Time will tell. The kando ig failed with similar setup

[simpletool]

Hey Stao - if my AX53B70 ever goes kaput do you think you could make something up for me with the housings off it? It looks like it could do with a couple more mm in the both the compressor and turbine wheels. So far it has been nothing but rock solid but I only use at 1bar max. Thought I'd ask as I wouldn't mind pushing it a bit more.

I'm only looking for 250-260rwkw, I figure the turbine housing on this would be ideal for that power level.

Yeh well I wouldn't expect it to be a hell of a lot, but considering I'm chasing a restriction in my setup somewhere, I just want to know that everything is as good as it can be.

Run it without a dump pipe

[hypergear]

The problem with large internal gate is boost control. means it will have more boost tappering off in general as there will be more load on the actuator. It is a bit of a concern on the new .82 IW housing assembly, might need to run a 2~3 actuator setup or some thing similar to eliminate boost drop.

one off 38mm internal gate SS1 turbine housing.

why didnt i get a 38mm ss1pu lol

[DVS JEZ]

I wonder if because there is less velocity the 38mm gate might actually help

[LANDSCRIBBLE]

Stao Is that housing there compatible with the ATRG3? Looks much nicer than my current one.

[hypergear]

Have big gate keeps the turbine housing cooler, but harder to boost control. how ever also depending on applications, we do get XR6 BA turbo waste gate jobs often. From my past experiments bigger gate drops more boost. How ever that was before the innovation of all the wastegate controlling methods that I've used today, So might not have the same drop behavior, while makes more power on lesser boost just like having an external gate.

And yes the machined 3inch Vband adaptor fits All .63 and .82 ATR43 series.

[LANDSCRIBBLE]

Sorry i meant the housing in your post number 6345.

[hypergear]

That housing is only for a SS1xx turbo. G3's got a much larger turbine housing, the cut on the adapter is currently the same.

With way too much time on my holiday in Japan to catch up on some reading and not spending as much as anticipated etc I've made a list of jobs to do hopefully before end of the year.

Buy an Adj ex gear and dial in both cams as they are both currently retarded.

Modify or change dump pipe til it matches turbo perfectly. Awaiting Stao's results currently on new v-band piece.

Quieten down rest of exhaust

Section off pod filter and set up a cold air intake

Swap internals of plumb back BOV as I blocked atmo port but it keeps reverting. Need recirc port to open first.

Gas up air con.

And for good measure install WMI

Will order bits tomorrow so it starts arriving as I get home

Rounding the edges down to what we felt comfortable with

SS2 turbo to get installed this weekend

[t_revz]

So the bit on the left is still 10mm in from gasket but rest is ok? But hard to see.

That's pretty poor especially after opening it up more

[blah_blah]

We were able to round down the edges right up the gasket.

But unable to open her right up as the walls were getting thin.

Yeah prob only 10mm

She'll be right! Still much better than before!

Should get tuned by Trent next week so will see how the results go

[hypergear]

Please let me know your date, I would like to come and witness your tune and take some video footages. cheers

[LANDSCRIBBLE]

skid vids!

No problem will do!

Getting a mechanic friends to do the work out of hours so could be a one or two weekend job, pending if things go to plan or if we have time.

Haven't booked at exact time with Trent yet but he said he could squeeze me in any time. But will let you know!

Did you get a genuine nissan gasket from JJR for the dump pipe too Tony?

[blah_blah]

Yup got a genuine turbo gasket set but not from JJR. Including the gasket from the turbo to dump pipe.

Parts to go on this weekend:

• SS2 Turbo
  
• Manifold from Stao which has been opening up a bit for better flow
  
• ID 1000 Injectors
  
• 3Inch JJR bellmouth dump pipe
  
• Cometic plenum gasket (When I do the injectors)
  
• Cometic manifold gasket
  
• Genuine turbo gasket kit
  
• New nuts and bolts
  

[hypergear]

I'm not sure if the stock R34 plenum gasket is rubber or not. you need to get the metal one with rubber O rings in them. I found the rubber ones gets blown out under high boost.
