tips to building a ka24de for boost

[osofasts13]

hey i'm planning to build my ka24de. what in there do you guys usually beef up to run decent boost looking at 300hp. i know it needs pistons and piston rings, what compression pistons do you guys usually run?? what else do you guys usually rebuild or replace in the block. i know the rods are good, the headgasket will be replaced, the head bolts will be replaced, what else??lifters??valves?? any comments will help.. thanks..

I'm trying to reach 300HP with just pistons, rings, ARP head and block studs and a freshened up block.

Was gonna give you a link to my site... but it seems to be down

I'm replacing all seals, rod bearings, ARP head studs and rod bolts, forged pistons, piston rings, valvesprings, timing chain, water pump, oil pump.should do it...

[mys13240]

are you just getting an oem water pump?

[SSS]

Stock headgasket/bolts should be fine for around 300hp.

Where is the cheapest you have found ARP head studs/rod bolts for? The cheapest I can find them for is $185 head studs and $65 rod bolts. Any cheaper places would be appreciated.

Umm I am not going to do anything. Extremely good management and fuel system along with a complementing cooling system. Really isn't that hard to get 300whp from a stock block KA as long as you have the management to get it up to par.

Just a thought guys.

[andrave]

yes. but I want to run pumpgas and you never know when you get a bad tank.. really I'm just hoping for a nice bit of power that won't leave me on a first name basis with the towtruck guy.

I was gonna get my arp **** from ka24de.com

andrave..how much do you think it will cost for all those parts and install???? i'm also gonna put in a new water pump and oil pump....all together what price am i roughly looking at???

[andrave]

I don't know I don't have most of that yet. I was thinking about boosting it stock till I blow stuff up. that sounds more fun.

BUT I know this has been covered before, search for like "oil pump" in the ka forums or something. should turn up stuff you are looking for. I was gonna stick with oem or like oem stuff, I don't see the need for anything beyond oem except for the pistons, and even then if you watch detonation you would probably be ok.

ARP Head studs for only 300whp?? Go ahead and waste your money. Those bolts are meant for holding like 25psi+, not a measly 300whp, which would be hovering around 1bar. OEM Nissan bolts are sufficient for MOST KA-Ts.

There is a guy that makes 350whp on a stock KA block. Some of you people are going overboard on this internals binge. Fuel/Ign management is FAR more important to engine longevity than forged internals and ARP studs. The only internal work I would do for a 300whp+ setup, if you really wanted to would be just forged pistons, mostly to compensate for the crappy ringlands on OEM ones...

Couldn't have said it better. :ylsuper

Never hurts to throw away your money for better parts though haha. If your looking for a bunch of KA parts for cheap talk to deviousKA he seems to have some mad hookups.

There's some truth in that, but I'd think what they meant was to worry bout your fuel/ignition management first, then worry bout your better internals, meaning, throw away the money for better fuel/ignition, then throw away the rest for better internals.

Not to mention I hear changing headgaskets with ARP studs is a pain, cuz they are hard to get off once they are on.

What about pulling your head. Don't OE head studs streach after pulling your head?

they are stretched when they are repeatedly torqued. they can be reused, but they really should be replaced.

[andrave]

all bolts or headstuds stretch, but I think the question is, are the OE ones undercut so that they are not designed to be reused? because AFAIK the ca18det ones were like that, and I'd think that the ka24 would be too.

[Nathan]

Yeah they are, you shouldn't re-use the stock headbolts. You might be able to get away with it, but better safe than sorry.
