Having some difficulties. Now as some of you no i was installing a new turbo well second hand unit now after install everything up the damm thing just wont boost. ive checked all pipes etc and it just wont boost past 0 so i checked the external wastegate took spring out it was okay then with it off i revved it the part inside wastegate when revved with no pressure on it opened up (to sound like a tractor) lol so i put my finger over it and went to rev it nothing happened it would push against my finger. unsure if its meant to do that, next tried disconnect the pipe from the boost controller to the wastegate, blocked it off and still no change, i also took all piping of the wastegate that feeds to turbo and it didnt work also. on this turbo the only place i could see to run the ext wastegate pipe to the external wastgate was on the plastic pipe that bolts onto the turbo, rather having cast tube running down for intercooler this has a bolted on part. i just cant think of anything else thanks for taking time to read this chris
