terrano NO power, lots of fuel, no smoke.

Yes it happens all the time,cold or hot
It is an electronic controlled IP, not sure but i think VP44, again not sure but i think Zexell not Bosch [ MAF is HIatchi ]
Nothing coming from inlet to IP, like vacum hose
Feel V unsure of myself when working on electronics, but this morning i did a couple of tests
Crank pos. sensor should have resistance of 900 ohms ,, test near enough
Timing control valve should have resistance of aprox 15 ohms,, test 1100 ohms. Prick of a thing to get at but i will try to wriggle connections, I can see it with a mirror but F%$#ed if i can get my fingers to it.
The car is a limited edition 96 R3mr R50 Aero TD27ETi , The manuals that i have been able to get hold of have different color codings on wiring etc, make thing V confusing.

PS if its the Timing control valve does anyone know where to purchase one at reasonable price thanks

managed to get my ph down in underneath and take a pic. of inj. pump
IP Zexel 10406-2007 [under licience to Bosch VE4/11E2959RNP6 ]

Its an electronic VE pump not a VP44.

Will it free rev to redline?

It sounds like you might be on the right track. Are you sure those codes were right?

I don't know anything about a Terrano but for a Patrol - if your maximum boost was 11 psi - that would be low. When you replaced the turbo did you set up the actuator (on a ZD30 it's a vacuum control) to any sort of specifications?

THANKS AGAIN FOR REPLYS,,MUCH APPRECIATED

first shifted auto trans from Drive to second so it would peack revs without changing,,,,,, flatened it and eventually it peeked just on red line 4600
Stoped put in neutral ,flatened it and it quickly went to 5k,, lifted my foot as reflex seeing it hit red line,, i recon if I had kept my foot down it would have hit 6k
?????????
A friend needed an old trailer moved,, Good Test,, Took off in first [Auto ] ,It got to about 2k ,,,, and thats where we stayed, flat,,, lucky he only needed it shifted around his property.If I was on beach sand I doudt if it would have spun the wheels.
11 psi boost, using twice as much fuel as it should and NO smoke.

Turbo boost seems to rise fairly smoothly as revs rise,so if its not set properly set its only at the upper limits its going to "dump" when it should not, I havnt played around with that actuator setting. I prob will but that seems sort of "fine" tuning at this stage.

OK last test was early morning done after 2 or 3 ks warm up. Today [hot day, and after 10 or more ks ] did same hold in 2nd and plant it.
Revs slowly rose to max at 4,200 boost rising at the same rate then as i continued to hold flat the boost started to fall down to about 2psi then revs dropped back to around 3,000 and boost began to rise a bit and revs went back to 4,000 then boost dropped and so did revs.... the cycle kept repeating.
In nuetral and flat it went just up to red line 4,600, when i got home the engine was overheating.
Now im wondering if its a blocked exhaust.

[Dagwill]

Just disconnected exhaust before 1st silencer, went for a drive no change.
