hmmm 2jz in a 25t rolling shell would be interesting,

but then again still cheaper to wack on a 3lt bottom end an get hte same power less the high rpms ?

hmm wonder if you could bore a block to a 3lt capacity and not enlarge the stroke hence making higher rpms possible with better cams and making the 3lt power ?

how much thickness is there to play with ? I wonder if there is a block I could use to achieve what I want. .. dished head pistons, bore out a 26 block as they are thicker... mybe an N1 block thicker again..... hmmmmm

i likes my higher rpms.

hahahahahaha... is it juz me or has the topic totaly changed... i think a 2jz in a 34gtr trim would b the ultimate street car... from the pics the job looks pretty crap but maybe they already got the car that way and since it was half ruinned they thought let try something different..

i love skylines but it is common fact that 2jz and 1jz are cheaper and better engines then rb26 / 25... but for me the overall benefits of puttin a 2jz into a gtr would be hardly worth the $$$ or the hastle... but then again these guys obviously dont care about that... i actually read an article in zoom a few months ago where a guy had a 2jz lying around so he chucked it into his r32 gtst.. and now he runs easy 9s in a full trim street car with fairly mild mods (for a 9 sec car)... i guess if u got the $$$ and the means to do it then go for it but i know if i had the $$$ i would just buy a mine's gtr from japan and im sure i b more then happy...

that r32 gtst had a 7m toyota motor not a 2jz and yes it runs 9s with some mods. its from TRP workshop.

they said they are switching to a 2jz soon as the 7m is now in a datto 1200 ute :laugh:

not a bad idea except for the price of a N1 block u can get a 2jz and a bit left over for a few mods...

I saw that rigoli 32 on the road not long after he built it on parramatta rd. pulled up next to him in a friends WRX and my other friend recognised Tony Rigoli. Yelled out "are you tony rigoli? how much for a 10 sec package on this wrx?", he yelled out "buy this skyline instead", and launched it doing fishy's accross three lanes up the road.

oops sorry ur right... i just dug up the article... but yeah if u can get that sort of performance with a 7m then i would love to see it with the 2jz..

How difficult would it be to engineer a 2JZ into a 33 GTS rolling shell. I was looking at sinking at least 10-15K into my RB25 but now you put ideas in my head...

i dont think that be enought for a good quality job... i know when i had a civic and wanted an engine swap the engine was around $2500 but everyone told me i will be looking at close to $10k... and that was for a simple swap with not much custom work...

I was planning on making my car a Sunday special after a few years of daily driving. Other than custom engine mounts and custom gearbox bell housing would it be to hard to bolt everything else up or is there more shit to worry about? That is to say that the 2JZ is out of a front cut and running a custom ECU with all other components in working order?

That aside how much fun would a stock looking 25T be with an 800HP 2JZ under the bonnet!

Did anyone say stealth :laugh:

Yeah a nice sleeper is always cool... im not sure what else would need to be custom... but all i know is that engine swaps always blow out of proportion and out of budget... if u got the money for it then talk to a few workshops and see what they say but if it was me i would blow the 10k on the rb and have a very nice toy to play with on sundays... plus dont forget you would also need to spend money on suspension and braking...

Hehe, my old race mechanic had a 302 Windsor V8 putting out about 400hp under the bonnet of a 1976 264 Volvo. Supra 5 speed and a Jag indie rear suspention set up. That was the most insane fun car to drive in cause it came out of nowhere and you could leave it parked anywhere with the keys in the ignition n no one would take it.

Well there are bout 10000000 white R33 Gtsts floating around syd so it would be pretty cool to have a stocko stealth car that would shread anything!

dont forget u need a 5 speed box or 6 speed if ya rich, as most 2jz cuts are aristo models and auto.

w58 i think is the 1jz 5 speed box and suitable for the 2jz, they are about 2k and pretty rare to get hold of.

2jz 6 speed is some bullshit price last time i checked and not really worth it over the w58.

u got engine, box, clutch, ecu, turbo (stockies are shit), cooler, piping, engine mounts, exhuast, tailshaft, sump might be an issue?, wiring to factory dash, speedo, and general other bits and pieces. i would go a 2jz in a r33 gts-t anyday if i had the choice between that and doing a rb25 setup.

stock 2jz are making 800-900hp at wheels safely (a rare few have gone over 1000hp) in the states but remember this is on there dynos which read alot higher (someone mentions 20% higher in some other threads). but u will never see a rb26 survive for long on even 500-600hp at wheels thats for sure.

