2008 Apex MTX (Need Advice)

Dok,

Mine was doing about the same thing as yours is. I broke a piston land when on nitrous. Get your hands on a compression tester and test each cylinder. You will find at least one cylinder is bad. It could be a valve problem but not likely. Did anyone have the cylinder head off? A bad valve could give you the same symptoms. Man, If I was running a turbo or S/C and had to tear it down, I'd probably install some lower comp pistons. Might as well since you'll have it all apart.

Anyone know what lower compression pistons and high performance connecting rods cost? I might tear mine down this summer and completely rebuild...make ready for a new turbo.

Retail on the SK1334 (Wiseco 10:1 piston kit) is a little over $500. Carillo rods are about $1200.

Just found out that I have one bad cylinder and a bunch of bad rings! I am going to go with the lower comp pistons and the good rods as my dealer recommended them too. Looks like I'm riding the cat for the rest of the season! Thanks for your advice guys!!!!!
