I own a 318 ci with the M44 engine unit, and tiptronic gearbox. The cars perfect bar a lack of acceleration from 0-30mph which leaves me struggling to pull out in time from junctions and feeder roads onto motorways. The manual lists a 0-60 time of 12.0sec for the tiptronic which is pretty much the same as the 79hp corolla I had previously, any way to make it 10sec or less, without actually modifying it or is that the only option avail? Any help will be much appreciated.
Thanks for the reply. I have the M44 unit, not the M43. How hard is it to fit this to my engine? I've already got the car superchipped, the engine still struggles though. I was looking to get the power up to 180hp or so. What do you think is my best bet?
You could buy a 325i, that would get you up to 180hp. :-)
What's the base hp of the M44? Short of super/turbo, most mods seem to generate a max of 20-30hp (CAI + chip + exhaust + pulleys). Is 180 a realistic number with this car?
Hootie, the base hp is 118hp, with the chip it's now around 131-133hp. It still takes 11sec to get to 60, the engine races but goes nowhere. I'd be happy with a bit more power, say 155hp max.

fitting for the FSE PBV, you will need to have the knowledge of fitting fuel pipes in the engine bay, quite easy in fact. it won't increase the hp, but it will help for the initial acceleration by pressuring up the fuel pressure, that means quicker throttle. data said 1.7 times more respondsive.
may i ask which year is your 318ci?
because there were only two engines being used on e46 318ci, M43 (1.9) and N42 (2.0).
Storme, its has the same engine fitted as your one, and the reason why mine takes so long to get to sixty is because of the auto gearbox, the operators manual lists it at 12.0 sec (0-100km/h or 62mph). Does yours have a tiptronic? Also the car is fitted with a lot of extras. I didn't think this mattered till I had the car weighed (undergoing my countries national car test)with half a tank and no luggage, no passenger, driver or personal items in it and it came in at 1450kg +. They would have spotted any fuel or engine problems so there's nothing wrong there.
Mattadav it has the 1.9litre engine, 118hp. now with the chip it's 130+ but still slow. :
also i am having my disa valve and crankcase breather diaphram changed at the weekend...i have been told that when it is replaced..there wont be the iniatial slow responce,,,then the boom (like a turbo) this indicated a worn butterfly valve in the disa valve...i will post again and let you know if it is any good

it is already really gd for you to get to 130 bps, umm try to get a weight lift for your car, like fiberglass bonnet or removing the spare tire?
between, where did you get your car chipped? and what kind of programme was that?

is there any aftermarket disa valve or crankcase breather out there for 318ci?
if you are just replacing them, i would say repairing them because the old ones were worn, i don't think that will help with the initial slow response that came with the 318ci, i might be wrong but please explain more, im quite interested into this topic
I purchased the superchip from superchips.co.uk. It was pretty inexpensive(450euro) and it only took half an hour. It gave me 14-15hp extra, with 15% increase in torque also. They have workshops in just about every country in Europe. With the chip installed, fuel economy has improved, I'm getting 65miles city driving out of less than a quarter of a tank. Furthermore, my warranty isn't affected by the chip being installed either. I have nothing but praise for the thing. Check out the website, they seem to be the only company that are backed by every established motor garage.
Yeah, changing the diff. will give you up to 15% gain in power/torque.
Custom made, limited slip would cost you in America few grand !
