0-60 in 7 seconds is slow as hell. Brisk for a family car in 1992 maybe.....

Have you seen, figures for the 335d which has been around for a few years.

its not even that good for 1992. rwd cosworths were 5.9 in 1989 with only 33bhp more than an e30 325. :D

E30 325s are near enough 7 aren't they? I suppose the E36 is a tad heavier though but I'd have thought the 328i would have been quicker than that?

My Alpina has a 0-60 time that is under 7 sec IIRC ( I think 6.5 - 6.8 like the M3 ). How heavy is an e36?

Who cares.

There are plenty of fleet motors that are far quicker to the ton than the old e30, e36 etc.

That puts it into context doesn't it. Makes me think when I see an E36 sporting the same 316i badge as mine! :mad:

no disrepect to your 328 mate intended. I went in Pauls e36 ACS at the Oxford meet and it was awsome. If I ever get the cash one day I want a B3/6 e36 as I love the Alpina look.

Also let's face it the e36 is a much safer car and hence the weight.

Go onto the Alpina register and take a look.

My Alpina had a full engine transplant for it's conversion. It's a 195bhp car that is light. No willy waving figures it's fact. If we are at a meet together I will be happy to take you out in it. To qoute Total BMW magazine when my actual car was in it they said it was one if the most savage Alpinas built! Also typical Alpina madness was the top speed is higher than the Speedo goes too LOL.

Even a 325i with 171bhp could do around 7.3 and a sports close ratio would take it down to 7 secs.

A standard iS is not a match for a 325iS.

Once tuned, things become more apparent the 318iS weighs 2602lb and the 325iS 2865lbs according to this website: http://e30world.com/specifications/BMW-E30-specs-table, that's a whopping 263lbs, if you think that won't change a cars handling characteristics (especially if it's hanging over the front wheels).... you're very wrong.

With a sensibly applied (equal) budget a 318is will never out-drag it's bigger brother, on normal roads I doubt it would fair much better but it would be much closer.

On a track where momentum, grip and balance are most important, I think a tuned 318iS on a good set of ITBs would be quicker than a b25 on the same budget due to the weight displacement and engine position would give it an advantage. I follow hill climb here in the U.K and there are two main camps, high revving n/a and big power V8/turbo.

Power is not everything when racing at competitive levels, the way your car responds to your driving is far more important. For instance norris designs 900-1000 bhp short wheel base evo is not winning against the 700-800 bhp RCM impreza, in the U.K time attack this year.

it would be interesting to see dyno graphs for standard M42 vs M20B25, since how an engine makes power and where are important factors in how quick a car is at speed, since 170bhp is no good if it peaks at 5000rpm and falls to 150bhp at the redline.

I don't even own an E30 atm, i'm not bias, infact at the end of the day reliability is pretty much the most important factor since it all means sod all if you don't finish the race!

I thought all 318is cars had ITBs? or is it just the ten white ones?
Im sure with a K&N and some eyebrows you can get the 0-60 down to around 4.6secs iirc.

It says in my lit that the 328 does 0-60 in 6.7 secs, which i think is quite quick given the weight.
Im sure if he did a few runs the time would vary a lot anyway as its hard to determine .2 of a second without propper gear.
Best to video it and time the vid.

And 911s were 4.9 back in the 70s. (yes i realise it has no relevance as its a sportscar, but i need to mention 911s every 10 posts or i start rocking)

The 0-60 (or 0-100) time of any car is determined by a combination of power, torque, weight and gearing.
Even a fairly modestly powered car with low weight can be made to accelerate quickly from a standstill.

On the road, though (or track), the driveability or in-gear acceleration is the thing that makes it feel fast...
30-50 or 50-70 is far more often used than 0-60. If your car has plenty of torque, then this can be accomplished without dropping a gear and will therefore feel faster.

I would agree with Kit-L that a lighter and almost as powerful car on the track should outperform a heavier one. This is one of the reasons that the E30 M3 was successful...

Lower placed concentric weight displacement and the engine behind the front wheels, play reasonably important roles as well, which is where the sixers fall down... but this can be compensated by adjusting suspension setup, because if driven/setup incorrectly it can result in understeer at high speed.

Same, my step dads old E39 528i felt pretty quick and that was far heavier than your dirty six.

it depends what figures you choose to quote. ive looked up a random site and found totally different figures.
318is...1200kg... 2646lbs... 139bhp...115bhp per ton
325... 2 door...1148kg... 2529lbs...171bhp...148bhp per ton
325...4 door...1209kg... 2665lbs...171bhp...141bhp per ton
whatever figures you use there wont be a 263lb real life weight difference between a 318is and a 325.
just for comparison my touring is 1320kg...2904lbs...330bhp...250bhp per ton and 52/48% weight distribution winkeye

I've got a 340 ft/lb impreza type ra and I notice the difference when someone is in the car, mind you my suspension set up is highly tuned.

I'm sorry but 263lbs is allot of weight.

Which website did you get your figures off, i'm assuming an E30 enthusiast website (where I got mine) would be bang on.

I would say the factory supplied handbook in all E30's would be the most acurrate in terms of weight. A 2dr 325i is 1180kg.

Perfomace figures can vary widely proof in the fact that contemorary road testers got better times than the factory figures.

I ceremoniously minced a std type ra with my std 325i .. this was over a 6 mile dash, we both had a passenger onboard, which kept things in check (and contributed a witness to the event!)

We parked up & he asked if my rusty cirrus blau 160k 325i had a 3.0l fitted.. I think I just smirked and screeched off showcasing the full vocal range of the m20 :D

Power is nothing without control, an iS will out-brake & out-nimble a 325i. I used left foot braking a lot in the 325i - the 20yr old bushes like it that way.

Momentous occasions, either way, a rusty 325i is still rapido & with bilsteins & eibachs, makes for a wolf in sheeps clothing

down a twisty ass road the iS has JUST enough in it enough to out pace a type R.. princely where the type R hasn't the chance to hit its cam.. by the time the straight came, I was done :D

An old thread but..
The funny thing was that shortly after that crash I happened to visit a new forum and lo and behold there was a guy with MR2 in his username and a mention of a recent crash in this county! Contacted him, and sure enough it was him. Nice bloke too, met him on a forum meet not long after.
In some weird way i find that well cool!

theres always a time and a place, im "lucky" in that sense that im always on the roads in the early hours after work, sometimes i drive the whole way home passing maybe 2 taxis, so theres opportunity when i feel like it, to strech the cars legs a bit ,never over do it but just every now n then

also go out of my house and theres some nice country nat speed limit roads....seems like every time i think lets have a little drive, theres some old f**ker going 30 mph along them with a 5 car tail back, danerous drivers i find old people, slow reactions, slow driving,20mph in 30 zones, 30 in 60 zones, and 40mph on motorways ,people like this should be taken off the road, especialy those that go 35-40 past the end of a slip road right as your trying to enter the motorway, with no sense ot move over a lane as its dangerous to do that right there :evil:
