When buying a turbocharger for Nissan Altima 25 liter does it have to be the whole turbocharger system or can it be just the turbocharger alone.?
You would have to buy a whole turbocharger system. I am uncertain if a kit is even made for the Altima 2.5. If the Altima 2.5 is a manual, then the transmission is quite capable of handling up to 300whp. The Altima 2.5 shares transmissions and engines with the Nissan Sentra SE-R Spec-V which has the QR25DE.If you meant the Altima 3.5 with the VQ35DE, then I do believe there are turbocharger kits available.
