Default Smoke and misfire

Hi people I need help with my Subaru my95 wrx turbo.
It has a rebuilt sti8 bottom end which has done around 7k
Updated head gaskets and rebuilt heads.with a gt35 turbo.
I took it to the garage yesterday for fuel and all was fine parked it up and went to use it again today and started but sounded very odd like a missfire and smelt really bad of fuel so left it running for a min and then when I touched the throttle it smoked lots seems to be white smoke.so took it for a drive up the road and the hotter the car got the worse the smoke got and also struggling to get boost it smells like burning oil now but any advice before I start ripping it apart I checked the plugs and coils and all was fine ..???

if there's still lots of smoke when the car is warm it sounds like headgasket, get one of these http://www.ebay.co.uk/itm/UNIVERSAL-...-/151046876264

or a blown turbo.

Take it back to the guy who built it! Who fitted the turbo once it was repaired?

Im not an expert somebody more knowledgable on here will correct me, but I would take the hose off and prod the wheel, see if it moves.

But if it was the turbo then surely it wouldn't make the car run lumpy ??

if its lumpy on idle i would get a compression test done, I had this on a classic, on mine you could feel it in the drivers seat.

Low compression on two cylinders, one was really bad.

update...
I started the car today and noticed that it smelt like fresh fuel coming straight out of the exhaust,so I looked under the bonnet and noticed that there is fuel leaking from around or in the turbo and is quite bad I put my hand there and it was pretty wet from the spray of fuel any idea what can cause this,and I take it the smoke coming out when warm is unburnt fuel coming straight out of the exhaust as I say it is not a little bit of fuel any help would be appriciated

It's not mixed but it's just fresh fuel and quite a lot of it aswell

Stuck injector? I would probably take the plugs out and look for a cylinder full of fuel.
