HI ALL,
Just doing a zvh at the moment,Goin to the scrappy next week and i am going to get a bottom end. But whitch one is the best,2.0l or 1.8 and whats the diffrence,also what clutch and flywheel do you use and what they like on fuel ?

The black top 2 litre has better pistons (mahle) that will take over 300bhp, it also has under piston oil jets. Not sure if the 1.8 has them though.

this will be a silver top mate,what fly wheel and clutch do you use ?

I'm running a black top turbo with a focus rs uprated AP organic clutch on the standard mtx75 gearbox.

rickbartlett

im sure the 1.8 zetec has oil jets aswell

i will be using a cvh box so what you recken ?

ib5 doesn't like a lot of torque from what i've read, depends on your power goals.

xr3iAlex

is there much diffrence between a 2.0l and 1.8 ? i will be using standared ford stufff

xr3iAlex

just want it quicker than a cvh xr3i

2.0 is best as its bigger to start with, will require different pistons like 2ltr xe ones as they sit lower in the bore which lowers your compression, as for flywheel if yout using mfi then standard rst one with uprated clutch will be ok you just have to drill the flywheel holes out to 11mm iirc as the bolts are bigger, hope this helps.

Whilst your at the scrappy grab a 1.8 escort fiesta zetec sump and oil pick up pipe as you will need this if fitting into a erst.

That's correct..


The 1.8 is technically the strongest block, however the 2L block is fine at 500bhp, so it's fairly irrelevant.

Didn't know you could use XE pistons thought it was only LET ones?
On another note i have a few mates that run std blacktop pistons @ 18psi and never gone wrong.

crazycage

is that because the zetec was designed as a 1.8 ?

pa_sjo

Yeah, I guess. The 2L block has siamesed bores which don't offer as-good cooling as the 1.6 and 1.8, but like I say you don't hear of 2L ones failing, even at big power!

jacko

2l are spot on we have done loads of them

if you need any help just giz a ring i can talk you trough it all

Apparently (I say that because Im yet to try myself) the XE pistons in a 2.0 zetec block with a CVH head gives a nice and low CR, with a Zetec head, its around 8.3:1.

And the 2.0 Zetec block has piston cooling jets

jacko

only prob is getting the pistons and rods machined to get them in

might aswell just get ones for the job

what kind of CR: would you get on std blacktop pistons on cvh head?
