i can't say much about the atr43 , from what i've read there's heaps of variants . the person to ask would be STATUS , he may be nice enough to pm you a dyno sheet of each on cars with similar mods? for $8-900 i don't think you can purchase a hypergear of similar size for that?

Has anyone tried the td06 l2 10cm on a rb20??? i'm hanging out to see whether the 10cm is too laggy?

Is there a 8cm L2?

For me its all about the RESPONSE on the street - I know you cant go past stock - but how does the hypergear atr43 on a 280-300rwkw GTT / GTS-T compare to a 3071 or 3076 on the same car at the same power level with similar stage 1 mods - exhaust, FMIC, ecu, boost control, pump, injectors etc??

I ran my TD06-20G with a 10cm housing. The 8cm made the same power and was far more responsive in the 4,000rpm range. The 8cm doesnt like much more then 20psi due to back pressure, so if you want to run more then 20psi then perhaps the extra top end will make up for the loss in mid range...but i doubt it. That said I am about to go back to the 10cm housing and some baby cams for shits and giggles. I know I will be a laggy POS with not hitting 22psi to about 4,800rpm but curious to know how much more then the current 272rwkws it can make with the bigger housing and some cams (note, that cams with the 8cm dont seem to do anything as it seems the tiny lil 8mc rear is the cause of any restriction...not cam duration or lift)

I honestly dont feel that any of the above are going to give you a real feel of response. The stock turbo, in my honest opinion, was a lazy POS. Far better could be had.

My opinion of response would have to lie on a HKS GTRS. I am also going to go down the road of a TD06SL2-20G on my 1J and see how that turns out. It should meet and exceed results of a 3071 with what I anticipate will be far more midrange and outright response.

To utilise the currently available kando version of this turbo you will need a gate adapter made.

Its called atr43 super street lol. There's an ss-2 which appears to have 3071's response with 3076's power out put. check the dynosheet section. In my opinion thats the cheapest option to get power since every thing bolt on to factory setup. The Kando turbos are cheap option for 400rwkws E85 track machines, on every day road use it’s not that practical, specially with 100% defect rate. Don't hijack this thread, Post your hypergear questions into hypergear's thread.

Try go for a drive in one. You'll see that what's on the dyno sheet doesn't necessarily always tell the true story about power delivery, response in/out of gears and so on.

I just got an email back from Eiji, there will be a 8cm T3 IW housing for the L2 available end of May... Not shure about an 8 cm T3 external gate housing...

Justin.

cheers justin , pair for xrated?? :P , i was about to buy the t25 variant and use a t3-t25 adaptor . an 8cm with v-band exh out would be a winner though

Hey Toff... I'm still in two minds about what's going to end up on XRATED. It's either going to be a pair of low mount GTRS's OR a pair of TD06L2 8cm Trust turbo's... what do you (or anyone else) think??? (stroker- dog box- 4.3:1 gears) I've got manifolds, trust pipe work etc for either set up.

... oh and 400hp worth of direct port nitrous if I get exited :-)

But anyway... I just emailed Eiji and he got back to me in a couple of days. I'm thinking about swapping out my Precision Turbo- Billet 5557 in my (rb25)32 gts-t for a Kando... Either a Kando or a Hypergear 'super response' for a crazy 220rwkw (I have 4.3:1 gears in the gts-t).

Cheers

I wonder if that 8cm T3 IW is going to handle the flow of a 2.5L....

I am days off ordering my SL2 20G and would LOVE an IW housing and am even thinking 8cm might be the ticket for BS response.. However I really want to see the thing cracking 260rwkw.

It would break my heart to get the thing on the motor and be limited by the 8cm or the small IW wastegate flapper.

FYI trust examples pull over 400ps on jap hub dynos ala youpoop.

PPS the limitations of the wastegate flapper is what stops me getting one with a 10.5cm evo rear housing. I will need a custom manifold regardless (1JZ) so making one to suit this would be no drama, especially considering I am going to use the factory 3:1 manifolds and make a J-pipe. Maybe I should reconsider this option... Input please?

Just a warning regarding the internal wastegates on the Kinugawa turbos... The only negative feedback I could find on the net about their turbos were issues with internal gates having boost control issues!

Obviously the 8cm T3 will be a different design, but just a warning. Also we will never know till someone gives it a go so who is game?

for your style of driving justin i'd be going for the td06's :ph34r: nitrous fixes lag :whistling: . rb25 r32 is a daily?

...what- who me?? my driving style... I drive realy slowly. It's the missus who drives to fast :whistling:

Yeah, td06's I think.. why not- they look cool too... (gotta keep up with the kool kids) ba h ah aha ha. Gas is good! maybe I'll just run one bar and 300hp of nitrous :domokun:

RB25 r32 is my thrasher/ missus car (was anyway- was my excuse)/ drifter/ gymkhana- motorkhana car...

I got a black S2 stag for daily duties/ tow car.

