engine swap 2.4 to a 2.8

[71datsun240z]

hey all which 280 engine can i drop into my 240z? which year ? because i want to have a 5speed and a bigger stock block

Any year 280 block will work from 75-83. The better block is the F-54 from the later ZX's. It has siamiesed cylinders (more webbing between the cylinders) and is purported to be stronger than the earier L-28's. Any 2.8 is going to be an improvement over the 2.4 so the F-54 is not a mandatory block.

As far as the 5 speed, it will go behind any of the L series engines so an L-28 isn't mandatory for that swap, but a displacement increase is always a good thing.

Yep, "ditto" to what Keith said:p

and will the triple dell ortos fit the 2.8 engine? are they universal between the 2 i thought they were if they arent ill stick to my 2.4

because right now i wanna build with the engine i got and the only reason why i wanted the 2.8 was yea because of the power jump but the 5 speed i thought was only 4 the 2.8

once my z car is done i plan i buying a seperate car with extremely good gas milage and takeing the z from where it will be to a whole new lvl 3.1L but thats waaaaay in the future

The triples will bolt up and work fine on the 2.8, the only thing you may have to do is to re-jet the carbs.

As far as the transmission goes, if it came from an L series engine it wil work, L-24's, l-26's and L-28's all have the same bolt patterns.
