64mm TB mounted on spare inlet, oddly it's off centre compared to the Renault unit - would have thought an even 1mm all the way around! But not much material to remove from the inlet and fortunately the other side is flush. Just need to now mount it on the car and confirm the wiring works - then I can get the whole lot ported as one. I am a bit on the fence though as to using this BMW one or buying a 64mm ported Clio one :\ An advantage to using BMW Vs. ported Clio 64mm TB; to replace a Clio unit it's £120 on eBay for the ported 64mm item, and no guarantee the machining is good/butterfly is secure etc (probably no real concerns there though tbh). Whereas replacements for this BMW item though will be £20-£30 and def no concerns with manufacturing. ?? Would probably want the butterfly knife edging on the BMW while it's all being done.
