All motor KA

[liquid_cool]

what can i say i havent said before.....here goes......alot of tuners look for massive fast horsepower adders...horsepower in large quantitys is fine if your a drag racer on a strait line....(unless your elite and race for a living)...most people cant use horsepower to there advantage anyways..most people cant even take a corner properly...so i dont see the point with spray,or a turbo....N/A is fine for most people who are hobbie racers...i have less respect for people who just power up and do that rolling start **** on a freeway and go fast in a strait line.....of course everyone goes throu that phaze...i have lots of respect for the few who can use the balance of there platform to out manuver the person there battlin.....have'in to much horsepower ruins the balance of the platform...for the 240sx s13,s14 180 to 200 hp...is a good balance when equal attention is given to the suspention...in my opinion..anything above that..just ruins the balance of the ride....if your not a drag racer you shouldent need so much horsepower..as you will have to use more braking abilitys when entering the corner....hence compressing the tires...on a road race..where corners are involved..it all comes down to the tires and how you use them..same with drift battles....N/A for the win...

just my opinon.

hey does anyone know if the s14 stock cams will be an upgrade to my s13 stock cams? More HP????

do not do na ka! i did, and it had bent rods and bearing within a few months.

buy a ka24de for about $300 and rebuild it for low compression and little things internally and turbo it. thats usually good for around 250hp-300hp safely and reliably for a very long time.

The question then, is what did you do, and did you do it poorly?There are a lot of guys on here that have done NA KA builds, and while few of them have made gains above 180whp, I've yet to hear about one breaking down.A bad build is a bad build whther its turbo or NA. Do things right and tune it well and all will be well.

[ss82480]

As for the guy with bent rods on his KA, there are alot of other factors that come into play. Just because you had a motor that probably was treated like crap doesn't mean they all suck. I have been daily driving my NA KA for 9 years with NO PROBLEMS other than routine maintenance. I'm sitting right at 160 whp, so long as you use quality parts and don't treat your 240 like a redheaded step-child.

[frreakyskater168]

if you want to go all motor on the ka, the best thing to do is add recessed top pistons with a larger bore, a slightly larger cam, header and full exhaust, remove all unnecessary components, and improve the driveline.

wow , just wow. My KA is bone stock internally ( I think ). My 1/4 mile is on the left. Car is actually faster now.

wow man ..wow..bent rods?..as in stock shot pingd rods?...bearings..as in budget bearings?...you dont have the first clue...who would rebuild a ka with stock parts for max N/A hp?..only a fool...seems to me you rebuilt with stock cra-p and screwd the timing up...man..just couse you fail at a N/A build..dosent mean that a turbo build is better..couse actually..there the same...you still rebuild new pistons/rods/cams/ect ect..so your point is mute..and your a fool.

Wow now this I would like to see... what mods DO you have if you don't mind my asking? what was your 60' and 1/8 time? Size tires?

[D-UNIT]

Honestly I lost the time slip. That was 3 and half years ago , but I'll never forget (most of) the numbers thou. The track was about to close for good and all I wanted to hit was 14.9xx sec. I pulled 15+ runs of fail. Missed it by 0.014 sec of "no 14s for you".

60 ft 1.98sec Toyo proxes T1S 205/50/15 @ 19psi stock alloys 1/8 ??.??sec @ 77mph1/4 15.014 @ 94.56mph

Parts I had at the time : Obviously Bolt Ons!!! haha j/k.

There is more , just can't remember all of my old set up.

[Canseri]

I have a DE and a E my SOHC will see a cam as soon as i get the mutha running

[24DSXY1]

check out treyz allmotor 240 vids on youtube-he does 14.8 and 14.7 while braking before the finish(he said cause he was bracket racing and he didn't wanna break-out)

he did it with just bolt-ons(stock cams) and the stock open diff!

[sav180]

je pistons make 11.0.1 pistons for the de and xcessive make intake mani's and itb set up for the ka along with sump oil pans adapters

[Ajax]

Sav- I can't see it very well, but is that an Xcessive manifold in your avatar? Do you have one? if so- NA or Turbo and how do you like it?

[lexcrob]

ok so ka24e pistons give ka24de 11:1 but nissan discontinued pistons...huh

1)where can i get some 11:1 ka24e pistons
2)is it letterally put that sucker on get some arp's / a tune and RUN IT????
3)if not ^ adj. cam gears needed for stock cams maybe some machine work needed

----i have searched and no def. answers at all how bout the FACTS how to do it what to do where to buy and pricing

----if i make 180,200hp what ever thats better than 136hp import tuner says ka makes with boltsons SUCK

---- im debating a rebuild and if it will work ill straight up do it shoot peen rods arp rod studs and rev it high ....probly wont make that much but i dont seee any budget NA ka's anywhere ....if there is please link it up!

ALL ive read when searching multiple forum is _it can be done it works makes like 200hp some guy???? is runnin it one guy for real 200hp for a piston swap its got to be insane hard like degree wheel and dial ind. on the valves .




.....ANYWAYS WHATS UP WITH IT maybe i cant find the 1990's forums that are gone forever and people think you can just search for em. this is gettin to be like a hondatech thread here-so-soin-so's runnin NICO is better than this!!!





i mean is it like throwin p30's into a lsvtec.....CAKE

[seang]

The natrurally aspirated KA forum goes back pretty far, get something to drink and start going through the old threads.

[lexcrob]

I dont know why that posted so many times?....

Anyways i grabbed somthing to drink nice cold beverage and started searchin around. I got nothin so beats me i guess aftermarket is the only option or ill just find some e pistons and try it. <- i would hate to be the guy that get the v to v and v to piston clearances and cc the chambers to get volume calc. compression ......yea im lazy ill just wait till someone posts up or i find that thread about it that dont exist.

[lexcrob]

In fact now that i looked into tuning or rom editing options for nissan.....yea jimwolf is a long drive from TN. Why cant it be like a honda 2 maps done.....vtec only switches in vtec.

sorry im just venting i guess ill give up and just boost like everyone else lately

[biggie]

Jim Wolf and others can be tuned by sending the ECU out and getting it back through mail, no need to drive there.

[seang]

Here are a few good threads:

ka24de-with-sr20-injectors-300zx-maf-ec ... 54896.html

whos-got-the-most-powerfull-na-ka-t226208.html

ajax-s-intake-manifold-t415340.html

[lexcrob]

I know you can get a send out tune but still its a sent out tune. Ive never personaly experienced them so i cant say much i had a buddy that got a phearable send out for his lsvtec with p30 pistons= it had a hole in the map or misfire at a specific rp where to much fuel.... it was a while back i though he was full of it

Well i guess ill end up tryin it out save it for another thread.

Since this is All motor thread and that normally requires a complete rebuild where can i get a good rebuild kit?

[lexcrob]

i there a guide/thread/link to how exactly to put sohc pistons in to dohc what has to be done what year is best ?

Ive got a spare motor torn apart found everything is good just needs refresh hone/rings/bearings- figured id give it a try

Id like to just throw in some pistons anyone make some for cheap? Maybe the nissan hardbody engines .....


Everyone says o yea just throw in sohc pistons but to my knowledge no ones done it and if they did they no speak of it...

[-RJ-]

I read that you can put the sohc pistons on dohc rods and the rings are the same as well, you just have to get tuned and run 93 octane or you will get a lot of ping. I really considered doing this too but my car being my daily I cant really afford for it to break down
