So i just ran a dry compression test.. I'm a noob to Forced induction so i will need some help with this..

These are my results from the dry compression test ( Didn't have any 10W-30 oil for wet test will retry this week )

96 miata base with 252k (Not sure if original engine )

1 = 175
2 = 170
3 = 170
4 = 150 / 165 = First test / Second test ( Test this one twice from the first low result also cranked more on the second

Worried about that 4th cylinder.. car runs great so far.. I've been beating on it pretty consistently low idle.

How is this looking for a turbo?

 

Boost the nuts off of it. It will be fine.

 

/\ What he said.

 

This is why I didn't compression test my motor before putting the turbo on. I knew I wasn't going to swap/rebuild it anyway, so I figured I was better off not knowing.
