i was just wondering whether anyone could tell me what type of oil fitting if on the block side of the turbo oil feed line. Im just wondering because im soon to be putting on a different turbo on my 33 and want to replace the oil feed line with a full braided line. I want to make up the line before i take the original off the car, because i am limited for garage time. I work with hydrolics at work so as soon as i know the type of fitting on the block side i can order in the fitting and make the line up. Any help is much appreciated

You are after thread sizes and bolt length ? ^R33_KRAZY

There is a Banjo bolt in the block and a straight pipe feed return line that clamps on.

Just have the braided line made up to suit both banjo bolts on the block and on the top of the turbo oil feed line.

If you want any further guidance just shoot me a pm and i will send you a picture to help :P

Ok as promised.

The Oil feed Banjo bolt hole on the block is has a thread of 12x1.25

Same as the oil feed on the top of the turbo.

Water threaded holes on the turbo are both 18x1.5

Water threaded hole on the block is 13x1.5

Oil lines are quite easy , we used to buy -4AN mild steel weld on fittings drill them to size and braze them to a short section of the original steel pipe at either end . Then its straightforward to make up braided line with female -4AN fittings and join it all up . Have to support the line properly off metalic things .

      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.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      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
