I have a set of ti rods but if i did not i would probably be going with these trick titanium rods..for the price i dont think they can be beaten , cheaper than pauter or pankl and still have exceptional quality and finish.

http://www.tricktita...connecting-rods

Now i just wish DART would manufacture an aftermarket tall deck RB based block that could be taken out to 91mm with .250 cylinder wall thickness.

I mean if they already produce a stronger aftermarket honda block then surely to god they can do an almighty RB26 based block.

http://www.dartheads.com/

At the same time if they would take the SR20VE vvl head design and apply the same technology to a absolute killer RB head .

Mmmmm ...my ultimate would be 91mm bore & 91mm stroke = 3.55L RB35VETT , now just give me a variable valve timing & variable valve lift (same as v-tec) mega head, with a pair of borg warner efr's.

Ohh i think a hollinger would have to be on the cards to cope with the above combolaugh.gif

We,ve seen some mighty impressive builds over the years on these forums but to my mind I dont think we've seen how good it can get yet. In conversation with my builder and tuner the other day I came

I'm not going to debate the merits or otherwise of the quick spool valve here, there is a thread on it already, Suffice to say I like the idea but to each his own. You are correct in your 25 v 26 hea

If i were going to go to that trouble I would throw the ford engine in the harbour and grab the nissan 4.8 with a brian crower stroker kit. Neither of them address the thread topic however. Its abou

At 400+ grams those Trick rods are fairly heavy.

I picked up a big block Ti rod once and i thought it was made of plastic it was that light!

Im pretty sure an RB30 Ti rod is under 300grams. I will need someone to confirm though *cough*

My Ultimate engine combo keeps changing every time i read this thread now :)

See my post re Bullet's Billet block.

the problem with a tall deck mega strong cast iron block would be the massive weight increse.

DART's 9.2" Deck "clevor" block is something like 30-40kgs heavier than a standard Cleveland block and around 20kgs heavier than Fords Nascar cleveland block and thats at standard deck height the 9.5" deck blocks are heavier again.

But if they did do a 91mm bore block I would run something silly like a 65mm stroke crank, super light rods and pistons and spin the bitch to 12,000+rpm using a large port billet 5 valve head.

I just finished porting a p12 20v head for a sr20

Went to the dyno it made 400 at the wheels at 8800

Turbo was to small but it didnt stop pulling till after 9

i watched a documentary on the bugatti veyron - that is a beast & a real marvel at cutting technology

titanium rods, w16 with 2 banks, 10 radiators, 20k to change tyres lol - sorry off topic but that engine would have to qualify as the best imo quad turbo

back onto rb's :)

-10's are fantastic, so is the rips racing sump kit!

I've been thinking about this a fair bit lately aswell. Well since I bought my car 2 years ago lol. Anyway at the moment I think mine would look something like this

- 26/30

- Nitto 3.2 stroker kit

- HKS V-Cam for inlet side. Not sure what people do on exhaust side when running V-Cam

- Full Race twinscroll manifold

- BorgWarner EFR Series turbo. 7670 i think it's called. Good for 700hp.

- Dry Sump

- Hollinger

mmm one day...

Its about RB engines, You know, the ones that actually bolt in to skylines.

RB48 stroker...that would be nuts. You could run a T70 or T88 on that. Anyone put the 4.8 into a skyline?

What Defines an RB ?

Are we talking OEM Head and Cylinder Castings ?

Stock Displacement ?

We need scope before you can really start spending imaginary money !

I took it as RB block and head. Whatever you do to it is fair game?

If I recall correctly they are in the 11k region. Twas posted up a while ago and someone got in contact with them re cost. Pretty expensive but if we're talking the ultimate RB then surely that has to be included.

They should have used their smarts and built a billet 30 block that would bolt directly to the gtr sump....Winnah!

You need to put liners in the alloy block anyway so may as well make a spacer and re-create a high deck but over 3L displacement.

Thats the RB48DET in action. Modified 4.8 litre with turbo setup. Patrol trucks running 12 second quarters up hill. That is the ultimate RB. Just pop that in a GTR - invincible.

Sadly it isnt an rb. Have you seen one in the flesh, they stand about 150/200 mil taller than the good old rb engine. Would be a bear to fit in a skyline.

In saying that it could probably be done. I ran in to a guy with an xr6 turbo ford engine in a 33 a while back. They are a big engine too. Bonnet mods required.

      R33 Fuel Pump & Brakes after alarm swap

      By GTSBoy · Posted

      Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.

      @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html

      These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.

      The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.

      It's amazing how well the works on the leather seats. Looks mint. Looking forward to see how you go with the wheels. They do suit the car! Gutter rash is easy to fix, but I'm curious about getting the colour done.
