[rbs14kouki]

i need some advice from you guys !!! i have MAHLE 87mm piston for my rb26 and i would like to know what is the best Piston To Bore Clearance And Ring Gapping for my set-up .

i wont go over 550/600 hp for this built !!!

i saw some post about Piston To Bore Clearance And Ring Gapping in some other threads , but they were not for MAHLE .

thanks in advance

P-O

for a CP street engine mine are almost the same

piston-bore: 3 thou

top 16 thou

second 18 thou

oil rings more than 15 but no more than 20

i get a great seal with this combo if ran in correctly but leaves a little headroom if the engine see's more boost.

hey V-spec Tomei recommended piston to bore is 1.9-2.2thou!

Trini with that power level id use a little larger

Piston-bore 3.25thou

top 18 thou

second 20 thou

oil rings 16 thou

If you have read the other threads then you would know that every single time the recommended clearance is advised by the manufacturer, then you go 0.0005 - 0.0010 more.
