I have the gt3251r from my sentra still. I was going to sell it, but it has less than 500miles on the CHRA and the housings just got polished/heat coated. I was wondering if I should keep it and use it for my motor build project or sell it and get a bigger dbb t4 turbo later. I haven't been able to find a good compressor map for it, so I'm not sure how well it'll work with the 7m. Specs are: t3/t4 hybrid, 57 trim, .63exhA/R, .70compA/R, 3" inlet/2" outlet, oil cooled only, non-bb, vband flanged, external wg. What do you guys think?
