Helpppp

I cracked number 3 and 4 Pistons. I need to know if the LDK can handle my mods with out the same problem or if I just need to build it money is somewhat a concern I don't feel like spending more then 6000 including labor. My mods at turboxs charge piping, tread stone intercooler, 3 in catless down pipe, intake mod with upgraded tube, and a 1.0 lnf pcm from zzp. What would be the best route for a long lasting solution without giving up power. all opinions are welcome. Thanks

Figure out why you cracked the pistons. Which I would guess is related to some engine knock occurring at high load

Technically a stock lnf can handle your mild mod list without a sweat assuming the tune is good and other peripheral componants are sound.... Including driver mod. A ldk is stronger, and is a good option, however is not bullet proof. I'd be tempted to say something else other than your mods caused the engine failure imo.

Ldk pistons don't seem to be stronger from what iv read. Ur motor should have handled the power and mods without any issues at all. There are a few of us that are on Zfr with 400 plus whp and engine taking it fine. Something in ur setup caused knock or something like ecaulk said. What kinda gas were u using?

LDK pistons are exactly the same as LNF. So of course they're not stronger. That wasn't really the point I was trying to get across though.. lol
