Hi Guys

I've been thinking about building a RB26dett and putting it into my 33, although i have a few questions regarding it.

1.Since ill be keeping it RWD would my current RB25det box bolt up to the 26dett without an adapter plate? also would the tailshaft need to be a different length?

2.Could i place a R32 RB26 in a R33? or would it be best to keep to the same model (r33) so the loom is quite similar?

3.Am i looking at a good power differance compared to the 25?

4.Will it drop straight in? (engine mounts different?)

I did try and search but i couldnt seem to find what i needed answered.

hopefully someone has done this and kept it RWD,

Thanks for the help guys/gals

Richard

There is a bloke in Townsville that has done this conversion.... You can find him on Qld street scene (www.queenslandstreetscene.com) and his user name is RB25_forever.

He'll be more than happy to answer any questions that you have :)

Ask Marty what it ended up costing him aswell lol. I don't see the cost benefit. The amount of money that conversion cost him could have had a fully built RB30/26 or RB30/25 with what ever turbo selection you wanted, instead of a 220rwkw stock internal RB26 that ended up letting go.

It all comes down to what work you could do yourself, if you could do everything yourself (engine out, engine in, wiring new loom etc) than it wouldn't be too bad.

Just the cost of the engine, ECU, sump modifications, wiring harness, exhaust modifications, intercooler piping, mod plate etc. I would do the clutch, engine mounts, fuel pump and a couple of other things while i was at it.

It all adds up. All the little things that you don't think of start costing a bit. Trust me on that one.

i have done a 26 conversion to my 32, it might help with ya 33

i guess you know you will have to get the 26 sump modified for rwd

you might have to change ya engine mounts on the 26 with ya GTS-t ones

with wiring you will prob have to wire in a resistor pack for the injectors thats with the 26 wiring loom

you will get around the 300wrhp+ on a stock 26

Anyone have any specifics? I have a 26 with loom im trying to power up. As i don't have the factory body loom i need a bit of info

I'm just trying to power up everything properly.. do i just run positive to the 2 relays near ecu or do i run it to the plug on the driver strut tower?

Is it an R33 RB26 loom you are using? Do you have a series 1 or 2 R33?

Ive got an r32 loom going into a race car with no loom whatsoever. Ive so far sorted out the power feed for the resistor pack and found the injector feeds in one of the big plugs on what i assume is the passenger guard part of the loom near the afms.

I'm sure you must be able to just run one or two power feeds to the loom somewhere on these plugs but i can't trace where. not having seen the original car makes things a bit tricky.

      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.
