I had the same symptims once, and it turned out to be a coil pack.

One of the little springs between the coil an the spark plug was missing and the coil pack oxidized in the shaft.

I took out the plug and cleaned it with WD40, replaced little spring and all was good!

sweet so it may be a boost leak just out of curiosety were was ur leak and another Q theres to metal lines comming offthe ceramic intake pipe windering were they go do they go into the charcoal canister or were else lol soz im new to these rb20s
They probably go to a charcoal canister. And they probably are what is causing your boost leak (if they're not connected to anything)!

    • Aren't these run off of high voltage in OEM applications? Like 200+V. Or at least 48V in mild hybrids. At ~18,000 BTU ballpark nominal capacity the power draw is at what, 2.2 kW? ~185A is a pretty crazy amount of amps. At 200V it's only 11A. The 70A nominal kits with up to 100A peak draw I see for stuff like classic Porsches have pretty substantial compromises like shutting off at idle and not actually managing to keep the interior cool in hot conditions because they can only output like 6000 BTU. IMO if I had to pick what high amp draw component to retrofit to these cars I would start with the engine fan, not the AC compressor. You need an ~850-1000W brushless fan, something like this: I would love to see the data but I would bet that whatever you save by running the AC compressor in a more efficient regime with an electric motor you're probably losing to conversion losses anyways. It's not really like a clutch fan where you're losing power all the time even when it's nominally disengaged and it gets worse as it engages because the envelope tracking isn't that precise.

    • Bit of a long shot but if anyone has 4 of these laying around in new or near new condition. I will happily buy them off you.     https://skylinespares.com.au/product/stabilizer-door-glass-inner-new-8032404u03/?srsltid=AfmBOop6L5EgUFaHPHiVXoAhv5k8aJYwc77nGmoApp-hY03OiOsNVaOv Thanks 
    • I'm wondering is the Toyota and Mazda "collaboration" could see that new Toyota ???G20 ??? turbo engine that they have been showing off recently into a future MX5, apparently it's good for 400hp out of the box That could easily, possibly, be much better than the last collaboration between Toyota and Subaru with the boxer engine in the twins
