Following my thread https://www.dsmtuners.com/threads/bolt-on-turbo-recommendation.534633/ i want to post here my experience, information and the results from this turbo.
Currently I'm still road tuning and because I don't spend a lot of time for the car it will take few weeks for the end results. Right now I'm almost done with the basic tuning, city driving, cold starts and idle. Today i was able to do few pulls with 4th gear trying to see the minimum RPMs for full boost, tuning only with pump gas which is 98 octane in Europe, like the 93 RON in USA. I can say that I'm more than satisfied! With a 64 lbs/min capable turbo, journal bearing, at affordable price, I'm seeing 20psi of boost at 4350rpm! And this wasn't the maximum, I just didn't have enough time for more pulls.
To get the correct warm oil pressure at the turbo which is MAX no more than 70psi and MIN more than 20psi at idle, I use oil feed line from the oil filter housing with -4AN lines, a 0.045" restrictor, and a Turbosmart Billet Turbo Oil Feed Filter with Mobil 1 0w40 FS. I also have the oil valve relief MOD and deleted balance shafts.
