Actually the only option left was 4g93 sohc so the 6a13 had shaved crankshaft and con rod so built it but it lasted a day only, then found out this engine biting the dust. It had a broken intake manifold and missing parts. So after some research found out it was a 6g74 sohc with triptronic gear.
So made my mind for this, since had no other options. So this thing brought the cars real beauty back. 4g93 was piece of cake but this chasis is 1300+ kg so it wouldn't have loved 100-125hp engines.
