Block - Cleaned, Bored out to .20 (75.5mm Pistons) .0035 p2w(Piston to wall) for Vitara Pistons

What piston to wall clearances should i run with vitara pistons?

Usually it depends on your Power goals. The pistons expand when they get to operating temperature.
The more power you are aiming for the bigger the piston to wall clearance should be.

If you use standard bore Vitaras your pistons might be a bit on the loose side but it is not a bad thing if youre aiming for ove 400whp.

If youre using 75.5mm Vitaras and your power goals are between 250-350whp a good P2W clearance is between .003 and .0035.
For 350-400whp—> .0035 to .004
For 400whp or more—> .004 to .0045

Oil Pump – Run a stock D16Z6 oil pump it works the best even with turbo.

Oil Filter – Use the S2000 oil filter, and fill it 50% before screwing it on to the engine to make sure it is already primed.
