Finally collected my E89 Z4 Sdrive 2.3i

Collected the car on Tuesday and I am very happy with it. The trip home (roof down) was on a mix of roads so it gave me chance to test it's abilities. My test drive, the week before, was as a passenger even though the owner offered to let me take the car with my wife for a spin!
I was surprised by the performance. If you cruise at 2500 rpm it is a very smooth civilised quiet car, but drop it a gear and floor the right pedal and it becomes a hooligan and keeps pulling faster as you near the red line. It is almost like a turbo engined car spooling up the boost the faster you thrash it.
Considering it is a normally aspirated 6 I was surprised there wasn't more low down torque, but the soundtrack when you give it some does become addictive 😬

Do re-maps change anthing to the torque curve ? I have read there is about 20-30 bhp gain to be had. Has anyone gone the route of OBD chip tuning on this engine? I have seen a system that uses a module that plugs into the OBD socket and the chip can be turned on or off by a bluetooth app on your phone.

My only gripes are the way the electronic handbrake works and the none functionality of the phone buttons on the steering wheel and radio.
My everday Vauxhall has an electronic handbrake which self releases when you set off. The BMW system doesn't so I embarrassed my self at the first set of lights when back in my home town by stalling the engine when the lights changed as the handbrake was still on.....Doh! Is there any reason why BMW haven't made them self release?
Obviously the car didn't have bluetooth phone capability specified when new...a bit mean on a car costing around £30k when new???? I am going to fit a 3rd party 10.1 inch Android media screen in place of the top cubby hole, so this should fix this one and also add the Sat Nav that I was looking for in the spec of the car when searching.
Just hope we get summer back soon for some more roof down driving action😁

Hi and welcome to the forum.
Well done with a photo on your first post, looks like you’ve got a plan for the android screen/satnav upgrade. Let’s hope the sun keeps shining and you can enjoy plenty of top down motoring, is this a daily or a weekend toy, and definitely the right decision getting a 6 pot, I don’t think there is much to be gained from a remap.
 
Hi, your 23i should be a reliable car with its 2.5litre n52 engine - just be prepared to fit a new electronic water pump as they can fail without warning occasionally!
You’ll get used to the ebrake, you put it on & you take it off - simples :thumbsup:

Hi and welcome aboard. :thumbsup:

Your car looks great, and congratulations on getting a straight 6 in the engine bay!

Water pump life seems vey variable. My 1st E86 needed one after 10 years and 60K miles, but my 2nd was on 91K and 13 years when I sold it with the original pump. The main issue is inconvenience as the engine gets too hot in about a mile, and the new pumps cost about £300.

But for now just enjoy using those lower gears and getting the revs up. :driving:
 
Hello and welcome to the site.
Nice for a newbie to get a picture up straight away and you have a tidy looking motor.
Now let the spending and modding begin lol
 
Welcome to the forum and joy of the NA straight 6 engine. It's all about the top end and listening to it sing. :D :driving: :thumbsup:

Torque is for rep mobiles and heavy cars on motorways. :wink:
 
I retired in February so it's a late retirement present and a fun car for weekends away and touring about before we're both too old to get in and out of one. :wink: My wife had her first go in it at the weekend and got on ok but a wind deflector is first on the shopping list for her🤯 Don't think the rev counter went above 2500rpm so she didn't know what it was capable of. Showed her what happens when you get above 4000rpm on the way back! It just becomes addictive that 6 pot roar😄👍
