I belive that the BSI & key remotes with the immobiliser chips should be changed along with the ECU unless you virginise the ECU first as they are a matched set.

Swap everything over engine wiring loom for engine ecu and code box under dash with key and it should be easy enough gearbox same as are shafts exhaust downpipe different depending on turbo best use 8 valve one to be sure its right.

Some pipework differences for rad but only minor.

Blocks are actually the same casting only crank pistons and heads differ.

Went to start my project today and discovered the rhw 16v wasn't a 16v after all but an 8v rhx engine which was turning over but not starting so I put the diagnostic on and it had these stored codes-
P0380
P1112
P0235
P0245
P1517
P0340
P0191

I then cleared these codes and it came up with just p1107 then upon attempting to start up came these codes
P0380
P1107
P1108


Anyone any ideas I'm thinking maybe faulty loom and heater plug relay??

forget glowplug fault and indeed forget reading faults you need to read live data for fuel pressure cranking speed and cam and crank sync these are all that's needed anything else is extra and can be fixed once it runs

31 bar way too low needs 120 bar to start then it rises to 298 at idle

96 rpm also too low needs 250 rpm try towing it see if it goes if not I would then do a leakback test on injectors.

Is the tank pump priming ok ?

Taxi starts very easy on jump and drives perfect for a couple of mins then goes to limp mode and drives for about 5 mins then cut out started again on tow straight away and drove for about 2 mins jumped immediately again and reversed into drive and let it tick over for about 40 mins then turned of with key but again won't start with key. I noted down the live data at tick over and also with about 3000 revs while in the driveway
