I don't think its fair to talk about twin scroll in light of gains over open, not at all. I believe it is more so a different result than it is an improvement as such.

The twin scroll will definitely bring boost on earlier but will also roll on/off smoother and give an overall more linear feel. Not everyone is into that, Owen's GTX is a good example. He and I had many a PM about that and it was honestly determined that he just wasn't happy with the twin scroll efforts. He much preferred the brute delivery of the open .82

In my own experience I am much the same. Not worried about smooth roll ons and how early it starts to make 'some' power. I am more concerned about how easily accessible power is and how hard it will pull at that point. For that I would say a good open housing will definitely deliver.

Moving up? Could be seen as moving down. Those who believe material objects determine social hierarchy sit on a lower rung in my books. C63s appeal to those people, and their cardboard cut out frien

have you fixed your boost creep issue with the internal wastegate ?

Never really had boost creep problems, it's a back pressure issue. The exhaust housing I have is a little small for my RB30 with it's ported head, but I'm completely happy with the result I've got.......it's got easily enough HP for a road car (630 4whp) and the response is awesome. I could get more out of it if I changed to the larger housing, but I'm not going to bother.

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
