Default ej20K cold weather issues

I'm running my ej20K since july and now that the temperature dropped, I'm having some issue with cold starting and idle. The engine fire, but take too long to raise idle speed. Usually, when you start these at -25C, they will fire up and idle around 2000 rpm for a few moment. Mine take like 5 secondes to go from 500 to 2000 rpm (more like 1500). When it's very cold, it have tendency to stall when the idle speed is too low.

The other issue is occassional stall when releasing the clutch, probably because of the BOV

Could all just be an issue with your blow off valve?

when it's under -20c you dont want that thing revvin up to 2000rpms right away when there is no oil pressure!!!! when its that cold all the parts have more play cause they are so cold! my 20g (running off a 22t comp) revs up quick every start to like 2000rpms when its kinda warm it goes to like 2250 but now that it is like under -10c it is a little slower up to revs!! and stops at 1750 so I am a little releaved about that!!! but just let it warm up for a couple mins than drive it!!! these turbo engines should warm up in the cold anyways right!!?!?!?!

anyways just my 2 cents Jesse

yes and cool off to...get a hks turbo timer and put it on auto mode...it will run longer and use 1/8 tank of gas per fill up but will help in the long run...with my 20k if its at the cold line I ride down the road about 3000rpms in 3rd and it warms up quick...if ur worried about oil than go to royal purple thats what i use. It will leave a oil film on everything that lubercates until the oil gets moving.. my 20k revs 2 about 1800 when i first start it (around -5C is as cold as the engine has been when i start it) but drops to 1200rpms until it warms up

I wouldn't mind idle RPM it the engine would actually climb fast to it and not stall in the first 2 seconds. Once "warm", I mean that the engine has been to normal temperature then cooled down (because it's -20C), the engine actually take about 15-20 seconds to climb to high idle speed.

my car has that too but the ej22t's harness had no conection for it, but I guess the comp tells the injectors to run richer!?!?! it always starts up right up to like at least 1750 then slowly tapers down!! if is has ran in the last 5-20 mins (depending on outside temp) it goe's up to like 2200!!! then tapers down much faster than when cold!! but yeah I will get some synthetic after the next break in oil change (this engine has probly sat for a really long time so I'm rebreaking it in like when new!! might have like 700-1000 k's on the first oil (GTX) 10w30 it was just a bit over full so I drained some out and put some ATF and some more oil in it (to clean lifters) then at christmas it's getting some semi synthetic oil in it for like 3000k's then full synthetic every 5000k's give or take! hopefully that makes her last !!
