Latest issues on newly purchased MR2 Turbo 1993 - no boost, power steering, more, more

Hi,
I have recently purchased a Rev 2 1993 and looking for any thoughts of trouble shooting or idiots guide to the below;
 
1. No boost.  Vac at 20 but wont boost.  Rattle when accelerating.  I did not have this problems previously.  Work done recently; new silicon hoses, new timing belt and timing tested at 10, reinstalled intercooler & piping, detailed very detailed degrease / clean with high pressure washer.  I can not hear any air leaks (rattle is very loud when accelerating however not there when no acceleration), vac needle moves only one or two numbers from vac 20 but no further movement than about 18 vac and no boost. Removed piping and checked turbo for any shaft play however no lose movements.  Spun turbo and no noises from turbo when spinning.
 
2. Power steering motor runs continuously when power steering power is connected.  If the car power is removed and the power steering power cable connected it turns on all dash lights as if the car is on (about to be started).
 
3. What is the recommended height of an MR2 turbo and where to measure?  The car has coilovers and looking for what is best to set the height at.  The car has 18" rims so looks full in the wheel arches.  Is there any benefit to having the front of the car lower due to the weight distribution from front to rear.  Any advice or guidance is greatly appreciated.
 
4. Has anyone installed a Mongoose M80 alarm with turbo timer in built.  It mentions to use immobiliser circuit one to connect to ignition sensor wire and immobiliser circuit 1.  Does anyone know wire colours to what it is meant to be connected to or what to test the wires for as I dont understand the diagram.   I will try calling Mongoose however thought if anyone know please share.  
 
I would normally just go to a mechanics however the car is unregistered in Mildura (long storey) stuck until the car is up to road worthy.

Cheers Carmikey.
 
UPdate... found the front engine mount had half a bent bolt in the bottom and no bolt in the top.  The side engine mount has a rod on the rear side and rubber/bushings that was not tight.  New bolts and tightened - now no noise. HOWEVER... still VAC sits at 20 acceleration at times will get the needle to move to about 5 VAC however mostly does not move from 20 VAC.  What does your boost gauges show for VAC when at idle ?
 
Also the idle is at 1500 and will not lower, I have tried the adjustment idle bolt at top of the throttle body and the adjustment of the sensor at the side of the throttle body.  Any ideas, anyone to any of it :)
 
Thanks

no boost may imply the timing belt has been installed wrong.

Alarms are typically black wired with tags, removed by the installer, to increase security and annoy anyone who has to work on it later. The circuit board ...may... have indicators.
 
M80 has 3 relays and immobilises whichever circuits the relays are connected to. Ignition is 1, controlling the turbo timer.
2 & 3 (if used) are usually starter, fuel pump or some other electric circuit.
 
Depending on installation, other inputs could be voltage drop and Normally Open (N/O) or Closed (N/C) switches and outputs to horn, siren, dome light, indicators, door locks and boot release.
 
What are you trying to get it to do?
 

Usually done on the wire coming from the ignition barrel that livens up the ignition (& red lights) on the dash. You cut the wire and interpose the M80, so the engine still runs after the key is removed. Personally I'd wait until other problems are sorted. Just let the car idle for a bit, if you think the turbo is going to be that hot.

It will run for a bit when you turn the car on but then will stop if its just sitting there.
20 seams ok
If it was the TPS (throttle position sensor) you turned it will need to be reset.
Is the 1100 rpm when its cold or warm? The accelerate cable cable could also be to tight and holding the throttle open.
 

Vac of 20 seems pretty normal. Some people see 21 or 22 as well.

Glad you got some more issues sorted.
You should update this thread with what you did to solve the idle and boost issues. It might help current and future owners solve similar issues.
