I got the 28i but apparently an 18i and 20i will map to 260bhp. But the 28i will map to nearer 280-290bhp. Apparently they're all the same so no idea why the 28i produces more power when mapped.

I think the 28i has bigger brakes, if the 18i/20i has worse brakes than the 28i I'd definitely recommend upgrading them if you're planning on remapping.
Evolve can get the 20i to this level & a decat downpipe can put another 20bhp on top...

But a 28i will map to more than that without the decat / dp and over 300bhp with it.

I personally wouldn't want to be driving my 28i with brakes worse than what it has.

If you can find a 28i then get one.
Eh? You said the 20i maps to 260 & I've shown the evolve tune goes to almost 280 which is the figure you said the 28i can reach?
With a downpipe the 20i would be around 300bhp, can't see the point of paying thousands more for the 28i for a couple of horsepower?

I'm the proud owner of an 18i and I'm just waiting for the opportunity to remap. I don't have any fancy spec and I really don't care about big wheels and non-RFT's. Get what you want the 18i and 20i are the same under the skin other than the hp figure. :thumbsup: :D

I also notice you can't seem to get a 1.8i MSport either

OK, so lloks like I probable need to keep loking for 2.0i and above
Another new Z owner here..
I just got an 18i with exaclty the same intentions.. Mine is an MSport, so there are some out there :thumbsup:
There's nothing wrong with the ride quality at all: mine is on 19s and runflats. It all depends what you're used to.. My last car was a JCW Mini that was lowered a bit. The Z feels like wafting along in a wallowy limo compared to that :D :D

Keep on autotrader and set the max engine size to 2.0.. depending on your budget as well of course :thumbsup:

Sorry Rob, I only saw the 265bhp figure!

Engine aside, what other differences are there between the 20i and 28i? Brakes? Suspension? Anything else?

No worries, they gave my car 3 full power pulls on the rolling road post mapping & it increased in power each time as the ecu fine tuned the engine-they said it would carry on improving over the next few hundred miles :P
as far as I know it's just the front brakes have larger discs?

Seen this, mileage is high for year but reflected in its price but great spec and colour combo

There is a valid thought process to make an 18i or 20i into an real wolf in Sheeps clothing.

Remap
Supersport downpipes
Wagner intercooler
Bmw performance break kit
Plus suspension
M3 trailing arms

Estimated cost about 2,500 to make an 18i to an 35i killer :fuelfire: :rofl:

1.8i or 2.0i MSport 2014

Hi the 2.8i has 30mm bigger front discs.

Various tuners can get the 18/2.0/2.8 to over 260bhp with remaps

The common issue in all cases is thermo dynamic stress....all the engines have identical cooling systems and induction systems.

Also although on paper 265bhp is less than 280bhp on the road many other factors mask those issues, type of gearbox, driver technique, sport mode vs comfort etc etc

So a 1.8 debadged and ECU mapped is more driven by the goodies on board.

The cited design expectation for all these N20 engines is 150k miles.

There is an exponential decay factor to life expectancy based on how often/how long these engines operate over 280bhp / 320 ft lb torque

As usual there is a spread of probabilities of when and if an engine will let go over these limits.

The usual I smoke 60 woodbines a day and it doesn't do me any harm.

The I.8inhas some cosmetic and minor equipment changes (brain damaged) as we in marketing call it..if you can live with those or have upgrades for these then the 1.8i is a no brainier IMHO

Also for reference all the 4 pots are around 70kg lighter than the 6 pots with the engine weight nicely behind the front axle.

The massive reduction in polar moment of inertia wii improve handling and the reduction in mass will improve initial acceleration by around 5%

The spec you show with adaptive m sport suspension with 296 should yield good handling and comfort if you have non run flat tyres...

All IMHO... 8)

Thanks for great bit of info

How good is the adaptive suspension i.e. Comparison to the std m sport suspension?

It seems to be more prone to leaks than the standard set up & bmw charge a ludicrous amount per damper of over £600 I've heard :cry:
