Sacrifices to the BOOST GODS!

[DammitBobby]

Maybe if we start making sacrifices to the BOOST GODS they will be good to us:) KAT forum has kind of been slow recently and I feel like we need a spark to get things going.

[Charlie240sxt]

What do you think we should sacrifice with all the blown motors latly you think that be good but fine i am on my way out to burn my car to the ground think that will help you guys??

[DammitBobby]

LMAO You may want to wait until we figure out what is neccesary!!

[DaRkSiDe]

how about you guys stop using a motor with over 100,000 miles on it and leaks oil out of every hole on the block that would be a start.

[wild_maxx]

who the **** is the noobie? not every ka-t is that ****ed up.

[DaRkSiDe]

newbie??? might be a newbie to the forums but it doesnt take a rocket secientist to figure out what to do and what not to do.

not buy cheap turbos.....buy a decent turbo. You made that dission the hard way. If every motor isnt like that why are you on number 3? Not tuned right? not enough fuel? to much boost? Detonation? you tell me what makes these motors blow?

same as taking any motor not intended for FI and bolting a "kit" onto it. You take a chance, expecially not knowing the history of the car or the motor on top of that.

But hey what do i know, im just a newbie....

[Chezedik]

Wow, a naysayer. And a newbie who's done it all. Around here we generally try to be supportive.

[240TweakerNewbee]

Please tell me I'm wrong about this but KA's with 100k miles or 2kmiles are not made with internals that can handle tubos. When you have pistons that are running 10.5:1 compression and you slam more air into that chamber you are taking a bad situation and making it worse for that piston, not to mention the different ways internals in a factory turbo motor as opposed to a N/A motor, IE; Forged pistons, rings, and rods. Anyone can put a turbo on a KA, but making it reliable is a whole other story and a ton of ca$h later. This is why (dare I say it) SR's ROCK!Sure I understand that there is no replacement for displacement but with cost to benifit ratio, I for one am willing to suffer the loss of .4ltrs of displacement for turbo'd reliability.

[DaRkSiDe]

never said i done it all. You call me a newbie and im not plain and simple.

Its common sense. You just cant go out and boost a motor and expect it to run like a top. Maintance before hand would be the key.

Supportive? Of what? I blew my third motor what am i doing wrong? How can you be supportive of that? Put the damn boost controler down back of the throttle and think. I mean honestly.

10.5:1 compression ratio on a stock ka? nope. its 9.5:1

the ka is very over built for a n/a engine. forged crank, strong rods, but weak pistons. there are many many other members that have been boosted for years and the engine is still good.

i'm boost for almost 3 years on stock internals with 123K on the odo now and been boosted for almost 50K miles running 9 psi for the first 2 years and 14.5 psi for the past 6 months. did a compression test and i'm still at 180 psi across all 4 cylinders

orion has been making 300whp on stock internal for years and he beatst he piss out of his car at the autox events

nissanfanatic is trapping 110mph on his bone stock internal KA that was boosted when the odo read more then 100K on it.

there are a crap load of boosted stock KA's thats been running reliable for years. my car is a daily driver for crying out loud.

LOL your a ****ing punk. my first motor was killed by a ground up bolt that somehow got into my motor.(accidents happen) second motor is still running fine, yes i was SOLD a cheap chinese knock off turbo claiming to be a garrett turbo, **** happens. Building third ka-t with forged rods and pistons. My fuel setup is fine, JWT ecu and SAFCII and LM1 wideband to tune it down. Don't join forums and start knockin the ka-t based on your opinion. Get some facts first that ka's are ****ty motors huh.

[SeVa-S13]

10.5 CR Stock KA's and forged piston stock SR's?

Pass whatever it is you're smoking.

[Florida240sx]

My motor had 178k when I first boosted.It blew at 180k.Up until that point it was perfectly.Actually my motor has blown.It has a spun rod bearing.Reason? I F^ installing injectors and fuel was in my oil and well when oil is thin like water .....it ain't good.Car still doesn't smoke. If i were to replace the rod bearings the thing will be good.But mine as well build it up. I had eveyr precaution taken but had one little mistake.And it bites you in the a$$

[fiznat]

never said i done it all. You call me a newbie and im not plain and simple.

