Help!! Rb25 oil block drain holes
 

Hey guys I'm in the process of finishing my s1 rb25, if like to know if has personally blocked off the oil ports and which ones at that and size, and if you think it's needed.

Mods

S1 RB25
Rb26 itb intake manifold
Mahle 86.5mm pistons
Manley H-Beam Rods
Rear head drain kit
Extended crank collar
N1 oil pump pump (added billet gears)
baffled oil pan (coming soon)

Nobody has ever done this on here?

I don't think anyone knows what you're talking about.
