Whos got the most powerfull NA KA?

[Shift_Kouki]

Yeah, I saw reality a while ago... My budget involves keeping the stock crank and rods. All part of being in college and not having a job while I study full time.

I was just wondering if there were documented cases of a KA being stroked w/ custom cranks... So one might be able to see if it makes more sense (as I suppose it would) to take the dimensions resulting from the custom crank and other things to be more in line with the FJ's specs of 92mm bore and 88mm stroke.

-- Man if I did not phrase my previous post well at all. I also cant remember if the above statement has been covered already. But thanks for the link, I had not come across that previously.

Well, vinnie, is Brian Crower not making the 2.65L kit anymore?

its advertised in all the magazines as coming soon, if at all.

Last I know they have been advertising that kit for over 6 months and I still haven't seen any documented builds using this stroker kit. I haven't cared to call crower on it either. I also don't care for the stroker kit since the KA is naturally stroked already. Increasing the stroke shrinks and limits the RPM range. The whole purpose to use a fully counterweighed crank with stock stroke would be to increase it's rev range. Stroker kits just seem like a joke for an engine taht is already stroked too much. Probably why crower hasnt released this stroker kit yet. The kit probably isn't showing the results they think it would of....I am surprised that even IPP claims these big numbers for there stroker kit yet to date still no dyno. IMO strokers are a joke and then you would have to buy a new cams for the rod/stroke ratio. It's all nonsence.

Even when people convert a RB30 block with RB25det head, it no longer uses the CVT and it limits duration of the cam placement and timing. (just an example)

[DjPantsSpecR]

i really, really couldn't agree more.

Especially about why this kit is still advertised as coming soon... it seems fairly obvious they are either having problems, or they are finding they have a 2000 dollar pile of parts that does little to nothing.

I'm fairly certain in your pursuits you've talked to someone overthere, i'd be interested to see wtf is going on. I definately dont want one, but i wanna see someone build it.

and unfortunately, i've decided to rejoin this thread after many pages. I dont know what has happened to my fabricator, i should have had a working intake manifold two months ago. i'll let you know vin

[AZhitman]

DJ, I hope you can make SEMA / AAPEX with us as well...

Hey Guys,

Before you criticize Brian Crower you'd better polish up on your reading and math skills. If he is reading this thread he is probably laughing his ...

Well, you get the idea.

Last time I checked, 91 is less than 96. Remember that stroker motors go both ways.

NISSAN KA24DE 2.65L STROKER KIT BC 4340 billet steel crankshaft (91mm stroke). BC 4340 steel Pro Series billet rods w/ARP 220,000 psi fasteners. CP aluminum forged pistons (any bore size, any compression ratio). 9310 nickel carbon steel alloy wrist pins. Ductile iron plasma top rings, tapered second ring, low tension oil rings. Typically includes aluminum buttons/rail supports (not locks). Fully system balanced and ready to install.

Kit # Crank # Rod # Piston # Desc. Coming Soon - Spring 2007 - Call to preorder!

The BC stroker kit for the Nissan KA24DE engine incorporates a 91mm stroke, steel billet crankshaft. Depending on bore size that you decide, the BC kit will take you up to a 2.65L with a safe 102mm bore. The KA24DE kit utilizes premium steel billet connecting rods. As usual, each BC kit features custom CP pistons, wrist pins, full ring pack and buttons. Big time horsepower and torque gains.

'Course, Brian should do some checking too.

I only get 2635.5 cc with the values swapped. 2974.3 cc as is. I like the latter anyway.

Maybe this is Brian's secret method -- baffle the masses and proceed in open but still hidden product development.

Might be that he uses that as a filter to see who's serious. Something to think about.

[DjPantsSpecR]

good, good eye Kevin.

And AZ you know i would LOVE to go to SEMA, but i'd have to drive my new drop top with only 118k all the way there from Minneapolips. i wanna go BAD. i would love to pull something together and make it, i'll let you know Greg.

[AZhitman]

No reason to drive - Fly in, we'll get you from the airport and give you a place to stay.

[DjPantsSpecR]

HA, i jsut looked its from Oct 30th to Nov 2nd, this is something i might actually be able to do, and i REALLY appreciate the opportunity Greg.

i'll do everything in my power to make it.

