Mr.Clerc

Whats going on guys, just a general question for my s13 coupe. I dont want to have to deal with turbos because i know more about older cars and pistons, valves and mainly just motor shit. What would be the best all motor motor i can work and put in my coupe? Just took the tranny out to put a better one in and want to actually start up my build. My car has a KA24DE fron an s14, advice is appreciated!!!

GroundPerformance

If E85 is Available the area. High Compression is the way to go..

If you want to keep it nissan I would go with a SR24VE build, they have been proven to make 300+ whp on 93.

Mcpot132

Anybody have any input on this type of motor??? Sounds interesting

KiLLeR2001

Go with the 350z engine, VQ35.

Ls motor. Cam, header, intake, and tune and you have a beast.

Mr.Clerc

One of my original plans was to go ls but i dont know if i have the money with how much the mounts will cost along with engine and trans, but if i get a good deal i definitely wanna go ls. But on the other hand i wouldnt mind staying nissan, and i've read a million and one bad things about jdmenginedepot.com and all those sites, so where could one find a good nissan motor?

shoguner

If you don't have that much money, I don't sugest a N/A build. They can be alot more than a simple turbo set up.


but.. If i was going N/A Id do a vq35 high comp. Or a 1uz.

In a nutshell, you probably don't have the money to make any of your ricer dreams come true. This is the reality that people can't seem to face when they think that a car is some kind of return investment. Once they make the realization that they can't afford to make the version of their car they hoped and dreamed for even slapping every fake part to make up for the slack of their budget on it. doing a couple of shit events and realizing you need to move on with life and grow up.

You'll quickly realize that the people replying to this thread with advice have not made the jumps with their builds or projects their suggesting because they too have realized they don't have the money to go through with half of the shit they post on these forums. And the few that do add up the stresses of spending the money vs the fun they're having with the car and silently disappear from here just like you will until we get the next wave of people who just bought a 240, want to get an fd license, or be the next senna.

And the few who are actually doing what they post on the forums are still building their cars, will never finish building their cars, and even if it seems done there is always more to do.

In the end it depends on where you're sitting in life.

That's pretty much the best answer you're going to get in this thread.

I can tell if you can't afford an LSX swap which will run 10 grand for everything to get it running out the door, anyone who tells you otherwise hasn't done it or has an LSX swap sitting around uninstalled because they're waiting for more parts to get it working. OR CAME UP.

I can tell you won't be able to afford any nissan v6 swap because those run around 7-8k for everything and not a lot of people do them, very few and you're not going to be able to take the car to someone and have them press a magic button to make everything easy for you and if you do find them you can't afford their time.

If you don't want to bother with a 2500-6000 dollar sr20 swap with a turbo you can always just keep the car KA and enjoy all of the natural abilities of that motor it has to offer and focus on making the car nicer in other areas.

Making power, sustaining that power, and maintaining that power all cost a lot of money.

And when people post "what should I get, but I don't think I can afford this" then the thread stops right fucking there and this should be quoted in EVERY thread someone posts about what should they do to their new car while working extra hours at the dairy queen thinking that they're going to have a team burst car with 6 months of paychecks and tons of free labor from awesome friends.

Because that's not reality.

Agreed on everything you posted.

Still, sometimes it is nice to dream a bit

I have "somewhat finished" my S13, after something like 4 or 5 years of work. And my goal was quite simple; no engine rebuild nor swap, circa 300HP (my car came with a CA18DET as it is a european one, so thats a basic "stage 3" design running e85) and a chassis that can handle it.

And it really feels good now. But it frustrated me for 4 years, working on it every week, breaking things, learning and so on.

The thing is, no stock car feels like that. Not even porsches i tried. And i cant afford them anyway.

It runs and i am quite happy with it
Still you are right, it is unfinished. I need to glue the spoiler, change some bushes, find faulty couplers that sometimes leak, and so on.

I know it will never be finished. And it probably will end its life in some tyre walls on a track. When that happens ... i will get/build a true race car, because i like that, and because i acquired some skills when buliding the S13. Oh, and because i know how much its costs, and how much money i have to spend. That is a very important thing

Mr.Clerc

Again everyone is entitled to their opinion and yes that is reality. But the reality for me is I work my ass off every day for 11 hours weed whacking at 17 years old. When I Want to do something I get it done or i try my hardest and dont give up. And yes thats what everyone who has been around my car is saying "Oh you'll never get it done, your a fronter ect." blah blah blah I know what my abilities are and how to use them so when I say there will be an LS in my car....there will be an LS in my car. Believe me or not, hater or realest thanks for sharing man.

Croustibat

Ok i am going to try to say it another way.

As you say, you are working every day for 11h and not getting a lot of money for that.

