okay great story here. i JUST picked up my car today from this engine swap today. (about an HR and half way, its relievent to the story)

i just got a b20b vtec swap. the bottom end is supposed to be built, jdm b16 head with b16 tranny. chipped p28 ecu.

i drove the car 55 miles home and it was fine. was pulling strong and everything..

cars on my driveway and i was reving the car to about 7 or 8k then bam my check engine light comes on, and i see white smoke coming from my engine bay and now my car wont start...

i called the place they said to take out my battery cable and then hook it back up, no go. now theyre telling me to find out what code is being thrown..


does anyone have any suggestions what happened? now the car cranks but doesnt TURN OVER.. i hear it. and when im holding the key for a few second then the check engine light comes on agian. im pretty annoyed with my car...

btw car is obd1

 

WTF are you doing dry revving it to 7-8k?

Engines do not like being revved that high with absolutely no load on them. Sounds like something blew up.

 

Sounds like you blew the headgasket, white-smoke is generally steam produced from the water in the water jacket around your cylinders leaks into the cylinder itself. Something you need to be careful about with these aluminum blocks, they don't take kindly to ridiculous cylinders pressures produced when dry-revving the engine at that RPM. Also probably compounded by the fact that you didn't let any of the new parts seat during the break-in process (Yes, there's a break-in period which varies from 500-2000 miles once an engine has been rebuilt).