[dRiLstar]

i might be swapping a dohc over my sohc but i wanted all motor how fast u think it will be?? and if i turbo it a big difference??

[DjPantsSpecR]

SLOW DOWN. your post sounds a little crack crazy.

all motor? well if you're a flippin baller, somehow figure out what you're doing and use the correct combination of parts adn no doubt some custom work you'll run 14s all day. with gears adn slicks high 13s wouldnt be unreasonable.

if you turbo it and it doesnt explode it will undoubtably have more power than anything we're building all motor these days.

Hey Guys,

The only math I need to read comes on a dyno graph. Granted a fully counterweighted stroker kit cost a lot of money. If people are going to be spending an enormous amount of money on a product he needs to back up a product like this with proof. I still say that the stock stroke with a fully counter weighed crank would make better linear power and would be more cost effective. I would definitely love Mr. Crower to come to this forum to present a dyno for this assembly.

Or wait minute maybe Brian realized he needs new cams to work with this stroker kit, how much more will the bill tally too.....

I think his ad is pretty clear that the buyer will be determining the bore size, compression ratio and tacitly the cams -- so infinitely many combinations are possible and a dyno would be meaningless. The customer already knows or should know that large gains are possible. If he or she doesn't know this then perhaps designing an engine is not for them and he or she should pay a shop to build them a motor.

Why not ask Brian if his kit actually has an increased or decreased stroke? That would be a good thing to know.

Just thought I'd let people in on a 177rwhp ka with intake, header, exhaust, and tuned for 104 octane (94 octane and stock ECU yielded 145rwhp).http://www.pdm-racing.com/features/court240.html

cool, 500 posts.

Now just imagine if they removed the SCV's from the OBD1 manifold that would be about 6~7 more HP. Also EGR block off is about another 6HP.... Easy DIY self mods to put the KA at about 190whp...... Add a high lift cam and you have 200WHP, can anyone say Brian Crower stage 2......

PDM just mimicked me from a thread I wrote LAST YEAR!!!! http://www.club240.com/forums/...30440

I guess I need to eat my own words when I said a stroker wouldn't work well for the KA.

DEAD thread revival!!!!!!!!!!!!!In speaking with Chris about the fully counter werighed crank shaft for over 3 months now. He has decided on a group buy. If we get 10 people we can each get a crank for $1300 out the door!!!!!!!!!Chris said that he started a link in NICO and KA-T as well but I can't find those links...http://www.club240.com/forums/...26725

[bone_stock_240]

Here is the link to it on Nico. I was suprised when I saw it that you hadn;t jumped all over the thread yet.

[Bigvinnie]

I'm not always in the KAdet section of NICO....NA KA mostly...

[neverlift]

we should know fairly soon, yellowcar ahs the kit as well as cams, he said he pretty much bought all b/c had to offer. I kinda down talked it though,for boost. I like the idea but IMHO your getting a crank thats balanced.... I had missed the crank thing though vin, glad this got bumped, I may do that with my rebuild in feb. ish

[Bigvinnie]

I may do that with my rebuild in feb. ish

Chris might or might not be selling these in February. Get it while it's hot..... It's a custom modded crank you won't find anywhere else.

sorry if i missed it earlier in the thread but will these cranks be available for the kae engine or only the de. It is the only part in my engine that hasn't been replaced and believe that it is the crown jewel to get the engine safely over the 7000 rpm markthanks

As far as I know Chris has only told me that they are for the 240sx DE engines.

This was a good thread, shame it petered out.
For some reason page 7 doesn't display properly for me. The menu box on the right side covers the text.
Would it be possible for someone to fix this?

[Ajax]

Well, its not exactly Learnd'd. I had totally forgotten anything about this thread- actually, I thought I didn't know anything about it, until I discovered I had posted on the previous page...
FYI, next winter will be when I get a custom header and replace my ugly exhaust. Retune to follow in spring at AMS (hopefully). We'll see what happens.

[1Bob]

Am I the only one that can't read page 7?

How do I get it fixed???

[biggie]

Must be your browser or something, I don't see the problem.
