hey everyone im new to rx7s ive always owned mr2s but my 93 enfini isnt boosting properly.
i get to .5 bar and it completely bogs. im thinking it might be a bypass valve.. but im not sure. any ideas?

make sure all your piping clamped together and the cacuum lines are all hooked up properly

do you mean it drops boost? from .5 bar?

hey everyone,

my FD is acting up again! its getting to .5 bar and just bogs, but only when its colder (5-6oC) when its nice out its fine just boost. I really dont know what it is. im thinking it might be the bypass valve..
any ideas?

could be a vacuum leak

I recommend you look for a boost leak in the intake piping, bad check valve, or a loose vacuum hose.
