Thanks for all the info guys, I went quite for a while having a think and finally came up with an option.

Today i bought myself a wrecked 225 (BAM engine) quattro audi tt from Milperrra Pickles Auctions and just towed it home.
So now i have acess to a lot of the stuff i need. However, i think im creating more problems for myself in the meantime haha.

I was thinking just straight swap in the bigger MAF, injectors, dual intercoolers, the K04-022 turbo and manifold etc and then go get it tuned. This was why i bought the wreck as i got the whole car cheaper than all the parts i would have needed seperately.

Next i thought to myself "But quattro" so i might as well do a full engine swap, swap in the quattro (If its possible to mount it up to non quattro), ECU, everything into my working car and then pray that its happy and turn the key.

Or to add in some more thinking time.... I keep the wrecked car and swap bits into it. It came from the auctions as a WOVR N/A which I think that means i can register it again without having to pass a detailed write off inspection. However, this means getting a whole new dash (airbags went off and ruined it and the steering wheel), swapping in a new front end support brackets, Fenders, bonnet, new headlights, radiator, aircon radiator, various other bits and peices and one of the side mount intercoolers, then reset the computer etc. This is all if the frame isnt bent underneath and the engine isnt ****ed as well (which it doesnt look like on a quick inspection)

I only got the car today so ive been doing a lot of thinking but theres definitely some fun spanner spinning to come. Would welcome anyones thought or ideas

Cheers all!
