cheecky how they do it,but who would no that has just read the basics and got them to build it,shocking that companys get away with it,but theres plenty out there that do it.

well if my engine lasted 2k and i spent 3k doing it they would replace it i know that for sure lol

Hi Grant XR,

Can you measure the diameter of the piston?
This will tell if you have a +2mm overbore ( or more)

Cheers

them pistons are from specialised engines they are called zolna pistons mine had the same code on them

Canada1

What size are the "zolna" pistons? 80mm or 82+ mm?

s24bigbhp

if i rightly remember the piston itself was 82+ they cost me £160 each. price way too much the quality wasnt that good aswell looked like cast there definatley specialised engines in grays essex the piston rings are made by hastings usa

I had a "Stage 3 2.0 Zetec" they built which was the top spec they did without going into forged rods and high compression pistons. This was thier "fully gas flowed and ported head" which I always thought was a little rough for an engine which wasn't exactly cheap!



good job it had these to force the air in

Not being funny mate, but are you saying a zvh isn't a good engine.

grant_xr

Yeah they are 82mm mate, so it is a bored out 1.8

Its not that the ZVH is a bad engine, its just thats a good ZT will make more power for similar money! Especially if you're building from scratch.
And a zetec block is designed to work with a zetec head, not a cobbled together mismash of two engines



IMO

Wow!

The way those "stage 3" 2.0 zetec ports look like,( a little rough to say the least ) a CVH head would probably flow the same.

marky_g

im pretty sure they used to import all there 1900 cvhs (they used to say on there site that there not over bored 1800s) well thats what ian the owner told me a few years back

Canada1

Hi Mark,

I certainly hope that import USA or Canada blocks were used in the past.
The block shown in this thread is a 1800 UK block overbored.

JoshXR2

what casting marks on on a 1900 block?

Keenyzs

On the website they say its an 1850cc block bored to 1905cc, they use 82.5mm, 82.75mm, and 83mm pistons.

Sorry to resurrect this post, just thought i would mention my engine has in fact cost nearer to £1200, just finished ordering parts and thats using the standard cam! so £1500 with a cam kit. You could probably knock off 2-300 for unnecessary machining, and a further 1-200 if your standard bores are good.

Machining alone came to £430, gaskets, bearings and seals came to £200 from burtons.

Hope that helps some one when rebuilding their own engine! This also isn't taking into account the 12 or more hours it will take to measure up and blue print the bottom end or the time it will take to lightly port the cylinder head, so for a good spec high quality rebuild by a tuner i can easily understand the bills some people get. I would probably charge 2500-3500 grand for an engine to similar spec.

Rob,
