Yes, can be in or externally gated. Would still be a while before having a fully functional prototype finalised. -
Its good to have documentation from all range of supporting mods working with the turbo. I will index them in the main page. I've been taken some time off working on my electric turbo again. lol here are some latest updates: The new charger runs of 44V 120AMP of power from a 2x 6S power source with RPM controller. I've installed it on to a Daihatsu Sirion with a 3cyc 0.97L engine. This car makes from 0 to 100KMs in 21secs factory. lol After appling the charger in 3rd gear full throttle it actually made the Speedo rising a tinny bit faster. There is a just noticeably acceleration gain with the charger is activated and not. I'm installing it on the R33 for dyno runs next weekend. hopefully making better result then the previous one. Plus I'm working on a VNT .82 rear housing for the G3s hopefully getting SS1PU's response with 330rwkws top end.

Boost gauge pressure = Actuator spring pressure - Inlet manifold pressure - exhaust manifold pressure.

I can make that direct Bolton to your stock manifold and dump. Isn't that a td06 rear with a 60-1 comp?

You can pay higher rate and spend more time for errors to not/less likly occur. Which is why all of engineering work are carried out locally under my direct supervision. The wheels that I'm using are specifically made by a well know foundry to be solid and heat resistant. Which I haven't seen one cracking even thou they are treated in much hasher conditions. Ie internal gated, pump 98 fuel, high boost. But the part does not comes with a cheap price tag. The TD06 copy, I was told all parts were sourced from Taiwan. I introduced it as a lower cost turbo with intention to generate consumers on a budget, well only countinue if it proven relaible. The price frame on it is impossible to produce the same in Australia. I don't think the failure resulted with efr is in manufacturing process. To me it is in design and engineering print of the assembly. Means regardless of how well they are manufactured, as long as they were manufactured per print, it will have the weak spot. Hoo clutch wise I'm using a Twin plate Blitz. It has never sliped. But horrible to drive on road.

The turbine wheel bends backwards or break vertically during a course of impact. The horizontal crack is from Heat, some thing to do with the material content of the alloy its made of. Generally running E85 and external gate plus not so much boost would keep the EGT low, that avoids issues like above. How ever I have seen similar problem from a T70 Chinese turbo years back that was used on a Ford 4L +T. The car initially made 370rwkws on pump 98 for a while before the driver noticed lack of performance through time. The turbine wheel had lots of horizontal cracks with chucks missing, the edge of the wheel blade appeared rough like a wire brush. Luckily the it was a old T04 copy so I managed to rebuild it with a geninue Garrett wheel and it was all good. Most turbo builders would contract specialized foundries to forge their parts to the specifications they require. The single incident is not good enough to conclude Kando or all other Greedy copies are bad, certainly there are many more working examples plus mine is yet to be trailed.

Remember water does not compress like air. its possible engine has bent conrods, or valves.
-
Let me know when you clutch is sorten. I think I will add the FNT turbine into it as well and make it a more unique TD06 to the generic version.
-
I think I would have no issues doing above, infact I know the SS1PU is slightly larger then the GT-RS all around and was pretty consistent when on the dyno. I'll be back with few more wastegate side updates and can do some comparisons with what Trent's got in his PC. Also found most tuners would retard timing as "insurance" for stock motor when it do hit 20psi. That explains the missing mid range, an update to the wastegate assembly is made, so all new units would have no issues holding boost using EBC with a 14psi actuator. Also the updated module is available for all ATR43 series at a cheap cost. For that Billet TD06 there is no way it can be modified into a stockie bolton the possition of the turbine outlet is way off to stock 6 bolt nissan pattern. So it will have to be the way it is. I'm planing to let trent do some tests on his New Ceffero.

