I havent been on here for too long of a time but i have seen so many people posting debates over building a KA-t or swaping in an sr, ca, rb and so on. I think the problem with most people is that they really cant think for themselves. I mean ivan, duy and all them the reason they are building the ka's arent because someone on some thread told them to do so because its better than the sr or so on. They are doing it because they want to be different. If this is your first time really working on a car its kinda pointless to get on here and ask people which is better because you yourself dont even know if you could build or swap something with your level of knowledge. Like ive seen countless amount of times when people ask which is better they usually get told to do research. That is the truest (i know its not a word) statement i have ever heard. I grew up around cars and i originally started out as a chevy guy, but wanting to be different i decided to go import and build a honda. I like alot of people got the b16 screwd in the ass set up. From there i learned that jumping on the band wagon can sometimes be bad. And that it would be better for me to just research what i want to do and how i want to do it and what i felt comfortable doing. For all you newbies out there and other people, its ok to ask questions about motors or stuff like that but dont come on here and ask which is better. Its pointless. I mean damn think for yourself once in a while and decide what you want to do with your own brain. I mean damn if you wanna build twin cylinder lawn mower engine for your 240 then do so and do it well and take pride in what you did. Well i hope alot of you people read this and take heed in what i am saying because without people thinking for them selves and wanting to be different then we would probably have never gotten to where we are in the automobile industry today.

well i finnally made up my mind on everything, i got to pick up my ka24de today from a friend that i helped do an sr20 swap, ive already disassambled everything and the block and the head is going to the machine shop tommarrow for all the maching work. This is going to be my set up
Ka24de- Ported and polished head, ferrea Valves, springs, retainers, 392/280 382/270 cams, arp head bolts, boost designs port matched header, custom build intake manifold, squared and decked block honed and bored .20 over weisco or supertech pistons, pauter rods, toga main and rod bearings, micropolished and knife edged crank (everything balanced and blueprinted), cometic head gasket, t3/t4 airpump (lol, for now) tial 38 mm wastegate, blitz bov, greddy ic, a friend is going to make my plumbing, rc 52/lb injectors, boost designs fuel rail (or i might get one made) z32 maf, greddy emanage, walbro 255 pump, koyo radiator twin fans, boost designs custom exhaust, and a few other things. hopefully the machine shop can get their part of the work done pretty quick then i can have it done in 3 or 4 weeks, im slow cause i work during the day lol
ill keep you posted

i havent really priced anything yet but i do have my own business and tax number so i will get it all wholesale if they allow but im guessing somewhere around 4-6 but thats fine this is my next project car that im building. I just sold my last project which was an 02 subaru wrx, ive also built a civic, eclipse, a 94 chevy shortwide truck with a stroked lt1, an rx7 for a friend. so i figured id try a nissan now.

well if i was not going to run high boost then 9-1 is not that bad but i plan on running up near 20-22 so i think im going 8.5-1. I think alot of people use the 9-1 because they dont run very high boost and thus a 9-1 is actually pretty good....but if you ran high boost on that the rods would not be able to take it because of the high cylinder pressures.

the internals should be ok to 9lbs shouldn't they? i am going turbo by the end of the year (saving up for a house, too, and that is a priority), and i am planning on running about 7psi daily. the motor has been rebuilt, and i don't think the stock internals at 9.5:1 should have trouble with that level of boost. just have to watch for pinging, and not buy crappy gas.......
your setup sounds like it will be pretty nice, i have to say.

running that compression at 7 psi will be just fine. It will actually make more power at that level than if you ran 8.5-1. Its kinda like taking two different sizes of glasses and filling them with the same amout of water, the smaller one of course will look more full then the larger one right. I think there was an article about this in a magazine ( i cant remember which one) it had to do with an srt-4 and a svt focus. The focus was at 10 psi i belive ( may be wrong) and the srt 4 was like 14. Well the focus made more power being a 2.0 over the srt 4 being a 2.4. The svt was running lower boost but was making more power because the compression was higher than the srt-4. But to conclude what you were asking yes that compression will do just fine...just make sure all your bearings are good and your head gasket is good. Which is pretty much a need be on any motor i think.

