The mighty 2jz or The legendary RB26

[[PIMPIN]]

Hi....correct me if im wrong Toyota outsourced the building of the 2jz engine and trans to the Germans in order to compete with the rb26..I feel a proper build RWD can outsprint a 4WD (0-400m) if we put the supra side by side with the 34gtr.. (just for direct comparison(drag race)

Getrag makes the gearboxes for both GTR and Supras. Naturally there are differences but if anyone knows the ratios would be cool to compare. Engine I'm not sure, but IIRC Yamaha made the head for the 1JZs but whether this was same deal with 2JZ only a Supra fan could tell us.

Stock vs stock the GTR would beat the Supra in a quarter mile race. Once you start modifying, well then its a different story. Are we talking about street driven, road tires but high HP or pure drag cars with slicks, parachutes etc? I believe that in street trim, if a GTR and Supra were equaly modified and ran same compound tires then definately the GTR's launch would almost always give it the advantage - driver ability aside.

Bump: The cost of building a 600hp RB26 or 2JZ very much depends on what parts you use. Can spend obscene amounts if you insist only on branded parts from Japan or can get just as good a setup for much less. It all depends on the wallet.

Let's assume both cars are 100% stock standard. What parts do you guys reckon the RB26 and 2JZ need for 600hp (engine or at the wheels?). We can see what sort of estimates people come up with.

haha.... RB26DETT is by far the best engine out there. ;)
no other can compare. muahaha

what an interesting topic to pop up, especially at a time when I'm half comtemplating of buying a Supra...would need to do lots more research still, but I like what Ive seen so far. basically comparing 2 inline-6 engines, only thing 2jz has higher displacement... Not too much of a tech junkie but I think i'll vote for 2jz, coz of stronger stock internals. Performance wise, none is better than the other coz it all depends on how well they are tuned, modded, and taken care of... end of the day, they r both man made marvels...

Nice...due the nature of a 4wd car which will distribute the extra torque to the front thus creating wheel spin at the front distubing the weight disribution (comes in suddene and hard) where else a rear wheel car will distribute all its power to the rear thus distributing the whole weight of the car (depends on suspension set up at the rear..some say the oem susp is good enough due to its softness) to the rear wheels ,ths makes the car squat(pressing onto the rear wheels) making the tyres stick to the ground(helps traction..depending on tyre compound/side wall) and slingshot the car to a quick time (0-400m)...oh ya they do make good tyres for street/track nowdays

 

[BLaCkHoWLiNG]

actually to be frank, both RB and 2JZ are bloody lazy engines at stock form... both engine has potentials and can extend as far your pocket can afford... but 2JZ has stronger internals. In the states, some are able to run 900hp on stock internals.... as for RB26... i heard and witnessed a few that failed at 600... so RB owners gotta have deeper pockets..... but somehow, if u compare 1J with RB25... well, ask ceffy owners.. they'll let u know their preferences ;)

Actually its true what you've said about the stock suspension. I used to know a couple of guys with R32GTRs back in Perth who would run stock rear suspension but slightly stiffer aftermarket ones up front. Worked pretty well too, cause one ran easy 12's with very basic mods and the other 11's naturally with more work done. I remember the early days of experimenting - trying various tire pressures but the best was this guy who had a few stacks of scrap paper in his boot ROFL.

The GTR will still 'squat' however since its not full time 4wd until its beloved attessa works its magic. The weight doesn't really shift to the front when you accelerate forward would it? When you brake the weight pitches forward instead kan?

 

[shark79]

yup the gtr will squat but not for long as the power will be distributed to the front taking away the pressure from the back...the weight doesnt shift to the front but what happens is bcoz of the 4wd power will be distributed near perfect to all the wheels this will lead to not enough weight shifted to the rear...remember the rear will come into play first then the front ...so by the time the front can compensate for the lost of traction at the rear it will be too late...its about split sec in drag racing...no doubt there are 6/7sec gtr but the record holder is still a rear wheel drive car

 

[[PIMPIN]]

I don't understand. Why is weight being at the rear so important?

Drag racing is all about getting the power to the ground, as fast as possible and with as much forward traction as can be achieved in order to cover the distance in the shortest elapsed time. That's what the ATTESA system does. It distributes torque to all four wheels as fast as possible. Shouldn't the system be expected to overcome whatever weight distribution issues, etc therefore getting power to all four wheels?

Granted, all the fastest drag cars are RWD but those that do the 400m dash in 7secs and faster can barely be called cars. I'm more interested in comparing real road driven cars - fast, modified but still streetable, not tube frame chassis, etc or top fuel dragsters. The type you might run into on NKVE or something hahah

Eh i thought this 2J vs RB26 topic?hehehe

Bro PIMPIN,

WHY?Still confusing yea hehe.This is Physic, Newton`s Law....we called it INERTIA
"objects at rest tend to stay at rest."

It`s same feeling once u take corner/turn, Eg: turn left,but ur car weight/body shifting to right side.So the accelaration of car will shift most weight to the rear~

I would say ATTESA-Pro on BNR34 is smart torque distributor by reducing wheel spinning to all wheels.From stand point 20:80 then 30:70 then 40:60.On BNR32 is fix 40:60...so they need aftermarket torque distributor to adjust it.

By PULL or PUSH law, FR is more advantage rather than FF which happen losing traction since wheel spinning regardless their HP.On the other hands, AWD is HEAVY with those extra longshaft,driveshaft and gearbox but would be solve by POWER to Weight ratio.

:)

aiya. u guys still thinking which is the best ar?
see the ultimate 6 inline challenge which is participated by the mine's GTR n the monster supra.
2jz is memang power but its not as stable if compared to the rb.

 

[jinkl]

i would say
i will vote for the 2jz, first it price wise, its so much cheaper
2nd thing, u dnt need to disturb the internals and oil pump or etc to slap it hard
technology wise i would vote for the rb26 , bt its going to take a lot of more cash to make it a beast , this if im talking 2jz and rb26 in the same kind of body, minus the transmission

 

[cosmicgate]

actually the first stage tuning of 2jz is cheaper than rb26, after that it can get really deep, but still cheaper lah compared to rb26.

so have we drew a conclusion yet to which is the better engine?

rB!! 2JZ is designed by motosikal company.. fucking useless... stay away from 2jz!!

and also worthless piece of junk! my 2jz halfcut cost me rm3k only! how can cheap items be good?

 

[cmng]

yea.. it a junk engine

so blackhowling
i offer you RM4k for your engine turbo , the 6 speed gearbox. ecu, wiring bla bla bla
