im good,im good.........so used to a sixer now a 4 potter doesnt give me the oomph i need la...........but this 4 potter is quite good for top speed tho........tried slightly pass 190 kiloes and feels like it has samore meat to give but not much more i guess!!Originally posted by Zoggee@Aug 29 2005, 06:21 AM
oi sideways...cipek..!!!
i cant outrun them on an open highway for sure cos even if u put a 16 year old girl in the car n ask her to just step on it she would outrun me on a highway for sure mah............dats a no brainer man!!
put a good driver in a holden n ask him to keep up with me on the dandenong hills would be a very different case!!there no cops for sure unless an accident happened n they come to pick up wats left of the corpse n cars!!
watever it is just dont race on any public roads which may involve other innocent people..............if wan ti try try know ur limits n dont ever be stupid n show off is best!!
i think dats the legal age here age neways.............heh heh nola just trying to explain how easy it is to just put the pedal to the metal mah!!Originally posted by koryong@Aug 31 2005, 02:49 AM
You're into 16-year olds now, are you ?
16 year olds here look 25 or more man so i have to find younger ones if i wana a 20 year old hehehe!!

you feel you can extract more from a m42..??? B) wah.. automotive engineering student now speaking like bmw enjiniar leh.. :blush:
play with the breather in and out and the diff first la... after that ...who knows... :blush:
even at stock oso the m42 is considered fast and reliable la..

