Discussion and questions related to the course Practical Engine Building
good day .. wanted a little insight on rod and main oil clearance on a forged ej25
I will be running an HX35 turbo with all the supporting parts.. i am aiming for about 400WHP
currently, I am aiming for the main oil clearance of 0.0015" and a rod oil clearance of 0.002"
does this seem reasonable or should I tighten the clearances ..
thank you for the help
These clearances are pretty well in line with where I would set them for your application. If anything your mains are possibly a touch looser than they need to be but not to the point that I'd make an adjustment.
thank you for the quick reply andre..
when you say a touch looser.. what would be your recommended main oil clearance and rod clearance
i do need to mention that this a daily driver and weekend track car for time attack/ Gymkhana circuits ..
