so heres the story..... i was getting out of work (best buy) and tried to start my car. it just kept cranking and cranking but no spark. after 3 hours of wondering if its a fuel or spark problem i had my friend tow in back to his house. i took off the spark 3 days ago and found that the leading and trailing spark plugs for the front rotor were burnt and completely foul. replace all four two days ago and jump started the car and drove it back to my house. after i jumped it i had to ride the gas to keep it from stalling and it was backfiring a lot. after i got it warmed up everything went pretty much back to normal until i got to the main roads. i had dwindeling boost power (except for one time that i floored it). later that night i found a 3"x5" puddle of black oil at my friends house where my car was parked. i checked my oil when i got home black and low. i was gonna do an engine flush and an oil and oil filter change but i dont think that will help the boost problem. one speculation might be that my timing is off.

here are my mods:
intake, downpipe, exhaust, racing clutch, FCD, koyo radiator, and a turbo xs boost contoller which i recently boosted up to approx. 10 psi.

PLEASE HELP!

 

Slight note.

You're going to blow your engine without all the nesscessary fuel upgrades.