Mr sideways.... lama tak jumpa.... last time I met you was with loneranger and whl at bangsar....
anyways for your info, the following is from a guy named stuart mchenry from the r3vlimited forum :
Modifying the M42 318iS Author: Stuart McHenry
This is a compilation of things that are necessary to get real performance out of the M42 engine that you use in a street/auto-x/mild track use car. These are items that will improve the cars performance and not sacrifice any low-end torque, which you want for street driving. These are all pretty much "bolt-on" mods, using the engines factory internals. If you want your 318iS to really fly on the street, these are the things you need to do:
Computer chip - This is a very basic and inexpensive modification for your car. Chips usually run about $200-$300 and are very easy to install. A chip on a stock M42 will bump the horsepower to about 145 (from 135) at the peak. The low-end torque is increased as well to improve everyday drivability. Though the real improvement comes at the top end; the chip widely increases the power band on the M42, from 4600-6000 to 4500-6700. I recommend Jim Conforti chips, as they are unarguably the best on the market for this motor, at a good price as well. On a side note, you will find the M42 makes a very distinctive "howl" from 6700-7200 rpm that reminds you that you’re driving an honest-to-God BMW.
Flywheel - A major problem with the M42 was that it had BMW’s 'dual-mass’ flywheel; yes, it weighs almost twice as much as a 325i flywheel (as the name would suggest), at 28.5 pounds. This is a big problem and absolutely kills 1st and 2nd gear acceleration. Ever wondered why your 318iS’s 0-60 was so slow? Well, the flywheel is one of the reasons. There are 3 options to fix this: 1) use a 325i flywheel/clutch or 2) buy an aluminum flywheel for your M42's clutch, and 3) an aluminum flywheel for using the 325i clutch. Buying an aluminum flywheel for the M42 runs about $500-700 but is very light, and requires no modification to be fitted. M42 aluminum flywheels are about 12 pounds, and 325i aluminum fly's are about 8 pounds. The 325i flywheel requires a few other modifications to be fitted in the 318iS. Here’s what you need: 325i flywheel, 325i clutch, 325i pressure plate, 325i drive-pinion for the starter motor, and a ‘78-’83 323 throw-out bearing. Replace all these with the 318iS parts and it bolts right together. After all is said and done, your 318iS will have a LOT better acceleration in the first few gears, and deceleration will take place much quicker, which helps on the street and in the auto-x.
Rear end gear - The 318iS is equipped with a 4.10 limited slip from the factory, but you can do better. The desired gears out there are the 4.27 and the 4.45. You will find the 4.27 in E30 318i convertible 5 speed’s and the 4.45 is in E36 318i automatics. The 4.45 is a wicked, wicked street gear but will stick your RPM way up there on the highway. The 4.27 is a good compromise of performance and everyday use. It should be known that to make a 4.45 work, you have to swap the gearset into your E30’s differential, or find an automatic 318ti, which has a 4.45 and also has trailing arm rear suspension! So the E36 318ti 4.45 bolts right onto an E30, though finding an automatic 318ti with LSD may be difficult.
Adjust the cam timing - You know how on the E30 M3 you have to buy a $300 kit with adjustable cam sprockets to tune your cam timing? Not on the 318iS! The M42 is equipped with tunable cam sprockets from the factory. So pull your Cosmoline covered valve cover off and with the proper tools you can tweak your intake and exhaust cams up to 6 degrees +/- to provide more top end horsepower or more low end torque. See, you don’t have to blow a grand on a set of Schrick cams to make your M42’s cams a little hotter. The best setup is to adjust the intake cam to 5 degrees (advanced) and leave the exhaust cam alone. I would recommend having a shop do this work.
Muffler - The 318iS is equipped with a very free flowing exhaust manifold and center section with 2.25" stainless piping. The bottleneck in the system is the muffler. Thee are a few options for this. The first is a cat-back system, which replaces the piping and boxes behind the catalytic converter. Supersprint makes an excellent cat-back system that runs about $400. You can also simply replace the muffler. There are a variety of mufflers on the market but there is one that is very inexpensive, sounds great (not too loud, but throaty), and fits an E30 very well - it is made by Walker-Dynamax and is called the "Super-Turbo" muffler. It is available from Summit Racing at the price of about $40. We have had great success with these mufflers, and even use them in 3" size on our E30/S50 cars.
Intake system - The 318iS stock airbox works well, but a cone filter setup works better, but only if you have a well-built heatshield! Get a large K&N setup with the AFM adapter and all. Go to Home Depot, buy some Reflectex and build a "cool-air" system by cutting and fitting a heatshield. It is worth it in the end. While you are working on the intake, get the secondary plate of your throttle-body bored out 3mm to 57mm. This will make a difference.
Summary: You will find that with a little time, a little cash, and a little elbow grease, you can tune your 318iS to really perform. William Zubrick's 318is with a properly built intake, Supersprint cat-back, and Jim Conforti chip puts 131hp to the wheels on a chassis dynomometer. Enjoy!
Note - the above is kind of US-centric - some stuff or specs may differ or not be available here.
While the following is from a forummer..... was it kev? :
1. Electric fan - use the one from an e36 as it is plug and play (some wiring required though) to replace your fan clutch to reduce the mechanical load on your engine. Cost: RM 250 for the electric fan from chop shop and RM 150 for the wiring.
2. Lighten your flywheel - already covered above
3. Upgrade your injectors: Go to the chop shop and look for the injectors from an E34 520i 24valve. Better flow rate and finer spray pattern. Expect to pay RM 150-200. Plug and play, just need to retune your CO to 1.5.
4. Performance chip: already covered above
5. Piggy back ECU: one up from the chip as you will have full variable control over your fuel map and ingnition timing.
6. MAF conversion:Mass Air Flow meter, to replace you AFM(air flow meter), this is to be done with no.5 as you need the piggyback ECU to decode the signals from the MAF to your existing ECU.
7. Forced induction: the holy grail.......supercharge or turbocharge your M40 and give the six-potters a run for their money!
If all else fails.... tukar kereta terus...... DD kata kereta kat oz murah2 so shouldnt be too much a problem :lol:

I'm sure dude...... Malaysia boleh!
But these are the most common ones I think .... whats not listed here is a stroker kit (2.0 or 2.1 .... not sure) used to be avaiable but not anymore..... its also mainly for the M42 in the E30 318iS..... should still be applicable to the ones plonked into the E36 318s tho......

whoa... Jipster very helpful la.. :wink: you covered almost everything la.
very similar to my mods...only that i have two extra pistons.. sigh..extre pistons means extra moolah on mods.. :beaten: and very little gain in power wise.
but as i say...as for stock. the enjin is enuf liao. :yes:
