  
TODA Racing offers high compression forged pistons for the Honda B series DOHC VTEC engines. The kit comes complete with forged pistons, rings, clips, and heavy duty wrist pins. Offers great gains when combined with Spec B and Spec C camshafts. TODA pistons maintain the Honda factory piston to wall clearance and allow for quiet and reliable operation.
The basic form of the piston is an elliptical barrel. This forms the basis from which each part is subjected to high loads and measured for thermal expansion to accuracy of 1/1000(mm). The top edge of the piston uses a castellation design to reduce sticking, improve lubrication and sealing. The design also acts as a scuff-band to reduce run in time.
TODA piston also feature improved oil drainage with redesigned oil channels. Improved oil drainage reduces piston weight during engine operations which is ideal for high rpm use.
TODA pistons are produced in house using a 3000 ton press and come fully balanced within 0.25 grams of each other.
