hi, im from the honda world- im use to being able to take a tubro off anything- fab up a manifold- runs some lines and rechip the ECU- is this possible with the KA24DE (2.4L) I know guys do it with the 240- but those are OBD and OBDI---

I have all my parts left over from my previous LS VTech turbo setup and it would be very nice to add some breath to my small lung 2.4 X-

from what i have heard thats not such a good idea to run turbo on an x but hey man if you did it you'd probably be the first. that would be kinda cool. and i love the sound of a bov....even if it is on an x lol

FUEL MANAGEMENT anyone- what are the options on the X- this is really my ONLY concern

couldnt tell ya man, i think youd be the first to attempt this, but i think it would be easier with the ka24 rather than the vg33

i agree with ricer about it being easier to mod out the 4 banger rather the V6.... if you do end up doing it post alot of pics and some good write ups on it cause i bet there are alot of people that have been thinking about dong this.... good luck

I will do it, but i need someone with engine management experience with the Xterra- dude i dont even know where the ECU is on this thing.....i know engines and i know turbos...I cant really afford to trash this thing because it is my DD

but whats the difference between a ka in the X and a ka in a 240? people turbo the ka in the 240 all the time because its cheaper and you get similar results as an sr swap. couldnt imagine it being different than doing it in a 240

I don't see why you couldn't just run an S-AFC for the fuel? It's still a nissan ECU so it should have the same wire-taps. If not, you'd just need to find what wires are what for the X's ECU and go from there...

Correct me if I'm wrong but you would only need to find the airflow, RPM, and throttle signals? (and knock, if you need to know.)

i wouldn't see the point in turboing a X!!!!! the turbo would do nothing off road.... they take high rpm's to spool..... that is the reason Nissan went with the S.C. edition....... all time boost....


when they turbo the 240 they do it for the speed correct???? you also have to consider that the 240 is a small car and the X weighs alot more.....

http://www.jimwolftechnology.com/. Call them up to see if they can work with the ecu on an xterra.http://www.technosquareinc.com/Here is another company to contact.Both of these specialize in nissans.Good Luck.

Most people I know turbo the 240's for more power for drifting. Actually they just do an engine swap. But now that you mention it if you used a stock silvia turbo, which I believe is a T28(?) on a 2.4L it would spool up pretty quickly. Now make that a ball bearing t28 (GT2871R) and you're hitting full boost roughly around 2k? I can't imagine you'd be trying to run big boost, therefor making 8-9psi max relatively quickly should be easy to pull off...

Of course, like json said, the supercharger is instant and you can't get any quicker than that...

if im not mistaken the SC gives you around the same boost asd the turbo mentioned above....

The 2.4L from my understanding only comes in a 4x2. No 4x4's were made with that engine. I don't think the 2.4 would be able to push the truck in 4wd. but then again I might be wrong.

if it can push it in 2wd, it should be able to push it in 4x4

while you're at it, just swap in an RB series motor lol, it could be the new Xterra GTR

The problem with the roots style supercharger that comes stock on the xterra (or on any car) is the parasitic loss you get .After 5 grand the efficiency goes way down.On a svt lighting we dynoed the computer estimated it was taking around 85 horses just to turn it.The turbo once it does spool up pulls strong all the way to redline.A centrifugal supercharger will also pull strong to redline but its power is not instant like the roots, its power is more gradual so it would be useless for our vehicles. On an xterra this is where the roots shines because these motors hardly ever spin over 5500 rpms or at least they shouldn't unless you changed the valve train to handle it which I would assume you would do if you turbo it.You will definitely get the wow factor going on when you opened up the hood and saw a turbo sitting in the engine bay.If you are going to go with the KA25DE I would troll the 240 sx or altima boards for info on prepping the motor for a turbo.As far as fuel management if JWT doesn't work on our ecu's you'll probably have to shell out some bucks for a stand alone system.F.A.S.T.,AEM,or Mega Squirt.Greddy make a great piggyback ecu for nissan the ultimate e-manage or the e-manage blue but I don't know if the software is compatible with the xterra's ecu.Good luck with the build and keep us update.

well the HRPM spool would be from a single giant turbo. if you did a twin turbo set up you can have one turbo spool in the lower rpms and one spool in the higher rpms. however youd be running a lot of pipes and oil lines etc and taking up a lot of room in the engine bay.

however if you went with a S/C it would be a lot easier to do.

but that is my opinion. but hey if you do do this please post a lot of pics cause i will probably follow suite with a TT set up for the 07 that or a S/C havent really decided yet.

there is only one guy that has a 2nd gen on a S/C and that is S_e_X-Terra pull up some of his threads... look awsome.....

I have seen 2.4 s/c on frontiers using the stock s/c from the 3.3's There should be no big diff. between the 2.4 from the X/ frontys and the last gen 240s. THey made the 240sx up untill 97. obdII was used if only for one or two years. Im pretty sure the 240s where DOHC but for sure the 2.4 frontys and Xs are. I like what i have seen from S/C 2.4 the S/C is mounted upside down using the lower intake from a 240, and at first glance you cant even see the S/C under the hood..a total sleeper. The biggest diff. form the 2.4s is the intake and bottom end from what I remember.
