So I thought I'd start to document my jourmey on taking a bog stock 35is to the next level.
Having done the journey with a AY E89 20i Msport Auto, some parts of this journey will be very similar.
However, as I have been on this journey before, in some cases, for the sake of change and variety I've altered /sourced differnt parts.
So the 2011 35is with 50k miles and 4 previous owners came to me after lurking on various sites watching the inflated sales price come down from £23k to around £19k.
The car had a part BMW , part low grade Indy service history and looked like it had been garaged most of its life and not used hard.
It was fairly 'fully loaded' with most UK options, Idrive, extended USB/Blutooth, electrically heated/adjustable eats, PDC, 14 speaker DSP HiFi etc
First thing was to swap the Zito 935s running GY Asy 5 235/40 18 and 265/35 18 from the 20o to the 35is.
Ride and handling much better..still very disappointed in the adaptive suspension especially 2 up.
Popped in some high intensity LEDS in the DRLs and fitted an offical set of BMW black grills.
Next a walnut blast to take out about 1mm of very hardened carbon on the intake ports, fresh NGK 1 stage colder plugs and fresh air filter.
Then a baseline dyno run (before which number 2 coil went south), then a MHD stage 1+ re-map by myself and a second dyno run..moving from around 345BHP to 390 BHP and torque up from 500 to 550 nm (UK tends to use crank BHP and I've used this dyno a lot)
