hey ,guys i was wondering if u could help me w my baby rx7 1993 it's stock, has 82000 miles but one of the twins it not boosting. 1. it's leaking oil 2. it's doing like a fuel cut so what do u guys suggest? I was thinkng of going single but I don't know what size. i don't want to blow my engine. If u could please help me, i would definetely appreciate it. Thank.
Laz.

p.s. Also, I'm looking for a right headlight cover.

Someone has an entire write up on how the twins work and diagnosing them. Do a search for sequential turbo or something like that and you might be able to find it.
