120k in Japan

[NY2Tokyo]

After 2 days of research I finally found a shop in Japan that specializes in the Fairlady Z. Now the service that they offer includes:
Timing belt · Timing cover bolt · Water pump · Water bypass hose & Water pipe · thermostat · tensioner · idler pulley · air conditioner idler pulley · crank pulley · inlet water pipe · outlet water pipe · water temperature sensor · water temperature sensor · fan / air conditioner / power steering belt · camshaft oil seal · camshaft front cover bolt · Spring tensioner · O ring · Front crankshaft oil seal · crankshaft sprocket · crankshaft sprocket plate · key · radiator (Twin turbo is recommended 2 copper layers)
· Radiator upper & lower mount · radiator cap · radiator upper hose · radiator lower hose · radiator reservoir tank · AT car is oil cooler hose · alternator (rebuilt)
· LLC exchange + treatment
What would be a reasonable price including parts? Because it costs almost as much as I paid for the car. But those guys work exclusively on 300zx so I know I'm in the right hands.

Now the other option is to get the 120k kit and do it myself. I have basic mechanical knowledge but never did a job like this. I will be leaving Japan this year and moving to Italy so I might never get a chance to take the car to the specialized shop again. Any recommendations?

if you can afford it pay them to do it. if you cant then do it yourself. not sure if it was particularly hard for me (engine was on a stand,and i have yet to actually start the car.i wont lie im worried about if i did it right or not. i screwed up timing in the past on a non-interference engine,) there is plenty of reference and how to on the web. i would imagine the cost to be around $1200 U.S dollars maybe more i dont know i never looked into having a specialty shop do it. regardless when you move you will have to do it yourself eventually unless you find another specialist
