Just came across this thread. We've had a e90 335 in the family along side out 2.2 Civic for 3 years.
I use to have a DC2 Integra R, and than 350Z. As much as I hate to say it the 335i is by car the best all round car I've owned/driven. It makes the Z feel bloated/under powered, and makes the DC2 feel too compromised for daily use...
A word of warning about modding the 335 though,..it's endless and far too addictive.
I changed my angle eyes a while a go, the install is not hard at all, took me 1 hr in all, mine a while ago with some LED bulbs. Am quite happy with them though, definitely a better look compared to yellow OEM bulbs.
Ive also done things like upgrade the sat Nav from the old CCC unit to the new CIC
Went from this..
But those are all just minor mods really, the main costs has been the suspension and powertrain.
Now running, AFE sealed intake, AR catted downpipes, and Forge intercooler, Procede tune with boost limit set a 14 PSI, Tesco super unleaded (99Ron), about 29 degrees ambient temp, the car made 380 bhp and 390 lbs at the crank.
Was quite happy they dyno bit it was only later on at home I realised the shape of the power curve was very odd...it suggest all the power arrives in one chunk which is not the case from daily driving.
Just to reassure my self, had another look at my logged runs, and am pretty sure the guy doing the dyno must have had wheel spin at 3000-4000 rpm, since on my logged runs by 4000 rpm the boost is already nearly at 14 psi!! Looking at other 335i dynos graphs it appears maximum torque is usually around 4000 rpm, wheres on my dyno graph at 4000 rpm the car is making hardly any torque/power, so wheel spin seems like the most feasible explanation . So I guess the ture maximum torque is probably over 400 ft-ibs!! and BHP must be close to 400!!:scare:
All the power is ofcourse pointless without control...so also have added
Bird B3 suspension kit
Ebiach Antiroll bars
EBC yellowstuff pads
M3 subframe bushes.
I've now finally finished modding the 335 (no money spent on mods in the last 6 months). The car handles as well as my only DC2 Teg, and is just as quick as an E90 M3 in a straight line
As I said the 335 is by far the best car I've owned....but it is not reliable, have spent nearly £2k on repairs (water pump, fuel pump, coils, autobox transmissions leak) this year. Also don't get your OBD port secured...Google BMW theft OBD and your see what am talking about.
But enjoy your 335s!!