2jz ftw :sick:

i'd go a 2jz in my stagea but its 4wd :)

are there any differances between the jap spec and the US spec 2jz? i only know the US spec have steel turbine wheels, any other differance (pistons, rods, injectors)?????

wouldnt have a clue sorry, im only into nissans i have a mate into the toyotas so ive learnt alot off his work.

the 1jz box is actually the r154

2jz yank version has diff turbos, but they are still rather crap and a big single is more worthwhile and i have a funny felling they have different style injectors too, but thats only a guess.

2jz with a gt35/40 or gt40 or even t04z would be something to see :)

Not sure about the crossmember in the Skylines, but to put an aristo 2JZ into a Supra, you need the Supra rear mount sump, as the aristo is mid mount.

The R154 is the 1JZ 5spd, and the strongest option out there next to the Getgrag V160. The W58 will break far easier, and is the 7M or 2JZ-GE box.

Also I've been told Aristo's come with slightly larger steel turbo's as opposed to the quicker spooling Supra ceramics.

Also, a 1000rwhp Supra on a dynojet would be roughly an 877rwhp Supra on a Dyno Dynamics.

US Supra's have slightly smaller turbo's, but are steel wheel so can handle more boost.

Also they run500cc (i think) low impedence injectors, while the JDM run 440cc high impedence injectors.

One of the cams is also slightly larger in the US spec, but I can't remember whether it is the intake or exhaust.

Also, none of these things would make a difference when you go for a big build, as they'd all be replaced either way.

Only 1 problem with jz motors, turbos on the wrong side = no good for curcuit racing. Obviously fine for drag cars tho...

If you want 3000ccs in a gtr i think the best way to go about it is building up a a rb30 and if u need over 500hp throw the good bits inside it while ur at it....

If u want 3400ccs get a spacer kit made up for rb30 same as OS do for rb26

I also belive the head design is better in the rb26 from what ive read on here.

That said dollar for dollar the 2J is the winnah! 3000ccs >2600

Or you get heat sheilding made up for the brake and clutch master cylinder, and have the exhaust housing, exhaust manifold and dump all HPC coated.

Not exactly hard.

    • Unless there's something particular about the Greddy manifold's injector holes that I'm not aware of, those injetcors look to be totally wrong. They would absolutely want to be spaced up to get those long snouts out of the runner. Which, I think, is not usually the way that that problem is solved. I think the problem is solved by using the correct injectors, which would be much more like what Andrew posted.
    • Thanks for the reply, So i've continued playing around, and fitted the injector adaptors onto the injector, the fuel rail is not able to be mounted now as the injectors sit a bit further out. I suppose the point of the adaptors is so that the injector nozzle isn't so deep into the intake? I suppose 1mm extra on the o-ring would do it but still can't mount the rail onto the intake haha. Waiting on a reply from Aeroflow I'm sure there's something stupid that I'm missing...
    • EMJ33 or EJM33 - west end
    • I have a radium fuel rail on my Greddy manifold and used the supplied radium fuel injector to manifold adapters (The round green things pictured). I did always wonder if you could just go ahead and use the second lower hole like you're doing... Wouldn't thicker o-rings solve your issue?    
    • From what I've seen and experienced first hand with those powder extinguishers, they're good to use to break a window and escape the car, and half the time then do f**k all to stop a fire. You just need much more than 1KG worth of powder. Not to mention, half the time it's an engine bay fire, and you can't easily, and do not want to completely open the bonnet, so you're left pretending to be an American Infantry... Spray and Pray baby!   And then 100% that shit is really destructive afterwards!   Realistically, those little ones at a race track might help you keep the fire from growing and give the fire marshal / truck a chance to actually get to you with their multiple large bottles.   For a road car, these days, prepare to deboard as quickly as humanly possible, and move to safety. Allow insurance to fix replace it (unless it's like a rare classic etc, then do nearly everything possible to save it!) Keep the little extinguisher with you to help protect other things around you from burning while you stand there singing "How can we sleep while our beds are burning?"   Secondly, powder extinguishers I freaking hate for indoor use, (this isn't really relevant to a car) as you will get a powder fog around you, and it can be disorientating.   When I did fire training when at BlueScope Steel, they have (had?) their own fire brigade on site. We did all the training, and at the end we were told, "If it's an indoor fire, and you need to use a powder extinguisher, we as the fire brigade would rather you just exit the building, you're more likely to get lost in the smoke and powder fog than do much help, so just GTFO" And pretty much that was what they said for most other fires too, grab extinguisher, if it's much more than paper in a bin fire, use extinguisher to get you and others out of the building to safety...   Part of me wishes when my Skyline caught alight many moons ago, I let insurance sort it out, instead of putting the fire out... part of me now says "But I've saved a classic before it was a classic!"
