Rb25?

[traitorjack]

Im new here..Anybody know how much does it cost for rb25 det halfcut?
and any tips guys,coz maybe i want to implant the rb25 into my future 260z.

 

[bvalve]

above rm5k up to rm10k also got

 

[moonbiker]

I'd recommend this kedai potong - Look for Abang Sudirman. Last time he told me RB25DET engine for RM5.5K. All the best!

uhm...RB25 got a lot variety of range from the neo series to the normal older non-neo series, the older models will cost around RM3500-4500 nowadays, the neo series will definitely be more than RM4500 (but if u know ppl, then can get good price one, one of my friend's friend bought a neo series engine just RM3800 only, forgot which halfcut shop already)

 

[traitorjack]

Owh i see..thanx alo t for the info guys,..ermmm what are the diffrent between the neo and non-neo? both of them are turbo charge is it? and is it advisable to swap an rb engine into Z?

 

[stormlcc]

neo is something like variable valve timing (vtec, vvti and such), it's turbo of course, if it's a 260z or 280z, it can be done very easy

 

[traitorjack]

Owh...sifu sifu Stormlcc,..what monster you drivin right now?

so its mean that the engine mounting for 260z is ngam with rb 25?

since its is a fr, how about the long shaft? is it also can easyly fit?

Brother, pls be note Neo is same theory with Vtec, but, TOTALLY different with vvti... N Vtec, vvTi, Mivec is 3 different technic! :regular_smile:

 

[traitorjack]

Care to explain mohalw?oz i hav no exprieance in engine or modd..

but i do love them..

 

[stormlcc]

yes, care to explain what's the difference? I mean vtec, vvti, and mivec is basically the same in simple terms - electronic control variable valve timing, but in specific details, they are totally different, I only understand how vtec functions, but i'm not familiar with details on vvti and mivec

traitorjack, i'm driving A31 cefiro now, not actually very powerful lah, ok only...
i think the mounting on the 260z or 280z have to mod a bit to fit the RB engines, u have to ask your foreman to make sure, 'cause i haven't actually own any of these cars, no experience whatsoever on them

VTEC (standing for Variable valve Timing and lift Electronic Control) is a system developed by the car manufacturer Honda to improve the combustion efficiency of its internal combustion engines throughout the RPM range



MIVEC (Mitsubishi Innovative Valve-timing-and-lift Electronic Control) is an automobile variable valve timing technology developed by Mitsubishi. MIVEC varies the lift of valves by using two different camshaft profiles. It is similar to Honda's VTEC system.

VVT-i

VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota. The Toyota VVT-i system replaces the Toyota VVT offered starting in 1991 on the 4A-GE 20-Valve engine. The VVT system is a 2-stage hydraulically controlled cam phasing system.


VVTL-i

In 1998, Toyota started offering a new technology, VVTL-i, which can alter valve lift (and duration) as well as valve timing. In the case of the 16 valve 2ZZ-GE, the engine has 2 camshafts, one operating intake valves and one operating exhaust valves. Each camshaft has two lobes per cylinder, one low rpm lobe and one high rpm, high lift, long duration lobe. Each cylinder has two intake valves and two exhaust valves. Each set of two valves are controlled by one rocker arm, which is operated by the camshaft. Each rocker arm has a slipper follower mounted to the rocker arm with a spring, allowing the slipper follower to move up and down with the high lobe with out affecting the rocker arm. When the engine is operating below 6000 rpm, the low lobe is operating the rocker arm and thus the valves. When the engine is operating above 6000 rpm, the ECU activates an oil pressure switch which pushes a sliding pin under the slipper follower on each rocker arm. This in effect, switches to the high lobe causing high lift and longer duration.


So, is that enough clear?? :regular_smile:

 

[traitorjack]

Yo Stormlcc.... since that you mention about rb 25 neo...is it still from the skykine model? and if its yeah,from which series yea bro? is it from the r34 gtst?

bro mohalw.... haha,,its a nice info there bro,..too much of info and damn i like it.

