Pistons 1400 Overbore (PL140)

Pistons 1400cc Overbore Kit
1400cc KIT FOR 1300 ENGINES
• MUCH IMPROVED MID-RANGE TORQUE
• BORE INCREASED FROM 74 mm TO 77 mm
• DISPLACEMENT INCREASED FROM 1290cc TO 1397cc.

Our forged aluminum-alloy pistons are an update of the highly acclaimed “1400 Kit” which was popular when Giuliettas were new. The 8.3% increase in displacement greatly improves midrange torque. This will give your engine a flatter, broader torque curve with much greater flexibility. Compression ratio on a Normale is 9.5:1, and on a Veloce it is 10.0:1. No machining of the block is required. Pistons, piston pins and clips, and Hastings Piston Rings are included. The 1400 pistons will fit either 750, 101, or 105 1300 engines. Have your old liners bored to match. No discounts apply to pistons. Our 1400 Kit generates more positive feedback than any other part we sell! A 1600 head gasket is recommended.

Installation Note: Head must be chamfered slightly.
Always check piston-to-valve clearance when fitting new pistons.
