[QUOTE="singlespeed, post: 24430, member: 264"] Nice one Fredi. I have just had the airbox and intake pipework off, to see if any fettling was required to the plastic.They were a higher quality than my old Vauxhall astra, but still some room for improvement. Ended up spending some time with the dremmel and then 150, 300 and 800 grit sandpaper to remove the dips and ridges from the mouldings and also rounding the edges where the tubes join into the rubber hoses and airbox, ready for some silicone hoses and BMC pannel filter Whilst the airbox was out of the way, I had a look at the TB and found that there was a step (aproximately 1mm) at the bottom of the manifold. Slackening the 4 mounting bolts allowed me to lift the TB as the mounting holes have some clearance around the bolts, so there is no longer a step to the incomming air. Obviously the TB shouldn't have a step where meeting the manifold as it is 2mm smaller ( i measured 67mm and 65mm) , if it was mounted centrally, but the mounting holes must be off center Rain then stopped play, so it was all quickly re-assembled :evil: Anyone know if theres any bolts hidden at the back of the upper inlet manifold, before I try removing it next time :?: How does the intake scoop come away from the slam pannel :?: [/QUOTE]
