im planning on starting a 280z project but dont know what quite what to do in terms of motor. im looking between a 1975 280z and a 1978 280z. ive read alot of forums on people hyping up their original Z motors but not getting to far in terms of horsepower. im open to doing swaps but i want to keep it naturally aspirated and a non-V8. thanks! -marco

 

Please be more specific.

Are you doing this swap yourself?
How much $$$ do you have to spend?
What will the car be used for? (street, track, auto-x?)
HP goal? (150hp? 231490723hp?)

 

i plan on doing the swap myself i just dont know much about the motors that are swappable into 280z's. I have about 3-4g's to spend. i plan on using it on the street and taking it occasionally to the track. im hoping for 250+

 

250+HP, my bad

 

Well the easiest and cheapest choice is to swap in an L28ET. A few quick mods and you're at 250hp.

Other than that, take your pick of engines... most all other swaps will require quite a bit of fabrication, fitting, drivetrain, and electrical work (engineering).

Feel free to search... "S30 motor swaps" has been discussed to death.

 

great, thank you very much!
