Freelander engine change

[chrisg3103]

i have a bit of a conundrum, see what the collective thinks.
Bought a 64 plate non runner and from what I understood engines were the same, just ancillaries are different, bought an earlier engine and there are some physical differences.
Most important one being the later blocks have a water cooled turbo, and have a different block casting to accommodate the feed pipe tapping.

Later block with pipe near core plug

Earlier block with no pipe
Also the later engines have a different crankshaft (alter stroke for compression ratio), flywheel and clutch (handle more torque), and lower compression ratio.
Now, I have read somewhere else about someone tapping into a heater hose to get around the water feed, but not sure what running a higher compression ratio would do...
I'm looking for a later correct block but have this one sitting, and I'm wondering, In theory would higher compression ratio mean higher power
Just fit the later clutch design that was built to handle more torque.

an sheared flywheel bolts...

I can't help but excellent engine carnage

Probably a stupid question but wouldn't the fuel maps and other ECU magic be all wrong if you fit an engine with different compression ratios etc (unless your going to swap the ecu's etc too)?

That's the conundrum, how would fueling and performance be affected with an increase of 0.7/1 compression ratio

There are a fair few different head gasket thicknesses for these engines. Cant imagine BMW changed the stroke of an engine to lower compression because the bore size would have to increase to compensate, may have left a bit on the block deck.

Answering my own question from earlier. At the minimum it looks like you would need to remap it to account for the higher compression ratio.

• Ignition timing advancement:
  As the air-fuel mixture ignites quicker due to higher pressure, the spark needs to be timed earlier to occur at the optimal point in the combustion cycle.
  
  
• Fueling adjustments:
  Depending on the engine and application, increasing compression might necessitate slightly richer fuel delivery to prevent detonation, especially at higher loads.
  
  
• Load-specific tuning:
  Different engine load conditions might require unique adjustments to ignition timing and fuel delivery to optimize power and efficiency while mitigating detonation risk.

If it's a 64 plate it's a Freelander 2 with the Ford / PSA engine, not the BMW from the FL1.

Personally I would fit it and expect it to run just fine! As for the coolant take off, what about that handy core plug just above the later pipe connection? how about brazing a boss into the middle of a new core plug and modifying the coolant pipe to fit? I am assuming it is a diesel engine, but for a petrol the Lambda probe would take care of mixture adjustment and knock sensors would prevent pinking.

Generally diesels running bigger turbos/higher boost pressure will use lower compression ratios, which would also account for the turbo also being water cooled.

The big risk will be too much combustion pressure once the turbo gets wound up, which is likely to cause something major to fail.

 

[Bobupndown]

What happened to the old one to suffer such a catastrophic failure?

 

[jmp49]

Is the wastegate manually controlled by a spring inside the wastegate can on the turbo? if so, the pressure that's set at dictates the boost level coming out the turbo and on boost combustion pressures.
If so, could you just keep the original aircooled turbo on the earlier engine to avoid messing about with adjusting wastegates?

I opted to find the proper block, bit less risky...
Except the one that was sent was again the wrong engine seems they tried it on and sent a different engine to the one in the eBay add, but failed to notice the glaring error of it having an automatic flywheel instead of manual! Was the right block at least.
Couldn't argue that so got half my money back, then noticed water on a bore scope and ended up pulling the head, no real water damage thankfully.
That's when I found 3 snapped manifold studs and a burnt out glow plug that ended up snapping.
Also found all the rockers so badly worn they were pressing on the valve spring retainers, fun and games but will have a mostly rebuilt engine by the end of it
Also @8ob was quite correct, several head gaskets, I have a 3 hole gasket engine

To watch out for on a Freelander / Mondeo/ Peugeot 2.2 engine
Rocker on left is from the 2010 replacement engine, valve stem worn a hole in it and edges contacting on the spring retainer cap, rocker on right from original 2014 engine, a lot less wear but still there...
Good way to drop a valve!
