Alright guys im looking at buying an s2 rst in about three months ish, and basically i want to have somthing to do now. So how complicated is it to build a zvh? I know a 2.0 is a bit more complicated than a 1.8 but which would i be better at having a bash at? also please could someone list every part i would need? i am greatfull of any help, cheers

 

why not just buy one with the coversion done

saves the hassle and hard work

 

Without sounding ignorant if i built my own i would know it alot better than an engine anyone else had built. Plus i just fancied having a crack at one myself, to be honest i arent that sure wether i would be better sticking with cvh

 

id have a go urself mate.. if uve got some common sense its a easier job than ud think.. the previous zvh's ive rebuilt/built have worked out just as cheap if not cheaper than rebuilding a cvh bttm end...plus improving the torque no end... get all the basic rebuild parts, sort the oil ways in the zetec block (any local engineering company) water pump adaptor plate, Ł20, 1.3 cvh tensioner, use ur cvh bttom pulley etc etc n ul b away.....

 

I have had the pleasure of owning a 2.1 zvh and cvh rs turbo mate and to be honest the cvh is a much better car imo

 

Im no machanic but i am a door engineer (fitter) so im ok with a set of tools i just thought a decent guide would help

 

Take a look at this sit Mate most of it is very comprehesivly explained www.quantums.info/zvh.htm . 2 other good sorces of bits and info are
1,Mad for it in Cornwall/Cheap n cherful
or
2 Ian Howells are Area 6/not so cheap but VERY SOUND ENGINEERING

Good luck

 

This is where you wanna go bud www.quantums.info/zvh.htm this is how i did mine. defo do it yerself good fun lol "if you have good mates"

 

i have a zvh and i did all the work for mine loads off fun

 

im in the middle of building my 1.8 zvh, and its not rocket sience mate, if your goodwith tools its quite easy.
i made all the conversion parts myself which has cost me a total of Ł1.45.

the most ex[ensive parts are the re-build parts, like rings, bearings, oil pump, etc etc.

 

Which do you think i would be better off building a 2.0 or 1.8. im aiming for 200bhp but it needs to be reliable coz its my day to day car. Aswell as a zvh conversion what else do you think i will need to see 200.

 

If you have a Zetec Bottom end why not just use the better Zetec head!!


Its Pointless machine work to put a restrictive CVH head on it

Even if you have the best CVH head you could buy (say Ł800)

A std Zetec head would be almost the same which costs Ł50



It costs less to put a better, bigger, head on the Zetec block.

 

what i was gona say

 

so should i make a 1.8 or 2.0 zvh

 

There is no substitute for CC.

Its going to cost exactly the same to build a big CC engine as a smaller engine.

The 1800 allready has a few parts you need which might make the cost a little lower due to the oil pump and water pump + Sump internals.

Ive said enough anyways...back to work

What a stupid statement to make on a topic about a forced induction engine!

 

Thanks for all YOUR input on the subject!

My point is! If your getting an engine built.....Why bother building a small CC type if the bigger CC type will cost the same! + you will get better results for same money etc etc...


Instead of reading the topic and posting something worth while you would rather sit there and pick out words and phrase's trying to turn peoples words into somthing its not..



Big up the helpful people like you on PF

 

I only pick holes when they are there to be picked.

It's not like I attack bit of advice everyone offers on here is it?

You want me to be helpful to the topic poster? Hows this...

Joe90, ignore ANYTHING anyone tells you about larger capacity forced induction Ford RST engines. Unless it comes from someone who knows the ins and out of why the Zetec based engines are not ideal unless the basic geometry of the engine is changed. Zetec and CVH heads are another story....

 

What you think i would advise Turbocharging a stock Zetec

Tell me what CVH engine you know of that could produce the same amount of power as this Zetec with the same amount of boost?

 

To make a good Zetec engine worth turbocharging, the crank and rods are scrap to start with. The head needs to be ported. They are not a free flowing as you seem to think they are.

Irrelevant. Why that Zetec? Why is it so special? Do you even know why they apparently produce more power than a CVH for the same boost?

 

I think jano knows his stuff mate, why would you pick a 20 yr old 1600 that runs the same power at 8psi as a standard more modern 1800 makes in n'asp form? if you're going for big power with the cvh you're gona end up making expensive changes to the bottom end anyway, so do it with the bigger lump. if you run the bigger lump with the same boost you'll get more power per psi anyway, as more air and fuel are being forced in to an already bigger combustion chamber. It's nice to be nostalgic and have a cvh that can produce good power, but it's hardly the way forward.

