Scared of the ka-t

[UncleBen]

I'm doing my best to research and read alot, which I have been doing quite abit of. Its helping...

[xxtrizz]

Not to be like promoting anything but WDracing is comin out wit a kit ya heard? ANyways from what I can tell its pretty much set up for you to set it any which way you want and protect against detonation wiht the retard.

SO like you could save up for that instead since its gonna take you a bit to save up.

Honestly I jsut started saving I make pretty darn good money but damn man all I have is like 1g saved up in 3 weeks and im so impatient and I wanna beat people up cause im not sure what to buy blah blah. But I realize its gonna take longer than 1 month to have a boosted KA. Im just jealous caus emy bro gots a 3000gt and is smokin my ***.

jUST BUILD YOUR ENGINE FIRST BEFORE IF YOU THINK YOUR GONNA HAVE TORUBLE.. YA KNOW? If you plan on running ANYTHING voer 7 psi, build it... Cause if you build you know your **** isn't gonna break as easily and your **** is new.... anyway..

[Structure240sx]

just go and spend an extra $2k...

if the engine is detanating enough at 7psi to blow it stock then anything over 7psi built and its going to blow. we all know that with decent tunning alot of power can be made on a stock ka.

no offense buddy, once you have a kat then you can talk, ha

[UncleBen]

lol

I am actually thinking about picking up a long block from a friend of mine, who has one just laying around his garage. I might get it, then slowly but surely start to build it, just because I have that much access to it. Only problem, I dont have anywhere to put the motor while it is being built. I have the know how to build it all (not me, a friend knows everything) so all I need is money, time, and a garage.

[xxtrizz]

Yeah the rebuild is the way to go man. Ensures you against anything failing. Well to an extent Im gonna do a rebuild myself. Hopefully afterwards it will be smoking some hardcore ferraris and ****s.

[Structure240sx]

theres no reason to build a block unless you plan on going for high boost and start invest alot of money into it. is the engine your friend has complete/runable (new word maybe)? if so jsut keep that as a spare if anything was to happen which it wont at 7psi with minor tunning

[Structure240sx]

hey klattr1, how about you testify about how quick a build block can go? sorry to bring back bad memories but its more important to have good tunning than forged internals

[UncleBen]

If I got the long block from him and I built it, then of course I would go high boost, just because I could. Tuning would obviously be in the works with it as well, but yea it would be a high boost motor if I built it. The motor used to be a ka-t motor actually but #3 fried a ring (apparently, nothing else seems to be wrong). Compression test of the motor when it was still in the car showed good numbers accross the board, except for #3 which was like 60psi. So that motor was pulled. The head and everything seems to be good.

Or, like you say, I could just run 7lbs and be done with it. I need to do a timing chain job on my KA, which wont be that big of a deal if I ever decide to do it. That would be the only 'rebuild' type thing this motor would see. It runs well; synthetic every 3500miles approx., not driven hard, etc. It should handle 7lbs nicely. Now all I need to do is save some money *sighs*

[Structure240sx]

good plan, save money

BADA BING

[UncleBen]

Thanks GEO

[xxtrizz]

Well any SOHC engine I would definitly rebuild no matter what because of the ringland issue. But i fyou got a DOHC then no worries. But yeah I would rebuild and plan on running hardcore boost or just being able to have that option. So that way I can be like you wanna rac me? ok whats your HP? give me 1 hour let m tune and then well race hahha

[Structure240sx]

so now dohc ka's dont have ring land issues unlike sohc? thanks for telling me this great news. wonder why my ring lands went in my stock engine, or maybe it was from horrible tunning or lack there of

[TrunkMonkey]

the sohc and dohc piston ring lands are identical. as a matter of fact, the only real difference between the two pistons is the dish volume.

[GEO]

ohhhhhh SNAP

[xxtrizz]

Geo dont post unless its productive your little tiny posts of

"OH geez" "SNap crackle pop"

and what have you, help this non whatsoever.

Its from my understanding that the ringlands for the Sohc are different than the Dohc.

Here let me quote sds efi systems:

Quote »This engine was never detonated so the damage was somewhat surprising however, the short compression height on this engine means that the ring lands are quite narrow so not so strong.[/quote]

So from this I can infer that the compression difference is going to make for different rings. Just putting that out there for feedback. Honestly i dont know why your ringlands broke but coulda been lack of tuning? Who knows maybe they were ready to go anyways (IE mileage or lack of previous engine care)

[Structure240sx]

they were talking about the sohc correct? did they have any experince with the dohc? we have all just been proved by spracing that the dohc can make plenty of power when tuned right. tunning is more important than how a motor is built i believe

[xxtrizz]

I totally concure with that remark. Now only if we could get the sr20det crew to realize this notion then we would have a larger following :P hahaha.

Yeah I realize that tuning is way more important hell that AEM EMS looks better everyday.

[GEO]

I am just telling him, low boost or High boost, replacing the internals kinders to him having LESS problems...

[TrunkMonkey]

that's not even remotely close to being true.

-demetrius

[GEO]

what? Its just like anything.. If you buy a bike with a rusted section of the frame....and you replace it with a new bar.. you have MORE confidnece that the bike won;t sh it out on you and break.

[veilside180sx]

i happen to ride a lot of bikes, i see rust, out with the whole frame!=)

[GEO]

I am just using that analogy.

[WDRacing]

With decent tuning the motor will run fine under a decent amount of boost. If your goong for more then 15lbs of boost you should upgrade pistons, but the rest can stay.

For the record, if your going to swap out any internals, do yourself a favor and port your head. It's so easy to do yourself, it just doesn't make sense not to. I'm not saying you should go hogging out the intake runner, just smooth out the factory defects and gasket match the head/intake and exhaust. Smooth and polish up the bowl as well. You don't even need to remove the valves if you don't want to. Just use caution not to damage them.
