rear sub frame, as it was bent in a crash. Also the rear arms were replaced as these suffered damage to. Was not boosting, issues with wiring, ill fitted dash (boost gauge, lighter, head unit and more). Was quite a mess behind the dash tbh. Also re run power feed for the amp as it was untidy and also dangerous. Replaced and cleaned up a lot of the piping in the engine bay due to oil ingress and perishing. Checked the turbo's over to make sure there was no unwanted play or damage.
Was quite a lot to do, but the car feels and sounds completely different now.
