So from underneath then? All videos ive found have gone from top but theyve always  been different model cars!  Cheers, will get it on my ramps weekend hopefully.

I know you can get the 225bhp ko4 from the top. And probally the aum and other ko3 turbos aswell.
Looking at the downpipe id go underneather. Last one i did was in a mk2 golf and had to be done from through the drivers wheel arch. As soon as there cracked off they normally spin out pretty easy anyway.
Have you got a lambda socket or are you using a spanner