If you're going to stay at a low boost level, you don't need reduced compression. You can actually use increased compression if you're going to stay low. The s15 did that, which is why it made so much more horsepower in stock form.

hooray for this thread. As if no one else said it. I love it. Its true. Don't let yourself fall into another meaningless trend. Being unique is something that will never fade in time. Fallow your mind and heart, and show the world why you got your car in the first place. You've got my respect. Do what you love. Keep it real. . . lol. - Nicholas

·im probably one of the 'newbies' here but have been around my own 240 for about a year now, and with cars period for over ten. i wanted to do so much with an sr20 swap and all of the goodies that can go into them, but then i had an accident with my KA tranny one day and it basically made me think alot about things. i was driving down my street switching from 3rd to 4th, and as soon as i hit the clutch pedal to shift and i got into neutral, the transmission basically exploded. turns out, when i got the tranny out and inspected, the guy i had bought it from before me hadnt torqued the flywheel bolts down right and caused my crankshaft to spin my cluth into a frenzy. ate up half the housing(most of it was in the street after the "explosion"), ruined the crank, grinded 3 flywheel bolts, and i couldve had my leg severed by the flywheel(that one flywheel bolt left saved me :tears ) . it was a mess for the 500 bux i got the car for. now, i dropped the sr idea and am now going with a KA. i mean that extra .4 liters will help boost at lower rpms, and it will also spool up faster. so i think the KA, for me, will be better. right now my head is in the machine shop as well. i bought a new crank, short block with rods(pistons and rings still in great cond.), tranny housing, ACT cluth set, nismo slave cylinder & stainless braided cluth line, and i just recently found a custom intake and exhaust. the KA should now be close to, or over the 200HP mark, n/a. i think in the long run, the KA's bigger displacement will help my huge power output i plan on getting out of my engine.

Can we please use paragraphs, that rant was so hard to read, i didnt get past the first line.
With that said ill just base my reply on the thread title.
You cant end this debate because someone, someday is gonna come on here, read all the great things about KA-T's and SR-T's and they'll wanna know which is better. Both sides think they own the better of the 2 setups and the only way for this person to make a well calculated, thought out and weighed decision is to have all the facts layed out infront of them for them to choose.
If you're choosing a motor based on a feeling you got from watching movies and from hearing people talk, you shouldnt be doing anything with your car. Denying someone the right to post a debate thread is ignorant, there is a better motor in every situation. We need KA vs SR threads to keep the debate alive and real.
I would be pissed if i didnt know anything about s13's and i came here asking which motor was better and everyone told me, "Make your own decision, we wont tell you which is better or why we think so because everyone is an individual" blah blah blah.
If something is good for you, its probably good for most other people like you. Most of us are below the age of 25, and none of us have cash to burn, money plays a huge role in our motor debates.
I just watched my buddie run his SOHC-T at the track tonight and it supports my KA-T love more than before. 89 240sx, original motor, 200K's, 10psi boost setup on a T28, less than $2000 invested in parts and it pulls low 14's on streets all night. Bone stock SOHC with bolt on kit - how can you argue!?

The human drive to compete will always keep every arguement alive.
With that said, your cams look quite extreme. Are you sure the overlap isn't too large?

just read this lol i posted a topic on what i should do with my engine because i dont know much bout nissan i know mitsubishi so i figured i'd get some quick answers and opinions before i did anything.
but yea i agree with it even though i did it
good post.

I never understood this perspective on building a car. This kind of view makes your car into a stupid fashion statement. It's no different then rich valley girls with expensive purses, guys just use cars. People have this concept of possesions-as-identity that is weird. Any car I own will never be an extension of myself as a person or my "individuality". It's just a car...... :12dunnoDef_Jam said:
I always thought you built a car for yourself. You build it as a toy/tool to do what you want it to while you're driving it. If you go out of your way avoiding proven paths of modification, you're probably wasting energy and not getting the best bang for your $ performance wise. Personally I'm all about results for as little $ as possible, but I guess thats cause I don't really feel a need to ever be hot-shit do-it-yourselfer who was the first to ever do so-and-so....I'm a results oriented guy I guess.
I'm sure some of it had to do with the SVT's higher compression, but I would bet that's not the only reason it made more power at 4 less psi and .4 less liters of displacement....(I'm betting that SVT had a fat ass turbo compared to the stock srt4's).jonathan rubio said:
