Turbo M-Edition
I have a 1.8 with a T3 60trim turbo (details below the video). Everything has been running really reliably for the last few months and even got it re-tuned last week as a precaution but the shop said the tune that was on the car was 99% perfect and they just needed to barely tweek something little to make it 100%. Unfortunately yesterday I was coming home and did a 1st gear rolling pull, shifted into second with a loud backfire and now my engine is ticking like no tomorrow! Sounds louder than the lifter tick, which was fixed by changing my oil and its directly correlated with the rpm. It doesn't get louder as i accelerate but gets more rapid.
Any ideas on what it is? how to fix it? should I just build the engine while I'm in there for more power? If so what parts should I be using?
Any help would be HUGELY appreciated as I'm fairly new to the turbo miata/built engine game. Sorry for some Newb questions thrown in there.
Hopefully you guys can see the video

Like I said I am a complete newbie when it comes to tuning/building engines I mostly focus my efforts on aesthetic mods and leave the engine tuning to "professionals" but apparently I've left them to "professionals" that don't know ****. I was wondering why the turbo set up was only making 224whp at 18psi seemed like it should have been making more. SO any ideas on what it is exactly? Rod knock, lifter tick, chipped piston, Spun rod bearing? Honestly I have no idea. Luckily I have money in savings for just such an occasion but i'd rather re-build this engine for strength then buy a new engine and build it (save's my $900 for the new engine). Any ideas?

I purchased the car like this from a gentleman in Cali who had tracked the car for the last 10 years then took it to both drift office as well as carb conn who are both know for working on AEM stand alones as well as a few turbo miata builds, then took it down to CNC autosports to have them check up on it too. If I were to build the car from the ground up obviously I would have done a lot more research and learned to tune the car myself but since I purchased it from a guy who seemed to know what he was doing, then took it to three shops who all seemed to know what they were doing I would ASSUME it would be good to go and wasn't going to push anymore power out of it thus no reason to learn all the tuning. Plus the car ran flawlessly the last 4 months so I didn't think that I needed to do anything mechanically to it so started playing around with the cosmetics. And no it's definitely not "hella flush/stanced" I use to drive this thing like a bat outta hell, was going to take it auto-xing before this happened :.(
