Ive got problem with i cant decide what to build engine wise ive got a escort rs turbo that i have just bought with a knackered engine so have pulled it apart and found its totally goosed # 3 piston holed bore heavily scored ran to much boost i think and turbo shot so i have got a new turbo stg 3 hybrid for it now ive got a good cvh block
I also have a good 2.0 ltr silver top mondeo engine . So do i split that and build a zvh or just bulid the cvh back up or build a full blown zetec turbo

Any help from people that have done this would be appricated

realistically another cvh turbo would be the cheapest as all the fuelling and all that is there.
just replace engine and tune it.
next up would be zetec turbo, done one, loved it, but not cheap if you are chasing figures above 300bhp IMO

Cheeres for that i might build the cvh back up and collect the bits to bulid the zetec turbo later on when the urge for more power kicks in

Whats youre budget like?

Building upa cvh to take stg 3 power output may well be just as costly to build up zetec T to take smiliar levels. The zetec build could provide some form of futre proofing where as the cvh is relisticly going to need swapped out or extensivly modified if you feel you require more power down the line.

Yes i been looking into the cost of a zetec turbo build and your rite its going to cost a fair bit of wonga but i can save some money on the labour as i can do all the work myself on it but think it be more realiable than the cvh

v man

Build a zetec turbo

Do it once do it right

great idea buddy

whilst i love a zetec turbo, building up a cvh turbo engine is cheap and no hassle.
nothing needs modifying and can be up and running very quickly especially as all you need is an engine.
a zetec requires a lot more expense as IMO there is no point throwing a budget zetec together, unless you have a handy supply of standard engines and you're going for low power.
up until recently had a forged, cam'ed, gt30, frs box xr2, it went very well, but cost a lot as there were issues with lesser spec turbos, inferior clutches etc.
zetecs are brilliant, but the cost of doing it "right" isn't cheap, 3k on an engine to mid spec, £1500 on gearbox conversion and clutch (including electronic speedo), mounts and all that stuff, management, fuel setup sees another grand happily.

i think to get the car running whilst you build up a new power plant makes more sense, you've not had it driving, so need to enjoy it in good time.

Yes very true im looking to get 240 bhp which ive been told is achivable out a cvh turbo with very little cash is this the case and can i still use my stg 3 hybrid turbo with it ?

should be feasible, i have had cvh/zvh and the zt, nothing launches you like a zt, but i was chasing power in excess of 400bhp, i just never got it on the dyno sadly, but 2BAR of boost through one of those turbos is plenty quick.

i did have a cvh turbo and wasn't blown away, but with some work they can produce good power and some parts like IC (when upgraded) will be useable for more power in the future.

You are going to need a rod and piston package at that power on a cvh so you may aswell get a rod and piston package for that silver top 2.0ltr you have

The standard series 2 metering unit will struggle safely at 240 it can be done but you will be ringing its neck so you may aswell get a cheap cossie management set up

So again you could always run the zetec on cossie management

The standard zetec with steel rods and decent pistons will run 300 with ease
And depending on how you drive you could still use the series 2 box

only rods needed for 240bhp on a cvh turbo, pistons can more than handle 300bhp.
metering units are the weak link, but 220bhp is a safer target, no need for rods then and more than adequate power.

Yeah chasing the dream lol cheeres for the advice buddy im going to rebuild the cvh and get that running spot on and hopefully get the 240 im looking for and collect the parts i need to build the zt when i can afford them im a great belivere in building it rite first time

Awsome fiesta you got yourself

St170 block, blacktop head will take 300bhp and doesn't cost much

0150carmac

5th injector set up ?

0150carmac

Good point changing to cossie mamagement would solve a few problems

Im not to harsh on gearboxes

do not bother with cossie management, get omex, dta or anything that's 20 years of newer technology.
cossie management isn't even that cheap to bother anymore.

0150carmac

I was just looking at the omex management looks good for the money

It costs a fair bit when you add all the little bits up. I'm currently building mine up.

st170 engine was about £400
New zetec head and cams £300 (I chose new)
decent head gasket £100 (ford item has been on back order for ages\0
exh mani adapter £40
timing belt kit £40
sump gasket £40
arp rod bolts £60 iirc
sump mods cost me £70

then all the other little bits clutch, inlet, turbo upgrades, other gaskets and consumables, aux belt, modded engine mounts, mapping etc etc

Its gonna have cost me well over a grand and thats with already having megaquirt installed to run it.

i did sell the st170 head for £170 iirc
but it should sound a lot better than a cvh and less risk of it cracking its engine block.

0150carmac

Yes looks like the best route to go i terms of relaibility

luke19790_3

Guess I've been lucky with prices, I'm building 1 too,

luke19790_3

What sump mods did you have for £70??

studabear

Fittings were £5 each, plus the sump had to built up with weld on both sides, then drilled and tapped which was £60. Although this did also include a helicoil fitment into the frs top hat I'm using so I can use the cossie act sensor.
