Skylines has always been one of my passions. The look of the car, the engine as well as the whole experience of it just gave me an indescribable feeling of excitement. I'm sure many share the same feeling to Skylines especially the GT-Rs. I'm blessed on having a BNR32 as my weekend driver but it does not compare to a friend who not only have a similar BNR32, but with a slightly different engine under the hood.

BloodRed, another friend who also drives a Skyline had the chance to witness the tuning of the RB30 BNR32 beast, known among friends as Gorgon (it's black with a monstrous engine, so what would you expect? :biggrin:).

In his own words;

"The acceleration was astonishing. The exhilaration was a natural high. All the pain in my ear from the dyno run, all vanished. The elevated endorphin levels made sure of that."

I know for a fact that some RB30 blocks have been going around our dear BolehLand to be put into cars ranging from Skylines to Cefiros.

Basically the RB30 block is a tad higher than the normal RB25/26 and was used in Holdens as well as finding their way into Nissan R31s as well. It has long been said that there's no replacement for displacement hence the torque is higher than a similar tuned RB25/26.

Here's another excerpt from the Gorgon experience;

"Then suddenly, right out of nowhere, this surge of lateral gravitational force was pulling me back and wedging me into the tiny R32 GTR seats, jolting me back to life as I struggled to make sense of the ferocity of the T04R turbine that was spooling rapidly on boost hitting the 1.2 mark on the orange HKS meter within seconds... no... milliseconds! My God, that was a devastating yet amazingly pleasurable wake up call I've ever had in my life."

Men and their big engines. What's not to like? :driver:

Back in the early time of childhood, I remember, in Ultraman Ace (the one that need 2 people; one men and one women, in order to transform) Gorgon is a monster from another planet trying to destroy earth .... Hakutotominami...!!~ :biggrin: monster indeeeeeed...

just to share, some history lesson...........

>RB30
Four models of 3.0 L RB30 were produced from 1987 - 1991:
RB30S - carburetted single-cam
RB30E - fuel-injected single-cam (114 kW @ 5200 rpm, 247 N·m (25.2 kgf·m) @ 3600 rpm)
RB30E R31 Skyline - fuel-injected single-cam (117 kW @ 5200 rpm, 252 N·m (25.2 kgf·m) @ 3600 rpm)
RB30ET VL Commodore - fuel-injected single-cam turbo (150 kW @ 5600 rpm, 296 N·m @ 3200 rpm)
This motor was produced for use in the Skylines, Patrols and rights bought by Holden because the Holden 202 (3.3 L) powering the Holden Commodore could no longer satisfy tightening emissions requirements, and with all new cars required to run on unleaded petrol by 1986, a quick replacement was needed. Nissan Motor Co. sold the RB30E to Holden for the VL Commodore. Because the radiator is fitted lower in relation for the engine in the VL, there is an increased likelihood of air locks forming in the (alloy) cylinder head, causing this to overheat and warp. This was less likely in the R31 Skyline as the radiator is mounted higher.[5] The engine proved to be very reliable apart from this issue. The RB30S was found in some Middle Eastern R31 Skylines and in some Nissan Patrols. The RB30E was found in R31 Skylines and VL Commodores in Australia as well as in South African R31 Skylines (with 126 kW @ 5000 rpm and 260 Nm @ 3500 rpm)

The turbocharged RB30ET (producing 150 kW) was found only in the VL Commodore (available in all models) and consisted of a lower compression RB30E bottom end, more powerful oil pump, T3 Garrett turbocharger, 250 cc injectors and a different intake manifold. The motor itself is still popular today (albeit in highly modified form) on the Australian Drag Racing circuit.

Nissan Special Vehicles Division Australia produced two limited models of R31 Skylines, the GTS1 and GTS2. These contained slightly more powerful RB30E engines, containing longer opening duration cams and better flowing exhausts.

GTS1 RB30E - injected single-cam (130 kW @ 5500 rpm, 255 Nm (26.0 kgf·m) @ 3500 rpm) - special cam profile, special exhaust[6]
GTS2 RB30E - injected single-cam (140 kW @ 5600 rpm, 270 N·m (27.5 kgf·m) @ 4400 rpm) - special cam profile, special exhaust, piggy back computer, valve porting[7]

RB30DE
These rare engines were used in the Tommy Kaira M30 based on the R31 Skyline GTS-R. A modified RB20DE head was bolted on to the RB30E block. It delivered 177 kW (240 PS) @ 7000 rpm and 294 N·m (30.0 kgf·m) @ 4800 rpm.

