I cant believe you guys are still crying about this. Please keep typing about this . I want to hear actually i dont care .....

that just made you sound like a little kid. ( little kid says he won a race) no you didnt! yes i did !(guy) no you didnt i saw you lose! little kid: so i dont care...

[nelson8708]

vinnie you like to just type alot so everyone thinks you know what your talking about ,but square decking is not used to even symmetrical lift ,you sir are an idiot. Do you work at an engine machine shop probably not seeing how your a contractor. I do and we build race engines all day long for boats ,circle track cars; and we build 4 cylinder race motors. the only reason to square deck a block is to gain power by increasing the cr and dumbass why would you do anything to a cracked block but throw it away that shows how ignorate you really are. I didnt post this to have some contractor come on and think he knows everything ,go clean my driveway then repaint my house you ****ing *****.

STFU and go back down stairs into your parents basement....aka the engine shop

[DjPantsSpecR]

wow..... i build 4 cyl race motors all day and i deck them to gain compression..... screw using pistons, i deck it to 15:1 compression....

this is THE BIGGEST joke ive read on NICO for some time.

you need to research for at least another hour or two before you go claiming you can make over 300 crank horse with basically bolt-ons.

and if you do believe that, youve obviously been had kiddo.

[SR20Essex]

This would be somewhere in the vicinity of 330hp at the crank (17% drivetrain loss) which puts this amazing engine at over 130 hp per liter...I'm sorry man, but I still don't believe, not that my opinion should matter to you anyway.

It can be done... I have a N/A motorcycle that puts out 145hp stock; it’s carbureted (individual throttle bodies), 5 valves per cylinder, and is 1000cc in displacement. Runs on pump 91oct.

[DjPantsSpecR]

well yeah.... think S2000.

this motor and motorcycle motors both make those large horsepower figures by reving the **** out of the motor.

my .15 cubic inch RC car motor makes .9whp. it also revs over 30k.

obviously, this isnt how this KA is making power, which makes it look so fake.

and as long as we're talking about motorcycle motors an FSAE motor can only be a maximum of 600cc's. it also must breathe through a restrictor that is 20mm or 19mm based on fuel (100 or e85). the restrictor makes max power at a very conservative 90 horse. thats 150 hp/liter.

so obviously, it happens all day every day, but these are motors that rev ridiculously to make power (tq x rpm /5252). This KA somehow miraculously makes twice as muhc low end torque and twice as much top end? short of forced induction or nitrous....

no, didnt happen.

[Bigvinnie]

wow..... i build 4 cyl race motors all day and i deck them to gain compression..... screw using pistons, i deck it to 15:1 compression....

How much can you deck a KA block before the piston makes contact with valves, or roof of the head??? IMO little to none, I mean in reality on a KA we are talking very small fractions. I see more DESTROKED 4 bangers get a square deck job than an engine that is still using OEM parts. I have seen clover leaf welded heads on a KA24de make about a 14:1 CR, I'm pretty shure GUDE is the company that does the work....I've also seen clover leaf welded head on KAE's, NAPSZ, and L series making between 14:1, 15:1 CR's, square decking could probably add a tad bit more CR probably like a point or 2, but nothing that would significantly increase a tremendous amount of power. I mean if you also look at money over effeciency you can get super tech pistons, or wiseco's for cheaper than decking the block, and still yield a higher CR than you could with decking alone.

So you would rather deck a block that doesn't need it over these bad boys?? These are wiseco pistons in 10.5:1 and 14.1:1... As you can also see there won't be any significant lifting cams for either of these 2 for valve clearance.

Where is a picture of the engine? Shows us something. If you truely have found the secret to the KA then why are oyu being an idiot about it. There is many many people that would drive to your shop to have the work done. Object of bragging about it when you are part of the shop is to bring business.... You going to bring your car to the shop that has a stock honda out front? or a race built 240 that runs 11's N/A???

[DjPantsSpecR]

vinnie i think you got my sarcasm, but thank you for those sex-licious pictures anyways.

i lsot all my good pictures and info when my computer crashed, including all of the pictures that deviousKA posted of the Rebello dry-sump KAs in the baja trucks.

either way, those pistons would always scare me with cam gears or aftermarket cams. i cant wait to get a hold of a set.

[whiterps13]

Run and hide. Videos or ban.

[spank044]

Hey Sliders i wanna see some pics too.

YOUR FULL OF $HIT and Bigvinnie is right. I dont say much dude, but show up or get the F@#% out.

Can someone BAN his A$$!

[Bigvinnie]

vinnie i think you got my sarcasm, but thank you for those sex-licious pictures anyways.

Actually kinda funny. I really didn't get your sarcasm until I edited the post the second time with the pics of the pistons... My bad man.LOL I had to reread it, I have short term memory issues..........Sometimes I read over something twice before I get the joke....LOL

[nismofly]

here you guy go, proof that youre full of crap. i dont care what you did to the motor, NA it is IMPOSSIBLE to eek 270hp at only 9.5 to 1 comp.....period, the rest of your mods are irrelivent and you need to grow up and not get all butthurt when you start making up stuff and people call you out for it. This is nico, and we HELP each other, you dont wanna do that then go join zillvia of FA....

heres the text from an eailer post where you leak the specs of your super uber secret KA project.....mild street cam+9.5 to1=BS

zerothread?id=126913

lol which he just happened to conveniently delete today

[nismofly]

i will say this...GT3 spec NA KA-E's make around these kind of numbers

however, theyre doing so with 15:1 compression, cam durations over 300, and turning 9, sometimes close to 10,000 rpms to do so

you laugh because we dont believe you, but if it was true youd have no problem proving it

[pregmantis]

nismofly, I dont know what a gt3 engine is but the kae's can make this kind of power without running 15/1 compression. I think they can do it with somewhere round 12-13/1 and some dont need to rev to 9g.