Ive had exceedy brass button clutch it was ok for around 300rwkws. Other wise try extreme clutch. I had them in my 300zx and sil180, they are good.
-
That part is $35 delivered. It's best working with the 14psi actuator and ebc. It will only work assume the cause of the drop is the strength of actuator. Will have no affect on retriction related boost drops.
-
Birds come and get this part after clutch change. The turbo will be able to hold 20psi straight to 7000RPMs with it using a EBC. Should get around 280rwkws with extra 3psi of boost.
-
They are not made to open up 90 degrees. perfectly normal.
-
Yes that's the reason I didn't want to send it out till the new bit was tested.
-
They are similar. The bigger the wastegate is, the cooler the egt, with this hug waste gate and possibly the porting I've done to the rear housing we were been able to run 3 degrees more timming up top. Big internal gate is also harder to boost controll as it generates lot more force acting against the actuator. The theory is to extend the lever, same principle as loosing up a tight bolt with longer or shorter spanner
-
Couple of modifications on the SS1PU's exhaust side and wastegate setup: The new housing is the adaption flange area further machined, now fitted with a massive 32mm internal gate. I horned out the rear housing for better flow, how ever that resulted same effect as a bigger rear housing, both lag and power went a step up, which wasn't what I originally wanted. Still felt ok on road, but missing the zappiness from the original housing. The final result. 286rwkws @ 20psi lol The power isn't imported, how ever I think this simple waste gate mod have solved the boost drop issue with internal gate. Solid lines below was performed using a soft 14psi actuator and ebc, while the dotted lines were using original wastegate setup with 20psi actuator. : Boost curve responded to the EBC perfectly, I can have 14psi as "lo setting" and 20psi as "high sitting". Did more runs in comparison with wastegate mod removed using 20psi actuator. (Blue line with 2 dots was final run with 14psi actuator + gate mod.) I have a spare addon mod for the ss1PU's internal gate, drop in a PM if interested to trail (Birds?).

If you sure that you are going to buy it then I can check for as as I bargined hard with Andy to get that Price on the Plugin ECU for the R33 buying 2 at once.
-
Only the R33 plug in ecu for that price if you had a turbo from us. info at: http://www.skylineecu.com/
-
EBC do help abit. because it can cut out all pressure on the cold side to the actuator which MBC don't. still need a strong actuator to eliminate boost drop thou, but I'm working at a different direction at moment.
-
I think there should be more improvements to be made on Bird's car, I've seen it before as it had lot of stock egr and epa legal stuff on and the cooler isn't great either. Other thing is the ss1PU tested on mine was running on ebay side mount exhaust manifold. http://www.ebay.co.uk/itm/NISSAN-SKYLINE-R33-RB25DET-TURBO-EXHAUST-MANIFOLD-T3-/310281423217?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item483e36c971 Not sure if that did help making the extra power. its available for ss1pu people whom's interested to find out at samll cost.

For the CT12a they are similar specifications as the 2860rs same as what we normally high flow gtr turbos to. He had the stock turbos dyno tuned which was about a year ago and the high flowed ones in just recent. Yes it was in 3rd but with the high flows the transmission can't hold, its slip badly up top. with the TD06sl2, this is should be identical as Kandos as all parts were bought and made from the same factory in Taiwan. The billet 20G compressor wheel has skimmed hub for greater flow, and light weight, in theory making same effect as our 71mm SS2 comp wheel. The standard 20G wheel is also available. Since there are working examples I won't go in to very details in testing what has been tested. As said it is now available for $850 as it is with Australian warranty. In the next few weeks I will turn it into a bolton externally gated turbo for RB25det then apply FNT turbine nozzle to fill in more mid range if possible.
-
Yes also doing XR6 turbos, VLT, 300ZX, VW GTi plus some electric blow dryers and etc. I can't remember who was asking for results off a high flowed CT12a soarers. I got some results from it: That was from a Auto soarer. The thin red line was from stock turbo. The thick red line is initial tune with the map from his stock turbos Thin blue line was final tune. His auto trasmission is pretty much burnt at this stage, should be able to gain another 20kws with a built transmission. They were more responsive then his stock turbos.
-
Save for a plazaman cooler. Or a custome side mount manifold
-
I'll be there 7pm starting the tune on Friday. Its more of testing the wastegate actuator and a newer housing. Should all finish in an hour so its all good if you like to come in around 7pm and see how the tunning goes. I will trail some externally gated ones including the SL2 and T67 combinations with billet wheels and do some modifications no housings from there. At this stage we can supply SL2 units in 10cm T3 turbine with billet compressor wheel.
-
Yea I found it. It looks too linear thou, I pictured it would do some thing that. I should be able to add in lots of meat into the mid range with FNT turbine. Where abouts are you based? I'm testing the ss1pu again Friday afternoon which we can swap cars for a test drive near status or unless if you are in the North side.
