Terrified.
I do believe there is a link to rat's nest removal in the sticky at the top of the 1st gen section.
And yes there are a lot of differences, however the oil cooler - well I say upgrade to a front mount intercooler. Search to find out how to do that. The beehive oil cooler sucks.
Other than that everything should swap over.

Part of the reason to change to the FMOC is to lower underhood temps, so leaving it there eliminates this as well as as Trochoid says, too cold is bad, if oil is cold it remains thick and does its job less efficiently causing wear and power loss from friction.
Do not reuse the old O rings, check the heater hose beneath the beehive, they often fail from oil leaking onto the hose and can quickly cause a blown engine from rapid heat increase.

you are going to have to check the fb rats nest removal to get the exact hose sizes, but this thread contains a drawing that simplifies the hose routing down into a very easy to understand drawing
