Its a completely standard half-arsed jap spec CA18det, other than an air filter. Jap spec engine was swapped in 60k miles ago apparently. I have yet to find a single mount or casing that has all of its screws; none of the ancillary hangers or mounts are connected, one of the bolts on the inlet side engine mount is missing, there was a bolt missing on the turbo elbow which probably contributed to what felt like a boost leak, etc etc. Now these wouldnt have contributed to the failure but its worrying, because if whoever swapped it cut corners on simple stuff like this, what else have they cut corners on?? Will put pics up in a bit just for reference anyway. So far i have removed the breather pipes that go over the cam cover, the turbo elbow and the turbo heatshield, so not much progress.
