The KA24 is a larger displacement four-cylinder motor. It was mainly built with low-end torque in mind. It also uses a long piston stroke to achieve its torque. This prevents it from having the high rev limit that is seen with other Nissan four-cylinder motors. With the basic bolt-ons, you can expect to see an additional 30 whp depending on the condition of your engine. Don't expect any huge horsepower gains from inexpensive NA modifications.
why would you even keep KA24E??? Get engine swap, go for KA24DE, SR's, RB's.

KA24E's are crap IMO. I'm rockin' my KA24E for now 'till I get a G, then swap that s*** out of there.

It's just not worth spending money on a KA24E......

Stock internals shouldn't be pushed past 300-350 whp, and that's with good injectors and supporting mods. Anything past that and you start running into issues with variation in supplied components (like micro-cracks and other grain-structure abnormalities in the rods/piston/block/cranks).
