KA24ETT ;)

[sohcsleeper]

im working on a turbo kit for my car as we speak im going tt on my 240sx with a fully built (head and block) ka24e i have had massive work done to the sohc motor im twin turboing i think it will be worth it in the long run im shooting for 600whp i already have the engine built for the turbo's all i need is for my uncle to weld the twin turbo manifold (hes like the best welder i ever met) after the manifold is done im gonna order the turbos i want

2 t3/t04e turbos,big *** fmic,walbro fuel pump,bigger injectors(havent figured out what size im going to need yet),bigger rail(havent decided yet),a vlsd with longer final drive(possibley the 3.7 vlsd),aem stand alone fmuim having my friend tune it on a dyno at his schooloil coolerguagescobra mafstrying to get a bigger throttle body(no clue)

if anyone has any clue of what i can use for the throttle body or any sugguestions let me know after its all up and running ill post pics and maybe a vid

wow.n Awesome. That's gonna rock! keep us posted.

x2 please let us know how it all goes

You may want to rethink using twin t3/t04e's. Those are fairly sized turbos and you will be hard pressed to spool both of those up efficiently on an inline 4 sohc. Otherwise, if you've got the money, time, and patience, go for it.

[sohcsleeper]

i want big turbos it will lag but as soon as i hit boost with the gears streched out a lil bit i can stay on boost through every gear = great for drag

[sohcsleeper]

i want it to boost around 3500-4000 rpm all the way to redline

[KATwo40]

I'd opt for an auto trans, if I were you. You could mate a TH400 to it and use a high stall system (trans brake + stall converter). That way, you can begin loading the engine and spooling the turbos before the lights drop.

If it's a drag car you're building.

i don't agree with the turbo choice either. spooling up 2 of those turbos by 4k is gonna be a joke.

good luck though. sounds like a fun project.

Yeah, really... a single turbo, T4 won't spoll till around that.. you're going to have to use smaller turbos, which means less boost... I don't know about that idea.. why not get a nice, big T4 and boost the crap outta that.. i'd say it would be a lot more effecient.. espeically on a SOHC 2.4l 4CYL..

but I don't know anything.

[nismofly]

i also agree that since one t3/t04e spools by about 3500, two cant possibly with each having half the flow

walbro fuel pump

going to need either a bigger pump, or 2 walbros with that power goal

You can send your stock throttle body off to this place, and he will bore it out for you. Someone else on here did that a while back. And it only costs you about $100. You can probly find the thread on here if you search "maxbore".

Here's a link the the website though.http://www.maxbore.com/

Well if you look through his posting history, you'll see he still has a lot to learn about the 240's and what's possible with them.

zer...eeper

I suggest to the orginal poster to do more research here. I think there are a lot more viable options for a 240sx drag car than just saying you're going to twin turbo it.

[sohcsleeper]

who are you to tell me it's not possible yea its a pair of big turbo's but that doesnt mean thats deffenitly what im going for i havent decided on what turbo's to use yet

i was thinking about t3/t04e's they are a lil big though maybe i could have a twin garret t25 setup or somthing similarmaybe i wont make 600hp with my sohc then again maybe i will but i gaurentee you that i will have over 400hp

2 t25's will boost before or right at 4k all day

i am willing to bet that ill have a better 1/4 mile time than anyone in a 240sx that you know in less then a month from now ill post pics vids and drag slips just for you ***hole

i really want to be the first one to twin turbo a sohc motor but i dont know if its been done yet

i already built the motor for my turbo setup and im not just saying "im gonna twin turbo my 240sx" lmao i originally wanted a single t3/t04e turbo but i was thinking about other options and my uncle said he could weld a manifold for a dual turbo setup so i was like **** it i want the first twin turbo sohc 240sx i have about 4k to spend on the turbo kit me and my uncle are installing everything

if it doesnt work it doesnt work thats still no reason to be an ***hole and knock me for trying

It may not be about what is "possible" to do to the SOHC. Rather, what is possible in terms of spool up time, and efficiency.

All I have to say to that is, flamebait.

Just admit you haven't done nearly as much research and move along. Your not going to prove anyything with that attitude.

why is that flamebait because im building a drag/track car?

again you people are ***holes. i dont know why you even bother posting if all you got is negitive sh*t to say

LoL... okay, you do that then.. the only thing I can see working, which someone is already a lot further in the process than you, is a sequential turbo setup, on the sohc.. he's using a small t3 to spool up a lager t4....

I don't see how you can spool up a t3/t4 on 2 cyl each.

So, you're using a MAF, with your stand alone.. my I ask why? especially trying to use 1 maf, for 2 large turbos..

