Hey folks whats involved and what do i need to do to the zetec head to make it suitable for a turbocharger? ive bought a 2.0 zvh but the head is standard so want to put it back to zetec

valve springs and thats it mate


u may unmodify the block if the oil returns have been blocked but thats easy enough

Ok mate cheers

no probs if you buy valve springs from area six ian also does a shim to go on top of the spring to add extra force if u want to run big boost

Good stuff, il keep that in mind!

What about where the block has been modified for the tensioner and the water pump?

thats easy remove the plate that been bolted for the water pump and bolt the standard water pump back on and remove the cvh tensioner

if the holes have gone into the water way which mine never then chemical metal them

just remembered make sure you change the crank pully back to a zetec one as there is one less tooth on a cvh crank pully and ull bend all your valves

what about the water pump and hoses ?

Also does the zetec head still require a cam sensor? like the cvh head does?

im not sure mate never used t2 i know peoplehave used t on zt before tho im preatty sure u can use the standard zetec cam sensor but dont quote me on that i know that you can with omex

You'll have to check the compression ratio as well as the combustion chambers on a CVH head are bigger than a Zetec so if the compression ratio is already highish for a ZVH set up, it will be too high for a zetec turbo. Alot of people had this problem when they started using Acrilite pistons for ZT use as they were origonally designed for ZVH use.

mine currently has calibra pistons, are they the better suited ones for this application ?

muz

For ZVH you should really use the early C20XE pistons which are N/A pistons, but high quality pressure cast Mahles. Can take 5-600 BHP. The serial number on the bottoms starts 86P

C20LET turbo pistons (also pressure cast Mahles) are better for Zetec Turbo as the compression ratio is better. LET pistons in a ZVH usually gives too low compression which makes it laggy.

im pretty sure they are let type, which explains alot. Ah well another excuse to push ahead with a full zetec

Rather than starting a new thread, I thought i'd continue this one.

Currently I have a zvh and going zetec,

I have the adapter plates for the exhaust/inlet.
have a fiesta inlet
pectal management.


What other bits are required?
*what water pump/from which model (2.0 zt)
*what oil pump?
* Pectal has a coil pack, can i bolt this straight onto the zetec head?
* any issues with water pipes and re routing them?
* am I right in thinking the st170 headgasket is fine?
* Will any oil pipes require changing?

Cheers guys

just a quick, have a chat with crazycage off here, was a customer of ours but now is a good frind and helps out with a lot of work, he can fab the inlet and exhaust, check out my build thread in the resto section, even though its a zvh build he makes the zetec ones as he has made the ones on his car and on ricks of here, both well in the 300's

just food for thought mate. Keep us posted on your progress and if you need any help just holla

cheers raj, looks good on your motor! i think for the moment I'm going to be running the fiesta inlet and current exhaust. however saying that I most probably change my mind! lol

cheers
