Ok, so you have already had it installed and running once ?

Thats a little differant, I was under the impression you had a bunch of random parts that where in theory good for 400+ bhp.

i play with zetecs a lot, I’ve built a few turbo set ups but I am no expert and mine are all at the budget / diy end of things.
I work on the fact if it works for the manufacture it will work for me.

if I google your turbo, Case tractors come up ? I’ve never heard of it in a production car but there are very few production cars of zetec age running 400 horses.

I mention the Rs a lot because I work on the principle if works for Oem it will work for me. It doesn’t mean it’s the only or best way to do things but it does all bolt together like Lego.
I wouldn’t let that sway you into swapping out what you have .
