Yes stock turbo and hks type bov like chinese copy or something.. but now everything works , the noise came because i didn't have gasket between CAS and the cover now the noise is gone, but i failed Emission test on idle.. Emissions IDLE HC - 140 CO % - 1,7 02 % - 6,1 CO2 % - 8,8 Lambda - empty space Emissions >2000rpm HC - 58 CO % - 0,2 O2 % - 1,4 CO2 % - 14,4 Lambda 1,03 any ideas?

and one more question, here's the picture before I had the cam cover on i have this one hose going into the same pipe that comes from MAF should it?

ok so , now engine warms up like it should and stays cool after thermostat change , now i have black smoke coming out of exhaust (didn't happen before t-stat change), and a strange noise from crank angle sensor or something it didn't have cover before and there was no noise, now i installed a cover and now it gives me strange noises.. any ideas? and i found out i have r32 ecu black smoke here : https://www.youtube.com/watch?v=Eur1jjpDnI4&feature=youtu.be strange noise here: https://www.youtube.com/watch?v=q6cmdujSLeo&feature=youtu.be

i'll continue in this post if I still get cold start/running rich problems

termostat was stuck open, i'll get a new one in few weeks ..

and i live in finland so it's very cold here.. should i get a winter thermostat one or regular one? how will it work when summer arrives ? will my engine run too hot then?

don't know if it's a nismo or a cold weather one. and it's a pain in the ass to change a thermostat..

ok, now both sensors are working and car doesn't run nearly as rich BUT the water temp gauge doesn't even go where it supposed to be (half way on the gauge) it goes like 35% up and stays there, even if car were running for like half an hour it stays too cool? Is that a problem? and when i squeeze the pipe on the left side which goes to the radiator, i hear a "leak" like noise from somewhere and if i squeeze long enough you can see air bubbles start coming from the coolant liquid container cause it's see through.. ps the pipe is warm not hot and is easily squeezable (very soft) feels like there is no pressure at all inside. should there be? there's no more "sailing" on idle.

if i remember right the resistance was about 1.6 ohm or something, from the 2pin ecu sensor, hoses are in pretty bad shape, i changed a couple ..when i squeeze the radiator hose on the left side of the engine (from radiator to engine) i hear kinda "leaking" sound from behind the engine , the radiator and radiator hoses stay "warm" not "hot" i can touch them with your hands and not get burnt at all, how do i check if my fpr is blown and how to check thermostat, should i remove it and take a look? soon i'll drive this piece of shiaaat off the cliff...

the second picture is for standard boost solenoid and i have manual boost controller so should i leave it ?

so, my r33 runs too rich, and when i connect computer to the r33(below the steering wheel) and run the error codes it says o2 sensor is fried (code 13) but i tried changing it (to original sensor from friends car) and it still runs the same and still gives error code and i get like 0.7-0.8 V max (program shows) and my water temp in the dashboard isn't working at all, it doesn't rise at all, so i tried to clean the water temp sensors (both the ones that goes to ecu and the one that goes to dashboard) still nothing the one that goes to ecu shows some Resistance (ohm) and changes as the temp goes down so i guess it at least is working, but then i found 2 empty adapters or whatever they're called and i followed the wires from the o2 sensor and they go through this adapters anyone knows what these are or where they belong (just bought the car) or any ideas what to do next?.. pics below
