Okay so I wrote down everything I did when removing my 1990 Daytona ES 2.5 Turbo I head, with turbo and manifolds attached. I also wrote down what tools I used for the steps that required tools. So to any other newbies out there this should help you.


move car to location where coolant can drain

let coolant drain (dont need every drop out)
disconnect heater hose tube from bottom of water box and cap (crowsfoot 3/8" with long 3/8" extension and 3/8" wrench)

remove dipstick retaining nut and swing dipstick bracket off the stud (3/8" wrench, 1/2" socket, 3/8" short extension)

loosen bypass valve hose to airbox clamp (medium flathead)
disconnect bypass hose from airbox (use long thick flathead to push on hose from above)
remove nut from airbox mount stud (1/2" RATCHET WRENCH)
disconnect fresh air hose from airbox
loosen airbox to turbo input (oval) clamp (extra long skinny flathead, behind intake manifold elbow)
disconnect all remaining hoses from airbox

disconnect turbo oil feed line from block oil manifold and cap tube (1/2" wrench)
remove upper 2 ac compressor bracket bolts (15mm ratcheting wrench)
remove bolt from gnd strap and o2 sensor harness bracket from rear of intake manifold (1/2" ratcheting wrench)

jack passenger front side of car up high
from under the car, remove two bolts holding exhaust downpipe to swingvalve (3/8" impact wrench w/ 1/2" socket or 1/2" ratcheting wrench)
remove 2 bolts from turbo to block oil drain tube and break flange away from turbo if needed (1/4" socket wrench, 10mm socket, medium extension)
loosen clamp on turbo drain tube (w/flange) and pull turbo drain tube from hose (small flathead)
loosen turbo coolant line bracket to block bolt so that tube can be wiggled (15mm socket, 3/8" socket wrench, short 3/8" extension)
disconnect turbo coolant line from turbo and cap (5/8" wrench) (COOLANT WILL FLOW OUT OF TUBE, keep tube end high)
remove turbo to block bolt (on turbo side) (15mm ratcheting wrench)

a engine lift works well if your doing this solo.
Actually we found that on a hoist the head assembly always wants to drop towards the back from the weight of the turbo so the second time I layed the turbo into place first then installed the head/manifolds and attched the turbo after the head was on.
I was able to get to the turbo and the 2 bottom bolts from underneath and the 2 uppers from underhood.

You will still have to remove the head/manifolds/turbo as an assembly since you will probably not be able to break the turbo nuts loose on the car.
