88 (turbo) thunderbird has low power Reply #19 – September 02, 2007, 01:23:13 AM take it off, grind the crack a little deeper then weld it. Cast iron needs cast iron rods.if it aint broke, dont fix it, the motor should stay put if it runs fine.Your best advice so far was given to you already,,,,, read up and learn about this car and how it works. You just stumbled into a gold mine of a web site, we all love these cars.When someone replies to you about your turbo coupe,, i can assure you ALL of them know their stuff. Quote Selected

(was thinking brake booster, seen them make loss of boost ) outside, intake seals, turbo charge piping, yatta yatta Quote Selected

great Reply #23 – September 03, 2007, 10:02:27 PM I don't have a shop, so I think I will just grab a "new" manifold off of something @ pull a part. The "hissing" noise, although gone, seems to still blow through the vets inside the car when the turbo is boosting...How long will/should manifold replacement take? I'm pretty experienced with fords (I have a '67 302 mustang) as is my g/fs father, who will be helping me; he owns a bronco. But I have to admit this is my first non carbed car, is there anything I should know? Quote Selected
88 (turbo) thunderbird has low power Reply #24 – September 03, 2007, 11:34:27 PM Look under your dash, or pull the cluster. The rubber hose that goes to your boost gauge probably came off. If I remember it right, the hose has a red stripe on it. Quote Selected