You ARE a newbie to this forum, so I suggest you not make your first few posts so critical of the members who you really have not yet had a chance to meet.

We are all well aware of the risks involved when using cheap parts on older motors, so dont believe for one second that you are coming in here and telling us all something we dont already know. I dont appreciate your attitude at all, and while I realise that what youre saying is true and too often a problem with people new to turbocharging, it is NOT the correct way to introduce yourself to our group.

[HolyShiznit]

So much mis-information and haterade in one thread. Can we either lock this or ban the n00bs?

[Chezedik]

You can't ban them all, but I agree with Fiznat that this isn't the way to come in here.

[nissanfanatic]

SR pistons are CAST ALUMINUM! Basically the same thing as KA pistons...just with a lower compression ratio..

KA pistons are not weak... they just aren't beginner friendly aka do not allow a whole lot of mistakes...

lol not use engines with over 100k miles... At least we know how many miles are on our engines...

[1WheelWonder]

I think I will follow Darksides information and just up and ditch my perfectly running 200,000 mile 12psi KA-T.

[95 kat]

isnt that the truth. I know how my motor was run before. Some japanese dude ran the dog **** outta your motor and then wrapped it around a tree and now its a common case of one mans trash is another mans treasure. Do what you want but dont act like everyone on here is stupid as hell. You know anyone one with common sense can swap a motor out with the little sr swap bible. I swear monkeys could do it. The reason im going kat is because when you blow a ka how much down time do you have about 3-4 days depending on how much cash you have. Can be more or even less.

honestly I just believe that sr's are just a fad. If i was going to go through all the rouble I would go for a rb25or 26 even. It just seems more promising. Everyone has there on opinions though. Sometimes where you live affects this too. What you can get away with and cant get away with. Or funds too. Sometimes you try to see what you can build for cheaper. For instance I got my 95 from a friends x girlfriend for pay off. Only paid 1500 for it. Thats about as much if not less then that then you paid for a sr. I am on a budget here and just dont have enough free time to roam and look for parts. Its just whats easier for me.

Just be glad we dont all have honda's and evo's. Then everyones set-up would atleast be like someone elses and we they would all be boring.

[nissanfanatic]

eh...no matter how much anyones setup is like someone elses... if its fast, then its interesting...

I just don't like someone telling me I set my car up wrong and should have done this, or should have done that. Or hearing someone else do that to another person. No matter how ****ty someone's setup looks to me, I only give them advice in the nature of curing problems/prolonging the life of thier existing setup. Never "oh, thats a dumb idea, its worn out!! Should have done blah blah blah... " Hence why I don't go to the dragstrip very often...

[DaRkSiDe]

see that you said you wanted a spark in the KA-T threads and you got one.

I never ment to come across as a punk or a newbie or a F^ person. I hate to see threads where most of the guys dont understand what it is they are working with or dont even know how they work together.

Its how i am. I mean honestly if you can sit there and tell me that you havent had one concern about turboing the motor in its current state a week after buying and not giving one thought to do any kind of maintance then yes you blow that. Then when it does happen what is the first thing someone says???? Its the milage of the motor. Am i right or wrong.

As for the guy that called me i cant remeber what it was...........sorry you got burned i was making a point. You got the point that i was making.

I have a buddy with a turbo KA. He was smart enough to find one with low milage at a junk yard for a decent price. We knew the history of the car and got the motor. Turned around a week later and was slaping a snail on it. I in no shape or form raged on the KA or brought up the fact of a SR.

I will be doing a DOHC KAT so why would i knock the motor never did.

