are you getting spark at all? if so, try adjust your timing... if not... at least you know which end of the elec system you need to focus attention on. Also, did you get a new ECU with the turbo? 7mge != 7mgte on several different levels... including compression ratio..

not to mention exhaust would have to be changed...
as well as many others,

but he said he had an N/A and says nothing about a gte conversion

it is nice to hear the whole story....

He did mention he went from 7mge to 7mgte swap... so conversion was done... what was included on the 7mgte and what was missing vs process and procedure maintained and followed during the swap is anyone's guess...

Which are you running the GE electronics and harnesses or the GTE electronics and harnesses? They're NOT mix and match.
