ok i just drove down the street (not Boosting). then i hear a cling noise and it slowley dies. i am able to start it ,but, now there is smoke out of my exhaust which there has never been. i checked the spark plugs and there all good. What the hell could it be??? this is for an s13 sr20 with stock turbo


just removed the valve cover and it looks ok. unless theres something specfic i should be looking at?

well i put the valve cover back on and started it up, and when i started it it fired up fine, no smoke no bad idle...Nothing! So then i gave it a little gas and then it started all over again. Pouring out somke, bad idle, ect. im thinking it may be a piston or something internal.

vac is at about 8

ok i took off the maf sensor and it started right up, i let it idle for about a minute then went to test drive it and it wont go past 2500rpm. im using a stock maf

it wont go past 2500rpm because its in safe mode from the maf being disconnected.
