i believe 2point6 is now running a 2.4L. he had a 2.6 and had too many problems. he runs low 13's and he may have hit 12's recently. it could be costly. you would need new pistons at least. and while youre at it you might as well just build the whole block. to have it sleeved, new rods, new high compression pistons, bearings, blueprinted-balanced, bored, machined. it would run about $2500-3000. 2point6 made i think 225hp and just guessing but i think it was 190ft/lbs of torque and he runs low 13's in a 4th gen with full interior
