And it is a complete b**tch of a job?

Car is an 02 STi Type UK, so no cat in the up-pipe which should make life easier.

The heatsheild on it has fractured at the turbo flange and the rattling is getting on my nerves http://bbs.22b.com/ubb/frown.gif

Take down pipe off, undo 5 studs at top of up pipe flange, 2 on downpipe side of turbo, 3 on inlet side of turbo.

remove 2 bolts at bottom of up pipe, after you have removed the shield around the drivers side header (4 bolts IIRC)

Loosen engine mounting bolt at turbo side (dont take off, just loosen to near end of thread), jack engine up at that side, slide up pipe out.

Thanks Steven, great stuff http://bbs.22b.com/ubb/smile.gif

I can do the down-pipe... the rest dosent sound to tricky.

My only concern is the engine mount. Is there a specific torque I should tighten it back up to?

Cheers,

James.

Don't understand the engine mount thing - I was told when fitting Maxim headers (one piece header/up-pipe) that I'd need to do this. You don't with the Maxim - and definitely you don't need to to remove a 2 piece design.

Or is that just on LHD cars? http://bbs.22b.com/ubb/smile.gif

Getting out the OE pipe is the problem, it's really tight (it's got that nasty heatshield remember?) - but mine came out without lifting the engine (which is really easy to do anyway if you'd have to).

I get the impression there is confusiong between up pipe and headers.. looking at the other post of James also etc..

Nope, no confusion.
I am refering to the 12" item that goes from the headers to the turbo that on WRX's would contain a cat, but doesn't on STi's.

On my car the heat-sheild around the up-pipe should be attached to the turbo flange, but has broken away. A common fault on cars with aftermarket downpipes http://bbs.22b.com/ubb/mad.gif as there is no longer a lower turbo heat shield for the up-pipe heatshield to bolt to.

James,

Found the scoobymods thread all by yourself did you?

As I said in the SNet thread, I did mine when changing the turbo so just pulled it out upwards.

No worries mate http://www.pistonheads.com/include/images/cloud9.gif

I've decided in the end to take the car to xtremescoobies (http://www.xtremescoobies.co.uk) for the work as its the 1st time and im concerned about seized bolts etc etc.... They are local and offered a great price http://bbs.22b.com/ubb/biggrin.gif

Still, this is great info for future reference!

Cheers,

James.
