i have a tial 38mm wastegate.. and i need help hooking up lines to it, been doing research and everyones is different. theres two ports on it. one on the side one on top. i have a bleeder style mbc if that helps. but i need help pics if possible. some people have just the side used and left the top open. some have both used?? thats why im confused. someone shed light on this subject for me plz.

from pressure line to boost controller, from boost controller to lower side port. top port is just a vent


running rich? turn the boost up

Not hard. The top stays open to atmosphere. The side hooks up to the compressor housing of your turbo. (Or as close as possible in the charge pipe)

You only use both if you have an electronic boost controller and/or CO2 setup.

ok thanks thats the answer i was looking for.