Im thinking to J-pipe my factory manifolds and run an evo twin scroll item.

Assuming the exhaust wheel is big enough for the flow, what is your thought on the waste gate flapper being too small? Think it would cause boost spike and then inability to hold boost up top? Or think it would cause it to run higher boost up top.

Hypergear has had some interesting results in regards to this, but it would be hard to cross reference the two. Obviously running the evo 10.5cm rear also negates any issue with the kando IW housings not holding boost (his evo turbos would run genuine or ex mitsubishi items).

I knew there was going to be a grain of doubt pop up with the IW plan...

I gather you know that you would need an Evo10 turbine housing because the 4-9s use anti clockwise rotation TDO5H"R" turbos .

The aftermarket seems to be getting a lot of horsepower (for the frame size) out of these Mitsy Evo twin scroll turbine housings but they are boring them out for larger turbines to do it . Being twin scroll twin integral gate they need separate waste passages for each half of the housing . Early ones had two holes and two flat valves where late housings ie 8MR and 9 use a single larger round hole with a divider , miror imaged "D" shape .

I don't remember the exact specs for the evo 10 turbo or the output of a std 4B11T engine , I am told by reliable sources that they run 21 pounds of boost std so the flow paths can't be too small . I must look up the turbine and T housing spec of those things .

A .

You are correct reharding the R type turbines, however the TD06SL2 wheel has been used in these housings to great success.. I am thinking the SL2 wheel must also be reversed OR the housing design makes little difference provided the compressor wheel is also the correct type.

I need to call GTPumps I think..

You have to agree, this is a VERY interesting concept no?

I ran out of time to post yesterday but I did find the Evo 10s turbo spec - its called TD05H-152G6-12T which means it has a 12cm twin scroll turbine housing . Thats getting up there size wise and def getting into what a 2.5L six would like . Mobs like Forced Performance and CBRD in the US do quite a few effective high flows based on reverse rotation 4-9 turbos and now the 10 so things are out there to play with if you can get around the Mitsubishi Evo flange pattern . Also as a heads up the staggered inlet ports on the 10 turbine housing are the opposite to what the 4-9 reverse rotation turbos have so factor this in if you're getting a manifold made .

Not Nissan related but the Evo 10s turbo is clockwise rotation because its on the firewall side of its transverse engine where the 1-9 are out front on the radiator side . I think this may have been because the out front type have a greater length of engine pipe between the dump and the cat which no doubt increases the time it takes to light the cat up at cold start .

    • Update for the sake of closure   Ended up getting the intercooler piping all sorted, new plugs and yellow jacket coils, and she was idling mint until it warmed up while I was bleeding the cooling system. Found the misfire to be localised to cyl 3 by unplugging coilpacks, ran a compression test, that checked out, then decided to get a mate to check if that spark plug was firing out of the motor. Upon cranking it over, with the injectors disconnected, the car actually fired and ran on a couple cylinders and heaps of fuel came out the top of cyl 3 I'd say that injector's either spraying incorrectly or spraying far too much, which is fine as I'm planning on replacing them anyway I'm planning on making about 250kW on flex fuel, and have a set of 1000cc injectors from ozautosport, obviously overkill but I'm planning on building the motor and running more boost further down the line, do you reckon they'd be too big for a smooth idle on 98? Thanks for the replies gents, much appreciated
    • I'm confused. You said you want to "remove the clear coat from most panels" but it sounds like you are actually doing a full respray? Few random things to add -  If you chase the blistered paint with 120 grit, I can almost guarantee you'll chase it down to bare metal (that's fine). But if you paint the car from here, you'll have nice little indents where ever the blistered paint was. The new paint won't magically level out the low areas, you need to fill them. Which leads me to the main point I wanted to add, make sure the whole car is flat before you paint it. All those areas with blistered paint you sanded out, make sure to fill them and triple check they are flat with a block guide coat. I'd also check the whole car is flat with a large block and guide coat but yeah up to you if you want to go that far.   
    • 300hp (225kw) is barely outside the standard turbo's range with a bit of extra boost in it (200ish). If you are going to change the turbo you should aim for 250-300kw (330-400hp) to make the expense worthwhile
    • A couple of things, firstly omg that turbo is expensive! $3,000 USD for dinosaur technology is robbery. You could buy a G series turbo and have a good amount of change instead.  If you want a good budget option, have a look here - https://hypergearturbos.com/product/rb25dethighflow/ If you are keen to spend more, have look at the modern turbos, Garrett G series, Borgwarner EFR, etc. Have a look at the RB25 dyno results thread for inspiration.  If you upgrade your turbo to something that will support the 300hp you want and only "probably" have Haltech ECU, your car will only "probably" run. Actually, no it won't run. You are going to need the ECU and injectors at the time you do the turbo upgrade.  No thoughts on "this much boost" as you didn't say how much boost that actually is. Having said that, plenty of unopened RB25's making even more power then what you are chasing.
