hey guys,

Need to borrow a bit of knowledge from some RB experts :) . Over the last few months in my spare time ive been building up a 4WD RB25det for my R32 GTS4. I have installed a greddy type front feed plenum and its made things a little extra confusing for me now that i need to connect all the water lines.

in this picture you can see the turbo water line coming around the back of the head. I am using one from an RB20det, notice it splits into too lines. I'm unsure if i need both the lines now that im using the greddy, so im guessing i might end up blocking the top one off? For now, you can see i have connected the bottom line to the closest connection, just for science. Anyone know where it/they are supposed to go?

PICTURE 1:

in this picture you can see another part that needs connecting... any clues?

PICTURE 2:

in this picture you can see the last 3 water connections i need to complete... the green plastic one and the other 2 metal ones. I have blocked off the small top metal one as instructed by this tutorial from strich9. this leaves me with another 2 lines i need to connect...

2nd pic and last pic big fitting are heater hoses. Green plastic one isnt a water connection, its the knock sensor

thanx, i cant remember where to join the knock sensor then? also im guessing to join the heater hoses its going to be a little different than normal due to the fact its goin in a 32.

And the first pic, needs to go into the back of ur intake.

Mine actually doesnt have a T peice. its just a straight pipe, form the intake around the back to the turbo.

Probably would be better to do it this way, as the heater has flow from either side of the block. With the T peice you are just tapping the heater system into the turbos watercooling system.

yes this is what i suspected. If the rb25's only have one line then im sweet to block of that top one. cheers

connect that large one back to the water/oil cooler.

As Adriano said green one = knock sensor

not sure which large one your talking about?

i cant connect my turbo water line to the intake as the greddy doesnt have anywhere for me to connect it. on this tutorial it isnt very clear but it appears he has tapped the turbo water line into the small nipple on the heater hose connection? i assume this would be ok as the water would be the same temperature all around the block? or is there a cooler source of water i can tap into?

Remember this below? It's the turbo water line that went into the back of the stocker plenum! (yes, we gotta hook it up!)

Use our bit of fuel line, and some ingenuity, and extend the water line to the nipple below. You'll see what I mean. It's hiding.

Hi mate, yea you could probably get away with it. possibly check with someone whos done it, or someone more experienced to be sure.

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
