X51 oil pan to prevent oil starvation issues?

[bjarne996]

I have a 1998 996C2 3,4 with the following chassis upgrades:

-PSS10 coilovers

-GT3 sways

I use GT3 street wheel alignments.

To avoid the added G forces possible with these upgrades leading to oil starvation I have ordered an x51 oil pan from Suncoast.

However, I've just read that LNengineering claims that the x51 oil pan does not improve the situation unless the additional x51 oil pump and suction pipes are also used.

Is this really so, or is LNenginnering making a case for their own deep sump kit?

Have anybody installed the addtional X51 parts:

Pump: 996.107.980.00

Suction Pipe: 99610798402

?

Thanks,

Bjarne

Yes the statement on the X51 sump kit is correct.

To add the additional pump requires removing the cylinder head and doing some machining - or buying a pre-machined cylinder head for X51. So this is much more than add-on parts.

Does the X51 kit work better than the LNegineering kit?

Hard to say - the LNengineering provided extra sump capacity that one hope would make up for the slow return from the cylinder head. The factory X51 kit uses a pump to the return the oil and does not increase capacity.

I guess machining the cyl head a much bigger job than I am prepared to take on.

If I understand you correct adding the x51 oil pan on its own will not reduce oil starvation issues on my 3,4?

Should I get the LN enginnering deep sump kit instead?

Both will help with the problem.

The best solution would be to find a used GT3 to race.

:oops: Do you mean that the x51 oil pan on its own will improve the situation, but not cure it competely?

(Sorry if I go on here, just want to make sure I understand you correctly)

X51 pan won't solve the problem by itself. The problem is oil returning from the head and oil going to the head(s) under corning force.

The pump will send it back on an ongoing basis. The LNengineering deep sump prevents some oil from going to head.
