Massively better. If for no other reason than you don't have to have a separate tank, pump, controller, worry about WM running out, etc etc etc.

The problem with water methanol is that it is a parasitic loss in the engine. You spray a lot of water in because that's where the cooling comes from, but it isn't fuel and it has to be heated up to exhaust temperature. That's an energy cost. The cooling in E85 is from a large chunk of alcohol, which both offers good cooling and is also a fuel. So there is a much smaller parasitic load along for the ride (there is a little compared to straight petrol in that there is more water in the exhaust gases of alcohol, which does have to be heated to exhaust temperature, but the effect is not as bad as with WMI).

on a R33 motor right? don't the ringlands let go? I know R34 RB25DET NEOs are built as well as tanks

yeah, ringlands are fine provided the tune and engine it self is sound, one engine made high 400's but my testicles were far to small and we stopped pushing.

      I like it when the counter chick leads you out the back into the racks and says "have a grub around in here and see if you can find what you need. I'll be back in a few minutes. Just left me in front of a massive motorised shelving system and 2-3 million fasteners, so I could find a peculiar SS shoulder bolt with cap head. Gotta love country towns.

      I used this https://osgiken.com.au/product/os-giken-os-250r-lsd-gear-oil-80w250-1-litre/   shut my nismo 1.5 pro up by heaps…. Not silent though. Gives the car character and personality. It ain’t a carolla. If you want silent, put a quaife in it.

      It's about the same time for me from Bunnings, or the Fasteners. My big push away from takeaway food, and gluten in general keeps me away from the Bunnings Snags too! Weather up here, I've been out for two walks today in the beautiful sunshine. Had a few little drizzles, and some wind, that honestly, a tin of beans and I could compete on how harsh she blows Thankfully, being this bit inland, we're not getting anything much really. Will probably pick up a bit more when/if Cyclone Alfie decides to come ashore. A few areas in the GC though, and south into NSW are really getting smashed though! Right now, I'm just annoyed Alfie hasn't hit, as I'm not allowed to crack into the BBQ foods like the bacon and eggs until the Cyclone hits "In case we lose power"...

      I love fastener joints, the price difference between them and joints like Bunnings or Super Cheap is amazing, and they either have exactly what you want, or they can get it to quick They have even given me some for free when I only needed a couple of specific size In saying this, I have paid premium for fasteners from Bunnings if they have the sizes I need, but only for convenience really, as my local is only 10 minutes away, the Sushi joint near them is also a consideration  How's the weather Matt? Stay safe mate

      Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.
