So I have started purchasing all of my mods to install a GT2871R on my s15 SR. I do not have all of them yet and my stock T28 has now gone out. I found one thread ( https://zilvia.net/f/showthread.php?t=348023 ) that really describes how these two turbos kind of compare at ?stock boost pressures?. Most threads just say you have to upgrade seeming to consider only increasing psi and fuel or just state run less psi because it seems safer. I would like to install this turbo for the time being only running it on stock boost pressure until I can get the parts and the stand alone wired in but do not want to damage anything. I have tried to search these forums and other websites for clear information but that thread above is the only one I have found with what seems to be good information pertaining to what I am looking at doing for the time being. I also understand people get very irritated at ?dumb? questions where people could have searched the forums. but I have tried and just not found any thing really other than what I have stated above. And that thread is almost 10 years old as well so I didn?t want to post in it again. So I guess my real question for those who really know these kind of things in and out is....... are the things stated in that thread correct? Also the reason I am asking is I already have the GT2871R
