Terrible knock on newly swapped SR

WakingDream's SR rebuild / swap

Hey guys. Bought a redtop from JDM Engine Zone 2 days before thanksgiving. FINALLY got it started. At first i had a problem with it idling at 3k rpms but i was told to let it sit for around 10 seconds and the computer should "relearn" its correct idle which did infact work. BUT while i was fixing the idle whenever i would shut the car off it would make a bad knocking sound. The car has only been started now a handful of times since the swap and now the motor when idling sounds TERRIBLE. Is it possible my CAS isnt adjusted correctly and making the motor knock? I am going to run a compression test in 2 days to see if something is blown on the bottom end. ANY info or insight would be a life saver as the car is my daily driver and the motor blew up so i replaced it with the sr which ive been working on for over a month now. Ive dropped over $3k on motor and slight mods and its looking like the motor is nothing more than a paperweight.

I read somewhere that the AEM one isnt very accurate, maybe google some reviews on it. I also got that flywheel!

If you want basic, I would go with the Blitz Dual SBC Spec-S. It's designed for applications where you are going with less than 1bar. The Spec R is designed for higher boost apps. It's pretty simple and has 4 boost settings, based off of % over stock. Then there's a "scramble boost" setting for quick jaunts. All you have to do is set the gain setting for your particular car (20 for SR, IIRC), adjust the tabs on the back, and you are good to go.

FINALLY got my motor back today. Looks very nice. Have a question for you guys though. I replaced my manifold with a header and while doing so, i saw that a spot weld holding my wastegate actuator on was broken :(. Should i get a stock one or hks one? i do have stock bottom internals and top internals but ill probably upgrade the top and boost more than 1 bar which i believe the hks actuator maxs out at. Can i run the hks actuator at like 12 psi then once i upgrade add a boost controller to hit maybe around 16-18?

i guess 550cc injectors would be enough for like a mild cam and new turbo? i dont have the money atm for the injectors or id definitely take you up on that ;) also once putting all that on really how hard is it to tune the air / fuel mix with correct equipment? ive never adjusted air and fuel before.... it sounds like jim wolf tech is pretty much the way to go
