they are the two worse bits of each engine

zetec head makes so much difference and its cheaper to build a full blown zetec

and theres so much off the shelf parts that its an easy conversion, rouse do water hose kits for the conversion off the shelf.

im using a cvh manifold and a blacktop/frs inlet, dont bother with adaptor plates as its a couple of hours work to drill and tap the head to fit the cvh exhaust manifold.

both of these will piss 300bhp and i got a complete blacktop inlet including throttle bodie and fuel rail for £35 and the fiesta rs turbo fuel pressure reg bolts straight too it, so the only custom bit needed to fit is a charge pipe, and the best bit of this inlet is you can close your bonnet without stupid spacers

use a 1.8 zetec sump and pickup and water pump and your downpipe will fit straight up as will the turbo you have sat there.

for the thermostat housing there is a kit on ebay that makes the cvh thermostat bolt to the zetec head for £25 so you can have the fans running off you exsisting car loom and not on a switch

get a zetec alternator pulley and that bolts to your alternator too


the best bit is theres so many bits you can re-use

apart from the engine the main bits you will need to change are

drill your flywheel to bolt to the zetec crank
drill and tap the head
breather and oil return ect
bottom water hose as the zetec water pump has a different outlet size
need pulley for alternator and belt
make a charge pipe
thermostat housing conversion plate
fuel pipes in engine bay

and pretty much everything else will fit upto this with what you have.

and if you are efi or cossie management then use what you already have and it will work unless you are on cossie management then you need a new cam sensor bracket

and with aftermarket management theres endless choices, use a efi loom and sensors and fit a boost monkeys ofam ecu with the upgrades?

it wont stop it lifting but will stop it blowing if it does as the rings a machined in to the top of the block all the gasket does is stop oil and water mix now , rated to 3bar

rsmark86

iTrader: (3)

so its like the old cossie route of wire ringing the block and useing a group a gasket?

this route worked fine on one of my old cossies at 30psi boost

rsmark86

iTrader: (3)

6k ? i would rather use a focus rs tall block and spend the money else where and getting the most drivability possible and having a bullet proof trainsmission and a solid 350bhp

stuart collins

iTrader: (7)

no , if is was wire ringing the block i would have said that

Blocks machined?

I love a good cvh turbo but if your chasing numbers and power why bother with a cvh when a zetec turbo will do a reliable 400hp for half the price

Not saying that cvh,s are shit look at stu's it's a full on monster and puts the times in down the drag strip

StephenC

Don't know what to do now! As said earlier, whatever I do it'll need new fuel system and wiring/management so really any engine is an option as long as it fits. Truth be told I fancied and evo engine with evo box converted to FWD, circa 400-450bhp and would take abuse all day long. Then I thought, well, I've got this old nms engine doing nothing, let's salvage some of that. The smart money looks like a zetec turbo, and my only reason not to as sad as it sounds, is I don't like the look of them!!!!!

StephenC

So which zetec turbos are we looking at for inspiration, off the top of my head there's Luca fiesta?

QplateRST!

Depends what you want to use it for ie drag, track or road
what you budget is and how reliable you want it

That fat little bold scouse bloke who has the Mk1 focus RS' 500+ bhp

HAS to be a Zetec turbo these days, have a chat with Devil Developments top bunch and will get you the power you're after no worries!!

For me, only people who are racing to regulations have a reason to stick with a CVH turbo... and only retards would want one for big power on the road*

*Stu nothwithstanding! He's not a retard he's a top bloke met him whilst featuring his car many many years ago!

StephenC

Want it for drag, track and road really. Budget I'd say 6-10k and want it very reliable. Really don't want it breaking every time I take it out.

QplateRST!

Buy a mk1 focus rs tune it job done

There's people fitting Honda k20 vtecs, fully forged with vipec v88 and efr turbos in fords these days

And they fit, 9500/10000 revs, 500bhp on a lowish boost engine, the head on a k20 will flow good for 700bhp with just some up rated cams, so if I had the money I would look at a different tyre of engine other than a ford

Street racers fitted a Evo engine running a mk2 frs gearbox (fwd) and it makes 609bhp in a pug 205

6k for a cvh, I would rather look else where

rsmark86

iTrader: (3)

There's a guy running in time attack with a black s1 running a full focus rs mk1 running gear on aftermarket ecu and around 300bhp and wins everything in his class racing things like a 550bhp astra vxr?

