random question but seriously asking

[martins_240sx]

okay so in my boredom thoughts i started thinking....if a turboed engine adds a "T" to the engine code....Ka24e-"t"then what does a supercharged engine get...Ive seen "Sc", "S", and "R"and on that same note what would a twincharged engine get..."ScT"?I know its random and maybe a little dumb but through all of my twincharging research ive been doin for my new project, this question was put in my head.

[duffman1278]

It adds the letter J for JDM

[martins_240sx]

hahahaha. no but seriously. I think im stickin with ka24e-ScT

[troskinatior]

im pretty sure its R

[NismoRacer34]

WOW, this actually crossed my mind this morning.

[martins_240sx]

good to know im not the only one...why an "R"?This seems to be the only nissan production twin charged vehicleMA09-ERT - 930cc - OHC 3 cylinder, 6 valve, turbo and supercharged, EFI - 110hp - March Super Turbo (1989)as you all can see they do use an "R"so to answer my own question it will be ka24ert

twin supercharged? twin turbo would obviously be TT ive never seen a twin supercharged car

[mrgreeneyes]

R is the letter nissan used for supercharged motors.

aka frontiers and the like.

so it would be a KA24DER if nissan were to name it according to their logic

twin supercharged? twin turbo would obviously be TT ive never seen a twin supercharged car

you did not understand me...Im turboed and going supercharged as well.i edited my post up there, but here you go again.MA09-ERT - 930cc - OHC 3 cylinder, 6 valve, turbo and supercharged, EFI - 110hp - March Super Turbo (1989) as far as I can find nissans only twin charged vehicle. oh and im sohc mr. green eyes leaving me with a ka24ert when i get back home to install the SC any way.

i see now. dont call it any letters or anything.

call it f***ing badass. twin-charged SOHC... damn. DO IT!

[OM3GA]

come on its common sense

SOHC Kompressor

DOHC Kompressor

There is an engine code breakdown thread somewhere.

E is single cameDE is twin camT is turboTT is twin TurboR is superchargedHR is high rev

Twin changing is turbo and supercharging, looks like this http://www.youtube.com/watch?v=4SjNgVH_HN0

[AZ89two4Tsx]

^ That thing is badass!

Can't forget HO too. High output. lol

[martins_240sx]

I will be doin it for sure...It should be very easy concidering ive got everthing already strapped to my sohc. just bolt on and take it back to the dyno. Ive just got to redo my cold pipe and make another for the supercharger feed and tb. Ill prolly end up doin a whole bunch of other stuff too. but i cant start till mid march due to training but stay tuned on my build "true pig"

[SirSilvia]

LOL AZ89two4Tsx I have adblocked your avatar

[xX RB Xx]

Z as in 4agze in the mr2. The same motor as the corollas 4age but supercharged.

[Tsukiko]

never cared for either the 4AGE or 4AGZE.

Homie of mine had a built GZE in a rolla that i borrowed at one point. I have no idea why the SC only kicked in at a ridiculous RPM, like 7K. Its bark was WAAYYYY worse than its bite.

[xX RB Xx]

Are you sure it was sc? Alot of people use the GZE block because it's 7 rib just like the 20v. The 86 blocks are 3 rib.

[martins_240sx]

It has begun.........muahahahaha

[xX RB Xx]

ha, it will probably never be finished!

[martins_240sx]

hey that aint nice.... No I cant even start it really till march since im on the other side of the usa right now. Being a Marine is a busy job sometimes but trust me it will get done. I will keep all the updates on my build page "True Pig Build"

is the supercharger pulley an a/c compressor clutch..... mad max style

[SirSilvia]

good god, i wasn't able to see this pic while it was blocked at work, but that's hella sexy

[DMan II-40]

What about KA24E-TR

the - (dash) needs to be there because it is added.

It would have to have some sort of clutch on it, seeing that the s/c is normally used to spool the turbo. I say, save yourself some money and headache and get a 50 shot wet system to spool the turbo faster. I dont think the s/c and the turbo can work simultaniously can they?

[numbnuts240]

sure they can

Technical descriptionA twincharging system combines a supercharger and turbocharger in a complementary arrangement, with the intent of one component's advantage compensating for the other component's disadvantage. There are several different twincharging configurations. The two most common are series, and parallel.

Series systems, the more common of the two, are plumbed such that one compressor's output feeds the inlet of another. It is a sequentially-organized Roots type supercharger, connected to a medium- to large-sized turbocharger.[citation needed] The supercharger provides near-instant manifold pressure (eliminating turbo lag, which would otherwise result when the turbocharger is not up to its operating speed). Once the turbocharger has reached operating speed, the supercharger can either continue contributing air to the intake (yielding elevated intake pressures), or it can be bypassed and mechanically decoupled from the drivetrain via an electromagnetic clutch (increasing efficiency of the induction system).

Other series configurations exist where no bypass system is employed and both compressors are in continuous duty. As a result, compounded boost is always produced as the pressure ratios of the two compressors combine. This form of series twincharging allows for the production of boost pressures that would otherwise be unachievable with other compressor arrangements. A significant advantage of this method is the reduction in charge temperature for a given pressure output versus that of a single compressor producing the same output.

Parallel systems typically always require the use of a bypass or diverter valve to "select" which compressor is feeding the engine. Parallel systems are not compounded by design, and maximum manifold pressure will be equal to the maximum output of the compressors, whichever is greatest. Parallel systems often employ complex electronics to control bypass valves selecting which compressor is utilized depending on several engine parameters, driver inputs, and environmental factors. Mechanically-controlled parallel twincharged systems typically cannot provide a transparent and seamless switch between compressors. As a result, power delivery can have abrubt spikes.

that sr is ran in parrallel I will be running in series.thank you wakopedia....also to "me" nos is lazyness. thats just to me. granted once you get to a point it can be benificial. but you run out all the time and your gains are only there if you have nos in your tank. also how many people can say they have a twin charged ka24e?
