I guess because at the same BHP, a ZVH will have a lot more torque while a Zetec develops more of it's power by revving.

 

that all depends on the turbo and cams used, a t25 on a zetec with standard cams would be torquier than say a zvh with wild cam and a big t34 at the same power, unless im thinking back to front?

 

Right guys, iv got to working on the head now. If I remove the valves to clean everything fully, and I want to replace the springs, can i use the original valves and follower caps? Will I have to lap the valves in of not?

 

Sorry to go over old ground but a ZVH Turbo will give a totally different driving experience to a Zetec Turbo. Grab a ride in both if you can and make your own mind up to how each would suit your driving style.

I comes down to what characteristics you want out of an engine.

Personally I went with a ZVH, I love the torque delivery then a smack in the face when the boost comes in.

 

Just for ref - the Noble uses a MT285 6 speed (ST170 box with longer ratios) not the MTX75 5 speed.

Simon.

 

Right in that case, anyone got a zvh motor and anyone got a Zetec t who lives in south east, north Hampshire or close?!

 

And would you be willing to meet up? Cheers. I'm kinda thinking still go for the 16v and then go with cams, mapping and turbo setup to try get more torque. I want to use the car on the road and track. I'm not after massive power. But drivability is a key issue. I don't want to end up with having only top end power. But I don't want to have just torque and the power tailing off 2/3rds up the rev range!

 

if you drive upto cheshire ill let you drive my zetec turbo but be warned you will want one after a go of it.

 

Cheers for the offer but a little too far, thank you tho. It's a good 350mile round trip

 

Right guys, another tech q! Can I use a 1.8zetec ecu for the zt conversion? If not then y? If yes what would I need to add or change? Cheers