 

[stormlcc]

neo can be found in both the R33 and the R34 model (Gt-t, Gt-s, and Gt-R)

Vtec also has the hydraulically controlled cam controlling the intake and exhaust valves, only VVTL-i has different functions with vtec, the new i-vtec is similar to VVTL-i

 

[V-Spec]

NEO only on R34.

 

[cmng]

NEO.. is only mean
Nissan Environment Oriented
nothing special


NEO have been in market 1997.. before R34 series
it applicable on SR16VE and SR20VE as well

 

[traitorjack]

hoho...too much input... which one? well anyway we all in da same group aite guys?

Looks like we got it all wrong here, except CMNG (he's the real expert on the RB series)

The 2.5L RB25 engine was produced in three forms:

• RB25DE - twin-cam (190 to 200hp)
• RB25DET - twin-cam turbo (245 to 250hp)
• NEO RB25DET - twin-cam turbo (280hp)

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.
In May 1998 a NEO head was fitted. This was also a low emission vehicle engine (LEV). The non-VCT and non-turbo was fitted to the R32 Skyline, the VCT turbo and non-turbo was fitted to R33 Skylines and Stageas. R34 Skylines also use these engines, but they are fitted with a NEO head.

Nissan Ecology Oriented Variable Valve Lift and Timing (commonly known as VVL) is an automobile variable valve timing technology developed by Nissan. VVL varies the timing, duration, and lift of valves by using hydraulic pressure switch between two different sets of camshaft lobes. It functions similarly to Honda's VTEC system.
The SR20VE is the most common engine with NEO VVL. There have been two main versions of this engine. The first version made 187hp and 145lb/ft torque. This engine was used by Nissan from 1997 to 2001. It is found in the Nissan Primera, Nissan Bluebird, and the Nissan Wingroad.
The second variant of the SR20VE is found only in the 2001 and up, P12 Nissan Primera. This verion of the SR20VE makes 204hp, and 152lb/ft torque. This engine is commonly known as the SR20VE '20V'. Although, in automotive terms, '20V' would normally be interpreted as having twenty valves, this is incorrect. The name '20V' is the name of the trim level of the Nissan Primera that it is found in. It is also a shortened version of the name SR20VE. This engine has 16 valves like the rest of the SR20 engines. This newer '20V' engine, is the only SR20 engine to get a restyled valve cover. It also has an upgraded intake manifold, which has longer runners and a larger 70mm throttle body (earlier SR20VE has 60mm).
Another version of the VVL SR engines, is the SR16VE. Although this engine has 1.6L of displacement, it has more aggressive camshaft specifications. It manages to make 173hp. The camshafts from this engine are considered to be an upgrade for SR20VE owners.
From 1997 to 1998, Nissan produced 500 limited edition SR16VE N1 engines. These engines made 197hp. They had further upgraded camshafts, and an upgraded intake manifold, and larger 70mm throttle body. These engines were found in the limited edition Nissan Pulsar VZ-R N1. They sold in Japan, Australia, New Zealand, and the UK.
One difference from Honda's VTEC system, is that NEO VVL engages the change of intake and exhaust cams independently. On the SR20VE the intake camshaft is switched at 5000rpm, and the exhaust at 6500rpm. However this trait was not included on the newer '20v' version, as both camshafts engage at the same RPM.

Engines That Have Neo VVL

• SR16VE
• SR20VE
• SR20VET

Currently, this technology is only available in the Japanese Market. However, many Nissan enthusiasts import this engine for swap.

[minghoo]

all sifu, im new here. can i ask how much is the total cost of transplate for rb20det? i heard tat got few type of rb engine. is tat have lot different between the engine? which one is better?
ohya.. wana ask did u all have any recommended workshop who do the transplate job? i m currently driving cefiro a31. 10s

 

[stormlcc]

Cefiro a31 10s???? 10 second ah???

anyway transplanting of RB20det cost around RM2000 for the halfcut and RM1500 for the worksmanship, not including timing belt, engine oil etc etc...

lol stormlcc, nice introducing bout Neo VVL engine series.... btw, the meaning of 10s = thanks....
