What I would like to do with my next car is have the wastegate pipe exit off to the side of the car, just like Top Secret's Supra. Then you would be able to see flames :) Most of the wastegate pipes just dump to the ground, and are underneath the car so you can't see the flames, just hear the bark. I guess the wastegate pipe is just like an exhaust without a muffler. The sound probably depends upon the specs of the turbo? I don't think it's affected by the wastegate, because after all it just acts like a valve.

Good choice on the manifold GTS-t VSPEC, hope everything goes well. Should be interesting to see the results. Just a question, when peope custom make manifolds, how do they decide the shape? Do they equal tune/length the pipes of the manifold? Or do they just make it up? I thought equal tuning would be important - to have a constant pressure througout?

I have a trust type R, which is plumbed back and is reasonably quiet. In fact just about everything is pretty quiet (except the screamer), the exhaust definately is louder with new turbs/manifold but has a really nice note to it, much angrier sounding, but the pod noise is completely gone with the new box.

Evan made my RB25 tuned length ceramic coated mild steel manifold for 1200, ceramic coat of manifold and dump was around $200.

Sounds good Steve. Is the "quiet car" so as not to attract unwanted attention? Eg red and blue lights. That's probably a wise thing. I find it very discouraging if cops are out there and defecting a lot of people. All your hard work has to be ripped off. What a pain! Hope it doesn't happen to anyone, but I'm sure many people here have already had the unpleasant experience.

right, wasnt sure as i'm looking into picking up a turbosmart ultragate or something similar,

heres my problem, not making any difference from 14 psi and over,workshop thinks its cause of the wastegate (T04) it had 2 "bedsprings" hanging off with one attached to the turbo and one not, due to the seller of the car taking it off so i wasnt learning how to drive it with it pushing out close to 1.5bar

thought it was a restrictive cat but later found out that it was gutted anyway, so replaced that with a 3 inch and still the problem remains.

any suggestions?

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
