4k for me... (doing own labour)
surface, bore, hone, dip clean $4-500? (got ripped a little)
crank linish $ 50ish
Gasket set $500
Main Bearings $200
bigend Bearings $200
Rings $250
All new cambelt stuff $300
also had lightened/balanced - HIGHLY recommend that. $150
Replaced rods with forged $500
then new fluids/filters/3bond/assembly lube/coppercote/weird tools (24mm deep socket/16(?) allen key
and chasing electrical gremins (new tps/afm/ICV) $700ish
IIRC - most places charged around 4k for a standard rebuild, reusing rods/pistons, based on you giving them a long block, they giving a longblock back. est about 6-8k for a standard 'strong' build (so closed deck block, forged internals), and 10k upwards for a monster (anything special). probably add another 1k for someone to pull motor out, strip (send off) then reinstall fresh motor
