RB25DE specs


Recommended Posts

my mate just bought a 96 gts (rb25de), i told him he's an idiot coz cud have gotten a gtst for an extra grand but he says he wants a full house gtr engine lol, so what are the specs of this engine? i know it makes around 130 - 147 kw

anyone know the stock 60ft and 1/4 mile times??

He shud race my gtst makes around 210rwkw which is ok considering havent spent more than 5 grand on the car.

So yeah how does it compare in the 60ft and 1/4 mile times? Anyone have some actual figures?

ok mate, firstly a gtst makes about 184KW stock :P

stats on the RB25DE:

RB25DE  

Bore & Stroke  

Capacity  

Power  

Compression  

Twin cam  

86 X 71.7  

2498  

190ps @5600  

23.5kg's @4800  

10 to 1  

   

The RB25DE is the middlebrother of the nissan RB series Its a Twin cam 2.5 liter.  

This engine is very torquey and is great if you don't require turbo performance.  

It features in the R23 R33 R34 series of Skylines both 4 door and 2 door and came in manual or automatic.  

also is came in the R33 & R34 gts-4 so that the gtr had no competion.  

don't quote me on 1/4 mile times, but I think it's about a second slower over the distance than a gtsts (both stock)

The RB25DE has some go - nice form a running start about 50k's and dropping back a gear...but it's never going to beat a 'worked' gtst - without spending money on it....allot of money :P

Some easy shit he can do:

Work on intake - high flow filter/POD filter

2.5" Exhaust (cat back or full system - just no larger then 2.5")

Extracters (check link in my sig for some cheap!)

NOS (he can get a nice wet kit for <900 bucks and run a 50HP shot)

Simply stuff ^^^

Then ofcourse he could spend 3500 bucks, buy a frontcut 33 and do a conversion - but if it's his first car - the relative savings on fuel/services/insurance/running costs will be great - they look nice and go ok - i'v beaten every homo VL driver whom tries to go 'fully sick' on the freeway - lol - also the older silvia's/180's have no chance....

your mate is not an idiot for buying an NA, and I would like to think that he knows what

he is doing.

Everyone always says forced induction is the way to go, of course for an extra grand or two

you definately get bang for buck... so why not.

I paid as much for my GTS as the cost of a GTST, for a COMPLETELY stock, clean, first owner,

etc car.

It comes down to your needs, and driving lifestyle. If your not racing, then why do you need

turbo? For a street driven car, for daily use - I find NA is the go.

Your mate might have his own reasons for buying an NA. Whether it be insurance, or

fuel consumption, whatever...

That said... gatty has pretty much summed up what can be done to NA engines.

I think the factory quoted figure is 147kw@4400RPM, I have recently put my car

on the dyno for a base figure, stock except for pod filter... I managed 108rwkw

Stock times are a bit hard to answer as alot depends on the driver and the strip in question specially when it comes to 60ft times. There are so many variables that come into play, I've seen a stock auto sedan 96 GTS25 do 16.8 and a stock 94 GTS25 coupe do 15.8 so if you say somewhere in the middle you should be about right. With a good driver you should get around 2.3 sec 60ft.

Hope thats of some help

    • Thank you for explaining. Makes more sense now. I saw that diagram but wasnt sure if the MAC solenoid would use the same plumbing. So I just did what the stock looked like. Ill get that fixed. As for MAP sensor, When I place vacuum line from MAP to stock location vac reference ( port by BOV flange ) the car runs like crap. I think the port is clogged or something, cause when I moved the MAP line to plenum and connected the BOV to that line, I get compressor surge. This is why I moved MAP vacuum line to plenum where BOV is. Where can I T the MAP vacuum? Sources Ive read said to let MAP vacuum be its own and not to T.
    • You've done it wrong. I don't have time right now to type up enough. I'll have to come back to it or maybe someone else will in the meantime. The boost signal has to pass through the MAC valve from boost source (turbo outlet - effectively anywhere between the turbo outlet and the throttle body will do, but closer to the turbo outlet is best) to the wastegate. What you have done is connected it sort of like the stock solenoid. But it doesn't work the same way as the stock solenoid. That Tee piece that you have connected the solenoid to....? The solenoid itself serves that function. You should look up a typical MAC valve connection diagram for a single turbo internal wastegate application. You'll find one easily enough. Every single boost controller manufacturer that uses MAC valves will have one. Bugger it, I'll just grab the HP Academy one. The other thing you have to get right is that the boost source has to be connected to the correct port on the solenoid valve. This is because the solenoid makes the valve switch from connecting 2 of the ports when it is unpowered, to connecting one of those first 2 ports to the third port when it is powered. One inlet, two outlets. You will note from the diagram that the common port is port 3, the port to the wastegate is port 2, and port 1 is the vent (where the boost signal escapes when the solenoid pulses ON). As to the BOV.... the vacuum signal for the BOV simply has to come from the plenum. It must register boost when you're on boost and vacuum when the throttle is closed. That's all. The original location on the plenum is best. Best practice is never to interfere with the vacuum line running to the FPR. Just leave that one alone, as you will avoid causing unintended problems that might occur if you mess something up.
    • I was able to complete installation of the G4X ecu. I needed to reroute MAP vacuum signal from stock location to where BOV is connected on the intake plenum. Has anyone needed to do the same? When I connect vac port by the BOV flange to my HKS BOV, it doesnt work and I get flutter. I would to get BOV working, where would it be best to T in? Or would it best for me to move MAP vac line and T into FPR? Secondly, I installed a MAC 3 port boost solenoid and wanted to know if i routed it correctly. I place two lines from stock boost solenoid and placed it on ports 1 and 2, leaving 3 vented. The T for wastegate and boost source on compressor elbow is on port 2, and port 1 is connected to turbo inlet intake pipe. Please see attached pictures. Ill upload ecu config later today. Thanks in advance.
    • some people are still around weirdly enough - most people just use facebook now to ask the same 12 questions tho XD  
    • Omg Rezz! Yep we're still here and actually seeing a trickle of oldies coming back.  How's things?
