What year is the car?

If it's a year that does not contain "the black box", this guide will be close to what you need:

Just scroll down and you'll see the recommended sizes and lengths.

I found that exactly half of the Hose Techniques kit was what I needed. Keep in mind though I was very thorough in avoiding waste - I measured the old line and cut the new line to match.

FWIW, I took pics and did a writeup. www.davidgeesaman.com

Coolant hoses aren't the same as the silicone vacuum hoses. When people talk about silicone hose, they're usually referring to the vacuum hoses. You can get silicone coolant hoses, but less common. IMO just go for OEM coolant hoses. They'll last another 5-10 years.

Vacuum hoses cause annoying power loss problems when they fail. Coolant hose failures cause an immediate overheating issue, so kudos to you for planning on doing all of them. You can find info on cooling hose replacement by searching.

IME, the coolant hoses are not in quite the same places as the vacuum hoses. There is some overlap (near the turbos) but mostly not. The exception is one coolant hose that runs from the engine block to the throttle body, and is best accessed during the vac hose job when the solenoid rack is out.

well if ya aint got nothing better to do i got another question for you,the cat is fooked on the fd but i need 1 for it to get through the mot,so i was just gonna put a standard one on just for that then take it off again and put a straight through pipe in,i guess this would be ok and the fd would run fine? yes/no?

If you can get an old FD cat, yes, you should be fine on a stock setup. Don't go straight pipe (on FDs, 'Midpipe') until you have a plan to monitor boost levels. Midpipes can change boost patterns pretty significantly, and changes in peak boost will blow your engine. Check the newbie sticky thread for details, and run some searches for even more info.

I don't know the details of the MOT, so I suggest searching in this forum for 'passing emissions' (in the newbie sticky thread also), or posting in the UK/Europe regional forum. It's a common issue.
