Well the turbo should take 2.0BAR, and the first map with 160WHP was at 1.5BAR so lots to go yet! Thanks Phil I use Courtesy Parts which have an interactive FAST layout anyway, but if you can double check a B15 Sentra SE-R SpecV 2.5L 6MT LSD? Then I can confirm the part and check with Nissan UK and see if I can get it imported and bought though a local dealer, just like the bonnet .
