This is the world's first fully forged and balanced 6G75 engine.

It runs 12 psi boost for now.

The con rods are 35 grams lighter than the stock rods.
The piston is 5 grams lighter or almost identical in weight to the stock pistons, overall the rotating mass is slightly lighter.

The engine is noisier than stock when absolutely cold.

Forged pistons need different clearances, they tend to be a little noisier till they warm up and expand.

yep...takes about the same amount of time as it atkes for the car to switch from petrol to LPG.

Sounds like a bad bearing till shw warms up, as a precaution I always take it easy when cold anyway out of respect for technology and my wallet....LOL
