nitrous is something you could get away with on a newer engine...but i wouldnt recommend it on an old 280z. plus im totally against nitrous, and really dont like forced induction either.

a V8 would certainly to the trick :classic:

300zx:

- 222hp (at crank)

- 7.1 (0-100)

- 3212lbs

280z

- 149hp (at crank)

- 9.4 (0-100)

- 2875lbs

to get the same power to weight you will need 199hp (at the crank) it should then theoretically have the same performance, sorry can't find and sites other then:

Thos numbers scared me at first, then I realized they were kph... 0-100 mph in 7.1 would be pretty quick.. Still I have to agree a stock 280 needs more poneys. Fortunately they can find them pretty easy. 0-100 mph in about 10 is not so hard to get , just a few hard earned bucks.
