im looking to do something different, & want to put an m90 on the ln2 i have in the garage, & im looking to push 220-250hp. im not a fan of turbos because everybody turbos, & ive always loved the m90 & the results it provides (up to 300 horse that is)-my question is this.

if i get h beam rods, will the stock pistons & valvetrain assembly of a 94 ln2 be able to stand this kind of boost if i upgrade the rods, get a header, & do other exhaust/tuning mods (im getting a moates programmer from moates.com)-but can the other engine components handle this much boost?

i think you have a lot bigger challenges than pistons charging an ln2

nothing stock in an ln2 will be able to handle any kind of boost above 6 psi without doing any kind of damage,
