Leon mk1 1.8t decat pipe

[BurnyZS]

Basically my downpipe has snapped off on the welds right by the flexi/turbo so I'm looking at decat pipes rather than a new downpipe/cat.
Is a mk4 golf gti 1.8t decat pipe the same as a leon mk1 1.8t? I'm thinking yes but need confirmation first please.

[BurnyZS]

What about lambda sensor and EML?

 

[nd-photo.nl]

Buy an Lambda O2 spacer and you will be sorted.

 

[nathan_20vt]

Do they work? Would I notice much difference with a downpipe and decat without a remap?

 

[DannyJigg]

Slightly faster spool, different noise and maybe a shift in where power comes in. That's about it without a map

 

[nd-photo.nl]

Yes it works, and noticable difference, even without remap.

Hmmm may keep my eye out for one then on the cheap

 

[BurnyZS]

There is 2 places for the lambdas. Fitted it today and took all my boost pipes off while I was there to check for a boost leak which I have and iv found there is oil in the intercooler which makes sense so I'm going to start prepping for new turbo. Is it the k03s on 1.8t Leon ? Iv ordered gaskets for oil feed/return coolant feed/return washers. All manifold and turbo gaskets. Anything else il need bar the turbo?

There's the 02 spacer. Very cheap

a small amount of oil in the intercooler pipe work is fine, specially if its the first time the pipes have been off.

i wouldnt go racing out to buy a turbo. clean the pipework and re-check in a couple month

 

[BurnyZS]

The oil was in the intercooler. As I took the pancake pipe off the inter cooler pushed back and it all dripped out into my eyes and hair lol

 

[Azza_]

yeah there always is, the seals weep slightly, id clean and check again when you can waste of money splashing out on a turbo for no reason

 

[BurnyZS]

Hmm ok il give it a while. Iv ordered all gaskets and washers so ain't wasted too much money yet. Iv been told the turbo could be on its way out because I just loose all boost when the cars been running a while. On first start up its fine. Iv been looking for a boost leak bit can't find anything that's gonna make me have no boost whatsoever

 

[nathan_20vt]

what do you think of this? http://www.ebay.co.uk/itm/380340254055?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT

 

[BurnyZS]

That's the same as the one I used mate

 

[nathan_20vt]

Any good? Seems like a bargain. Just need the lambda spacer aswell yea? I'd be running mine with just the standard back box (removed centre box) hoping it won't be too loud