RB30DET
RB30DET - R31 RB30E block, R32 RB25DE head.Nissan did not produce this engine, but it refers to a turbocharged engine featuring an RB30E block with a twin-cam head conversion. Common hybrid in Australasia (referred to as the RB25/30 or RB26/30) using a RB30E bottom end mated to a RB25DE,RB25DET or RB26DETT cylinder head and turbo (RB20DE and DET heads are not used as the bores are different in size; RB30 86.0 mm RB20 78.0 mm but were originally modified and used on the Tommy Kaira RB30DE as the RB25 engine did not exist). The RB25DE cylinder head from the A31 Cefiro C33 Laurel or R32 skyline (aka: Non VCT) can be used, and fits perfectly on (although better valve springs are recommended, GT-R valve springs are a decent upgrade). The RB25DET (from the R33 Skyline or C34 Laurel or Stagea) head is also used, however an external oil feed must be fabricated for the variable cam timing (VCT) on the RB25DET, and the galleries at the front of the engine do not line up. The variable cam timing may be disconnected altogether.Also it is wise to change the oil restrictors in the block to 1.5mm and get a full face oil pump drive collar machined onto the crank(solves it shattering at high RPM) with the use of a twin cam oil pump.

The fitment of a twin cam head from any of these engines onto a standard compression RB30E bottom end gives an ideal compression ratio for a mild to moderately modified street turbo engine around 8.2:1, (but always check your compression when building this engine as it may vary), making the conversion popular amongst those who would otherwise convert their RB30E to a high compression RB30ET using original ET bolt on externals.

Although it has a larger displacement than the RB26DETT, maximum possible horsepower is less, as the RB30 block lacks the RB26 block's internal cast-in bracing, and consequently cannot rev as high due to harmonic issues at ~7500 rpm. To compensate, the RB30DET produces more torque at lower revs due to its longer stroke. However they have been known to reach engine speeds up to 11,000 rpm with a lot of balancing and the use of the RB26 head with solid lifters. Power of the RB30DET in this form can far exceed that of an RB26DETT, RB30DET's are usually only found in RWD cars as it's a lot easier to install, with the 4wd setup in the GTR or GTS4 an adapter plate has to be made to fit the 4WD sump as its bolt pattern is different to the RB30, as there is a adapter plate between the sump it sits off on the gearbox bolt holes, they will have to be modified to fit.

There is also an 'RB30DETT' kit manufactured by OS Giken of Japan, which bolts an extension on top of the RB26 engine block, and fits liners, to give an 86 mm bore x 86 mm stroke. It is available as an assembled short block, containing billet chrome-molybdenum crank, billet chrome-molybdenum H-beam connecting rods, forged pistons, and costs ¥1,500,000.

All due respect, there is a huge difference between what is available online regarding the theoretical limitations of the RB30 engine but there are people out there who would beg to differ. One being Robbie Ward of RIPS in NZ who is undoubtedly the world's expert on RB30s and has built countless of them with huge power, some capable of revs in excess of 10,000rpm on stock cranks and blocks yet none of his engines have actually failed. At least none due to errors on his part. Even the ones with stock internals are known to support over 600hp atw and the ones he uses to run 7sec 1/4 mile times have been doing so for many years without fail and have probably completed hundreds of passes at minimum.

Try visiting and GTROC UK forums and I'm sure you'll find lots of information there all verified by customers from all over the world or drop him an email, from experience he usually replies within 24 hours. Just didn't want anyone getting the wrong idea about RB30s and although WPQ800 meant well, anyone reading the above could get the wrong, unjustified impression of the RB30 and what its truly capable of.

Peace
:beer:

by the way i got my info from:
Nissan RB engine - Wikipedia, the free [email]encyclopedia@@AMEPARAM@@/wiki/File:RB20E_R31.jpg[/email]" class="image"><img alt="" src="http://upload.wikimedia.org/wikipedia/commons/thumb/a/ab/RB20E_R31.jpg/250px-RB20E_R31.jpg"@@AMEPARAM@@commons/thumb/a/ab/RB20E_R31.jpg/250px-RB20E_R31.jpg

heheheh FYI i dont even have a nissan, i drive a honda n alfa n proton, so i only learn from theories n books n articles n comments from experts n experienced ppl like u....... thanks anyway!

Whoa chill dude, I wasn't having a go at you. I was just adding that despite what is commonly available online on websites like Wikipedia, there are others out there who have pushed the boundaries and very successfully I may add.

I was merely referring anyone interested, yourself included to explore other sources of information one of which is GTROC UK where RIPS.NZ is a regular and shares much of what he has achieved with the RB30. No need to take it so negatively - I even began my post with "all due respect" and ended with "peace".

I'm far from an expert but at least I try read as much as I can and usually when people point me in the direction of where I can find more detailed and accurate knowledge, I'd definitely check it out.

Oh well.
