How bad of a job is this to tackle?

Airbox off, grommets out, turbo bolts and simply change or am i hoping too much?

not done it myself but looking at the manual the only extra steps it mentions beyond what you have said is moving the wiring harness next to airbox, removing the exhaust front pipe, remove the turbo intake fron airbox - i guess all for access.
snap shot from manual below showing some of the turbo fixings.

Hmm. Thank you for that, very useful. Maybe it is a job i will tackle myself afterall. Do you know where a gasket may be available?

advanced factors have the part here:

or you can create a topic in the site sponsors section if you wanted parts from Dan @ duckworth.

Thank you, i've ordered one. Access makes it seem a horrible job but hopefully i'll be pleasantly surprised like with the starter motor!

EDIT: just realised i ordered one for a P38 due to the fact i just googled the part number - hopefully they share the same pattern (the pic looks identical also!)

I don’t feel too guilty linking to the competition as I’m always sending people over here.
This might help, I have had the turbo off at least 3 times I think.

Thanks, shame the pictures are down but I'll have a good read.

I added some pictures further down because the original ones were missing
