You know whats scary, China could cripple us with a trade embargo...Sad.

big vinnie I had honestly not even looked at where you live, no wonder you do so much N/A support... I completely agree that once a fully counter weighted crank is available ~cheap~ we will see way too many 200 plus n/a street rides, the hump has been found just not jumped yet. Get that paper work to them,let them know we want a cheap , strong , accessible crank. Not not but right fvcking now.

Yeah, well... what do you expect? Unionizing and the attitude of the lower and middle class towards education have basically dug their economic graves. You can't run head to head with the industrially developing world carrying that kind of dead weight.

We don't need to loose our middle class, but it does need to be come more educated. Educated enough to act as good liaisons between overseas operations and domestic end user needs. Working closely with consumers to determine their needs, and designing products to suit those needs can stay domestic. But if an email and a phone call can cut production costs in half, logic dictates thats where things are going to move.

Times are changing, and people will need to change the way they do things to get by. Pretending that you can ignore these changes and wait for it to go away will not solve the problem. Still being a younger guy, I am more than a little bitter about the mess my parent's generation has left for their children to solve. -- Yeah thats a bit preachy, and I normally don't spew such things, but i figure someone has to say it.

Anyway, back on topic... I have no problems if i see an affordable fully counterweighted KA24DE crank on ebay at some point in the future. I like US production as much as the next guy, but sometimes we need to go abroad to ensure what we want is cost effective.

I need some information, on production numbers.

What was the total number of KA24e/de's produced for Nissan from 1989-2001for the frontier/pathfinder,Xterra,stanza, Altima, and 240sx? That doesn't include the KA24e/de's produced for the mini vans (axxess).All I need is total engine production.

Wikipedia also claims that there is a KA24de with a 9.9:1 compression ratio, what chassis type was that engine compression ratio designed for? I'm assuming the JDM (R'nessa)...

If i remember right, the 240's KA had 9.5:1 compression... but the altima's and frontiers had different compression ratios (9.1:1 ??). It seemed to vary as randomly as the cam timings. But I (total newb) would think the DE's have identical bottom ends.

As for production numbers... Naturally car production numbers are a start. All 240's, all altimas, etc... But i don't know where you could find the extra motors production numbers.

The only thing i do know is that Nissan loved to run all its factory's at full capacity to make it look like profits from its factories were maxing out... And I know they tended to do this regardless of projected sales figures.

well if ya said whos got the fastest na ka24 then well check this out....http://youtube.com/watch?v=AEmlmJXFEos this guy did hella of a job on his ka.. if anyone knoe what he had up n his motor... give us some clues...

Well I guess I'll be spending hours trying to figure the total production of the KA's. I need the figure so that if in fact this manufacturer decides to go through with production they can estimate a small percentage of owners that would like to own the crank. Which in reality would fall within 3%~5% of the KA's total production (very small fraction).

wow now I see why the resale value of the 97 and 98 are so damn expensive. Looks like Nissan decreased production to raise the price themselves......

AZhitman, sorry for the late reply (not here much) but I was referring to Shawn, whom you may or may not know. He ran the times I posted w/a full interior Altima SE 5 spd (9.2CR) w/bolt ons, ECU and slicks (14.6 1/4).

Brian was never close NA but yeah, has a very quick turbo setup...I've been over at .net forever it seems. My best was a 15.99 & 16.00s (1/4) w/a '93 auto w/full bolt ons and that was some years back now....

Jeremy

Ah, gotcha - sorry. I know of Shawn's car, but not very well....

Y'know, if you ever want a more "meaningful" position, we've got an opening here.

