    Those are the stock rods and bolts in the pics you posted. If somebody sold those to you as Eagle rods then you got ripped off. From the pics it looks like you just washed the stock rods and re-used them? Also I must have read over it before but you said that 625whp is reachable? It's definitely not reachable being N/A. You could get there being turbo but you'll have to strip that engine to the bare necessities of running with a huge turbo and tuning that it not possible on the stock ecu, even if you think it's "reprogrammed". I also hope you didn't pay much for the "stage 2 head". It's just a stock head that's been cleaned and resurfaced. Those cams may be stage 2 but that doesn't make the whole head stage 2.

    I'm not trying to call you out on anything or piss you off but based on everything I'm seeing here I thought you need some enlightenment.

      Well somebody got really defensive. Only trying to help, or bring you to realization.

      well, look at it this way when you try to "enlighten" all your doing is just being an asshole with useless knowledge, or with stuff that is already known. you were scoping my build pic's for some reason, but like I said I know what I bought and Installed and I don't need someone else's opinion/criticism unless I specifically ask for it. I know more about a 420a and 4g63t engine, then you know your way around a toothbrush

    Why did you get 1000cc injectors? That's way too much for a N/A 420a. You could've made passed with 500cc with that mods list.

    Also fyi, there is no such thing as ECMLink for the 420a. Megasquirt is really the only option.
      1000cc injectors is what I went with, this is why @ 90% cycle on 50 psi Naturally Aspirated
      Horsepower supported @ crankshaft: 735
      Horsepower supported @ wheels: 625

      with proper connecting rods, pistons, and tuning Its reachable

      Ecmlink is available to the 420a if you option for socketing on 2G dsm which i did but I had to send my current ECU in but that was awhile ago I don't know if its still offered its easier to just buy the ECU already to go
