well sound like you spun a bearing. i think its time for a new engine. I say spend your motor on another motor rather than rebuilding the D15

 

you can get a complete D15B7 every day of the week for $85.00. Just swap in one for $85 and be careful. You definately toasted the rod bearings as well as the oil pump and crank. Then motor's shot. sorry to say man, but it happens... from missing a shift and putting my D16Z6 back into 1st instead of 3rd I hit 8,992 rpm, which i believe caused me to stretch the rod bolts.... lose oil pressure ...... and just spun the bearings..... it sucks but all i can say is hopefully my Z6 oil pump is still good.... i'm kinda weary to use a B7 oil pump on a mini-me/turbo setup that's already got 150,XXX on it. Even though it is in good condition....

 

jus going to use the z6 block with the d15b head and boost it until i can get another d15b or something.
