Hi guys

My missis has a 1999 mk1 focus 1.8 and now as i have a track car she wants to change her focus from a show type car to a show/track car so wants more power.

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

Adam
