sorry, was out all day and didnt get your message til late.
remove your intake manifold. remove he line from the t fitting, which will make it possible to remove the t fitting. it has to go into the other block int he same orientation cause the t fitting has different style threads i think. dont take the pressure sender off, just swap the take the whole sender/t to your p5. its right in the middle of the backside of the block so pretty obvious.
the coolant feed comes from right above the oil filter location.. you can pull the oil cooler stud from your msp, or just source a barbed/banjo fitting. i think the bolt that plugs the block is 17mm but if you have a tap and die set, just figure out what it is.
i didn't transfer the oil cooler cause i couldn't get the long stud out. so i just jumped the barb on the stock msp coolant feed back into the heater hose that it normally goes to without a load. PROB not idea.. so if you can just remove the stock hard line with new fittings and a soft line around the block, prob best. just take pics of how the msp is and copy it when assembling the p5, pretty easy.
dont disassemble the hardlines from the turbo though.. those are kind of a pita to reassemble later. getting the coolant banjos tight enough and having the lines facing the right way. but that might have just been a side effect of clocking my turbo downward.
