Rb25de

[dori34]

hey guys, how much power do these engines pull out at the fly and wheels?

thanks.

[skyla]

factory stats at the flywheel for the different models are below, it's hard to gauge power at the wheels, cause every dyno will read sligthly different

R32 RB25DE 132kw

R33 RB25DE non type-s 140kw

R33 RB25DE type-s 147kw

R43 RB25DE 147kw

108.4 rwkw dyno dynamics

108.0 rwkw dyno dynamics

It seems there are significant differntce between cars...

my car had RB25DE but it was GTS4

on dyno made 94kw at all four wheel

cheers

i remember hi performance imports magazine dynoed a rb25de , they eventually got it up to around 120 kw@ rw , mainly by playing with the ignition timing ( advanced few degrees ) improving air inlet and some other tricks . must find that magazine and be a bit more specific .

by the way whats the difference between non type s and type s ?

i read that article too... it was on an series 1 silver sedan.

they advanced timing

fcd

removed standard airbox lid

added a cardboard snorkel

type s has been quoted to have an extra 7kw (and has an exhaust flap on the stock system)

[Greg]

hi mate, what is "fcd"? fuel cut defender? if so what does it do

does the type s get VVT or somehting to give it the extra kw?

[dondesoto]

ah found the magazine article

stock rb25de 105 kw/rw

air intake mods now 110 kw

add fcd now 112 kw

advance base timing 3 degress now 118 kw

custom air intake 121 kw

do you have time to scan it in?

[dondesoto]

do you have time to scan it in?

have tried to scan and upload , but unable to get it to work , but if its any help its issue no 48 of high performance imports .

What sort of power can be achieved with an RB25DE ? Has anyone worked one ?

Have been wanting to change mine to an N/A since I saw a HCR32 modified to fit in an RB25DE ( in the turbo body with brakes etc. ) Yes the car WAS a turbo but had an N/A installed. The RB25DE was very worked but I don't speak Jap so I didn't find out the power output.

I know you think I'm :crazy: but if you could have heard this car go you would cream yourself ( snorting, farting, barking and growling sounds that no turbo car could EVER make !!! )

[Screamin' Skyline]

Na your not nuts FAT32. If I had the money I would get stuck into my RB20DE. And I know the sort of sound your talking about, nothing better than hearing an N/A motor making all it's own power the ol' fashioned way.

:werd:

This car I saw in Osaka had open alloy trumpets and you could look down them and SEE the fuel injector spraying !!! It also had extractors into a 2 3/4" system with one muffler, and then dumped out the side. The compression of the engine was so high that the air coming out the exhaust nearly un-tied your shoe laces !!

I just wish I had done the swap when I blew up my RB20DET. But the only thing that stopped me was the knowledge that I was going to have +200 rwkw. I now have the power but just wish I had the old school noise :kewl:

[meggala]

my r32 rb25de made 105 rwkw with 2 1/4 " exhaust and a good tune we are looking for 120 rwkw if we ever get stuck back into the project

meggala

[TokyoTaxi]

So by that rational, it's possible to get good 150+rwkw with cams, injectors, head work etc. ( I suppose with REAL money spent, the number's could be higher ). But I guess it's more about the torque figure and where it all happens in the rev range.

I better start saving real hard

by that you mean it had their own individual tb with bell mouths added to it. they make the engine scream and rev really loud haha.

damn its been awhile and i should've kept track of this thread. i totally forgot about it

R32 RB25DE 132kw

i thought R32's only came in RB20 dude?

i rekon the rb25de would be a good engine to work with. work it off its nuts then slap on a turbo man it would be a monster.

Yes some R32s came out with a non-turbo RB25DE engine (although less powerful than the R33 version).

yeh, I have an R32 RB25DE.. any light mods I can do? I'm a student so strapped for cash, but it does have a new air filter, performance clutch and exhaust.. what else could be done?

$300 will get you a set of Coby extractors from NZ. Very good build quality!

He said it already has a performance exhaust on it... so any gain would be minimal (surley).

Perhaps getting some cams would help... provided you don't mind revs, that is.

Get a job when you finish uni and get a turbo (like I did). Till then, save your money, and enjoy your lightweight NA car