[superDorifto]

We dont even have to get into the specs of how to make that much power on a KA. throw enough money at any motor, and you can get it to do pretty much anything. I guess the most important thing that every car enthuseist learns to is that speed costs money...there are no short cuts. There is no magic combination of bolt on parts to turn an ordinary production motor into a race motor (well turbos can help i guess). And that is why respect is given when you reach that level. You know what....of all the people ive ever met that have been putting serious power out of anything, be it a Mustang, Corvette, or even a Civic, never once have they acted like a know it all deuch. You give respect you get respect....you talk ****, then your prolly full of too.

the ones im talking about are for scca gt3...the ones made by rebello and such

i was just guessing at specs...but i know they turn revs waaaay up there, any 4 cylinder making that kind of power NA has to

[nismofly]

btw, he doesnt even live in jersey, dont let him tell you he just moved there

i may even call the shop today to find out where that dyno graph came from

[neverlift]

how about that sweep yesterday go NISSAN 123

A fully counterweighed crank, with titanium valve train internals can easily rev to 9000~10,000 RPM. I believe corr actually makes a few of these for there trucks as well. It uses a NISMO crank that was designed by ED PINK. I called NISMO and they sell a whole internal assembly for about $8000 it uses all new internals with the crank, which means new rods and pistons with different rod/stroke ratio for less friction. The stretched power band allows these engines to max out at about 330WHP. I'm not to shure on the regulations of the GT3 class engines but I believe that they can only use a modified OEM crank, rods, and piston assembly. They can get rev happy to about 8000RPM redline and max out in power upto 280WHP. Of coarse this means it needs an additional power band and redline to require additional power.There was a GT3 being sold in the craigslist bayarea for around $9000 a few months back in the add it claimed to have a 13.1:1 CR

[naed240sx]

God this thread is so retarded. The OP is blabbering a bunch of BS, and his defensiveness is more than enough to prove that he is lying.

Here is a dyno of about what you would expect to see out of a well built high comp KA with effectively bolt ons like the OP. Much more can be expected out of a full race motor, but it is obvious that the OP's motor is not.

[Bigvinnie]

Damn that is a freakishly weird power band. Where the HP drops for a tad at 4.5RPM the torque band blows up like a balloon... That car must chirp in every gear in the 1/4 mile.. Thats cool.

[naed240sx]

Most dyno's would look like that if they didn't have very much smoothing done to them. Most dyno's that you see have been smoothed over digitally to remove the bumps. The drop and quick climb is simply a result of small accuracy errors with the dyno. The actual power production of his car is much smoother than it appears on the dyno.

[sensibleS13driver]

Race engines are usually like that, slow build up of power, then a surge and a sharp drop off.

[pregmantis]

I didnt know that the sohc could reach bout 330whp, the last i heard the dohc was reaching about 350chp. I would love to build a dohc for a change.

SOHC's and DOHC's are almost Identical.I mean there are minor differences. Like the SOHC head only having one exhaust valve per cylinder while, the DOHC has two.DOHC blocks have oil squirters while the SOHC's do not.DOHC's of coarse have a pentroof head while the SOHC's use a hemispherical design.The one thing missed is that SOHC heads you can port the crap out of them, while the DOHC head is limited. SOHC heads can also use a solid lifter assembly with adjustable valve lash, the only thing you can do to DOHc's is shim the buckets.Alot of the Datsun 510 guy's that I talk to that are 50 years and older use SOHC's for its simplicity, and major tuning atributes. They even claim that the one exhaust valve per exhaust cylinder is much better for midrange power (something to do with scavaging and splitting pulses). Some people actually believe the SOHC is more dominant in making more power than the DOHC's. But I don't want to open up thatr can of worms, it is a controversy that will never end. I myself am a DOHC guy.

wtf is there to "believe"

every engine is different, it either makes more than another or it doesnt

[C-Kwik]

working on uploading the vid but heres the dyno sheet...

Hmm? Not only do you point out the wrong figure for HP as someone mentioned, you're not even using the peak torque or HP figure. You can at least learn to read a dyno chart. And looking at this dyno chart I highly suspect it to be a turbo motor. The torque ramp up appears very similar to many turbo 4's I've seen. I doubt a cammed up ported KA can have such a borad torque curve. And it would be highly improbable to get even 203 HP NA at 4000 RPM as that dyno implies. Nismofly nailed it on the head on this one. 300 HP NA KA's are running some 8000+ RPM. 203 HP at 4000 RPM would require a lot of displacement to achieve. Higher compression, cams and headwork is going to have a very difficult time trying to reach that kind of number without forced induction or NOS. Perhaps if you dyno it in some cave that's some 10,000 feet below sea level....

[pregmantis]

yeah, I know about the differences(have both blocks) I just didnt know the sohc was makin that much power(330whp) last I heard, they were somewhere round 320chp. I really want to build a dohc but they may be limited on vavle lift whereas my sohc wit rockers puts about .585 lift. althoug the biggervalves and ports may make up for this I really dont know. I like the combustion chmber disign better for the dohc. im thinking of doin the dohc with sohc pistons(high comp oem whichever ones they are) and off the shelf cams bccrowers 272durat. and maybe...... a lightened crank. yeah right! maybe in about 5yrs when I get a job.

I noticed something about that dyno. For every ones information, it is very similar to that of a naturally aspirated 2005 ford mustang V8.

[pregmantis]

I was thinking the same thing about the dyno, I know nothing about dyno's but that surel looks like alot of hp for such little rpm.
