Bhai I will reply you over here. I overhauled the engine of Mark 2 from toyota airport it worked like a charm though we have sold it.
I have even seen 660cc JDMs being overhauled at toyota 3s.
It's from own personal experience
I doubt suzuki 3s ko basics ka bhi pata hoo. My friend bought brand new swift, during rain the water started to come in from the windshield, the idiots at sethi motors didn't had any clue k ye pani kaha sai aa raha. At the end my friend got fed up and got it sorted out from from roadside mechanic. Ye haal hai suzuki ka bhai.
Khair leave it. It's one's personal preference. I like JDMs more. Peace
