aluminum block ka24de - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

timtiminy · 06-07-2006, 03:00 PM

Has anyone thought of the possibility of making a ka24de block from cast aluminum?? is it possible on a proffesional manufacturing level? i like the idea cause of the amount of weight it would save. what are the new ka blocks on the new nissan truck made of, still iron? maybe this could be a possible outsorce to china.

CaoBoY · 06-07-2006, 03:05 PM

why? cast iron blocks are better. 2jzgte blocks are cast iron...how often do you hear about them blowing up? just get forged pistons/rods for the block and you are good to go. you talking about losing some pounds for like 10th's of a second. its not going to help much, if any.

SpeedMonkeyInc · 06-07-2006, 03:42 PM

If you really want a lightweight aluminum engine just by an SR. Of course its possible to manufacture the block, but I am guessing it would be cost prohibitive.

**mrmephistopheles** · 06-07-2006, 04:03 PM

yeah the cost of R&D to produce just one cast aluminum block would be outrageous. You'd have to manufacture and sell thousands of them before you broke even. The cost/benefit ratio is horrible.

tre · 06-07-2006, 04:14 PM

SR's aren't that much lighter

*NemeGuero* · 06-07-2006, 04:39 PM

Why would you want to weaken the integrity of the engine?

silly silly man

Generally when you hear of engine failures, how often is it the block failing?....Unless he is wanting a 2000hp motor he is probably ok. Hell, 2000hp aluminium motors do exist.
The new motors in the Fronteir is the qr25, open deck all aluminium, that'd be a better option then trying to have your own blocks manufactured for a inferior engine.

REDSH!FT · 06-07-2006, 07:26 PM

More importantly, how often are blocks the ONLY thing failing...

Build/Tune your setup properly and it won't be a problem

infinitexsound · 06-07-2006, 09:20 PM

alluminum billet or forged crank would be ideal to me for the KA......

timtiminy · 06-08-2006, 01:46 AM

just an idea, cause i know dart makes the blocks for hondas...has anyone heard of the qr25 being swapped into the 240? i am interested in it.

One of the reasons so much hp can be sustained on a kat is because its a cast iron block.

1Via! · 06-08-2006, 02:06 AM

I want a cast cheddar cheese KA block.

A Spec Products · 06-08-2006, 02:43 AM

how come 240 owners are weight conscious like nicole ritchie

i want helium filled wheels in 4 lug that are $100 each

infinitexsound · 06-08-2006, 03:53 AM

is she still on the yayo? id still bone her tho shes LAfabulous... lol SOCAL CHICKS THEY ALL LOOK THE SAME.....

*NemeGuero* · 06-08-2006, 04:39 AM

Yah for reals.. if 240 owners are sooooo concerned.. maybe their fat asses should just lose some weight instead.

wootwoot · 06-08-2006, 03:18 PM

I have actually still yet to hear of an sr putting a rod through the block but have seen several KA's that have done so in person. Not that it doesnt happen, but there isnt exactly a shortage of sr's in this area either.

timtiminy · 06-08-2006, 03:52 PM

i just want a more balanced car...im not too weight conscious i just like it in the right areas...as for me and loosing wieght. haha i've been trying to gain some. i weigh about 150 so no real concern there. Im sure it could be done but the cost of R&D would be much and the ka24de doesnt have the same poularity as the b18c engines that dart reproduces..plus the cost of the block alone would be a sr swap practically. so there was never a ka24de aluminum block produced by nissan for any of their vehicles..not even the latest nissan trucks? i wouldnt mind a qr25de but it seems like noone has done it and the cost would be high. i cant do a sr swap legally, and i want to stay legal so i'm trying to figure some options which are extremely scarce

infinitexsound · 06-08-2006, 06:19 PM

bufka......< figure that out.....

wootwoot · 06-08-2006, 06:41 PM

Holy hell man. You think having a custom aluminium block would be cheaper then doing a qr swap?? The qr swap could be done legally

**ThatGuy** · 06-08-2006, 06:46 PM

LS1 = lighter than a KA and COULD be made street legal. Not everyone's favorite swap, just another option if you are really bent on saving some weight in the engine department.

Ghettokracker71 · 06-08-2006, 07:01 PM

QR swap eh? Hmm...I'd still love to see this done.Geuss you'd have to use a RWD TRUCK MOTOR lol

basically almost the same thing.... and a 2.5.. but what ever..... finding a rwd tranny would be a big problem unless the KA bolts up somehow... id rather go SR or...stick with the KA..or if i had the money LS1. weight isnt that much a factor....

Ghettokracker71 · 06-08-2006, 10:01 PM

Wait wtf did the QR20DE and QR20DD come in????????? Specs/info please?

That kind of defeats the purpose of getting a qr though?

timtiminy · 06-09-2006, 11:20 AM

i heard the ls1 is a lighter engine but with the tranny and engine combo it actually weights a little more, and i'm in cali so it actually wont be legal cause it has to be from the same manufacture. in order for it to be legal. The QR swap seems feasable but expensive unless i got it out of a wrecking yard and they sold it for cheap. i hear that the QR from the frontier has the rwd tranny, if we were to use the altima fwd QR25de.. im sure there sould have to be some custom fabbing for all of it to work, but it would definately be different.

timtiminy · 06-09-2006, 12:02 PM

this is from a datsun 1200 website...suposedly its been swapped into a 1200.
QR25DE 2.5 liter Nissan/Infiniti engine. Plusses: 13% lighter than SR20DE, 20% lighter than KA24DE. 30mm shorter than SR20, It also has twin, counterrotating balance shafts so it should be a nice smooth engine. The drive-by-wire throttle body should make for easy swap (no throttle linkage to
worry about).

CaoBoY · 06-09-2006, 12:14 PM

qr wont be legal, because you arent using the stock header, or carb approved header. just stick with the ka24de. there's no point in trying to save weight when you run boost, it will compensate. if you do not run boost, it will still be good all motor. you keep mentioning honda motors....did you come from the honda crowd? what is your reason for swapping motors?

Realchaos1 · 06-09-2006, 12:47 PM

QR's are fwd engines... Correct me if im wrong

*NemeGuero* · 06-09-2006, 12:49 PM

Did you read? He thinks the QR from the frontier has a RWD tranny
