Hello all. I'm in the middle of replacing a k04 with a z54. Have you had issues with oil leaks due to the drain not being large enough? Just want to know what size works efficiently.
Also, who else has upgraded to a z54 and what has the experience/ difference been like? Do you enjoy the HP gain? Was it worth? What was your dyno hp numbers and/or track times?
Zzp says the opel injectors are enough for the turbo. They also don't recommend a BOV and said that the flutter shouldn't be an issue.
