GTM 1380 Big Bore Kit - Carrillo Rods

GTM Forged 1380cc Big Bore Kit

Take your 1200-8V (1151cc) to 1380cc with CNC weight matched forged pistons and Carrillo chromoly steel rods. Pricing is for one pair (2 each), as shown. Pistons come with all rings and wrist pins/clips - rods do not include crank bearings. This kit DOES NOT require crank rebalancing, but cylinder services and related are on you.

Second Option is GTM-BB-Kit-Compl(ete) which includes CNC Pistons and Carrillo Rods above, along with two (2) new OEM cylinders with all gaskets, and additional parts to make this work on most all 2009-2017 1200-8V engines.

Our GTM FULL Fuel Kit HERE is MANDATORY - With this, it will run beautifully on on pump gas, stock compression. Dyno graph for this kit used on a '13 Griso-8V HERE.

This was developed for our custom GTM builds. Complete motor build services available with GTM performance cams available to transform 1200-8V motors into incredibly powerful engines. Contact us to order and timelines.
