You have a boostleak, i build gsx's my roommate owns 4g63 power, give me your email er cell and i will send you a boost leak detector you hook up to the turbo inlet and shoot pressurized air into it and if you have a boostleak it will leak out of the engine somewhere that is your leak you replace the seal or hose and blauw the car is fixed, hook me up with blue feedback since im going this far out of my way. the reason you cant get past 2500rpm is because unmeetered air is being let in post maf sensor and the ecu is trying to richen up the engine which is causing the black smoke and probably a strong smell of fuel. my current dsm is the 9th one ive owned =) they break alot lol easy fix though.

Rings maybe?? Run it till it smokes then remove a couple of glow plugs & inspect the bores to look for evidence of oil. Does it smoke when u first start it too?? Or only once it has warmed up??

1990 mitsubishi eclipse gs 2.o turbo. the car crank no start


Sounds like a failed or disconnected ignition coil wire.
Hook up an OBD reader and crank the thing for awhile watch the reader for the code. Look up the code number . You may need a book for your car to do this. The reader will tell you what's amiss.

Car dies if accelerator is not engaged


the starting problem could be head gasket if it got really hot..... black smoke wouldn't be oil, and gas would stink but not black smoke if it's old, it wouldn't really matter if it had been sitting for 4 months. black smoke is probably caused by a gas mixture problem, or maybe a stuck fuel injector.
