Ah ok then, the fpr has a gauge if that's what you mean I think it sits on 4 -5 psi I don't know about them tho

they shouldnt be tampered with unless you have a wide band oxy sensor ect

But the base fuel pressure should be around 3.5 bar. and rise under load.

if its 4 or 5 bar (big difference) than its probably squirting 10-20% more fuel into the car.

you have 2 options. replace the reg with the stock unit or wind the pressure back. do this at your own risk as you also have the potentual to lean the motor out by doing this as well. if it was my car id have a play with it and see.

Hey autumn I have a safc2 for sale, 250 delivered as new condition with all wiring etc. This will allow you to tune your fuelling and run a z32.

Also if your relying on a drift brand air fuel ratio gauge to tell you what the cars tune is like, your headed in the wrong direction. One of those gauges won't tell you much at all, you need a proper wideband a/f monitor.

I've got some interesting problems with my R33.

Problem #1 When I brake the pedal goes straight to the floor, then upon having a 2nd stab at the brakes it'll be fine, good feel and pulls up fine. Giving the brake a left foot chicken tap before braking doesn't seem to help.

Problem #2 with the brakes, when I'm doing a burn out and having the left foot on the brake the pedal get really hard and pushes my foot off the brake and eventually the brakes stop working and the car will just go forward. (obviously doesn't want to do skids lol)

Problem #3 Steering is really really heavy sometimes, all morning at drift practice it was f**king and the car didn't self steer at all, not when sliding, not when transitioning, not when crusing around the corners in the no drift part of the track, you turn, the wheel will stay at that angle until you change it, and it's so heavy only the hulk can steer it. This problem randomly went away in the afternoon of the drift festival but came back when unloading the car off the trailer. Car is a NA conversion so it doesn't have HICAS.

Suggestions?

I'm thinking the braking problems could be because the NA Brake booster doesn't like being turboed?

probabaly silly question, but have you checked and bled the powersteering fluid?

Checked yes, Bled no, that's this weekends job.

that sounds just like my brake problem.

you can pump them up to hard. Then as soon as you take your foot off its soft as shit.

If I pump mine up it'll stay pumped.

Yours sounds like leaky lines. Had that problem in old Suby wagon.

ive bled them but still no go, did it again yesterday, might look into some braided lines or something :)

Are you doing it right? I remember trying to do it on my old motorbike and constantly f**king it up but not knowing any better.

whats the right way?

i do it like this

pump the pedal till its hard then get who ever to open the caliper nipple then they close the nipple once the pedal has hit the floor

is that the right way lol

1# bleed your brakes

2# you need to have a 1 way valve between the booster, and the plenum. You either don't have one, or it's stuffed (pretty commen), one way valve will fix your problems. But remeber, the booster can only hold so much vacume, so depending on the lenth of time your on the brakes, your pedal will get harder.

3# could be your rack, and/or pump.

    • 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
    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @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
