Seems like i will need to spend bucket loads to a car that is still not as quick as my XR6T. Not really a fair comparison i guess given differences is engine capacity and turbo size.

For my 2cents it seems a bit redundant, what would be the benefit of me spending more on the R33 to get 300kw then i have to get 350kw out of my XR?????

Its like comparing apples to oranges mate. XR6T is in a whole different class. 350rwkw out of a XR6T would still not be as fast as a 250rwkw GTST around mallala. If your going for outright speed and power then modding the XR6T off its head is where i would be going but if it is going quick around mallala then GTST is where my $$ would be going.

You have to decide what you want out of both of your cars mate. In the end you would prob make 350rwkw out of your XR6T and drive happily not really worrying about coping a defect as well.

Hence why I chose an EVO X over and F6 Krishy.

If we had a drag strip though, F6 would be my first choice..........just upping the boost on those babies will give you close to 400 kw at the crank :D

So when has either an XR6T or R33GTS-t been fast around Mallala?......

I must have blinked and missed it :down:

Having said that a couple of years back in the Manufacturers championship David Ryan had a near stock (as they all are in that class) XR6T that we supplied a tune for, ran some - very - nice numbers at the Creek etc won a lot of races and I believe the championship. Should have been in the 1:17 slot or on that pace at Mallala so dont discount anything if it has the right setup and driver ;)

I thought malala was just some donkey track in a paddock in regional sa lol last time i went ardound it on my R1 i thought it was a motocross track lol just jokes

as mentioned, both cars are very different in dirveability, the way they put the power down and generally well... everything.

really depends on what you want it for and how you set it up. the last part is key, set up.

if you spend money on a bunch of parts to make a magical figure and only focus on that, then yeh it probably will be "fast" but doesnt mean it will be reliable, responsive, offer a great deal of feedback or be very driveable overall.

hey put it this way, know of a certain 380awkw gtr, the guys spent all his money on the engine, chucked in some second hand jap coilovers and called it a day. My gtst with just under 200rwkw and a massive flat spot in the power curve getting there shat all over it through the twisties.

in a straight line theres no comparison... 380awkw will eat almost anything else on the road.

my point being, two cars set up for two different things.

Could be a couple of reasons.

1. He wasn't trying

2. Driver ability

3. He wasn't trying and you were

Either way i find it hard to believe that a Gtst at 200rwkw (even with all the fruit suspension/tyre wise)would even come close to a 380rwkw at all 4 GTR (even with stock suspension) if both drivers are on par for ability and experience in the twisties up in our awsome hills.

I'm no expert but i can tell how much quicker my Gtst is at 350rwkw than it was at 200rwkw through the twisty stuff, then throw the GTR into the mix and theres alot more potential for speed.

Yes driver ability does come in to play, considerably too at times, but having a laggy setup versus a stockish responsive setup also has its perks. Suspension setup is also a crucial element when taking cornering ability in to play. Gtr being awd or not, with just a set of coilovers in it does not mean it will handle better than a standard factory set up. It comes down to alignment, both static and dynamic, stiffness, rebound, and overall coilover setup matched to the road conditions, tyres and power output of the engine, and more importantly the way the power is delivered... and a lot more of where that comes from.

Im not saying im keiichi tsuchiya by any means, far from it (i tend to stack in to things often) but I do spend my time figuring out how to make the most out of my suspension and i do occasionally really push my car when i can, am alone and is safe to.

The above post had nothing to do with me measuring my dick against everyone else etc. i do apologize if it comes across that way, there is too many variables as to why it happened. I was merely trying to put a point out there about different car setups delivering different outcomes. :D

      PRP RB26 cast block + head prototype running

      By GTSBoy · Posted

      Well, yeah, the RB26 is definitely that far off the mark. From a pure technology point of view it is closer to the engines of the 60s than it is to the engines of the last 10 years. There is absolutely nothing special about an RB26 that wasn't present in engines going all the way back to the 60s, except probably the four valve head. The bottom end is just bog standard Japanese stuff. The head is nothing special. Celicas in the 70s were the same thing, in 4cyl 2 valve form. The ITBs are nothing special when you consider that the same Celicas had twin Solexes on them, and so had throttle plates in the exact same place. There's no variable valve timing, no variable inlet manifold, which even other RBs had either before the 26 came out or shortly afterward. The ECU is pretty rude and crude. The only things it has going for it are that the physical structure was pretty bloody tough for a mass produced engine, the twin-turbos and ITBs made for a bit of uniqueness against the competition (and even Toyota were ahead on the twin turbs thing, weren't they?) and the electronic controls and measuring devices (ie, AFMs, CAS, etc) were good enough to make it run well. Oh, and it sounds better than almost anything else, ever. The VR38 is absolutely halfway between the RB generation and the current generation, so it definitely has a massive increase in the sophistication of the electronics, allowing for a lot more dynamic optimisation of mapping. Then there's things like metal treatments and other coatings on things, adoption of variable cam stuff, and a bunch of other little improvements that mean it has to be a better thing than the RB26. But I otherwise agree with you that it is approximately the same thing as a 26. But, skip forward another 10 years from that engine and then the things that I mentioned in previous post come out to play. High compression, massively sophisticated computers, direct injection, clever measuring sensors, etc etc. They are the real difference between trying to make big power with a 26 and trying to make big power with a S/B50/54 (or whatever the preferred BMW engine of the week is).

      Is the RB26 actually that far off the mark? Honestly from where I'm sitting a VR38DETT is not actually that much more advanced than the RB26. Yes, there is a scavenge pump on the VR38, it's smarter in a number of ways but it's not actually jumping out to me as alien technology. Something like a B58 or V35A-FTS on the other hand has so many surprising little design features that add up to be something that just isn't comparable.