Obviously with forced induction the restrictions of port and valve sizes are less significant as the air is not relying on the induction stroke of the piston to pull it in. So as the valve area is much larger than that of a cvh anyways, headwork on a zetec will only come into play once you've already got a nice power curve and when you want to improve off boost driving too, so you'll be spending money on your cvh head long before your zetec.

 

Do you think I am posting for a laugh and a wind up?

Why do you think I posted what I did?

Just because I am not a pro tuner and don't post advice on enignes very often, does that mean I know fuck all?

All hail Jano, the tuning God. Bow down in the presence of the almighty Jano.

What do you know about the rod ratio differences between the Zetec and the CVH?

Do you know why this ratio makes a difference in how the engine creats it's power and why it makes a difference to how the engine lasts and creats power as well as stresses on other components like the gearbox?

Do you realise that a standard Zetec head is only marginally better than a standard CVH head in terms of CFM air flow?

P.S Zetec based engines do not produce "nice" power curves unless money is spent on bottom end alterations.

 

ERRRR did you not read the bit where it says
I will say it agian just incase you missed it the other 3 time.

We have just said that Turbocharging a Stock Zetec is pointless, now after we have made that clear your still talking about it.


Daz your such a piss taker! Why dont you post on a thread where people want to listen to you..

 

Daz the expert

 

Daz seems a very clever chappy
Must ask for his help all the time as seems to know alot

 

So Jano, every Zetec engine you build, what do you advise the customer to do?

 

Dont try and worm your way out of it now....

If your so intrested in what i advise customers to do, you would do the same as many others and have a read of my forum.

What i do, is what i do.... But hey im no expert compared with the likes of you. I spose you have an MBE and a degree and masters in summin or another

 

LOL

You tell him Jano
Sounds like he knows every thing any way


What an expert

 

Worm out of what?

I asked a simple question....I have no intention of registering on a forum to never use it.

Why bother giving only half the advice about the Zetec engines? Zetec engines are pointless unless stupid power figures are required, IMO from the research I have done.

What does my proffesional qualifications have to do with anything? If you must know, I am a mechanical, electrical and software engineer in the automotive industry.

What that has to do with a Zetec or ZVH engine I have no idea!

 

Shut it

 

 

jano is the man that can & ive been on his forum and its full of useful info plus i think that he knows what he is on about as the cars he has built prove this ...

 

Tell him jano

 

Can't even have a proper discussion/debate without it turning to rat shit!

 

Jano noes his stuff he gives sound! advice

 

for fooks sake whats all this go on jano etc you ass licking fookers he might know his stuff and no doubt he was helping but so was daz just because they had different views doesnt make daz stupid does it

 

i think he was referring to the question asked, should i do a 1.8zvh or 2L zvh.

and i agree, whats the point in doing a 1.8 zvh when you can do a 2L?

 

Obviously it does!!! Must be by pure luck that we have 2 cars here spanning nearly 900bhp combined!!

DUDE, the 2 litre will always be a better engine to go for out of the 1.8 and the 2 litre when doing a cheap conversion as there is more parts. The 1800 is restricted in making reliable performance by the rods and the pistons. If you was to go for a big power engine where the crank rods and pistons need replacing, then at this point capacity is irrelevant. The difference being that the Zetec based engines will need crank, rods and pistons to match the smooth power curve of a CVH, where as the CVH will only need rods and pistons.

 

The immediate point that sprung to my mind when the Zetec turbo was mentioned, was:

Where is this chap supposed to find the extra cc in the cumbustion chamber to be able to run a safe turbo setup on his (probably) standard S2 management?

Sure, a Zetec turbo is a good engine. But this guy is on a budget - he probably does not want to buy new pistons and rods. So his best option is a 1.8ZVH, proven to run and produce good power with just a CVH head, without touching the pistons.

All he wants to do is have a bash at building a ZVH - without complicating things the 1.8 is the easiest and cheapest to do.

So lets all calm down - everyone who took the time to post about engines in some form or another has made some valid points, the rest of the people who have posted here really must have very tiny minds - still they made me laugh.
