which is faster
Bike engined car or 2.0L zetec or are they close

0 - 30, the zetec is faster than a carbed R1 in an otherwise identical car, then you have to change gear with the zetec. By the the time you've
engaged 2nd, the R1 has matched your speed and by the time you reach 40, they're neck and neck. The r1 is accelerating faster and will reach 60
a second or more before the zetec. As both cars get faster the R1 will leave the zetec behind by an increasing margin as it has more power to
overcome drag.
Tune your zetec up by a reasonable ammount and you'll pull a bigger lead in 1st gear. It will take the R1 more time to catch up. You need more
power in your zetec than the equivelent bike to match it in acceleration, but then you'll have a slightly higher top speed.
A stock 2.0 Zetec has 135 BHP IIRC. 1.0 Bike engines have 140-150 BHP if they're old or 170-180 if they're new. All will have a few BHP
more if fitted with a straight through silencer, foam filter and suitable remap / rejet.
The cost of your zetec + carbs or EFI plus tuning upto enough power to match an R1 would cost quite a bit more than an R1 installation. You then get
quieter cruising and a free reverse gear. You pay's you money...

Faster how?
Top speed or acceleration?
Or to put it another way- CEC or BEC

I don't agree that a zetec installation costs more than an R1.
You can't get an R1 motor for much less than a grand yet you can pick a whole Mondeo up for £50, add on bike carbs and megajolt and your nowhere

Interestingly the argument takes on another dimension with current R1 engine prices...
Engines are fetching about £500 at the moment which puts zetec and pinto tuning into perspective.
Puts tuning up old CBR engines into perspective aswell!

It's got to be the BEC 
Well, providing that you can a) get the power down and b) get off the line without stalling

BEC vs CEC
You can almost put money on, that some of the old guard will be along promptly telling you which is best.......
I may be old but I'm biased too!
0-60 3.48 secs...That would be a "Busa" BEC

I think if I could get a sequential gearbox affordably for a CEC I would go Nissan or Volvo Turbo.
In South Africa used Busa motors are around 3000 Pounds if you can get them so are not a possibility unless your budget counts for nothing 
For that you can get a fully modified (and reasonably reliable - about 20 000K between rebuilds if you don't over rev it) Mazda turbo rotary
putting out anything between 350 - 450 hp depending on boost button chosen. Lets see a BEC keep up with that!

Someone mention carbed R1. What about injection?
I thought 0-60 times on an R1 Bec were around 3.5-4 seconds. Can the Zetec really be faster?
My next project is an R1 injection. I bought a 700 mile engine for £1800.
These £500 engines must be pretty high mileage and possibly need replacing often?

I said that a zetec TUNED to match the acceleration of an R1 would cost more. A basic zetec installation would cost less but be slower. My R1
engine, ancillaries, clocks, dynojet kit, the lot cost less than £1k

Anyone who's thinks of asking the age old question should first get a ride in someones car.
I had a drive in a zetec car first, while good fun, not my cup of after being a biker.
But then came the BEC, although not as fast as my bike, I'd never accellerated in a car that fast. I had to have one. But as Chris says,
it's a f*cking nuisance in traffic.

hmmmm, far too vague a question to answer, which I think is how the answers have gone.
If you are specifically saying zetec, not "car engine" then performance per pound a bike engine is a better bet.
Yes a zetec can be made quicker than most bike engine cars including busas, but you will have to spend more than busa money on it to do it.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

I don't understand why some people try to imply everything is an argument, this is a light hearted discussion about BEC v CEC, that's it,
end of story.
Some prefer BEC and some prefer CEC but nothing wrong with a bit of friendly banter.

Here is a graph I made a few weeks ago comparing a standard 2.0 zetec against a standard 1998 R1 in otherwise identical cars. It assumes 3.62 diffs,
195/50/15 tyres, the same aerodynamics, the same weight other than engine/gearbox and takes true account of drag, rolling resistance and tranmission
losses. Given that, I don't claim 100% accuracy.

You haven't taken into account engine and gearbox weight?
Surely, this will make a big difference?
(I am not calling you Surely ! )
Perhaps 50kg difference?

My model doesn't take account of wheel spin or clutch slip. It assumes that you have perfect grip and that a slipping clutch transmitts all the
torque of the engine, which I know is incorrect. on double checking the figures, I realised that the powertrain losses were a bit too low as well.
It affects the zetec more than the R1.

The zetec is 70kg heavier in my calculations.
Here is a graph of a tuned zetec giving 190 BHP. This was simulated by adding 32% to all the torque calculations. The R1 makes 148 BHP. I've
corrected a few things in the calulations like wheel diameter, tyre stickiness and transmission loss in an attempt to improve the accuracy of the
model.

in answer to the question an r1 bec would destroy a zetec car even with a few mods..
