Yes they can be made to work very well.
Expensive though for moderate power when compared to a turbo.
For cheap N/A power, an XE vauxhall lump is hard to beat and fits a type 9 with an adaptor thats readily availble

Its over to you

TB's make more sense, carbs are antiques.
You need different pistons, lots of headwork, different cams, different exhaust manifold, its LOAD of work.
On the other hand you could buy an XE vauxhall engine, bolt it in on a set of TB's and see 200bhp or so standard!
If its cheap power you are after, an N/A YB isnt a good choice really.

if y ou have half a brain and are resonably mechanically minded then a nasp cosiie doesnt cost much money really, buying the bits in the first place though will cost you a couple of grand. head, block , crank, pistons, management etc, there are many ways to do it, and results are quite rewarding 200hp comes along pretty easily.
and are somewhat heavier than its crocksall rival tho

but you can buy a over skimmed head for not much, find a old 205 block, crank and rods, only thing i see as a expense would be the cams and pistons itll be run on carbs or nothing so there about a grand

cylinder head Ł300
use a 205 pinto bottom end and crank Ł150
you will need to buy the cossie pulleys and bolts to fit it to the crank Ł50
cams reprofile a set Ł150
exh manifold/syste, Ł500
inlets- pref injection Ł1500
plus machining of the head/block and pistons to get the comp ratio right
Ł100
the rest is labour to port the head/manifolds and build the thing, then map it
that would get you 200hp at no more than 7600rpm on std inj rods/bolts

Why not put a brand new 2.3 Duratec in? I've seen these make 200+ bhp and 190 lb/ft on just throttle bodies and 2.0L cams....
Fair enough is new skool for an old skool car, but the duratec is a very good engine, 250 bhp is not that hard to get
Think you can pick up crate engines for Ł2K ?? (may be a bit less, can't remember exactly lol)

Yes the rally ones Mountune were about 280 but had to get rebuild very often.
The std i4 with some jenveys fitted n remapped should give you over 190bhp

You don't have to massive ammounts of headwork to a nat asp cossie, the heads have pretty good flow as standard so unless you want 250-300bhp its not too expensive. But, after you've put new pistons, cams etc and bought the engine etc you could have had an XE or zetec to 200bhp and saved a lot of cash.
I reckon for nat asp
upto 200bhp XE or zetec
200-240 - XE
240+ duratec or cossie
is the cheapest option.

Check out the latest edition of Classic Ford magazine and you will see Dave Colledge from Retro Ford's MkII Escort on the front cover.
Thats running a 2.3 Duratec that Mountune built and Dave developed all the bits to get it in, water rail, mounts, alternator coversion etc etc
Thats running on a pair of 45mm Jenveys and its 256bhp on the rollers.
There is work to be done on the exhaust manifolding as Dave built that himself too and he needs to increase the primary lengths to help up the power.
But as he built it in 6 weeks and developed all the bits to get it in,in that time too it wasnt bad going.
On its first outing, when the car had barely been run in on the rollers it ran a 13.01 on road tyres at the Classic Ford Show at Santa Pod.
There is nothing to stop you running Carbs or the Titan Motorsport Roller Barrells to sort out the induction side of things.
You dont have to go 2.3, a 2.0 from a Mondeo will see up near 190 bhp with decent management and proper throttle bodies etc
Retire that Pintosaurus to Jurassic Car Park !!
If you cant afford the Duratec, Retro Ford also do all the bits to get a Zetec in a MkI or II Escort and the ST170 motor is a Zetec..... nice cheap power.
Forget XE's.... they are for Homosexuals and Corsa drivers which amount to the same.... hence Chips interest
Ford engines should be in Ford cars... end of.

Why on earth would you want to put a big old heavy YB in
zetec is always going to be 30bhp down on an XE if you spend the same on both, however you can get a low millage zetec where the newest XE is 13 years old.....

I agree the XE is the daddy for cheap NA power, but i have seen quite a few n/a zetecs making 250 bhp recently.
2.3 duratec has the best potential but the engines are still a bit pricey compared to an old XE.
