 Topic: E30 318is vs E36 318is
Posted: 05-November-2003 at 15:40 |
Hello.. just purchased a H plate 318is.. clean bodywork, 115k on clock with all original usual refinements for £1000... Is that a fair deal? Os did i pay over the odds?
And which 318is is quicker/better? The E30 or E36?

One more question... is it normal for the car never to heat up, i mean the temp needle never goes much further than the blue bit... but if stuck in traffic, eventually the needle willslowly move towards the centre as the engine is heatin up and stay there, but i've never seen it go past it? Is there something wrong with the temp gauge ? Or all normal?

I would say the E36 is quicker as I think it has more power, but it weights more!!
On the temp thing, you need a new thermostat. about £5-10. Mine was £10 from BMW for the 328 - not sure if its the same type of stat for yours.

I reckon an E30 318IS is probably quicker than an E36. The E36 weighs quite a bit more and only has a few more bhp. I haven't driven either car but would say the the E30 is the better car, more fun to drive and more of a classic.

I have an E36. The first BM I have owned. It is not blisteringly quick , but then again I never expected it to be being a 318, having said that once over 3500 rpm the engine is more than good enough for what I need and is extremely responsive. The main thing I noticed when I first drove the car is the handling. With the m-tech set up it sticks to the road like its on rails , I can not fault it,mind you I havent had a good spin in the wet yet. I beleive the BHP for the E36 is 140 with a top max speed of 133 mph. Not sure about th E36 data. Overall the E36 is a real pleasure to drive.

In the E36 model, were the earlier models less powerful?
I thought originally the 318 was about 115-120bhp then later it went to 140bhp

I'm not putting the e36 down.. i think they are a brilliant motor, but the 318is engine doesnt do the body any justice... in that shape you need a 2.5/2.8... or the ultimate the M3... but anything below.. ie.. 2.0 or 1.9 is just not powerful enough..
I mean i drive from london to swindon a couple of times a week... bombing it down the M4, and i quiet a few e36's just get left behind... ok there top speeds may be higher... but general driving wise they have to work hard to keep up...
so DAVE28, you reckon its the thermostat? does it mean it's showing a lower temp than it really is? as i said, if im stuck in traffic the temp gauge evtually moves to the middle, but than when traffic flowing again on motorway the temp needles moves back nearer to the blue side...

The E36 318is was originally a 1.8 16v, but as it seemed a little underpowered, it was increased in size to 1.9.. so i think the earlier models of the e36 must have the same engine as the e30..

The E30 318iS has the M42 engine which was carried over into the E36 when the iS version was released. Later, after the launch of the Z3 the M44 engine with increased capacity (1900cc) was used in the iS.
I'm probably biased but the overall speed of the car isn't as important as the fun you have. The E30, altho lighter, will have the lower top speed because the E30's poor aerodynamics compared to the E36 with either the M42 or M44 engine. Performance wise both cars with the M42: think the E30 will be marginally quicker off the line but the later M44 should be just quicker. I've tried to follow a m8 with the M44 and can't keep up in a straight line (but he does have a chip and air filter compared to my standard car).
Also i find the E30 a more organic experience as you have to work harder when attacking the twisties but in the end it's more fun, plus sideways seems to be more accessable in the E30.

the E30 318iS is the quicker/funner (made up word) car, the E36 has slightly more bhp but weight quite a bit more.

The 318i is 118bhp and 318iS is 140bhp, nearly the power of the 320i but a 4pot more rev happy engine.

Basically what happens is with age the stat can warp the shaft inside so it isn't straight thus not closing properly. When the engine is cold the stat should be shut, when warm it opens and closes to let cool water thru, but if it is stuck open slightly it will let cool water thru all the time, so when driving at speed it will cool the engine off more than it should. When stationary the rad isn't getting any air through (at least not as much as driving) then it will warm up and then the engine will warm up (to the middle on the guage).
Mine did this - took longer to warm up and on the Motorway it went to the blue part on the guage, then in traffic it went to half way. Took the stat out and you could see it was stuck open, not loads but enough to cool the engine too much, especially when the weather is colder.
Change it and it will stay in the middle and also warm up quicker - saving money in fuel!!

You'll need a thermostat, housing gasket and fresh lot of antifreeze would be a good idea while your at it, since the winter is coming.

Do you mean the antifreeze?
To change the thermo you need to remove some of the coolant and bleed the system so to me you might as well empty the whole lot and only bleed the system once.
It's fairly easy but you need lots of patience bleeding the system. Also, there is only one manual that specifically covers the E30 318iS and that's the Chilton (USA version of Haynes and not great IMHO) other than that your best bet is the Bentley manual for general E30 info.

I've got the Haynes E30 for body work etc. Would the E36 manual do for the M42 engine?

Is about the right price, if anything you got a good deal if engine/body is sound |
