99% of the time a -10an hose is big enough, but like I said have a look inside the fitting. see how much smaller the hole in the fitting is compared to the ID of the hose, I can tell you now it wont be 5/8" inside the fitting which restricts the oil flow

Zeeb you mean the OD of the hose.

The issue is a 5/8 ID will be fine, but buying a 5/8 braided hose might have a smaller ID.

5/8 is 16mm, so if the flowpath (ID) of the hose is 16mm wide then youll be right. :thumbsup:

from what garrett/rotamaster/mtq have told me is to use a 1mm restrictor in the oil feed fitting its a must it might not happen staight away but it can happen dual bb turbos need no where near the ammount of oil as a journal or bush bearing as told to me buy these places ive have to many dual bb seals die due to no restriction the seals are only rated to 65psi or so they said and its safer to use a restriction then none soi think im just goin to get one

      Yeah well per the video it took 15s for the stock unit to start up....even if I give it a few seconds discount for starting that is at least 12 sec before you get a reverse camera if you are trying to leave a park.  The android unit is way faster, but 2016 for the stock unit is a long time ago in consumer electronics

      @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?

      Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
