that black pipe didn't go to a map sensor, it went to the boost control solenoid. the map sensor is built into your ignition module, which is piped upto your manifold.
you'll either need to drill and tap the compressor cover so you can screw a brass tail in to push the hose onto, or somehow 'T' it into the pipe comming from the turbo. You could drill/tap the intercooler and pipe it into there if you wanted. anwhere between the turbo outlet and the throttle will work fine. You cannot connect it to the manifold though.
by the way, thats a T28 you have on the left, not a T25
What other engines use this fitment of turbo, guys? Is there alot knocking around?
cheers scoff my new unit is off a skyline one of the two it had
ah right, some of those had T28's. they have ceramic turbine's don't they ? If yours has, you'll need to be carefull with boost, or so I've heard.Originally Posted by reevio
Yeah ceramic exhaust wheels. very very fragile, i chipped one removing a turbo, luckily the shaft was toast anyway otherwise it'd be a new v expensive ceramic wheel, not even sure if there available.
yeah, thats it. reevio, you can tell if you have a ceramic turbine by checking for a nut on the exhaust end of the shaft. non-ceramic turbo's don't have a nut, the wheel is part of the shaft.
mine hasnt got a nut its one complete turbine and is metal
