Questions for my LQ9 N20 build. I posted this in the Nitrous section but thought afterwards I might have better luck here. So I have a freshly rebuilt LQ9 shortblock that im looking to spray. This will be a budget build to keep me occupied while im saving up for a forged F/I motor. Also before it is brought up let it be known my tune will be done by Dallas Performance so it will be top notch. So no need for "its all in the tune" post.
Im curious what people have seen these shortblocks handle reliably. I know with heads, cam and intake I should be somewhere in the 450 range N/A hopefully a little more. What room does that leave me for a shot? 150, 200, 250??
Im looking at Texas Speeds PRC heads and cant decide between the stage 2.5 243s or 5.3s. Any thoughts on which would be better with stock LQ9 bottom end, custom grind cam and LS6 intake for an N2O motor?
Also one last question. What are basic improvements to make to the stock bottom end to handle a little more? I dont mean forged rotating assembally, but are ARP rod bolts a good idea with spray? I know they are a given with F/I builds. Anything else?
