This is the kinda core I'm using lads. I get where your coming from Scott. I guess I need to decide whether I want the car to look stock and have average power, or put in a conventional cooler kit and gain the missing power I should have, if thats the problem.

well thats a recipe for fail right there..get a proper blitz return flow or something..even a Justjap one would be better than that junk..

I tried to put my T67 10cm housing on my 20G over the weekend and guess what...it didnt fit. Its too small and hits the turbine. So tried the 10cm housing off the TD06H-25G I had and it swims. So it seems Trust run a different turbine again on their twin GTR setups as my20g is one of the pair off a friends R32 GTR

Seems its somewhere between the L2and H. And I have seeb back to back TD06H-25G vs T67-25G and the T67 made 15-20rwkws less..all in the turbine it seems...was a rad laggier by 100-200rpm

The reason why I went with that type is because I'd smack the shit out of the bottom pipe due to the cars height. I'll probably go conventional setup. Could an intercooler restrict the amount of boost a turbo can make, or limit power at a certian point?

Roy I'm sure you are aware but:

TD06SL2 = 61mm

TD06S = 65mm

TD06SH = 67mm

So its no surprise your regular TD06S doesn't fit the T67 housing but is too small for the TD06SH........... Its meant to be.

Unless I am missing something the above is your answer.

In terms of flow the TD06SH > TD06SL2 > TD06S.

I hope that helps..

its not limiting the amount of boost it can make, its limiting the amount of boost that you can effectively reach because the knock threshold turns to shit.

that intercooler would be by far the worst possible option you can have.

IMHO it would hold back power to a point close to the stock side mount and would also harm spool.

CHANGE IT AND THEN KILL IT WITH FIRE.

Got a mate with a normal return flow intercooler kit, I'll swap with him for a few days and see if anything happens eh (and see if I could actually run such a setup at my height).


Cheers for the advice guys :D

If you have a read of the hypergear thread the above shown return flow is good for about 250kw until it encounters the same issue.

I think 1 or 2 members have achieved more with top notch jap branded kits... but that are more or less one off cases.


Go the conventional route and ditch the headache and question out of your mind!

But strange thing is that this turbine doesnt match any of those. The T67 that I swapped housings with was the twin T67s that repalced the twin 20Gs on the same car and I wonder whether the turbines are specific to twin GTR setups!?!?!

On the same dyno my car has if anything made the same power but with better reponse than the several L2s that have been tuned. I had bought an L2 based on what everyone had posted but after a few more RB20-20Gs rolled through my tuners workshop and we had compared results....well I sold my L2 to Kris for his drift car. So I wasnt convinced it flowed any better. Perhaps if an L2 fella ran E85 and we could see if they flowed better at 24psi and 300+rwkws

That's very odd. It may be something like a TC turbine or similar.

Can you get me the Inducer and Exducer measurements, along with a blade count? I will have a look and see what it marry's up against.

From what I have found online a TC06 will be 12 blade and 64mm. Smaller than a normal TD06.

That info may not be accurate though..

The TC06 turbine blades have an obvious cup shape to them.. Its not what were used to seeing in terms of turbine aero. Very 80s.

Kando have had a few oddball (unexpected) units on offer, including the Hino (truck) spec GT3576 (plain bearing, split pulse IW turbine). Not surprised to see that GT3071.

Likewise the TD06 hybrid with TO4R compressor, it's been around as have other hybrids with the old-school 60-1 compressor. Maybe not the most efficient stuff but they can work reasonably well at the price.

Re the TD07 unit, I think the main thing that will differentiate them from the TDO6 based units is the size of the centre section, bigger diameter shaft, and no water cooling option. Take a cue from the T67-25G.

Hey Dale, I already have a TD06sh-25G so I was thinking if it don't make enough power I might convert it to a TD07S-25G. I finally pulled my finger out and decided to fix my wastegate now that I don't melt when I walk into my shed . Seems all the info I find is where people have them on rotary's.

Yeah td07s 25g with 16cm rear seems the turbo for a rotary, but i dont think kando do that rear do they?

Also they are offering a t04 compressor housing and wheel kit, just curious if anyone has tried to fit this to a stock nissan turbo? I'm seriously considring buying this kit, having the shaft balenced then seeing whats possible.

Any suggestions stao?

, but

The TD06SH + 12cm should offer a fair bit more turbine flow than the SL2 + 10cm found on the T67 25G. I think that the SH will be enough to handle all the flow a 25G can throw at it so maybe pointless going for bigger turbine unless you're looking at capacity bigger than 3 litre. I can't find hard evidence on the TDO7 specs but it seems likely to offer nothing other than a 0.5mm bigger shaft.

I'd say run the SH and see how it performs.

    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