I have been working on my 90 na ka sohc for about 7 months now and the build is coming to an end. I should have it all put together and hopefully dynoed to see what the power is at the wheels in a little over a month, but I am thinking it will be close to the magical 200whp.Here's how I wentelectric fanunderdrive pulleycolt camarias 10:5or6.1 89.5 pistonssi valvespauter rods3 angle valve job and ported, machined as well possibly increasing cr slightlynology hot wires, ig. coil, and plugsrc 270cc injectors megan fprvenom fuel pumpjim wolf tuninginjen intakeobx racing exhaustmegan 2.5 test pipe through to canisternismo mountsxtd 6 puck clutch-Also later on I am installing an e-ram supercharger (800cfm and 1psi boost at wot something like 25,000 rpm nearly instantly)and some form of wot nos (either direct port or a fogger system)my fingers are crossed, but I believe I will be close and after I leave HI I will purchase a stand alone fuel management system and hopefully find someone who I can spend some time with tuning.-Anyone who has seen or heard of a setup like this with known whp let me know.Also later on I will be installing a one piece lightweight driveshaft that should freeup some of that hp.I stuck with the stock flywheel though thinking that a lightweight flywheel really only comes in handy from a standstill. My reasoning being it loses its centrifical force just as quickly as it picks it up whereas a stock flywheel is heavier so slower at the start but harder to stop once spinning. Since I built this car as a drifter I am planning on keeping it around the 7000 mark most of the time so no biggy there.

Whether it sees 200hp or not, it's gonna be a badass ride... Sounds like a sweet motor!

Thanks, I also forgot to mention that it has been balanced so that should equate to less fear of damage in the higher rpms.

It has been a costly and timely venture, but I have become rather prideful in that fact that I am using a "truck engine" and staying na. Plus how many newer rearwheel drive sportscars can you buy for 10,000. -I am thinking that with the purchase of the vehicle, parts, independant and shop labor thats what the cost is. After I am done painting it I will post some photos.Bayside blue, and black hatchbackFor when I instal the engine, what is a good psi to set the fpr at to begin with?

hondas use them.

drewc87 wrote:hondas use them.

I think that is a different engine. I believe one of the Honda K24 engines revs up to 7100 rpm but with a partially counterweighted crank.

Bigvinnie wrote:This experiment with fully counter weighed knife edged cranks was tried before.My friend Steve tried this method and it doesn't work. Once the inertia in the bottom starts rotating to fast the welds snap or crack.....Welding on weights isn't good enough. IPP even recommends that you don't use there cranks for high end applications, street use only WETFTM.

I was looking at pics of a VG crank and the center counter weight is actually bolted on to the crank. I don't see any place to drill into the KA crank, but maybe some smart machinist could figure something out.

found something today that said most all ka24de for truck and fwd came from mexico,and that the 240sx ka's were not, if I dig it back up I'll let you know where 240 ka's were made...... this creates q's that need A's fast, what is (if any difference ) difference,between the cranks and bottom end in general.....

I don't think the cranks are fundamentally different but the blocks are. Here are a couple pics -- one is copyrighted so if there is a problem I will have to take it down.

all the s-chassis were made in fukuoka, japan including the KAs (so yea we have JDM cars lol)...the 94-95 altima was made there as well i believe (read it a long time ago) this might be my first post on here, i usually lurk but i'm an active member of tamparacing.com as i am from Tampa Florida...

My take on this is that a NA KADE making 200whp would be great but for what ? Bragging rights? i am also not one to stifle creativity so i say yes go ahead and try try try x100...

i am not financially able to build a KA-T at this time ( i want to do it right the first time not the second or third like every bandwagon jumper who boosts their junkyard engine to oblivion) so i am trying to harness as much NA hp as possible for street use. i dont have a 200whp goal...200chp would be fine for me as i am doing weight reduction (for myself too haha)...

a few pages back someone (maybe vinnie?) was saying that the cost effectiveness of boost just isnt there (here 93 oct is about $2.75)i know this is a NA KA thread but a local shop (many of you probably know them for putting out "the bandit" in FD) XATracing has a SR20DET powered hatch that the owner has dubbed "The Punisher"...he's a tech for the shop and gets 28-30mpg on a 400rwhp tune...i also believe he DDs this car but i'm not sure

there shop forumhttp://www.tamparacing.com/forums/xat-racing/

a thread about a race that never went down due to complications (this thread has some info on the punisher though)http://www.tamparacing.com/for....html

