As for those twin scroll turbine housings from ATP , have a look inside them if possible because some people reckon they're a bit dodgy looking . I've no idea who makes them and no ones said they have Garrett markings on them so anyone's guess .

A .

just received myne yesterday. has ATP cast onto the housing so i assume its made by them. some of the machining leaves a little to be desired and the outlet area looks like a choke point but hopefully it'll work a lot better than the IW housing i have at the moment.

some shitty phone pics. thats a 3" v band flange sitting on both sides to give you an idea of the small diameter inside, very different to the garrett housings which are a smooth and progressive opening from the turbine size to the flange size as in the first pic.

found one. anything in particular you want to see? took shitloads of photos anyway. one more thing i noticed is theres no machined area around the bolt holes for a nut to seat, might have to get into it with the grinder.

Is that a twin scroll internally gated turbine housing?

In regards to other questions asked here, the 1.06a/r T4 twin scroll GT3076Rs spool AWESOME in all the cases I have seen - quicker than the .82a/r T3 housing when used with a proper T4 TS manifold. It'd go very very nicely!

Hell, a GT3582R with a 1.06a/r T4 Twin scroll housing spools similar to a .82a/r T3 GT3076 :D

When your fit the CHRA you might want to check how far the CHRA bolts protrude into the volute. Try and grind them back so they are flush with the inner wall if you can.

This is a tip that Full-Race mentions on their web page with regard to the .78 twin scroll housing....it might apply to the 1.06 housing as well.

That's good to hear...

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
