not all s14 t28's are bb and not all s15 t28's are bb only sum. do a search on google to get specific years and model numbers. the difference is very minimal though between them

i think the zenki s14 sr's are non bb but the kouki's are

[teddy]

All S15 turbo's were bb. All jdm s14 turbo's were bb as well. There were s14's that had journal bearing turbo's, but weren't jdm s14's.

u are of course wrong. automatic s15 sr's DID NOT have bb turbos. only late model s14 sr's had bb turbos dont matter where the fuk they from. early year s15 spec r sr's had bb turbos then they stop making them with bb turbos. google it there is a whole discussion on an australian forum.
