered a great match for his needs as he was unlikely to upgrade anything else for sometime to come

  • 2 weeks later...

I know this question has been asked many times but If any one has first hand experience with the Kinugawa Td06h-20g 8cm Rb20det bolt on kits that are internally gated Please Say what you think.

Ive heard that the gates are to small and cause bad boost spike?

Ive been told they dont spike as much if you run a higher Boost through it ( around 18 Pound ).

Ive tried to search other places and havnt found much, just people bagging them out.

I don't have first hand experience but have read In other forums that people are just modifying the waste gate and having no problems at all. I know they get to it with a die grinder and bore it out a bit and the flap seems to be fine how it is.

T67 looks like its going to fit fairly easily with a 25mm or 30mm spacer

looks like there room to go even bigger turbo (if air con is removed to make the inlet easy)

(this is on a 34 gtt) I'll post pics once I find a spacers that's not $95

feel free to tell me what stud sizes I need to :)

For some reason I thought I responded to this - of course they can :D I had even been pondering trying to buy some bits and making some hybrid things to experiment with though I'm not sure if I am THAT motivated.

It fits fine, I even managed to fit one low mount on an s14 with a little grinding.

Make sure the spacers are the shape of the hole in the manifold, not the size of a T3 gasket which is much larger.

I thought you had too :), that is very interesting, how hard would that be to get "GTR" housing to make it a bolton for RB26s, looks like I might be up for new turbs soon so that maybe an option, the billet Kando bolton TD05-18g are what I was thinking but these give me something to think about

I wouldn't imagine it would be ridiculous, just get the Kando housing (or something that will bolt onto the Mitsi plate) and modify it to suit the profile. In my make believe world where I have more engineering skills I like the idea of designing a custom RB26 bolton housing that has a diffuser area etc which better suits the 68HTA wheel, etc. I am sure that a turbo with matching (where it counts) outlines to the stock RB26 housings could have better flowing internal geometry, to allow for the 40-50lb/min flow per turbo you need for stock mount madness.

Just run those housings. They are circlip compressor covers so easy to clock them however you want. Just weld alloy inlets to the compressor cover...I think they would simply be too big, even on an RB30....though would be sure to make uber power considering a friends twin TD06-20G 2.7L made something like 550rwkws on race fuel years and years ago.

Yeah I would consider either to be most suited to the lunatics who would otherwise be putting a big single on their car but want it to be low key, under the bonnet at least haha

Lol yep that would be me :D

The T618z are what I wanted for this build but couldn't find any for sale and settled for Piggys GT-RSs, and as much as they make good power with decent response on the 3.0 the exhaust side is choking it

Now that I'm getting a bit of white smoke I'm thinking they are on their way out so now trying to decide between TD05s or 06s, I think the TD05s with the billet 18g comp wheel and 9 blade rear should show decent improvements on what I currently have with out hurting the response to much, but then there is the TD06s with the billet 20g wheel and 9 blade rear that would make massive power for low mounts but at what cost to response

    • Very nice - I also have a 92 GTST and hardly see any others around these days
    • When I need something else to edit, I use Movavi. A friend who does video editing on a daily basis recommended me) it's an easy video cutter to use for beginners
    • I need to edit some videos for work but I'm not good at all this. Which video editor can you recommend?
    • I think you're really missing the point. The spec is just the minimum spec that the fuel has to meet. The additive packages can, and do, go above that minimum if the fuel brand feels they need/want to. And so you get BP Ultimate or Shell Ultra (or whatever they call it) making promises to clean your engine better than the standard stuff....simply because they do actually put better additive packages in there. They do not waste special sauce on the plebian fuel if they can avoid it. I didn't say "energy density". I just said "density". That's right, the specific gravity (if you want to use a really shit old imperial description for mass per unit volume). The density being higher indicates a number of things, from reduces oxygen content, to increased numbers of double bonds or cyclic components. That then just happens to flow on to the calorific value on a volume basis being correspondingly higher. The calorific value on a mass basis barely changes, because almost all hydrocarbon materials have a very similar CV per kg. But whatever - the end result is that you do get a bit more energy per litre, which helps to offset some of the sting of the massive price bump over 91. I can go you one better than "I used to work at a fuel station". I had uni lecturers who worked at the Pt Stanvac refinery (at the time they were lecturing, as industry specialist lecturers) who were quite candid about the business. And granted, that was 30+ years ago, and you might note that I have stated above that I think the industry has since collected together near the bottom (quite like ISPs, when you think about it). Oh, did I mention that I am quite literally a combustion engineer? I'm designing (well, actually, trying to avoid designing and trying to make the junior engineer do it) a heavy fuel oil firing system for a cement plant in fricking Iraq, this week. Last week it was natural gas fired this-that. The week before it was LPG fired anode furnaces for a copper smelter (well, the burners for them, not the actual furnaces, which are just big dumb steel). I'm kinda all over fuels.
    • Well my freshly rebuilt RB25DET Neo went bang 1000kms in, completely fried big end bearing in cylinder 1 so bad my engine seized. No knocking or oil pressure issue prior to this happening, all happened within less than a second. Had Nitto oil pump, 8L baffled sump, head drain, oil restrictors, the lot put in to prevent me spinning a bearing like i did to need the rebuild. Mechanic that looked after the works has no idea what caused it. Reckoned it may have been bearing clearance wrong in cylinder 1 we have no idea. Machinist who did the work reckoned it was something on the mechanic. Anyway thats between them, i had no part in it, just paid the money Curiosity question, does the oil system on RB’s go sump > oil pump > filter > around engine? If so, if you had a leak on an oil filter relocation plate, say sump > oil pump > filter > LEAK > around engine would this cause a low oil pressure reading if the sensors was before the filter?   TIA
