Here is my situation. I just swapped in a jdm S5 TII into my S4 N/A. The engine has good compression and no coolant issues. I used all of the S4 electronics and went to premix. When I take the car for a drive it goes just fine without a problem. After I park my car and try to restart it after it is hot the car wont start, it just turns over. Not only that but the turbo smokes also. The smoke is almost a grey. It doesnt smell like burning oil, coolant, or gas but instead it smells like it is just getting really hot. I am thinking that my injectors are leaky causing the car to not start when it is hot and causing the turbo to smoke but I am trying to varify this. When I finally do get the car started a large cloud of gas vapor comes out and this is why I think the injectors are leaky. My question is: does this sound like the injectors are leaky?

 

I dont think the snap ring for the oil on the turbo is bad otherwise the smoke would be blue.

 

I fixed the turbo smoking problem. It ended up being the breather for my oil catch can wasnt large enough causing the crankcase to not ventilate properly. I am still unsure about the hot start issue though.

 

hell man my tII swap ran fine until i took all of the emmissions off and after that i have always had hot start.

 

I removed all the emissions also. It kind of sucks having to wait to restart my car after like an hour.
