going all motor

[needmorenissan]

Need ideas to raise horsepower going all motor, thinking of raising the compression but dont know where to get the pistons, need help.

[CMG]

Expect to cost twice as much as an Sr with about half the HP.

Cams, pistons, rods, balancing, lightweight flywheel and pulley, deck the block, shave the head, valve work/oversize, porting, headers. There are decent options available to build a more legal motor than an SR swap.

Are you doing the work yourself? I am currently building an N/A motor, but I had my machine shop do all the machining, balancing, and order all my parts (90mm pistons, bearings). If you're machine shop does upgrades, they should have all the resources needed.

Not ****ting on a N/A KA, but I hope you're ready to spend thousands of dollars and probably never break 200whp.

ls1, cheaper and more power.

the easiest thing u can do to make hp is turbo the ka it would be cheaper than building your whole engine with alot more power (as long as your motor is running fine now and has good compression) if your motor is messed up get a sr but it all depends on your hp goal if u want a 400hp engine build yours then slap on a big turbo if u only want 200-350 turbo your engine now or throw in a sr with a few upgrades

Why does everyone assume that maximum HP is the only way to go? The OP never asked whether you guys felt it was a good choice, he wanted to know where to get the parts. You all need to get the f*#@ off your SR high horse and realize that putting in a used, illegal, turbocharged motor from Japan does not solve everything.

Try the KA24E/KA24DE forums for better answers. The lemmings on here only have a single answer for every engine question...SR

thanks man ill try that

It does too.

Seriously though.

Look into a stoker kit, the KA already cant rev, might as well make as much low down as possible. Then have the head built, fully built, with a full port and polish. With the motor all squared away research manifolds. Individual throttle bodies might be a good idea, or a custom plenum. General consensus says that much of the restriction in the KA is the intake manifold so choose carefully. Also remember not all intakes are created equal, some will shift the powerband up, some will help with torque production. Keep your goals in mind so one mod isnt fighting another. A good exhaust manifold is also a good idea, and just like the intake, different designs help with different things.

You should also decided how to tune it, full standalone, piggyback, daugheter board, or rom tune. There are many options, and Im sure one will suit you.

You will also need to improve the ignition system with some sort of aftermarket coil.

All that being said, building an NA motor is expensive, and if all out power is your goal, there are far better options. Do the research, settle on a budget, and know what you want.

No one said anything about the SR. I'm a KA-T guy, I wouldnt buy an SR. I assumed that he was looking for horsepower because his first sentence reads "Need ideas to raise horsepower going all motor". Maybe I read it wrong. I think that YOU need to chill out a little bit and realize that we're not ****ting on his idea, we're just making sure he knows what he is getting into.

Um, yes they did. The OP specifically asked for recommendations on N/A parts. The FIRST two responses were SR or Boost...Typical NICO lemmings.

[needmorenissan]

is it better to raise compression or to lower it?

[xekushnr]

Raise for N/A, lower for turbo. You'll have to run a higher octane fuel, but it will produce more power.
