Hi all,

Just looking for a little bit of info really, In the process of buying another Escort RS Turbo 6 years on after my last.

The last one I bought was 180bhp running the standard mfi, a cam, chip actuator etc...

Back then I was 18 and I didn't really know much mechanically about cars, as time went on I ended up going on to build Renault 5 GT Turbo engines for a living before joining the Railway.

RS Turbo's are a different ball game to me having the injection etc...

Looking to build an engine around 250 bhp, what parts will be involved to do this? Will I be better to go for EFi out of a fiesta? When people say running cosworth management in adverts what do they mean by this?

Would I be better getting rid of the 1.6 bottom end and getting a 2L etc? 8v or 16v? And what is ZVH? Also looking for a good reliability too.

Luckily I can keep the cost's down by doing it myself, wheres the best place to get parts from aswell?

Thank you
Billy

PS sorry for all the questions

 

For a good 250 engine you want idealy forged piston and rods, running it on EFI as your can tune it alot better. You will also need headwork and a cam, and as for the turbo you will need a decent stage T3 or a cossie one (im sure a few of the other lads can spec a better turbo).

Cossie managment basicly is your EFI engine running Cosworth Managment...ECU, loom, sensors, Throttle boddy etc...

As to what bottom end you want depends on what power you want...
You can get 250 out of a 1600 but that would be pushing it. After that you could go ZVH which basicly mean you run the standard CVH 8v head with a 2.0 zetec bottom end. If you wanted 300+ then you would need to build a zetec turbo.

 

buy an mfi rs turbo ....

buy efi inlet and adaptor plate
ported and polished head and inlet
and uprated cam will be able to get there but newman are the best
gotech/omex/ cossy management
stage3 t3 £500 brand new
rods and pistons with bearings bolts and gaskets (use genuine ford gaskets )
decent clutch
hoses
intercooler and rad

and your half way there mate
but will need alot of this to run 250bhp safely.....

its cost me around £4k to source all of the parts to do (including a grand for my wheels and brakes) and ive got a little more to get but hopefully will be worth it.

 

good advice from both the lads above,

but id stay with the 1.6 rather than the zetec turbo, its much stronger

and as for safe power, you need to use good quality parts, you could even get 240bhp by sticking with mfi if you wish

just depends on what you'd prefer to do m8y there are alot of options

 

and what makes you think a cvh is stronger than a zetec?

 

why because the cvh is made for a turbo engine, the zetec is nt you have to make it to take the turbo head

 

what was the focus rs a toaster

 

lol, thats already made from factory, thats a different engine

 

My best advice? Buy one that has already had the work done by a reputable tuner, much cheaper in the long run

 

Rubbish the zetec is a far stronger engine, and the cvh if i remember rightly started off in escorts 1.3, 1.4, 1.6 etc without turbo so it wasnt built for a turbo at all, and the xr2 mk2, xr3, xr3i etc

 

is mulla off here not sellin his 2.1 zvh, brand new engine never been run, think he wants 3k for it, well worth the money imo.

 

Hi all,

Alot of good advice there, so would I be right in saying you can just get any Zetec bottom end i.e. st170 for example and mate it up to the CVH head?

If so how do they go about lowing the compression? Low comp pistons or spacer plate between the head and block?

I thought with the Zetec bottom end you'd have to fit stronger internals?

Looking to do more engine work rather than doing a few simple mods then cranking up the boost to compensate for the power I want.

I am thinking of getting a bottom end with a larger cc for the simple reason a 1.6 may struggle for reliability putting out 250bhp especially for every day use. Could be wrong though, please don't quote me.

I get my experience from Renault 5 Turbo's mind you , to be honest not a bad car if built correctly but the 1400 stuggles on reliability with power over 180bhp. Also they get a bad name due to silly people running with the actuator pipe off and they wonder why they go pop pumping 34psi through a standard engine?

Thanks for all the replies

 

Some of the biggest BHP RST escorts have been CVH engines. Must be a reason for that?

 

the focus rs engine is a zetec turbo! blacktop zetec turbo

 

you have not seen alot of rs turbos then

 

Christians, tony turbos. Two of the biggest power ones ive seen.

 

for big power figures cvh is not the way to go.

http://devil-developments.co.uk/Mattsfiesta.aspx

this one 320bhp @0.6bar!!

http://devil-developments.co.uk/leecab.aspx

this one near 400bhp

http://devil-developments.co.uk/Zete...FiestaRST.aspx

 

show me a 600hp cvh. Or one that has done sub 4sec to 60 sub 6sec to 100 and 10 sec's to 150!

 

mate dont get a zetec bottom end and mate to a cvh head if you are gunna do it just go full zetec it will cost less in the long run ..... and the scope for tuning is endless or you can stick with the 1600 for a bit of old skool cool....

but it depends on your preference as this is a sticky subject and we will end up with another 60page thread lol

 

Great advice Mark!

 

someone has got to say it before the d4rst's of pf come out with their handbags

 

zvh

 

Thank's again for all the replies

Just looking at engines on the net at the moment, can I please get some opinion's on a Focus ST170 engine turbocharged?

Has anyone on the forum done it? I seems not a bad Idea, starting off with 170bhp then add a set of cams, head work and a turbo. What management would I require? Or can you just chip/re-map the ST170 ECU?

What would be a rough expected power output?

Thank's

 

Put a post in GD about the ST170 engine, will get a wider audience and more responses as might not have been done in a RST but certainly will have in a Focus i'm sure!!

 

i would just speak to s1 john he has the following forsale cheap
woszner forged pistons £100
pec steel rods with pins bearings bolts ect £200
mint block machinced for pistons ect mint £80
mint condition fully balanced crank thats fully polished ect £80

so thats a top spec bottom end for like £450 then spend 200ish gaskets and bolts and 350 porting your head and £300 on a cam kit and you have a top spec engine.

then £500 stage3 t3
max £1500 management fully fitted and mapped

this will be a very strong 250bhp all day long

for £3300 all in

 

i did it about 3 years ago running high comp t34 management kept the vvt ect, imo just built a zetec far better.

 

hi mate check out sitech racing ,his web sites helpful and his done zvh and st170 head mated to rs focus bottom end http://sitechracing.co.uk/products-ford.asp also check out stu collins 1.6 rs turbo https://passionford.com/forum/restor...73-122mph.html . only other thing to sugest is using r5 gt turbo carb or 2 mated to cvh there is a few fiesta done like this could be a cheap starting point . ive had 11 renault 5 gt turbos there great

 

Is there anything you havent tried Gary??!! lol

My Ka box didnt turn up Friday so havent had a play with fitting that yet, hopefully will be here tomorrow and I can get stuck in!

 

Cheers for that i'll have a look

 

That's not a bad price, still haven't saved enough for a good RS yet. Got works bonus etc... coming next month to add to what I already have so hopefully it will work out to get a decent build.

 

Cheers for that, that seems like a common mod putting a 5 turbo carb on other engines, it's the same with citroens/pugs!

Worked on a good few 11's I have a 1986 Ren 9 turbo tucked away waiting for a build too it's been sitting like a burst ball for ages!!

 

thats it it aint bad for the spec and it will keep the car a bit sort of original keeping the 1600 ect

not really, thats how we gained our knowledge that we try to pass on if we comment on it means one of us has tried it at some time next thing on list to master is nos
