I have a 93 sentra se-r and definatly want to go turbo. Up untill today i was planing on swaping out my sr20 for the sr20det out of the gti-r. Then i finally met someone in my town who ownes another of the early 90's se-r's (there are only 5 in town that ive seen) and he was saying it might be better just to rebuild my existing motor, lower compression, get new cams, and all that fun stuff and just get a turbo kit. His arguement was that if i ever had problems with the gti-r motor that replacement parts might be harder to find because its jdm. My question is are the gti-r motors different in a way that if something went wrong with it that i would not be able to go to an auto parts store and order the part that should have been on my stock motor and it will work. Also if i do opt to rebuild it then i could also replace the any parts that might fail when i start really boosting the horse power. Fyi im hoping to be able to set it up to be able to run at least 15 psi of boost and hopefully get at least 350 horse. There are just so many variables i just dont know what to think. Any advide or info would be appreciated. Thanks.
