those flappers do tend to be pretty loose and rattly (although when shut they should be held tight against the wastegate ports). It looks like your motion ratio for the actuator might be pretty massively changed from the original design (I guess you clocked the turbo but couldn't move the actuator to match?), keep an eye out for boost creep because the wastegate may not fully open.

Havent had much time lately for the car. Trying to sort it out for the cert, but we just had a baby - 2 months old now. Bit annoying that it isnt drivable on the road at the moment, but at least we have another car for family stuff, and I use an e-scooter to get to work anyway. Will probably be able to get back to it soon.

I at least mounted properly the relay panel. Im going to see if anyone has an issue with it before I replace it with the new one, as that will take creative rewiring. Looking for time savings right now. Then replace the turbo oil drain with a more appropriate line, mount the starter button somewhere, and strap down the battery. Oh, and I did some investigation into the low voltage condition, but nothing solid turned up yet. Might just replace the alternator with the known good one that I put on the 20v engine. Oh, and a misfire has reared its ugly head, so thats another annoyance to figure out.

Slow going at the mo.. Hoping to get things sorted out for summer though.

Fixed the "misfire" - was actually the ECU triggering fuel cut due to overboost protection set too low. Bumped it up 10kpa and its running goooooood! Good god, its a freaking rocket ship.

Low voltage issue has largely gone away for now after I raised the idle - itll do for now.

Nice. I can't wait to see this thing on a run Cameron. Saw it in your garage a while back and I imagine you'll be a very happy chappie once you can get in there and give it the hiding it's begging for. An AW set up right handles so well, and one with some serious power would just be the shit. I'm kinda jealous... :mrgreen:
