91' 318is vs 85' 325e

M42 cars really aren't as bad as people make them seem.
Just imagine owning an eta....

I've had both, M42 all the way.

I liked the low end torque of the eta motor.

Thats it tho. WTF. 4.5k redline?

[stamar]

Not necessarily. Torque, gearing and aerodynamics play a role in top speed as well.

ok for the same vehicle and one being lighter, the lighter vehicle with more horsepower will win a top speed race.

but you can make a race that an eta will win where the top speed doesnt matter.

anyhow they keep statistics on these two cars and the 1/4 mile time is the same. And the eta is winning one lap and the 318 catches up and its an exciting exact same tie.

I swear I wouldnt make it up.

as far as take off ability.

There is no reason a 318 should have a better 0-30 time.

It is actually like 60 lb ft tq less, with a higher ration gear and 100 lbs on its side but it wont be close. It is close to gutless from the line losing out to most economy cars.


the only eta I drove though was an automatic, it was some kind of like semi diesel vehicle sort of ride. Good off the line though but sad at about 35 mph.

You guys can talk trash, come race my all stock-parts 327i. Pulled a m30b35 swap with a 2.93 rear...

Yes there is. Its called gearing and much wider power band.

Keep telling yourself that.

it shows.

Also to consider, my 318 is at 220k, the eta was at 114k and well maintained just for the record.

still doesn't mean the compression on the motor was good. My iS seems really buzzy and nimble, where a 325 is much quieter/smoother which can make a car seem slower- boring also. it is also 2 different styles of driving needed for those 2 motors. high RPMs aren't going to do anything for an ETA, where an M42 does NOTHING at 2000RPMs.

I would probably rather have a good M42 than a stock ETA though.

That's irrelevant to this thread. But that M30 car must have had some serious problems.

[ForcedFirebird]

Eta 1/4 mile = 16.8, top speed 120 (mine confirmed this)
318is 1/4 = 17.2, top speed 106

They are practically equal.

It's far from stock lol.

^^ Although I cannot confirm I have to disagree, 5th gear, at 4k rpms I'm just over 90mph, I doubt 106 is really top speed?

According to the car's specs top speed should be 127mph in a 91 318is. I'm not sure where you got your statistics?

And you have confirmed that your Eta's top speed is 120.

I am going to do some 0-60 and quarter mile trial runs with my 318is

Thanks to everyone for the very interesting thread, this has sparked much more interest then I had before
