Hey, just putting my car back togeather with my rb30 and gonna remove the heater hoses as I live in a very hot climate and have never used it. The positives are not having random leaks in hard to get to places. My turbo is also not water cooled. Freddy manifold. So the question is.. Do I cap the two heater hose outlets or do I join them up? Ones on the back of the block and ones where the water pump is.. U guys know the ones.

I need to keep one of the smaller ones that tees of at the back of the block and rais it above the head for a air bleeder. At least that's how I had it originally and it worked a treat. An I never had any over heating problems.

Also. I have a what I would call a mint condition rb25det bottom end that i want to go to a good home for free. All u have to pay is freight from

post code 6725. I can provide photos 175000kms

Hi Ruth.

I just joined my two water outlets and have never had an issue with high temps. It was hard to find info on blocking or joining them I found so I just went and joined them. I do run a water cooled turbo though so I just got a -6 fitting welded to the rear heater hose line. That way I can still have water feed but no chance of leaks using braided hose :)

I didn't incorporate a bleeder into my setup either, I just park car on a hill and use an extension on my radiator cap to make it the highest part of the system to bleed it and it seems to work a treat.

Let me know what you end up doing :)

Thanks heaps for that mate. I'll do as u do, join them but I'll leave my bleeder at the rear of the block raised to where the clutch master cylinder is. That way if I go water cooled turbo I've got a feed ready to go.

By the way u know the heater feed behind the water pump that is pressed in? I've bashed it out from the front when I had the pump of to clean it up as it was a little rusty and I've deleted the little t piece that comes off to eliminate more hose clamps. What I was wondering was do they just bash back in with a rubber hammer with some sealant like silicone or jbweld?

I'm not sure what to do. I could tap a thread there and use somthing like a barb or an10. Don't really want to tho.

I'm not sure, I did the same as you and cut one of the barbs off and just use the single barb now. I know the rear one screws into the block but not sure about the front as I never removed it.

I don't think silicone would hold it back in if it's loose. If it's still an interference fit then a little sealant would be fine I would think.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
