Hi guys my turbo is shagged/ noisy bearings and am looking at a replacement, now I know ideally I would put in a new garret core but finances won't allow that and the car has $200000k on it so may not be worth it, any way I have found a cheaper gt3582 copy and was wondering if that would bolt straight up, been searching for the gt3540 specs and haven't had any luck finding them to compare, this is where you guys come in with your plethora of knowledge, the specs on the one I'm looking at are as follows trim 56, t3 flange, ex 82, Ind 61.4, ar70. Will this fit up and if so what sought of modifications would I have to do? And would retune be required? Any input would be muchly appreciated.