[240TweakerNewbee]

KA is a great motor, its never let me down in the 266k miles I put on it. I just didnt see any hope for redoing it for performance "the right way" without dumping 2x the money as compared to just doing a SR swap. Its true the only real argument here is money, but the KA looses that argument, I spent 3 months doing research about it. Ive got tons of respect for anyone that goes the KA route, its more expensive (if done right) and its more work, also Im sure the extra .4ltrs of displacement will in the long run make a bit more power (displacement is the limit of my respect if your going to say anything more than that). But is it substantial enough to offset the cost?... I dont think so. Seriously give me a real argument here besides money for why people who are obviously into performance would even bother with such small displacement motors in the first place. I mean for what you spend to get real hp out of a KA or SR you could have gone domestic (Mustang or Camero) and got and easy 500ponies plus saved yourself a mint. I need someone to explain to me why people try to get 250hp per liter out of a 2-2.6litr motor in the first place, on top of which has its peak hp and torque spiked between 5k and 6k rpm's (which is hardly practical for real driving). Also how they expect it to be reliable next to a large domestic motor that only has to push 100 or 80hp per liter to get the same HP (LS-1 retails for $3400 spankin new) at much lower RPM's with a much, much flatter tq/hp curve.

If your pissed at this point I'm with you, these are all valid arguments that are being thrown in my face by my boss who is a sport car fanatic, and he sits in my office slamming me with all this crap all week long. Sorry to unload all this but I feel like someone here could help me make an Intelligent argument for why we bother with these small displacement motors.

Don't say Im threadjacking because the discussion here is Boosting a KA which to me means adding turbo performance to a KA (2.4ltr small displacement japanese motor). Im simply asking; for the price to benifit ratio... why?Not to say that its wrong or right, just why, and remember I'm already your blood brother. Ive spent many hours and much money on my beloved 240sx, I would just like to see if I can find some reasons I havn't thought of.

[DammitBobby]

Actually I created this thread as a joke not for thread bashing.

Originally I owned a 69 MachI when I was 18. So when I started to seriously looking at buying another project car I kept trying to find a mustang. I couldn`t find one reasonably priced that wasn`t a POS. So while searching somebody I knew asked me if I wanted to look at his car and handed me the keys to a 91 240SX with 152k on it. I was suprised how much room was in the engine compartment. He had 3500 into it and I bought it for 2k. About 8k less then any of the mustangs I was looking at. I fixed general stuff to it and then installed a basic turbo kit. At that point I could beat a 94 or lower GT Mustang. Now that I have a stock rebuilt motor and upgraded injectors and JWT ECU I will see how well the V8s run against me. Still under my 10k budget.

The main reason I am doing it because there is no other car around here that is the same as mine. If you get a camaro or mustang you can see them all day long but you wont see many KAT`s or 240`s for that matter. The other reason, it is so much fun beating a V8:)

[fabio420]

let's see, intelligent reasons?1) Weight distrivution. A 240sx weighs a lot less than a mustang. So does a KA compared to a 5 liter. So, less horsepower takes u further.2) Nissan makes the best cars around (chassis + drivetrain)3)Gas consumption can be held down (if u don't boost), unlike a v8 that's always guzzling4)To tell someone that their "BEEFY" V8 just got beat by half the amount of cylindersand as someone here has put as their signature: "Domestic are like tampoons, every p@#*y has one"

[Charlie240sxt]

slos13 had over 215k when he just took it out to replace with a newer motor and he was up to 14psi and he was tring to blow it

[fiznat]

Ah, V8 versus turbo I4. At least its a better argument than KA vs. SR.

Power to weight ratio is the resaon I chose to do a turbo I4. I've driven a number of big power v8 cars, and I have to say it is a completely different experience. True, the torque off the line is pretty crazy, but driving around town I felt like alot of those cars couldnt get out of their own way. The turbo 240 is VERY, VERY fast (if you do it right), but the plus side is that it can actually turn- its not a gigantic boat (as a lot of the v8 cars felt like).

If you want to talk about power per cyl, a high power 240 (400+ at the wheels) is no different than a 800-900hp V8 car, which is equally common. The difference is, we can be just as fast with half the power cause of our weight.

[k6kicker]

And its threads like this (and the seeming billions of 15 year olds) that keep me from being a regular here......

[Charlie240sxt]

^ Then you know where the door is no ones stoping ya JK

I drove my moms 00 6 speed SS and its fast but seems alot slower then 230whp sr i driven and then the 320whp 240 i drove was crazy fast
