Really considering the 8cm rear housing on my T67 25g really would like some more response but dont want to change turbos only making about 140kw at 4 k would love some more power in the 3800 4500 range

Truth is if i could yave my time again with singles on the RB25...TDO6-20G with 8cm if on E85 or 10cm if on 98

The 8cm is really too small but with E85 it masks the mismatch. If 98 you need the efficiency on the exhaust side and IMO need 10cm

The 20G was just pulled everywhere. Perhaps if my motor liked boost i would have liked the T67 more. But i had problems with the engine not making more power at 22psi than 18psi...assume its valve springs in my motor. Lol so i reserve to change my mind if with 24psi my T67 had made the 360-370i expected i may have liked it more than at 330rwkws which was only 15rwkws more than what i strangled out of the TD06-20G

My RB25 and TD06-20G 10cm on E85. This is straight off the external wastegate but ill be back to have the ebc dialled in hopefully tip the 300kw unopened ;) . Would buy another one of these turbos time and time again.

Have played around with my exhaust cam gear to bring boost on 500rpm earlier witch I believe will noise over up the top end earlier? Mainly street driven so response is key to me!

Keen for a retune.

I've been scrolling through alot of the pages in this thread and couldn't find many people using the TD06H 25g at all. I've been trying to read up on them for a few weeks now. I have a Rb25/30 that is just a slap together engine pretty much that I had tuned with a Kinugawa td06sl2 20g 8cm. Although it has pretty much instant boost, it lacks of go up around 5000 RPM, I normally don't rev it past 6000RPM. It also wasn't making any more power above 16psi (304rwhp) with a 38mm External waste gate welded to the rear housing.

I drive the car atleast 3 times a week on the street, Gymkhanas, Time Attack and Drifting. Im not really after alot of lag.

What I want to know is how Responsive will a H 25g 10cm be, Will it make full boost by atleast 4000RPM? Does any one have any experience with these on a RB25 or Rb25/30? Dyno sheets? I'd love to hear your experiences!

Td06h 25g 10cm makes full boost bye 4 on a rb25 so i would say ure probally looking at 3500 3600 full boost and still restrictive uptop.

I think something else is coming into play with your low power figure though

The 30DET in my 33 is running a TDO6H-25G 12cm single scroll, sitting on a Hybrid manifold and running a 50mm gate.

Running just on 17psi it's making 375rwhp on petrol. Full boost in 4th gear at 3500. Peak torque is held from 3500 to 7000, so turbine doesn't choke it.

Car is track only, in my build thread there's a few links to in-car video.

I would describe delivery as progressive and extremely predictable, traction friendly. But a touch lazy, and not necessarily what I'd want for motorkhana, hillclimb or road use.

The 10cm housing should be pretty good choice especially if you run E85 or water injection.

I'm looking to try one at end of season this year.

Has anyone had any issues with t67 fitting on new 6 boost manifold  i have a pre 2012 6 boost manifold and it doesnt fit my t67 on it as the t3 flange is parrall with engine so compressor housing fouls bye like 10 mm do the new ones  have this issue  ???

My t67 was hitting the rocker covers sitting on the 6 boost.

i just rotated the compress housing till the outlet was pointing to the ground and it fits then made my cooler piping from there. 

Its hard to see in the dark photo. It's on a 25/30, also fitted on my 25

Im changing turbo setup now noticed the oil seal in my turbo has been leaking.

Anyone had there oil seal replaced might get it fixed to go back on my 25/30 build.

But for now im going to a hypergear hiflow setup

Current tune. Only difference is 268- 272 9mm cams to keep the vct and 22psi.

    • OK, that is a helpful description, because that sounds exactly like a bleeding issue in the clutch....these are hard to bleed manually even when the damping loop has been removed. I'd suggest bleeding again....start by filling the master cylinder up and opening the bleed nipple. Come back and check every now and then that the master cylinder is not empty. Let it gravity bleed for a few hours and see if that improves
    • I replaced the whole clutch line with the chase bays braided hose, I think it removes that loop, is it the short hose that comes immediately off the slave or is there a drawing in the manual to find what you’re referring to? It was just re-bled when I upgraded to the nismo slave, old slave worked fine but I thought that might help, didn’t change a thing. It’s like the first half of the pedal is pushing air and then when it finally actuates the master the friction zone is tiny. Makes it practically impossible to launch the car
    • Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.
    • I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it
    • If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣
