After a long time from the car i decided to start putting it back together and complete the singel turbo conversion on my r33 gtr, with a 6boost and a EFR 8374. Well i got stuck on the DIY downpipe when i couldn't remember if the engine should be in "level" when it sits on the engine mounts and with the gearbox installed. I guess it should be but I'm not sure so that is my question.
With the engine in the car without the gearbox, can i use a "bubble level" on the intake to see that its in level or is there a better place to use rather than the intake? Or should it be tipping "front / back"?
As it sits now i have the engine on the engine mounts and woodblocks under the rear of the sump to keep it in level.
The concern is when i put the gearbox back on and throw it back in again and the engine was supposed to be leveled but wasn't that it ends with the downpipe no longer fitting.... trying to avoid that.
