All Japanese import cars run rich mate, my 33 GTS always has a strong smell of unburnt petrol becasue it is tuned for the higher RON japanese fuel; we have a lower octane fuel here so it runs rich.

if its something that concerns you a lot, you can buy a programmable ECU and lean out the mixture a bit. should improve efficiency.

no, that shouldnt be the case. A simple test to see if you have a fuel leak is when u take off ur fuel filler cap near empty you should get a PHSSST noise... I dont get it in mine and I get a fuel smell coming from the fuel cap. Possible breather hoses have perished I just havnt had time to take all the shit off and find out how to get to it. Anyone know an easy way??

    • If there's enough meat in the housing where you want to put the M12 adapter, then do it, but be aware that if/when you f**k that up you'll probably be repairing it before doing anything else. I'd just drill it out and tap ina 1/4" thread. No need for rocket surgery when the next most obvious thing will do. You could throw a 1/4 x 1/8 bush in there and use the same fitting you intended to use.
    • Is the only issue that the oil catch can is getting filled on hard runs? I'd be thinking more about oil control issues rather then the head lifting, especially as you aren't seeing spiking in the coolant pressure.  Do you need restrictors in the head, or better drains from the head? Does the sump need venting to the catch can?
    • Tried to make 1/8npt threads into compressor house of the turbo for my EBC. Threads got fu#ked and ended up with and elongated hole, so I do have good amount and nice threads 90% of the hole but 10% I only had 1-2threads there and rest of it is flush on that side of the hole.. So my idea is to do M12 x 1.25 to AN4 with braided lines instead of 1/8npt to 4mm vacuum silicone hose.  and hopefully get a better thread. M12 is quite big and AN4 is a little bit bigger than 4mm (4.9mm inner diameter braided PTFE hose). but this should work. Thoughts? Otherwise I will weld and adapter onto the turbo.   
    • Looks great, I hope everything is working well after all that time!
