The cost for me was
* Original rwd bigport motor + loom $1800 (ouch)
* Rebuild $1100
* Mechanic to install $2500, includes vn pump and baffles welded in tank, new h/duty clutch + flywheel ground, all oils and fluids, new fuel lines and filter, air filter and full stainless exhaust.
General repairs, running costs + touch ups $500
All up $5900.
Wouldve been cheaper using cheaper motor and parts and not having the rebuild, but at least i now it shouldnt brake.
