So I Un-Turbo'd My R32 Gtst And Its Running Rich

[IM-32-FK]

You would find that the R32 also came stock rb25de. Therefore you will not need an engineers cirt.

LOL WUT read what you just wrote

Hmmm, you should watch what you are talking about. As for his suggestion of putting a proper non turbo motor in there is the smartest decision you will ever make.

As for why your car is running shit? Its because the turbo is missing doofus. And want to know another thing? Your non turbo'd car is still illegal for you to drive on your p's because it was registered as a turbo.

So instead of spitting in people's faces like a spoilt brat, just take what he says and reply in a manner as follows, no thank you, I would rather try something else

so he insults me, but i cant insult back?

[sydking]

Yes i did re read that? Not sure what your implying,

You mention you dont want to go Rb25de becuase you will have to pay thousands for a cirtificate,

I said, They came stock with the Rb25de in some year makes, Therefore there is nothing to engineer.

Mate, Were trying to help here... Chill out. its friday god dammit

which r32 skyline came with stock rb25de please tell me right now

The 2.5 L RB25 engine was produced in four forms:

• RB25DE - NON-TURBO twin-cam 140 kW/190 PS (180 - 200 hp ) @ 6000 rpm, 255 N·m (26.0 kgf·m) @ 4000 rpm)
  
• RB25DET - twin-cam TURBO (T3 Turbo) (245 to 250 hp and 319 N·m)
  
• NEO RB25DE- NON-TURBO twin-cam 147 kW/200 PS @ 6000 rpm, 255 N·m (26.0 kgf·m) @ 4000 rpm)
  
• NEO RB25DET - twin-cam TURBO (206 kW (280 PS) @ 6400 rpm, 362 N·m (37.0 kgf·m) @ 3200 rpm)
  

RB25DE and DET engines produced from August 1993 also featured NVCS (Nissan Variable Cam System) for the intake cam. This gave the new RB25DE more power and torque at lower rpm than the previous model. From 1995,(Series 2 Engines) both the RB25DE and RB25DET had a revised electrical system and the turbo charger on the RB25DET(s2) had a plastic compressor wheel rather than aluminium. The most obvious change to the system was the introduction of ignition coils with built in ignitors, therefore the coil ignitor that was on previous models was not used. Other changes were, different air flow meter, engine ecu, cam angle sensor and throttle position sensor. Mechanically series 1 and series 2 very similar, the only mechanical difference would be the Camshafts as the series 2 Cam Angle Sensor's shaft that goes into the Exhaust cam is slightly different. This is very important to not mistake!

In May 1998 a NEO head was fitted, which enabled the engine to be classified as a low emission vehicle (LEV) engine due to their lower fuel consumption and emission output. The NEO head featured solid lifters rather than hydraulic, revised camshafts, with on/off solenoid Variable VCT , used a hotter 82°c thermostat, model specific coil packs and a revised inlet manifold (the runner diameter is reduced from 50mm to 45mm to increase air velocity and low end torque) in particular the RB25DE NEO which had 2 inlets going into the inlet manifold. The combustion chamber of the head is smaller so GT-R spec connecting rods are used to compensate as well as model specific pistons. The turbo received the larger OP6 turbine which some came with steel compressor and turbine wheels, where others had the Nylon plastic compressor wheel and ceramic turbine wheel. Some also used an N1 type oil pump and had the oil pump drive collar on the crank revised to help cope with the breakage problems associated with fast, high revs. All in all they are quite a different engine in their own right - a culmination of 20 years of Nissan RB engine building rolled into one.

The non-VCT, non-turbo RB25DE was fitted to the R32 Skyline, the VCT turbo and non-turbo was fitted to R33 Skylines and the WC34 Stagea. Early R34 Skylines use the non NEO RB, later models use the NEO version.

Should have just bought an S-Chassis for cheap, plenty of manuals going around. Instead you went the route that 99% of

the people in this forum will be against. This will have been a hit in the wasteland.

SyDKing:

Your not telling me which exact model the rb25de came with in a r32. If i recall correctly, they were first used in the series 1 r33 skylines in 93. I dont think nissan ever put a rb25de into a r32 from factory.

So, are you trying to say i can swap motors between cars that use the same chassis?

Edited September 21, 2012 by IM-32-FK

[LayneGXE]

It came in some later R32 GTS models. As he said in his post.

You should research this stuff man, otherwise it'll cost you money and time, also make you look stupider than you actually are

Everyone here is giving great advice, grab an RB25DE about 1k?? Would just need it put in and that's all.

One thing you'll probably get pulled up on is having a turbo badged and registered car, cops will love you for that even though it doesn't have a turbo.

tl;dr: Yes you can put in rb25de and goodluck

[drunkn snail]

r32's came with the motors rb20det, rb26dett, rb20de and the rb25de. rb25de's are cheaps as chips, picked up a replacement motor for my blown r33 rb25de for $400, worked perfect ever since, guy even claimed it only had 67000 on it but i dont live in lala land and know that isnt true.

so if your smart and car work on cars yourself you can have a mad running r32 non tubro for around $500, which is wayyy cheaper than trying to fix up your unturboed rb25det-t.

Wowwww I thought you were trolling. Don't know how many more people you need to tell you that R32's DID come in RB25DE, but heres another one!

Seriously though RB25DE in the little 32 would go well!

Edit: Also I don't think you ever register your car as a Turbo... It definitely doesn't come up with Turbo or N/A in police computers when they rego check it. Unless the copper can read long engine numbers that pray-tell to the aspiration.

[Odium]

Which they won't look at unless they've popped your bonnet, in which case they'll definitely be getting you with your current modified manifolds etc.

[drunkn snail]

Also doesn't unturboing an engine require an engineers certificate anyways? Therefore making it illegal

[mad082]

and this is why i love the NA section.

the easiest and cheapest option is to simple buy a rb20DE to put in it. the best option is to put the rb25DE into it, and the worst, and most likely the most expensive option is to try and get your current engine to run properly.

actually the best option would be to sell it and buy something else. a SSS pulsar would be a better option. will be faster and cheaper on fuel, rego, insurance, etc. or even just a commodore or falcon, both of which will be faster, cheaper, etc.

[IM-32-FK]

I was under the impression that the only time you need an engineering cert is when you upgrade the motor and the difference between the fuel displacement (between the original and the new engine) is greater than 0.2L

but thank you all for the insight.

gearbox is gonna need changing too, so thats another $500 i guess...plus labour costs probably $600-$800...

it all adds up, i dont have that type of money now anyway it needs to get painted.

[zebra]

Gearbox?

[IM-32-FK]

Gearbox?

it doesnt need changing? they are compatible? i might just do this mod...let the paint job wait...

[WMDC35]

the gts25 r32 came with 25de, the rb20 with the turbo removed should've run not too bad, slow, but not running too terribly enough to bother someone that would do a -T, have you done the usual checks? put a turbo back on? even a stock 20 turbo

(i think zebra is asking why you think you need to change the gearbox?)

i dont know, you tell me. Can i use a rb20det gearbox with a rb25 engine?

[WMDC35]

yes

[mad082]

all RB boxes bolt up to every RB motor (including the RB30)
