Hi there!

We are building a new vq35 engine for street use, maybe driven somewhat hard sometimes. We where fitting the main bearings and did a measurement with plastigauge to know the clearance(will attach some pics). We found out that the clearance is on the tight end of the oem spec. Whereas the range is from 0.0014 to 0.0018 we are at 0.0014(please see attached pictures). Do any of you see any problem with this tight clearance?

Thanks in advance!

Kind regards,

Vincent