[sohcsleeper]

ok maybe i havent done that much research on it but i just decided to go twin turbo 2 days ago i mean im not the best mechanic in the world or the smartest guy but i have common sense and i can learn anything plus the fact that im already farther along then alot of people i have the cash to spend on the kit and i have the motor already built for turbo

why be a *ick about it. why not try to explain somthing and teach instead of showing your ignorance by posting a comment like that you make no sence why are you even on the forums

if yall know so much more then me why not try to help me instead of acting like stuck up ***holes

and i already ruled the 2 t3/t4's out thinking about 2 t25 stock sr turbo's anyone have any input on this that isnt negitive?

Haha, nice....

Anyways... I figured if you were acually serious about doing a twin turbo on your sohc, that you would probably know what you're doing.. so.. Why do you even want to do twin turbos? I mean.. most people with twin turbos on rb26dett, or the 2jz supra engine, convert to single turbo.. why? because with one BIG turbo, you can run more boost, make more power, less heat, and it's cheaper... two SMALLER turbos can't handle much boost, get very hot, and thus, make less power, unless a lot of money is spent.. I say, if you want a 600whp SOHC drag car, use one turbo. 600whp would be quite an accomplishment anyways, and would surprise a lot of people. I don't know THAT much about this stuff, but it seems that even 2x T25's would take a long time to make even 15psi of boost by redline..

[pr240sx]

What about using two T3 with small exhaust AR and big as hell compressor?

With a good turbo header, I think that 2, 2.4 cylinders will move that turbo.You may need to go with the ball bearing option and plumbing is going to be hell, but is doable.

[Structure240sx]

i skimmed through most of the flame-age

how are you going to make a manifold before having the turbos you are going to use? you cant just make a manifold with two turbo flanges and think its going to work.

we get on people like this because the ka has had a bad name in the import world. everyone thinks its crap and wont hold power. its when people do half *** attemps to boost it it makes us look bad. luckily you plan on a built motor jsut hopefully with good tunning so it stays together

[teddy]

Just to let you know..running 2 t25's would be about the equivalent of running one larger single turbo. The reason you usually see twin turbos only on inline 6's and larger are because they have enough energy to spool the 2 t28's and do it well. The reason most people run single turbo's on 4 cylinders is because it is easier to spool one, easier to make power efficiently, and because the single turbo will generate less heat than the two smaller ones with the boost increased.

Also, the member andrave has/had a ka24dett. I'm not sure if it ever got running properly or not, but I do know he was selling a lot of his parts. Maybe he will chime in and give you some pro's and cons to the whole thing.

[Chezedik]

I am sorry, I just have to ask why this post isn't locked yet? It seems to me it is just an excuse for a noob to try and bash on the members, when I would be willing to bet he hasn't searched.

[WDRacing]

I ran that same turbo and in single form I saw full boosta round 3400 on a log manifold...so you WILL NOT spool a set of twins till atleast 5000 will full boost hitting about 5500-5700. That gives you a decent setup for drag if you can keep them spooled between shifts and use N2O to help off the line.

In reality, a car that is used for a dily driver and only wants 600whp...twins is a poor way to go.

I'm all for checking it out. Persoanlly, why not use 2530's. My buddy put down 640 to all 4 wheels of his GTR with a set of those and the lag will be minimal. A far better choice IMO, but thats on you.

[Florida240sx]

All your going to have is a dyno queen. A single turbo is much more efficient, and a whole lot of less work. I was on the same path as you to go twin turbo.Which will be great for 400rwhp.But anything over that you justed wasted time and $$$ your goal is 600rwhp so twin turbo idea should be thrown out the door. It's nice that you got the $$ and you got the resources to get it done.BUT maybe you should sit down and look at what you are about to do. Your goign to be wasting $$$.If you want that high hp get like a pt67 and use a bit of spray to help it. Also being you made the stupid comment of having the fastest 240sx.What is your suspension goign to be, what clutch you goign to use, what rims and tires you going to use, what brakes are you going to have, have you already braced your frame?, what kind of ignition setup you running, where are you going to get your race gas?, and who makes your chute?

[crzycav86]

lol @ this thread.

Why don't you do a single turbo setup first? Then if you want to afterward, go ahead and do the tt. All the while, you'll need to do some research. ..and I don't think you realize the big jump you made from twin t3/t04e's to twin t25's. It just proves you've got a lot to learn.. so start now.

um, he got banned...like a year ago

might be difficult

[fabio420]

2 small t3's with a 42 turbine and 48 compressor are awesome for a twin setup. When I ran it single, it spooled fully (14psi) 3200 rpms. it hit 260rwhp. but it droppedb boost @5500 rpm. If one were to have two of these turbos, the spool woould be real quck and strong with great torque, and being that there is 2 of them , you could prbly boost high teen and not drop any boost. That's what I think.P.S. notice how I cut through the insults and attacks and just stuck to the topic at hand (minus opinions)

[WDRacing]

Andrave never had a twin setup running. He got banned because he was a **** talking loser.
