I guess I should update this:
Some solid hours from 'two mr2's' (Pete) and a little bit from me finally got this up and running good.
First up was a simple oil change on my part, and Pete setting to work on the broken/snapped/twisted/screwed window regulator. Normal oil change turned out to be a b*tch, NA is so so much easier!
Previously was throwing up fault codes, going into limp mode, could hear turbo spooling away but going no where and all round drove like an absolute pig.
Repaired the dicky spark plug lead and disconnected the (what looked to be a jammed open) manual boost controller and put it back to stock. Its my first turbo car and I (should) be happy with stock boost settings.
After resetting ECU, managed to fault the Knock Sensor (code 52). Replaced with known working one from an early Gen2
(to my suprise, even tough both are rev2 mine being a 93 had different wiring colours to the earlier rev2) and fired it up and burbled away nicely for first time.
Next was to inspect wheels, the SSR wheels turned out to be (as I figured) non staggered
17x9+22 all round. As I found, most common sized wheels found on 32GTRs not a SW20!
Replaced with non staggred 15x6.5" supra wheels temporarily till I decide what shoes I want to put on (Enkei RP01, Work Meister S1s or the RPF1s i've been hoarding)
Took it for a drive, engine was driving nice and strong - but mechanically far from decent. Backing off the power - whole car sways, steering is vague an brakes need replacing. but all in all, quite happy
Also discovered running a whiteline adjustable rear sway bar! Score!
And because we love pics (well i do at least

)

My 2 MR2's and Petes 2 'MR2s
Pretty sure order:
GT (AMP)
G Limited (AMP)
GT (SMG)
G Limited (uh...)
