nobody has got ideas huh

 

I would go with a 75 or 100 wet shot. You won't have a problem as long as your fuel pump is in good shape. I like the formula of your stock Hp divided by 2, it will give you a rough estimate of a safe shot.

 

Depends on the miles/condition of the car.

I sprayed a NX 150 on my car when it was at 135k before the rebuild.. A friend is spraying his 92Z @ 165k with a 150 NX..


Depends how you use it, and how hard the miles were on the car...
