Well, removal was fine, no problems there. It was getting the new one in that turned into a bitch of a job. For a while I thought it just wasn't going to go. When I did eventually get it in, I realised the mounting hardware wasn't lined up right - there's some degree of erm adjustability on the brackets etc when you bolt them to the IC.
Also I couldn't get one of the bolts lined up on that Active Spoiler cover thingy that you mentioned, and then it was looking like the lower rubber hose could've done with being longer.
and then ( ) I had the usual fun of fixing the undertray in place with all the sheared off bolts etc. This is my second Supra and my last one had half of the undertray bolts sheared off too.
All this with 500watts of heat pumping out of my shitty inspection lamp (ok, it's a garden flood light on a wire )
Anyway, all done. The car feels like it has more of a kick when no2 turbo comes online, but that's possibly a placebo effect. I didn't do it with the intention of gaining power, more for peace of mind regarding engine safety.
I'm very grateful for the guide BTW, I didn't want to seem unappreciative. I was just having a sarcastic moan that's all
