So finally got to go for what I hoped to be a proper drive. No such luck, my NA Rover 620i seemed quicker, and then about 3500rpm the dreaded blue smoke. Imediately returned home and the dismantling began, should have taken pictures but got stuck in. Well after about 5 hours of swearing, knuckle and head banging I finally managed to remove the stock twins. Will put some pics up later of the carnage, but the #1 turbo compressor was pretty beat up looking and couldn't get it to spin more than about 1/4 turn, which turned out to be because the turbine had sheared off preventing shaft rotation. I think this is why the car felt sluggish as the compressor was actually blocking air flow. Then got to the #2 turbo, was a little better. The compressor nut was almost completely off and the blades were chipped too. There was excessive shaft play and the turbine was probably the only decent bit of the two turbos.
Next will be waiting on the Hose Techniques kit to arrive adn then install them along with a set of the S4S GT28R Hybrid Twins along with the HKS hard pipe kit, CW SMIC. Since the bumper is off might as well sort the previous owners overspray on the AC Radiator and components in the front of that along with fitting and wiring in the active spoiler. Most likely will find something else to add to the list too.
