I still on my 1st kit car which is a BEC.
Second type on engine (ZX12r)
Thing is though, if I was to build a second kit car I would want to have a new expirence.
So the choices would not be BEC or CEC rather than, Cobra / Ultima etc 
Still. Long way off that choice yet.
May be the next choice will be Turbo/Supercharger

Build two, one CEC & the other BEC have them the same colour, duplicate the chassis & number plates & then go out in whichever suits the
needs & best bit only one IVA.

These posts can go on for ever with people saying what they have got is better be it BEC or CEC all you can do is listen to the pro's and
con's of each.
There is one simple solution. Decide what YOU want from the car and this will determine the engine/car that you need.
If you want a civilised car that you can poodle round town in on a friday night posing to the girlies with hardly any clothes on on their way to the
night club and one that you can sit at 2000rpm at 70mph on a boring motorway journey touring for thousands of miles then a CEC is for you. On the
other hand if you want a car which will be more demanding to drive, harder to get used to a clutch which is like a switch and a throttle which when
you touch it the rev counter needle goes round like a catherine wheel but equally enjoyable to drive when you get to the open lanes and you open the
throttle, clutchless gear changes up the sequential gearbox, cornering like you're on rails and leaving everything in your dust then a BEC is
for you.
I personally chose a BEC because I really would like another motorbike. I have had big CC very fast Superbike replica's in the past but gave
them up because I have Kiddies to think of and there are so many day dreamers driving their tin boxes about with no regard for anyone else, plus I
could only go out on my own as the wife would have to look after kiddies and I wouldn't dream of taking one of them on a bike. The BEC gives me
the best of both worlds. I have the bike engine for the performance and sound but I can also take one of the family out with me if they want to. I
also wanted something different to drive as I do a lot of miles for my job and a CEC for me would be just like getting into my company car and going
off to work. There, they are my resons for MY choice, wether someone agree's or disagree's I don't give a sh1t as it is MY car not
their's. This is what you have to do to decide.

There are pros and cons of each. I'll try to be unbiased.
I know of both people who wish they had built a BEC and those who wish they built a CEC having built the other.
Both are fun to drive (I have driven both) within reason.
The biggest single downside as far as I am concerned with BEC's is the revs at a normal cruising speed are incredibly tiring. Hence why I built
a CEC. If I had a wanted a weekend toy for the track then I would have built a BEC, but I built mine knowing that I will be doing a lot of miles to
shows, meets and events. The other less 'important' downsides are the clutches dont last long and tend to overheat if you get stuck in
traffic and you have no reverse built in (ever tried reversing with a starter motor based reverse?! Its silly!) and the lack of torque means you are
up and down the box like a yo-yo.
There is only one downside to CEC over BEC and that is purely weight - which leads on to a lot of the other arguments. However a modern, all aluminium
car engine is also very light so that gap is closing up.
You can have just as much fun on the back roads in a CEC as in a BEC. Even with the lump of a pinto in the front I am never far behind anyone else if
out in a group. It will be interesting to see the difference with the duratec too!
Trouble is having a quick blast in one of each isn't enough to base a decision on. You need to weigh up what you want the car for and then make
the decision based on that. Don't be forced one way or the other by peoples opinions. Try to dig out the facts from this lot if you can!

Hmm sounds like that could make the question more interesting, BEC or race tuned CEC?
I'm going CEC for two reasons:
1. Don't want to be messing with anything more complicated than I need to for the first build.
2. I can get an engine free if the previous owner helps me build it

Having owned and driven BEC's and covered tens of thousands of miles on road, done numerous trackdays and spent probably three full days on drag
strips, I can honestly say that we have never once had to replace the clutch that came with the engine. As for them overheating in traffic..........
This also applies to the majority of other BEC's that we know of.
Best way to decide is to get a ride in each and see which you'd prefer.

Don't forget there are many different BEC engines as well as CEC engines.
I have just upgraded from a 1996 Suzuki RF900RS (5speed) engiine to a 2005 ZX12R engine.
Yes way more power, but so far not as good in traffic as the RF900.
I guess mainly because the ZX12R is not setup yet. But my old RF900 was just easy to drive, even in commuter traffic.
But I would have to agree on the cruising point.
I there there is a compromise.
Get a Suzuki GSXR1100 WN/WP and fit a 3.14 diff.
My RF900 (same gear box) only did 6500rpm at 70mph with a 3.92 diff.
A 3.14 i think should give a 5200rpm at 70mph, just crusing for a bike engine.
Still when I can get a 5l V8 cobra that does 50mpg I ready to change.

It probably will do if you push it!

I'd PERSONALLY go car engine, based on my experience of both (I also have a twin bike engined car! )
BUT, you need to try them both, and there are plenty on here who will gladly scare you witless with their car!
Try a good 200hp zetec or vauxhall XE engine one then try a ZX12 or R1 BEC and see how they compare, completely different, but not that different
against a watch, is the answer I got when we tried!
Even the zetec and XE cars will be totally different though, so who knows!
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning
