Even more if you say you had compression issues. But overall here each car is different. Something I learned from Ash the other day and I kinda remember reading a while back was that Nissan used different parts on the motors during the Z32 years of production. I asked why my cars rwtq with far less mods was the same as the one they Dyno tuned that was more like Stg VIIII++++. He mention'd Nissan using slightly bigger cams in some years or motors which more than makes sense since I took the car in twice, two different times ran two different levels of boost on the very same parts with in a week of each other and got just about the same results.
