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

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)

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 !!! ) :wave:

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 !! :wave:

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:

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 :huh:

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 :worship:

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

      The Evolution Of "night Fury"

      Mixing things up - installed some leather recaros to match the leather seat covered rear seats. Interior looks pretty schmick now except for some slight wear on the steering wheel which I will monitor and address if it becomes worse or actually noticeable!

      Unpeeling the Orange

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
