KA24de engine overhaul

[IchigoMae]

I am about to build my blown ka24de, i need to know wat common engine parts i need to replace, for example, water pump, timing chain etc. the engine has over 100,000 miles. thanks

Obviously, pistons and rings, camshaft, oil pump, distributor, valve stems, guides and springs, retainers, head gasket, head and main studs, depending on situation the sleeves, rods, main bearings, all other gaskets like the intake manifold gaskets, and so on.

sleeves there are no sleeves...rods are fine, cams are fine, distributor and studs should be fine also

the cams are hard as hell they are fine...no need to replace those..jus clean them...same with rods unless u put a lot of stress on the rods

Hey brutha, I said "depending on the situation" which means in most cars cases, no need to stress. When performing a rebuild, complete that is, what I stated is recommended, that is if you want to start fresh. Why do a half *** job when you can go all the way for a better overall investment. I won't even go into the details of my experience, so i will spare you that. But, you are the pro, not I. :D

you shouldn't need to replace your water pump or timing chain, but you can if you want. I'm not. You probably want to replace your pistons, rings and bearings if you are tearing the motor apart. If you are running low boost, then you can skip the pistons. but the rings and bearings are wear items and should be replaced with any build. get a nissan headgasket from a dealer, that's the one you want. You may need to replace some timing parts, like the plastic guides and such. You may want to replace the oil pump (if you are replacing the water pump) and oil pan gasket while you have the motor out. Your rods should be good unless you bent one, normally they are not replaced if they are in good condition. Your head should be fine, I would not worry about it at all.

Whatcha pushing under there? Anything special, or are you stock right now (besides the exhaust which BTW, looks good).

What kinda rebuild you want? Turbo build or stock?

The only reason you would sleave the ka24de is to run some huge boost

www.ka24de.com

You can get a high flow water pump... not a bad idea
I would upgrade the cams and do a port and polish to.

are you doing it or paying?

its gonna be turbo ofcourse. i plan to be around the 300hp range. after having a taste of a turbo 240sx, im not gonna go back to na. ive already purchased my pistons. now why didnt sumone give me a link to that ka24de.com website before i got my pistons. why dont they freakin put that site in the links section. non of those dam companies in the links section hav pistons in stock. dammit ok im ranting now. i cudda saved me sum cash. im not gonna buy conrods, too freakin expensive, i kno its gonna kick me in tha azz in the long run.

Hey man, don't skimp on the connecting rods. You'll be ****ed when you have to buy another block because you snapped one of them and it went through the wall of the block and destroyed all your fresh new engine parts. Just my $0.02. Good luck.

Well. If its blowen up already.. I would say get everything you could want right now. It may take longer and more cash... But it costs more to do it twice. I should have got a spec 3 clutch when I did my flywheel. now i'm kicking myself cuz I will have labor twice! grr

Just my thought on this.

(My idea if you care)

My idea for my car is.. Build the engine to handle 450+ hp then drop in a T25 for insta boost 300hp for the street. Then when you want that extra kick have a 100hp shot of Nitrous. Just one of my ideas. I think it would work out good... Maby even boost to 350hp and then the Nitrous of 100hp.... That would be fun! may need a bigger turbo tho. I duno turbos well.

I was under the impression that if your stock rods didn't have any stress marks or any signs of damage then, from the factory, they are very stout. They are already shotpeened from factory also. (someone help me out here...I'm kinda out of it...:doh: )

Not sure how strong the stock rods are, but everyone I've talked to or read posts from say that the stock bottom end on the KA will not hold much over 300hp. Doesn't the engine have a lot of miles too?
