Hey,
Are the 1.8 20v and the 1.8T Engine Bays the same. So that an induction kit for one would fit the other?

1.8 20v/1.8T 20v Engine Bay

I'm not sure.
1.8Ts are configured to pipe air into the turbo at the back of the engine.
I think 1.8 non-turbos will be piped to feed air to the inlet manifold at the front....
Here's a photo I took a while ago of my non-turbo engine bay, its quite close up but you can see the pipe coming off the airbox at the top right corner. Any thoughts on induction kit compatibilty?? 
The airbox is just out of shot.
Looking at that, I'd say the airbox is smaller than LC (with the MAF further towards the nearside wing by maybe 2") This would leave you less room for replacement induction / filter.
You would also need to check your MAF outer diameter - if it's 70mm then you haven't got a fit problem on that.

Cheers, I've been thinking about going down the replacement filter route (i.e. Green or similar), rather than a full kit anyway but its interesting to know the differences between the engines.
But while we're on the subject, does anyone know anything about VVT on the later engines? I read that this was an update - mine's a 2004 model and has a definite step up in the 3.5-4.5k rpm range (showed up on rolling road results to confirm)... if the engines do share a block, then I guess I could confirm this if I have an AUQ engine code? Haven't looked as yet to be honest...

AUQ is a 1.8T engine code, it is fitted with a form of VVT, but it is only used at startup. When activated, the engine runs with massive valve overlap, the intent being to draw some of the exhaust gases back into the cylinder for reburn, resulting in a cleaner exhaust gas on cold starts.
If you've ever heard a 1.8T start from cold they can sound 'rough' for about 30 secs, this is when the VVT is activated along with the Secondary Air Injection.

So this would mean not then. Thanks for the help
