Howdy. Names Cody, I'm from Texarkana, anyway I drive an 86 Corolla GTS (ae86) so I feel I lil outta place but I need you guys help. I recently decided to turbo charge the poweless 4age so I would have that lil extra power when I need it. So I went to a local scrap yard and managed to pull a Turbo off of an 86 or 87 (cant remember which) GL-10 Wagon Turbo AWD. My question is, what PSI does the wastegate release at? or rather what PSI did those cars run bone stock? I can't find it anywhere online nor in you tech section. The turbo is in perfect condition, no bent fins no shaft play at all. I just need to know what kinda boost its making, cause I'm installing on stock internals and don't really wanna get over 7 PSI. One more question.. what size is this Turbo? Like whats the numbers/letters that represents the model? Sorry I'm not really all that turbo smart, I'm still learning. So I ask the subaru gods, can you help me out here?
