i want to eliminate the mech/tuner factor in spec calculation, only need him for disassembly and reassembly of the whole engine. deal with the engineering shop directly, buy my own spare parts. just an idea, thought it might help save some bucks or complications :hmmmm:usually your mech/tuner will do the specs/calculation needed and send to engineering shop. then your mech/tuner will install back and tune.
Upwork got a lot of mitsu kaki send there. i got to know of the shop from din6a12. went to his shop to buy gsr brakes and my car that time just swap engine and having problems. he suggest to go to upwork. so i went there, after discussion and checking i decide to do top overhaul. so far until today engine got no problem. they did a good job.
that is a good first hand review from you, will surely put em on my list. much thanks!
