Wiseco pistons + Stock rods?

[Lopin18]

Quick question here:

KA24e stock

i can buy a nice set of Wiseco pistons for the KA24 (Guy ordered K24 pistos and got KA24 lol noone uses ka24s here in the dom rep)

so can i put those wisecos on my stock rods??? im going turbo with low psi so i figured having nice pistons at least would save me from any Ringland problems...

it workS? Thx!

I don't see why you couldn't.

If you can wait a little more and save up some more money, you might want to do everything at once. Such as rods, oil/water pumps, all that good stuff.

Ill see how far i can go but for 150 dollars those pistons are a nice addon, but im ready tight with the snail, tunning stuff, and manifold fabrication etc... :P

Thanks man

If you're going to do pistons just get rods as well. Trust me on this.

It isn't going to be just $150 anyways. New pistons require that the cyls be bored and honed, the bearings clearanced, the rings fitted, new headgasket at a minimum, assembly, etc etc etc. You can probably do some of it on your own, but definitely not all. ...So you're talking machine shop labor + + + + +

Once you start replacing lower end parts you're in a whole new ballgame, and my experience has been if you're going to do it- do it right or dont do it at all.

^ Amen hallelujah!!

Spend another $400 for some eagle rods and you wont have any doubts when you hit 20psi. Also increases you car's value having a 'built motor'.

You can use stock bore pistons, use a cylinder hone and replace the bearings with factory spec stock sizes as well. I've swapped out pistons without coming NEAR a machine shop.

It should be noted that the rods are the weak point, NOT the pistons.

But I agree with the consensus...swap all or none.

+1, if you're putting all that money into it then do it right. There was a guy on the forum who only upgrade piston and kept rod stock. guess what happened, happy boost and Booom bent rod. ended up costing more.

Thats what Foster (Fiznat) did. Bought a full standalone ecu, had alcohol injection and a nice setup as far as turbo and mani go. But only upgraded the pistons...a short while later, like a month or two...he tossed the #3 rod through the block.

A few months after that, I did the same thing.

I can relate, i ordered KA24 bearings once and got K series honda bearings, man was that sweet!

Cory bent all 4 rods at least twice, rods are def the weak link. As long as your tune is good the pistons will hold up.

If you can get a good deal on them sure, go for it. I would just do a stock block motor and keep the forged pistons till you have enough cash to do a forged short block. Get another Ka, build it up, and swap the engine in at your leisure.

Will do, i have 2 engines right now, both running, one is mounted KA24e NA Drifting it right now lol, and the other one is in my house.

Lol i got some pretty heavy duty friends here who assemble sr20, rotaries anyhting, mech tech guys , right now im gonna low boost turbo my current engine hitting 6-8 psi as a beginning project and ill be building the other engine as i go.

If you get a turbo that will spool fast enough, you can lower your rpm and reduce the stress on the rods. That way you can run a butt load of boost, make good power and keep the stock internals.

RPM kills rods faster then torque imo. When you add both, you get a bad combo.

Which is another reason I decided to go with a supercharger. I'll run a ton of boost but keep the rpms to a minimum. Say 6200-6500 max. I dunno, we'll see what happens.

Yeah, its logical that the friction of high rpms will stress the rods a lot more on the temperature fact i suppose?, plus i want the engine for drifting so i prolly will go with a Rb20 turbo or a t25 to keep it simple and safe

[480sx]

t25's your best option IMO, they are so common in the Nissan world. Cheap, and easy to get.
