It almost sounds like your "friend" is selling you his left overs from a swap.
What I mean is he is probably running a GSR block w/a B16 head right?:wink:
I'm kind of siding with others here and telling you to be cautious about buying potentially damaged parts.

That is what it sounds like to me.
Honestly if it were me, i would stay away from it as it may be more trouble that it would be worth.

because changed body style in 93
and the 93 teg is the old body style, and that was a obd0 style of gsr! right!!

acura goes
86-89 pre obd
90-93 obdo
94- what ever i dont know acura well which is obd1
correct me if i am wrong please!!!

Body style has nothing to do with it.
I believe it goes like this:
86-91 Integra - OBD0
92-95 Integra - OBD1
94-01 Integra - OBD2
