BEC or CEC
I have a Westfield chassis.I've been offered a ZX9R engine complete with loom etc for £300.I originally palnned to use a 1300cc Toyota Starlet
turbo engine with approx 180 bhp.Uprights,brakes etc will be MX5.I'm looking for the opinions of guys with experience of BEC and CEC to help
make my mind up.I've just had a run in a Hyabusa powered westfield and I was well impressed.The car will be mostly for road use with the
occasional track day.

As you've said 'mostly for road', then it has to be a car-engine for me!

Engine
I don't want this to turn into a BEC v CEC slanging match.I'd like your preference and the reasons why thats your preference.I can also
get a GSXR 750 injection set up for the same money as the ZX9R carb set up.

I think in all honesty a CEC would be a simpler build/conversion....what is the chassis that you have configured for?

My thoughts...
I've had both.
A BEC is great fun when you're in banzai-mode and want to attack every stretch of tarmac as if you're on an F1 qually lap! It's a
complete pain in the backside if you just fancy a leisurely drive, or have to nip into town as it's noisy and you're always busy on the
gears.
A CEC offers a little more choice. Just decide on the engine... rotary screamer, torquey V6, or somewhere in the middle like a Duratec. The world is
your lobster!
If you're concerned about weight, then a Duratec and Type-9 box combo need only weigh around 60kg more than a featherweight BEC. A locost set
of throttle bodies and a half-decent exhaust and you're looking at 200bhp and a shed-load more torque than even a forced-induction bike to move
that extra bulk around!
Sure, there's not the same drama in a CEC as in a BEC, but quite often that's not a bad thing!!!
It's Evolution Baby!

I have had both in my car and for road use I prefer the car engine.

Engine choice
Sounds like a CEC is the way for me i'm getting on a bit so maybe the BEC driving characteristics wouldn't suit me.I have an Omega 3.2 v6
but i'm thinking it's weight would spoil the handling on a lightweight sportscar.

A V6 need not be heavy - I use the Mazda KL in my Fury , and it's lighter than a lot of fours (110 kg's bare)
And with 200 bhp as well as plenty of revs it sure is a hoot , as well as very civilized round town
Its cuz I is blond , innit

It's quite amusing this BEC vs CEC.
Performance wise, BEC wins.
However, once you draw a line under that, it reall is personal preference.
The whole torque thing, apart from being wrong (Gearbox people), is interesting.
Having grown up with Hondas, they offer relatively small capacity engines with high power.
Current car that i'm dismantling is the S2000.
Torque wise, it has 155lbs/ft and weighs in at 1200kg
I never had an issue with pottering around town in it and it has a lower torque/weight ratio than most BECs.
Back to that engine, the F20C, I was going to put it into a CEC.
The F20C represents the pinnacle of car production fours with 250ps (JDM) as standard, roller valve train and forged internals.
It is simply too heavy compared to a BEC and the power wouldn't offset the weight.
Still, like I said, personal preference.

My BEC is mad and great fun, but if I was honest I would probally use the car more on social occassions if it was a CEC. BEC = Crazy track day/very
fast maniac road use CEC= Quick fun everyday civilised road use. Depends whether you are tourer or a aspiring racing driver.
Now where's the popcorn

simple answer to this..
Do you want a 4 wheeled sports bike (no screen, no heater, no roof, wear a helmet, other half might get in it once then not interested  ) ? - BEC
Do you want a car (with windscreen, doors, roof, heater, radio, other half will get in it & might even drive it  ) ? CEC 
My conscience is clear - I drive a GREEN car

A very eloquent response so a 'ditto' from me!

Just to add on the road a 200bhp cec would be quicker a to b. You can't use the few extra mph corner speed on most roads. 1/4 mile times show
that's the sort of poke you need. Add to that the lower cost too

BEC all the way..... Sequential, clutchless, paddleshift gears make it easy to use on a leisurely drive out and you can make a BEC scream (or not) by
adjusting the pressure you apply to the throttle with your right foot.
Get it on a track and you'll realise you've made the right decision. Trackdays are quite addictive though....
There are quite a lot of people who have converted from CEC to BEC and most would never go back. Conversely, there is also a few people who've
gone from BEC to CEC. I suspect some will be back when they've come to their senses..............