To get 300bhp out of a focus rs engine all that's needed it
Forge actuator
Up rated exhaust manifold
Decent intercooler
Free flowing exhaust system turbo back
Induction kit
Remapp, in your case management

Standard box, clutch, ancillarys are all at there best still at this "mild" state of tune

And to fit the engine it's the same as a zetec turbo, but fit the frs box and you will need shafts and mount kit of crazycage on here

If you have oil problems have a look at an Accu sump!

Collins uses one in there focus! They very effectivly stop oil starvation on a standard sump!

I use one in my CVH happy to provide pics if needed!

I was under the impression that for high power builds the CGI Zetec block was used. These are no longer being manufactured, and are expensive if you can find one.
Easy power increase is extra displacement 2.0 instead of 1.6.
But you need a well prepared cylinder head, inlet, and exhaust working together to supply enough air/fuel for a 2.0.
It is not the most cost effective to build a big power CVH - but I love them!

The tall 1.9 block is certainly not stronger than the standard 1.6. It just provides larger displacement and is better than an overbored 1.6.

rsmark86

Tall blocks are no better than a cvh, the zetec bottom end is not the best

It's the zetec head that makes all the difference

And I've not heard of one frs having oil pump problems, especially at 300bhp so if I was building one I would save myself hassle and cash and buy a frs tall block, then fit a tubular manifold and a johnfrs hybrid and new injectors and have a punchy 330bhp

I know what you mean there

For some reason I'm stuck on my cvh
I love it

Duratec turbo?

Could run a nice cosworth or mountune inlet and a custom manifold and they make serious hp

Mondeo mtx bolts up, and I have heard that a mk2 frs 6speed does ( but will need to check) and the frs mk2 box has been in 600bhp cars without issues so far

Or be different and fit a mk2 frs engine and box, that would be awesome

StephenC

Too many options. I think turbod Valencia and call it a day

crazycage

i'd go for a evo engine . if I could turn the clock back that's what I would of done to mine . got to much money tied up in my zetec to change now

StephenC

I was set on the evo, guy up our way does the gearbox conversion and runs it in that drag FTO at silly power. Would be reliable as fuck too at the power I want.

gus

iTrader: (1)

o thats what i was trying to say

hows the candle sticks coming on???

crazycage

there getting there lol im sure im burning the candle at both ends tho.

I have thought about selling off the zetec parts but I don't like the idea of giving in ,might build a evo powered escort later in the year

rsmark86

iTrader: (3)

Remember to make templates as a few of us may follow lol

crazycage

the only problem I can see with it is fitting it to a gearbox the rest isn't any different to fitting a zetec

Joe91

It's not a bad thing? I have plenty on people ask what 'power' I'm running and I tell them and they say 'is that a Zetec turbo?' No it's not actually its 1.6cvh, zetecs and zvh's are very common these days for the reasons discussed above but some of us have alot of money in our cvh's and can't let them go! I just prefer to say I have a powerful cvh instead of Zetec or zvh..

As for the O.P. it depends what you want and how much your willing to pay, I'm about to go back up to NMS for mapping my new T34 to 28psi, it will be near the 300bhp mark, any more and it will be unreliable and won't last to long..Karl said he has stopped making big power cvh's now which is fair enough, I'm sure they would still make you one if you wanted it?

Had anyone used liners in the cvh block?? As
I have been looking at my options before car is
Ready for engine to go in

i spoke about

i want to build another engine but do something different to the norm
so was chatting about it and sorting a plan

then my work went belly up

so thats as far as it got

creator

gary,rob @ constella has an evo engine in his 205 bolted to a mk1 focus rs box maybe worth having a word if intrested mate.

russ rs

I know feeling about work etc car comes last lol.
I got access to liners and measured up its if cam justify
As stu said mite aswell steel crank then

gus

iTrader: (1)

i was thinking big bore short stroke so would of been a custom crank

or maybe the complete oposite

lol

StephenC

I spoke to Rob about it last year and he said it was a nightmare to do and they wouldnt really be happy doing another as it wouldnt be worth it to them, as in, once theyve sold one it will get copied and sold cheaper. Think he had a lot of welding and machining to the bell housing. My plan was to keep the evo box, convert it to fwd (think its new diff, blanking plate and a few other bits) then use V6 FTO driveshaft inners mated to ford outers (dave mac shafts). BUT, the kit alone to go fwd is 3k which is a bit steep really, im sure you could get a mk1 or mk2 FRS box and get the machining done to that for less.
An EVO engine would also look pretty nice in the series 2 engine bay. Think the first thing to do is measure up to make sure it would fit. Dont suppose anyone has any access or knows of any measurements of a) an EVO block and any ancilliaries on the crank end and b) the various gearbox options and finally c) the space in the mk4 bay before modifying.?
