When was the first Altima made?
1994 it replaced the Nissan stanza
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.
1994 Nissan altima doesn't have a timing belt. The 1994 Nissan altima has a timing chain. Which is much more durable than a timing belt. Answer If you think your car is out of time...check the distributor first. When it goes out it sound like the car is out of time. Answer The engine has to be removed to replace the timing chain; expect about $1,000 for labor alone.
