was just woundering if any body knows is it possible to use the 1.8 zetec engine from a 1997 escort gti to do a zvh or do i have to use the 2.0l silver top mondeo engine cheers greg

 

to do a 1.8 ZVH u use a 1.8 engine to do a 2.1 or 2 litre u use the 2 litre one!

 

so is it the same to do we have done the 2.0l befor its just that i have the 1.8 gti engine here already and is the standard block and internals just as strong as the 2.0l cheers its just i have been told its hard to use the 1.8 and not as strong

 

the 1.8 pistons have a thicker crown so they are stronger infact. its easyer to build a 1.8 zvh than a 2.0 as you can use a standard head and standard cvh head gasket

 

Only differences i have found out in the past week is that the 2.0 uses stronger rods and the block itself is stronger allowing the conversion to chuck loads of abuse at it. The 1.8 is also very sufficient for the job in hand. Thats what Im having done to mine within the next few days

 

the 1.8 and the 2.0 silver top blocks are the same mate the 2.0 is boared out version of a 1.8 so less metal = less strenth its not rocket sicence the 1.8 is stronger

the rods same agan im afrayed the 1.8 and the 2.0 shair the same rods

i must add tho the standard 2.0 block will take 500bhp with out any problems

 

Well there ya go, learning something new every day on here!

Silver top, black top, friggin multi-coloured rainbow top, its all the same to me... sorry.

 

so what your sayn is i wont need the de compression plate for the 1.8 standard block just use a 1.6 cvh head gasket and streched head bolts and jobs a good un

 

nooooooooooooo i wouldend use streched head bolts i would use strech head bolts or zvh head bolts you can get them from burton power

you still need to lower the compression either a decom plate as you said or i would remove the pistons and have 0.5 skimmed off the top as its a 1.8 zetec it bhas thicker crowns unlike the 2.0 where skimming is not realy advised

hope this helps

sorted decom plate it is then just tryin find as much out as i can for this one as this is my only car and i have a week to strip it and builld it so hopin for no probs gonna start gettin all bits in next few weeks then get it sorted haha

 

good luck with it and get some pis up

 

quick question what is the best way to fit a decomp plate on a zvh, 2 head gaskets or seal it on to the block

 

will do mate not been started for a a good few weeks yet as soon as iam on it wil get some up

 

yea you will need to use 2 head gaskets

 

kool whats the spec

 

No they're not, the 1.8 is a very different casting. The 1.8 should technically be the stronger and more reliable block, not just because it's a smaller bore.

 

so r u sayin that the 1.8 needs more work or just that the 1.8 is stronger than the 2l one i have been told by some people that there is more work in using the 1.8 what kinda boost is safe on the standard bottom end
