Hi all, back with another question!

On looking around for a s2 I've come across a few with a 2.1 zvh turbo engine? What are they from, what sort of power and are they proper conversions or bogged in so to speak?

can anyone enlighten me?

Clasby

 

2.1 is 2.0 with calibra piston usually
and bored out of course

 

.. which infact are actually 2L as 2045cc is 2.0, not 2.1!

 

I thought that but it could be a shorter piston giving a little more stroke making 2.1??

 

So is it originally from a focus? then a turbo conversion?

 

Or Mondeo

 

Just to make it crystal clear, ZVH is a hybrid engine that you get when you use a 16V Zetec bottom end and a 8V CVH cylinder head. So it's more like a large capacity CVH.

... and at the shorter pistons

 

Yeh, ZVH is Zetec bottom end and cvh head.

 

I see, cheers for clearing that up for me.

 

speak to www.powerconversion.co.uk they know all here is to know about zvh's

 

the power you get out of a ZVH by large depends upon the management and boost you are running,

The engine make little sence to me, I fail to understand why FWD people think its a great idea to pull off a decent 16v head and replace it with a 8v head which flows less.
You don't get the cossie boys pulling the 16v head of the YB to replace with the SOHC from a 2.0 pinto do you

 

Mega Torque

Initially was much cheaper to build a ZVH over a ZT. Prices have evened out over last few years to where its pretty stupid to go 8v...

Can't knock a ZVH though, had them in 2 of my Escorts and they both flew

 

that's why you can knock them to pay money to make alterations to replace a head which comes with the engine for one which unless extensively ported does not come close seems odd.

Ive driven a number of ZVH's and don't think they are a touch on a well built CVH which revs a lot nicer imho

CVH or Zetec are the only choices imho,

 

The crank dictates the stroke, not the piston!

 

A well built CVH is pricey though, fair enough they can really rev but won't touch a ZVH for torque....Or power pound for pound.

I'd build a ZT now given the choice but would deffo still buy a ZVH'd escort.



BUT money no object it would be a all steel CVH hands down
