Ka24de-t vs. L28et

KingDatsun1 · 04-08-2009, 07:57 PM

hello there everyone,

as of saturday, I will be purchasing another Z, (hopefully) a 260 or 240, to restore and make into a monsterous road car.

Interior will be stripped, etc etc, painted flat black, if it doesn't need to be used to make the car run...bye bye. lol

However, I'm considering two motors for this project, at L28ET and a KA24DE-T.

I'm looking for around 450rwhp, I've seen L28's with 600hp and KA-T's with 1000hp, but I'm more concerned with an outrageous price over anything.

both motors are fairly cheap, I would love to keep an L28, but just how hard is it to make it get to 450hp? (yes, I've read several turbo write ups and still don't know the answer)

could I get there for under 5-6 grand?

(this is a long term project, I just want to make a decision on a motor to buy for the future.)

thanks Z community

Moved to S30 section...

We just had a thread on "600hp L28's" which is pretty unrealistic (especially for a $5k-$6k budget). The 4cyl gives a weight distribution benefit, the inline six is simple. It's all up to you.

The real question: Do you know how to build a good turbo motor?

280zx2by2 · 04-08-2009, 08:44 PM

why consider KA when there is the SR? i mean the KA is ok for that dude that's trying to prove something (prove what i do not know) but if i had a s30 striped and ready for any engine... i would have to go SBC or SR (probably SBC because im in the deep south, people would lol at me for swapping in a smaller engine)

but if you are that guy trying to prove something i wouldn't mind seeing a KA s30... go to a 240sx site and ask them (mabe search so they dont lol at you for asking what i assume is a noob question to them)

EDIT...
I actually used to be against the 4cyl into an S30, but after seeing the benefits... I kinda like it.

the sr is a very sexy motor. the ka is a beast itself. the sr will hold more power but 450 you should be ok with a ka. do you have a budget? 450 out of a l28 can be seen but again just like the inline 4 it all comes down to money and what parts you buy. Of course you will find aftermarket stuff easier with the ka and sr. if your looking for a swap and want for sure power why not the rb or 2jz? hell even the sbc is a great swap unless your stuck on a nissan engine. i thought really hard about a sr. had a guy local selling a red top sr20det. almost jumped on it. i waited and found a late turbo 87 z31. gonna try and be different throwing in a vg30et. a couple people have done it and the vg itself is a very BEEFY engine. of course everyone has their own preferences. i planning on some power with it

snwbrderphat540 · 04-08-2009, 10:26 PM

LOL nismo thats the same video that made me fall in love

but im indifferent between the SR and the KA. i think i lean more towards the KA because they have proven to have the same potential and mre readily available and cheaper since they arent a JDM only motor

http://videos.streetfire.net/video/I...the_131834.htm

http://videos.streetfire.net/video/A...157_113923.htm

ivan's 240 is beast. a KA swap would be great for me living so close to AMS. but.... think of the fabbing

i can't do that work. otherwise it would be done so. and 1000hp KA's ? idk about THAT high, but they do put down better number than any L motor i've seen. modified OF COURSE.

KingDatsun1 · 04-09-2009, 09:46 AM

SR's are like 2 grand, I can get a KA for 150 bucks probably, by then I can already start upgrading internals etc.

Heavy throttle has a turbo kit for an SR thats like a bolt on 500hp. It also costs 5 grand, so I'm not sure.

spending that same amount of money on a KA, (7 grand) I think I could easily have a ton more hp lol

the KA's block is indestructible supposedly,

I'm tending to lean towards a KA over the common SR swap.

I'm in spanish class right now, and the youtube site is blocked. Is that the 500 hp SR 240z the guy from england has?

I love it.

snwbrderphat540 · 04-09-2009, 09:54 AM

does the KA share all the same mounts as the SR? or are they different? i cant remember if the SR is a straight drop in the SX's or if they have mount kits....

duowing · 04-09-2009, 11:17 AM

Man after that video...SR Z seems pretty wild. I like it! I have to admit I never was a fan of a 4-cylinder in a Z, but after that I just can't imagine the looks on people's faces when they see what pushes that thing around.

theramz · 04-09-2009, 12:20 PM

If you havn't seen this yet go to youtube 280z turbo 10 sec(Zperformanceracing). Cheap go fast recipe.

Sweets · 04-09-2009, 01:02 PM

Sr's suck. They are expensive, and barely (if any) more capable than a twin cam KA. You can get good running KA for under $400. With a cheap turbo kit and a decent turbo you can pull off 250whp with a tune.

And a $1800 SR will MAYBE get you 180whp out of the box.

SR = jdm flash, expensive, parts are harder to find than a KA. But its already turbo.
KA = dirt cheap, lots of bolt-ons available, your local junkyard will have extra pistons when you turn the boost up too high.
L28et = reliable, you already know how it works. But its expensive to squeeze power from.

EDIT: Have you considered a RB25 or RB20? You can pick up 20's for under 1k.

a 76 "280zx", stock internals, stock ecu, 18psi boost ... 10 sec 1/4mi? I think they "left out" some details...

Yeah, look at the seats lol That is a low buck ride if I ever saw one!

jwk2w · 04-09-2009, 07:28 PM

go with the ka. the stock ka can produce up to 500 hp with stock internals. Just put a mls head gasket on and arp head bolts on.

The ka has real good low end torque and with a turbo it's even better and you know everyone loves the torque.

NismoPick · 04-09-2009, 07:31 PM

Torque FTW!!!

280zx2by2 · 04-09-2009, 07:53 PM

want to fall in love with the RB swap again?

It has torque! It may be at 5500rpm but its still torque lol

lww · 04-12-2009, 12:15 AM

I prefer the torque curve to quickly max out LOW in the rpm band and then stay flat all the way to red line. It's not about "peak" power, it's about the maximum AVERAGE power produced throughout the entire useful rpm range.

That being said, I love SR20DET swaps in 510's and S13/4/5's.

But not a Z.
