I know loads of people are running zetec turbos so should be easy but i was wondering how strong is the standard 1.8 engine and can i say put 10 psi through it without it going bang? Or would it need a the comp ratio decreasing?
Alternatively would it just be easier to dump a 2.0 zetec in and turbo that? Are they any stronger?
Trying to do something cheaply but got to be good wnough as its uer daily so needs to be reliable.
I no people say reliability is alot down to mapping but it always needs a good base.
Any help welcome.
Thanks

Speak to Dale at Bailey Performance. He has done plenty of zetec turbos without lowering compression. When i was having some mapping done he was telling me about it. He doesnt go mad on boost, and the key is good mapping and good intercooler. i believe he gets 250bhp ish from a 2.0 so he should get good power from a 1.8 too.
in fact .... here you go

He mapped my zetec turbo mk4 fiesta and hes a really good guy.
