how do i unblock this????

can i blow it back with a air compressor to unblock?

can i hook the turbo and all other lines up and start the motor will this unblock itself and then hook it on the turbo? but 90% sure its the renturn water line so it wont do f**k all if thats the case......

Just jam a bit of coat hanger in the end until you get through the muck and then pump some water through the engine with the hose to flush it out properly before connecting to anything.

Better to get rid of it now. It's not a big issue, i had to do the same when going back to a water cooled turbo.

Tryed unblocking with metal wire only got so fare and wouldn't budge thinking bout on hooking both hoses and gettin the air conpresser onto it blow all the shit out

either that or buy a new hose

go online and buy a datsun L26 or L28 Oil filter stud.Basically you want to find one for the 240z or early 280z.

This will allow you to delete the oem oil cooler.

This is the Oil filter stud

You can install a greddy oil filter relocation kit or any sandwich plate to run your oil cooler.

It's best you shop for a aftermarket oil cooler

There are some cheap ones out there that work fine for the RB20/RB25.

This does requires to move and plug some of the water hoses.Nothing hard.

Super easy to do.

Not sure who is getting confused here but I think op means fitting in inlet manifold is blocked. The water tube Runs between the fuel rail and head but is part of the inlet manifold. The other end comes out behind number 1 injector.

IF he is refering to the tube thats running under the manifold it BOLTS onto the bottom of the inlet. . .he hasnt specified wether its a RB20 or RB25 (have taken it off my RB20 and blocked off feed from head)but they both bolt on, if that one is blocked up i would be suprised as they are of large internal diameter

i removed factory oil cooler off a R33RB25DET and used alloy oil filter block and pressure sender off a R32RB25DE, it bolts straight up. . . this enables me to use factory 32heater hoses/metal outlet-inlets on the 25 going into my 32

U guys are way off topic buddy it's the water line that runs to ur turbo and then runs behind the motor/ ontop of the gearbox bellhouseing into the plenum it's a water return line it's blocked tryed unblocking it today still wouldn't unblock im

Just gonna leave it blocked and run a t piece hose from the coolant lines that run through my throttle body so that way it can still flow back into the coolant system and when I pull the motor out and fix it then

      Lets say I wanted to buy this, specifically for this purpose. How do I actually perform the function. Can I still buy a Consult-1? Am I about to be burned by the fact my car is a 2000 model Series 2 R34 and thus will be some stupid other system? Do I just need this -> https://obd2australia.com.au/product/nissan-consult-14-pin-to-usb-ddl-diagnostic-interface-with-ftdi-ft232r-chip/ And with what software?

      That's probably OK. That's a face to face compression joint between two surfaces with the clamping load provided by those bolts. So.... it's unlikely that the bolts will end up feeling that load in shear, unless the clamping surfaces are not large enough, bolts not got enough tension on them, etc etc to prevent the two faces from moving wrt each other. Which... I would hope the designers have considered, seeing as it's probably one of the most important things the upright has to do apart from resist collapsing in its own right. But yes, it would definitely be worth asking them what their safety factor on that part of the design was. I tend to think that the casting, being a casting, is not necessarily the strongest bit of material in the world. It's about an inch square, and when you think about the loads that are being put into it, you have to wonder what safety factor the Nissan boys (and every other OEM engineer who has designed all the millions of other uprights that look essentially the same) used to account for defective casting, aging, severe impacts on the wheel, etc etc.

      Those bolts would be orders of magnitude stronger that cast aluminium though.  And its mainly clamping force, not shear they are dealing with?

      Except all that twisting force that is breaking a cast piece, appears to be going through 4 bolts in the picture Johnny posted of the BryPar one...

      R34 auto to manual conversion help

      By GTSBoy · Posted

      The smart approach is to use the gearbox loom from the manual car. Makes it a lot easier - just plugs into the switches on the box and plugs into the main loom up near the fusebox. Then you only need to deal with bypassing the inhibit switch. The other approach requires you to use the wiring diagram to identify those wires by colour and location, perhaps even indulging in a little multimeter action to trace them end to end to make sure, and then.... you will have the answers you need. The R34 wiring diagram is available on-line (no, I do not have a link to it myself - I would have to do a search if I wasn't able to go to the copy I have at home).