In order to pull that 28-30MPG he definitely isn't on the stock transmission gear ratio's. I'm learning a lot about fuel efficiency these days and realizing that even moderately gas guzzling engines can get good gas mileage.My Nissan murano VQ35de for example makes more HP than my 240sx KA24de, it's also a larger displacement engine. So why better gas mileage than my 240sx. Well in some cases it doesn't, in some cases it does. When I take my foot off the pedal and keep rev at about 2000RPM, the CVT selects the correct ratio while the engine minimizes it's fuel use actually conserving fuel and maximizing torque with the ratio given through the CVT transmission ( in this respect yes I get better gas mileage at about 27MPG). Now if I put my foot on the pedal I can get my murano down to 17MPG at a constant 6000RPM rev.Now in any case turbo charged engines run richer A/F ratio's thats just a given. So an SR20det on the stock tranny isn't going to be getting better gas mileage than a KA24de that uses the same tranny and uses a leaner ratio. Changes to the differential gear ratio's can change gas mileage as well.

Gas here in California is now at a high of $3.52 for 9/10 of a gallon of 91octane.

shinmei, I'm jdm tyte now fo sho yo! seriously tho, I should not even be in this thread since most involved are runnign the de motor, and I am on the e( a proven over 200hp capable engine) not saying its worth the effort to get it there (n/a) but ,the crank that we have *hope* for will carry over from an n/a build to a boost build,but letting the n/a guys make some decent numbers. Yeah the average bolt on ka will smoke the average bolt on (insert most any n/a 4), but thats partially due to the torque that is made in ka engines. A honda with all bolt ons may crack 200hp but they had to rev nearly twice what a ka does jst to do so. I geuss I'm just saying a fully balanced crankshaft and we could ALL make 200whp(with supporting mods)

vinnie stfu my 4.3 vortec only gets 20ish on cruises

oh yeah agreed a gear or rear change had to of been done to get 28~30mpg at what afr/boost? or is that at like 5 psi and 14.9:1? I can seriously lean out to around 16~17:1 for cruise and dont get close to that. N/A granted most of the time I act like a ricer and am doing fly byes any word yet vinnie

neverlift wrote: any word yet vinnie

Still working and compiling information. I am also busy moderating another forum.I'm just glad that it is spring break gets me time to compile information.

I just picked up my engine from the machinist today. Tomorrow if all goes well I will get the freeze plugs in and it painted so that I can drop it in the car on thursday. Unfortunately I will still have to wait to turn the key for maybe a couple more weeks till Jim Wolf gets my injectors and ecu back to me. Anyways what would you guys recommend starting out at for my fpr. I believe the manual says 37psi, but that was for the fuel pump, any suggestions would be great. Hopefully I wil have dyno results at the end of the month.

One more question. With the #1 cylinder at TDC, where should the rotor be pointing. I think its supposed to be at the #1 plug, but I believe mine is at #3. If it should be at #1 can I just move the plugs around or do I have to remove the oil pump and realign the distributor?

180 - Can you start a seperate thread with those 2 posts?

They're kinda off this topic, and your questions deserve their own thread.

OK, back on topic, and maybe I'm a newb again for thinking this...

But if the KADE is stroked out to 100mm... what does that do to the compression on stock pistons? Would one need custom pistons for valve clearance? Or are we talking custom rod & pistons to make it work either way?

Email sent to Xia Xu Bing today on the research and production for the KA Fullycounter weighed crank. Now I am in search for vendors.I may talk to Chris at AMS since they are world wide. He is a vendor over at the forum I mod.The wheels may possibly be in motion.