Why dont you just wait until you get enough money per month to do it without having to sell an arm and a leg, and spend your hard earned cash on something else ? Chances are that in a couple years, you will earn in a week what you now earn in a couple of months. And when you will think back about it, you'd think "i was stupid to use all my money on a stupid car that needed even more money to just run".

You are 17, have fun with your car in the current state, get tyres and chassis elements to drive the crap out of it and have an overall fun in your life.

When you hit 20 and get money in an easier way, make the swap. What is the point in spending maybe 1 year worth of hard work on an engine, when a couple of years later it will just be a 2 month bill ?

Better enjoy the fun of being young while you can. Because it does not last.

How much you think i could get a VQ with a tranny for?

SCRmotorsports

how much power do you want? ive seen the kits for KA's that make 250hp with stock injectors and ecu for around $1,500 i think. upgrade your fuel system and get a tune bam youl have a fun little car.

Mr.Clerc

99% sure now im gunna build the KA thats already in the car, its a strong motor never drifted so i might throw money into doing forged pistons camshaft valves bigger injectors. I already ordered an N1 exhaust coming next weekend, and have a walbro fuel pump to install. I think i'd be happy with a set up like that for a little bit.... does that seem like it be a reasonable set up with a decent amount of power????

Croustibat

Reasonable yet.
Decent amount of power, no.

KA is a truck engine, nissan fitted it for the US market because you guys tend to drive for a lot of miles, and they needed reliability which could not be attained with a turbo CA or SR. Dont expect power from this engine, unless (yes) you turbocharge it.

S14DB

The only Vehicle the KA was put in before the 240sx was a Minivan in Japan. There were several cars it was put in before it ended up in trucks.

It was put in the 240sx because the CA18/SR20DET made more power than the NA 300zx and Nissan USA did not want it to compete with it. The CA18/SR20DE was thought to not be peppy enough for the US.

If your statements were true why did they bring the Z31 over with the turbo motor?

The KA's head flows horribly and the long stroke make it less than ideal for a NA build.

If you know about old piston motors. The LS* series would be ideal. Push Rods and all.

thank you. i cant stand it when people call it a "truck" motor. it didnt start life that way.

GripTerror

VQ v6 or LS v8

The VQ sounds WICKED if done right, can be made very responsive but will not come close to any LS variation power wise... the chevy small blocks are also very compact and fit ridiculously in any engine bay...

1uz sounds great but makes shit for power.

LS v8 if done right would ultimately reap the most benefit.

VQ would be something on more of a budget but STILL will end up costing tons...

eek

NO replacement for displacement. Can't go wrong with any LS variant. I personally stay away from the VQ swaps since all the ones I have seen have the oil pan sit really low. Plus you can't beat the sound of a nice hot cam V8.

Feast Japan

Having been in the NA scene with my S14 for awhile, I would say go the SR20DE route. I nearly bought the motor below before finally putting DET into it just recently.

Had all sorts of tweaking, Nismo 296 duration cams, extensive head work, Jun bottom end, circa 250PS easily.





If your on a budget, stick it out with the early S13 SR20DE; Pulsar N15 N1 pistons, high lift cams, extensive port work. Nismo N2 4 throttle kits are still popping up used here and there but mind you will have to switch over to airflow less CPU.

Ill be going back to S13 with this sort of build down the road. Totally regret tweaking the S14, just a heavier car and not true to N2 racing routes as the S13 was.

Matej

Please do teach me more about this, or point me to some literature.
I have been seriously considering selling my SR20DET and finding an SR20DE.
Mainly because I do not really feel like dealing with turbo stuff, and the SR20DE seems like an even simpler, smaller, and lighter KA.

codyace

I mean this in the nicest way possible, but if you can't handle working with a simple det, than an involved DE isn't the way to go (having had MANY friends do the same)

Matej

My aspirations are nowhere near that motor, I am only curious. Mainly about the Reytec ECU.
If I do go for the DE, it will just be a plug-and-play swap with some generic bolt-on parts.
And it is not that I cannot handle my DET, I just do not really care to anymore.

Croustibat

TBH i could not care less. I dont care where it comes, the KA24DE has nothing to do under the hood of a sports car, it just is a reliable engine with no power.

You can either believe the crap you did read on wikipedia or think for yourself.
Truth is America is the only place in the world where you get that engine in an S13/S14 chassis, and not the only place where Z31 NA was sold. Seeing how turbo CA/SR need frequent maintenance, they would just have massively failed in the US, which would be much worse than having more power than the bigger GT model from the same seller.


Anyway, any LSx engine is quite fun in these. There also are some fab kits to fit them quite easily.

inopsey

nice to see you have your head up your ass again and only believe what you think is true.

Slammed Assassin

Ive had good experience with vq thus far..
