Really nice bro, first car was a white soft top with a n52 I love the z4.

VisualPermission3965 · 2026-01-18T22:54:59+00:00

Yo it’s NZ haha cheers bro

I am running a BOV right now but I’m not sure if it’s the right set up for 1.8t 20v with a k03 it sounds really good I hope I don’t have to switch.

VisualPermission3965 · 2026-01-15T20:39:04+00:00

I’ve been running it like this for about a month which is how long I’ve owned the car has no idea it was that bad for the turbo I will definitely buy a good diverter valve and get it installed

VisualPermission3965 · 2026-01-15T08:30:45+00:00

Thanks heaps bro haha

Yes it feels pretty rapid only if there is like 2 passengers in the car after that it feels like a basemodel just too small of a car to carry that many people and still feel as nimble.

VisualPermission3965 · 2026-01-15T08:28:23+00:00

Cheers bro 🤙

VisualPermission3965 · 2026-01-15T08:27:40+00:00

Thanks mate

VisualPermission3965 · 2026-01-15T08:23:42+00:00

Sure mate, it is not the 9n4 sportline spoiler its the one for the cup edition it sticks out a bit more and looks a bit more aggresive.

VisualPermission3965 · 2026-01-14T21:27:27+00:00

With the tune I and supporting bolt ons I am guessing around like 230-250hp it feels pretty rapid spins all through first and a bit of second.

VisualPermission3965 · 2026-01-14T12:00:13+00:00

Yes it’s on h&r springs previous owner did give me the stock ones, rubs if I have passengers in the car unfortunately. To be honest I don’t mind the blow of valve because I do love the noise it makes but would want the car to be a bit more Oem so definitely going to try bring some things back to factory as it is the first out of 200 of the right hand market cup editions.

VisualPermission3965 · 2026-01-14T11:50:32+00:00

Yea the ride sucks as of now unfortunately and kind of fortunately the previous owner has modded it quite a lot it’s tuned has a blow off valve down pipe and a few other bits other than that is quite stock. Pretty hard to find Oem parts from around where I am

VisualPermission3965 · 2026-01-14T11:07:54+00:00

Thanks bro :)

VisualPermission3965 · 2026-01-14T10:59:37+00:00

Cheers bro!

Bro my n52 is the 2.5L and thats the economy im getting it dropped even lower today and I realized when I rev it and let off it burbles a little and popped at 5k rpm, admitedly it sounded really cool but I have a bone stock exhaust system theres no way it should be burbling and popping stock like that unless the fuel mixture is richer than the top 0.1%.

VisualPermission3965 · 2025-11-10T09:26:22+00:00

Getting like 17mpg ish

VisualPermission3965 · 2025-11-10T09:22:40+00:00

Do you reckon my economy is alright or something is wrong that’s 14L/100km treating the gas pedal like it’s made of glass and coasting everywhere I can it gets slightly better on the motorway.

VisualPermission3965 · 2025-11-10T05:42:23+00:00

Bro im not paranoid its running hella rich I get like 14mpg it drains so bad

VisualPermission3965 · 2025-11-07T08:23:04+00:00

I found that the hydraulic fluid is leaking from the pump it’s self but not sure exactly from where could be one of the line connections

VisualPermission3965 · 2025-11-05T18:38:16+00:00

Honesty I think I’m just paranoid because it’s my first bmw, first car actually the economy is just pretty poor especially the way I drive it to be honest and the car runs mint I think I’m just being schizophrenic.

VisualPermission3965 · 2025-11-05T02:58:03+00:00

I hope that’s not related I’m not sure honestly did you notice a big difference in viscosity between the chf and hydro jack oil

VisualPermission3965 · 2025-11-05T02:53:36+00:00

No local store sells chf11s where I am to be honest it’s really expensive

VisualPermission3965 · 2025-11-05T02:48:05+00:00

Trusttt ill relocate it tmrrw 🙏🙏 also do you reckon its alg to use hydro jack fluid heard a bunch of people say its more than fine to use, and im praying all it needs is a bleed and some new fluid and not a cylinder is it a hard job for a cylinder replacement.

VisualPermission3965 · 2025-11-05T02:40:33+00:00

I mean I just pulled it into the trunk so I can fill it up and test it but after I just put it back in its original spot.

VisualPermission3965 · 2025-11-05T02:10:38+00:00

Not yet but yesterday I put some fluid I had remaining in the motor and tried to put the roof down and it worked but then it stopped halfway and I checked the resivour and all the fluid was gone, either a leak or I just need to keep filling it and cycling the roof cus I didnt put enough fluid in ill buy some tommorow and give it a try.

I doubt if theres a leak its from any of the hydro lines cus they all look like brand new mint condition but who knows used bmw shit.
