what year vitara do i need to order pistons from grand vitara or just vitara is there s diffrance 2.0ltr or 1.6ltr OR does it matter ?? mark 2 vitaras or mark 3 can anyone help me plz i want to order these but dont want to order the wrong ones

 

Noob here & have found this info very useful. I'm currenly rebuilding my D15b2 block/Z6 head for a cheap/budget boost mini-me but have concerns with the compression #'s.

I'll be running stock rods with Vitara pistons looking for only 180-200 whp on a good tune. Hate to bring up the old shiet but What would my compression be with this set-up?

I used the zealworks compression calculator but don't know if I should be reading the static comp/ratio or effective/comp ratio??

I'm guessing I'll be around 7.2/5:1

If I chose to deck my block, what is the maximum I can deck a D-block?

I'm also guessing that I'll need to deck approximately .125" to bump up my compression to 8.5:1. Does this sound right and should it be done

Purchasing low-cost rods isn't really an option.

Thx in advance for any solid advice.
