There are a few ally spacers, brackets on the engine and the plate mounts to that.
Some of the pulleys are just mounted to the face plate so they will move under load.

Slack bearing when under load / heat somewhere causing the pulley to 'wander'?

I've ignored the belt and fitted a wideband O2 sensor 
Basically these are a more sensitive/accurate lambda sensor designed to identify how the car is running - lean, rich or OK. Lean is a possible cause of the last engine getting lunched so a concern
as you can imagine
AJ recommended fitting one
before we tweak the map
The AEM kit i bought came with a gauge i need to mount somewhere, its just wired in for now.
Needs calibration and a link to the AEM EMS (one wire)

Indeed, no boost is one thing but a fried engine is more terminal.
Pillar gauges look nice, especially low down ... alternatively, tucked away on the corner of the dash between pillar and screen is also reasonably unobtrusive - can't stand those gash dash mounted blobs.
Think i'd want 3 though ... oil temp, oil pressure and your AEM gauge.
Alternatively, what about using something on a smartphone via bluetooth from the diagnostic port?

Yeah, last pic on my first post. Real shame as it was a 39k miles motor but the new one seems good.
Ray found a few faults, badly fitted injectors had ripped the seals and at least one coil pack was dodgy but ultimately no wideband sensor means no reliable AFR feedback to the ECU and the driver cant spot an issue

Wideband can be a useful thing to have for this type of thing. One of my biggest worries is a fried injector killing a cylinder.
On the other hand it's not always necessary, most factory SC / FI cars don't use them. What's better is having some failsafe's set up in the ECU, like safe mode for detected knock / afr.

A well seasoned tuner/mapper shouldn't rely on the OEM knock sensor. Some of the harmonics of the engine, the OEM can mis-interpret as knock.
In ones humble opinion, the widebands and gauge is a good visual aid for those who haven't heard knock or pinking. Particularly when running forced induction.

Well.. Belt back on but i stopped at trying to put all the bolts in and idler pulley . They are all little bastads who nip my fingers and stuff
It all seems to line up perfectly. The bearings in the pulleys all nice but i did notice the charger pulley is stiffer than i expected (having never played with one before) though it feels fine
She'll be back together this weekend with the wideband wired to the ECU and a gauge for my sanity
