Key Features & Benefits – Wössner Fast Road Comp forged piston kit for Nissan 350Z 3.5 V6 24V VQ35DE, 96.00 mm
The Wössner Fast Road Comp forged piston kit for Nissan 350Z 3.5 V6 24V VQ35DE, 96.00 mm is made for 2003–2009 Nissan 350Z 3.5 V6 24V VQ35DE applications with a 96.00 mm bore size and +0.50 mm oversize. The catalog lists 3535 cc displacement for this version.
This size uses a 29.60 mm compression height, 10.0:1 compression ratio, and 22 mm pin diameter together with WP046-SP wrist pin, 960XPY ring set, and CW22 clips. Within the Fast Road Comp range, this is the intermediate oversize step below the 96.50 mm version.
When is this useful?
This version is useful when the block is already moving away from the factory bore but does not need the +1.00 mm oversize option. The 96.00 mm bore size, 960XPY ring set, and 22 mm pin spec give a clear checkpoint set for assembly planning.

Selection & installation tips
- Bore size: Check that the block is machined for the 96.00 mm version and not for the 96.50 mm option.
- Oversize: Compare the +0.50 mm oversize with the current machining state of the block and the target bore plan.
- Ring set: Verify that the 960XPY ring set matches the selected bore size.
- Pin side: Compare the 22 mm pin diameter, WP046-SP wrist pin, and CW22 clips with the small-end setup of the connecting rod.
- Geometry: Review the 29.60 mm compression height against the assembly plan built around 81.4 mm stroke and 144 mm rod length.
Before assembly, verify the bore size, oversize, ring and pin identifiers, and compression height, then compare them with the listed details.
