you definitely need a 2nd opinion. i was also quoted 70k for the intercooler leak sa pasong tamo.
dont let them do the "patch up work" which is to epoxy your whole intercooler. it doesnt work. im currently having mine done at erl motorwerx. pwede nila i weld yng leaks kung de na talaga kaya they can fabricate a new one for u ( buy a new intercooler core tas attach it to your old endtanks). sure de lalampas ng 20k depends on the damage.
also, you could try to find a surplus intercooler

not worth it paayos sa casa unless last resort haha. if i were u source the parts outside tas pakabit mo nalng elsewhere, someone u trust (labor nalang babayaran mo). dami kalokohan sa casa. sa parts ka talaga papatayin laki ng patong. try nissan parts banawe.
