long story short guys i have a S2 R33 and i have no choice but to replace all the water hoses under the intake plenum. why might you ask.... when my second hand motor was fitted on of the hoses under the plenum didn't have a clamp on it which caused coolant to get sprayed over the the other hose and caused them to turn to utter shite bla bla bla. the problem i am face with now is that to replace the hoses i'm going to have to go genuine but some of the hoses are worth $70+. now i know the rb26 has a complete silicone water/heater hose replacement for around $300, is there such a kit for the 25 are there any other options.... any ideas guys

Thanks

And im pretty sure the GTR "kit" does not count the ones under the plenum etc etc.

For some of them you can just get away with generic hose.

I've replaced a couple under the plenum on my RB20 from years ago, just used cut-pieces of normal rad hose

sorry by generic are you guys referring to hoses with formed bends that you can cut to length. i think this is a pretty important topic as these motors are getting pretty old and these hoses are bound to go pop one day.

Thanks guys i'l post up a picture of what my block look like thanks to a very small coolant leak from one of these hoses.

just a quick note i got my call from Nissan and the cost for 6 hoses is just on 400 and i require another that they are sourcing.

I would imagine that if you search you will find my fairly detailed reply about me doing EXACTLY this about 1 month ago - also linked to NISSAN diagrams with all hoses under the plenum with part numbers. And description of what generic hoses I used.

Generic hose will fit most, but you will need the heater hoses both in and out from Nissan ~$30 each + you will also need a 120° bend of I think 3/8" - this can be cut from a multi-fit at your local Repco (or genuine). The rest is generic - you might want to get the 4-way metal joiner new also, likely to be farked.

I have a lot of these genuine hoses in good condition due to doing a greddy-style plenum swap. If you are interested & can take photos of what you need, PM me with pics. Will check if I have what you need...

      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!
