i used GTS behind ford. was 300 for acid bath,bore/hone and deck block. 250 for crank snout sleeve mod, plus ordered parts through them.admittedly i got it cheaper as we sub-contract them for the big jobs. they didnt seem to have done that many skylines but Josh behind the counter is more than willing to have a good chin wag and price up all options. maybe just drop in for a chat.
