Interesting dilemma. I kind of like your present setup, but then, I've never had an English engine for long enough to know how much it leaks and
needs fiddling. I also understand your desire to twiddle with your car during winter. I don't have an answer, but I think your course of action
will be dictated by how much money you really want to spend, one ten pound note at a time, of course, just like everyone on here.

I am running a zetec and am in agreement about the X-flow, I only ran a GT spec X- flow with EFI for a while and changed to a Zetec when it needed a
rebuild as I could not justify the cost of rebuilding a X-flow when Zetecs are so cheap and give good power.

kind of power.
Take a bog standard Zetec, put on a good inlet and exhaust manifold, bike carbs and MJ and you have an engine that it would be very expensive for a
X-Flow to match.

Of course you can get good power out of a X-Flow, but not cheaply.
The crossflow has it's fans and good luck to them (I enjoyed mine), each to his own, that's the joy of kits, there is no right way to do
it, but the Zetec is the better engine (and cheaper).

Could the same be said for a bike engine compared to a Zetec though? And much lighter.
I loved my Crossflowed MK1 Escort though, 1300 dry sump, full steel engine on 45s and a Holbay K3A cam, fun to 8,500rpm. It had a seat in it and that
was about it. (Getting misty eyed now, best have a look on eBay for a reality check).
DO NOT PUT ON KNOB OR BOLLOCKS!

Another way of looking at it is does the crossflow need replacing ? If it doesn't at the moment then start sourcing the parts for the conversion
to Zetec for when it does or at least price up for doing either. Unless of course you want to change it and just need an excuse? One day I will
probably change from crossflow ??

Not quite, a good Zetec can be picked up for as little as £50 (that's what mine cost). Could a decent bike engine be bought for that little.

Thanks for your inputs but really think this is the one for me, keep the xflow and enjoy the summer and think about slowly collecting bit (apart from
megajolt parts)
Already got the megajolt, edis, coils pack + leads and the trigger wheel is in the post  just a tps and crank sensor to go !!
having fun on a budget

The crossflow is pretty light, certainly no heavier than the Zetec. It's also a nice compact, short engine and retrofitting a modern(ish) DOHC
in it's place can give a load of grief trying to get clearance.
If you are going to go to all the trouble of fitting a new engine, I'd definitely want a bigger improvement in performance than you'd get
going from a tuned crossflow to a standard Zetec.

It certainly is not. Engines produce torque which a dynamometer meaures. Then by some cunning mathematics this is converted to horespower (BHP as we
know it) for 2 simple reasons, no one understands torque and everbody understands horsepower.
I was a x-flow die hard for many years, 1988 to 2002 to be precise. My best motor was an 1860 long stroke version that I built using parts and favours
over a couple of years. At the time people were paying £6000 plus for similar motors, mine cost about £2,000. It peaked at an approx corrected 175 bhp
at 7400 rpm, the torque was 130 lbs/ft at 6000 rpm. The engine embarassed many more powerful BDA's, BDG's and later 16 valve Vauxhalls on
the hills simply because of the way it delivered its power smoothly over a wide rev band. The oposition may have had more power, up to 260 bhp in some
cases but they did not have the torque to pull them out of the corners that I did.
In 2002 I decided to move on and fitted a Zetec. Standard 2 litre from a burn out, fitted a set of ARP bolts and a pair of Kent FZ2002 cams and new
followers. On the same rollers it peaked at 178 bhp at 7200 rpm with 150 lbs/ft of torque at 5300 rpm. With little more power and a bit of extra
weight I was able to beat my best cross flow times but not by much, again it was down to the torque available out of the corners. People who had spent
£1000s must have been sick to see a £150 motor plus a few bolt on bits beating their mega expensive engines.
Those peple had bought their engines purely because of the high power figures quoted, I was able to beat them with 80 bhp less and a good spread of
torque.
I still love the old x-flow but times have moved on and I think the Zetec is an absolute cracker but don't expect a swap to be cheap.

similar dilemma here but for next winter, at the moment just gearing up for it. decision is kind already made for me as i'm going to get a
zetec. would be interesting if somebody can write a guid with all whats needed for the conversion...
