LQ4 forged pistons, stock rods?
Hey guys, im new here and would like some opinions on my idea
Im in the process of doing a budget turbo LQ4 build for my swap in my 00 Firebird. I am looking for 500-600hp daily and 700ish if i turn it up occasionally. We got the motor all torn apart and im not sure all what i want/need to replace. I was recently thinking of getting the forged dished diamond pistons and use stock rods with arp rod bolts. With the 317s, compression should be about 8.9 and i was planning on running head studs.
So im wondering how much boost the stock rods can generally take as long as i keep the rpm under 6k. I bet 20# would be pushing it, right? Ive seen a lot of stock motors on here take 12-15#, so i would think it would do alright with 20# with the rod bolts and lower compression forged pistons.
I also need to convert everything to put it into a v6 firebird, but thats a whole other topic...

Rods dont cost as much as pistons, so if your doing pistons maybe go ahead and do rods too? Then you can go berserk and do almost anything you want boost wise! Sorry, Im not sure how strong the stock rods are, but I'd bet you could run 700whp through them unless you just got unlucky, my LQ4 car only dynoed 520whp.

I have a feeling that if you go through all the work of rebuilding the engine and dont spend a few hundred extra to get better rods you are going to kick yourself later when you want to start cranking up the boost. I say get forged rods, it will be worth the peace of mind and added reliability.
