Hi all, am building my rb26/30 as you can read in this thread: http://www.skylinesaustralia.com/forums/topic/374072-your-thoughts-my-rb2630-build/

I am going to go with a gtx 3582 t4 1.06 twin scroll rear

And most likely a rb26 6 boost manifold however:

The person i am going to get to tune the car reckons that a single 60mm tial wastegate will be the best option for this setup. However on the net alot of peoples thoughts seem to be that twin 38mm wastegates will spool it up faster.

So what are your thoughts on twin scroll with single vs dual wastegates?

also need to know what is the best cheapest valve springs to use with standard rb26 cams, as the same tuner says he has seen float in standard at around 20 psi.

he said supertech?

the place my head is getting reco'd at said to use a spool rear head drain kit, and im going to use a 1.25 mm restrictor and blocked rear

however; they seem to think that drilling out the oil return 1mm bigger is a waste of time, same with machining around the return

am going to be using a jun oil pump.

any opinion and thoughts are much appreciated :)

cheers, Chris.

      People still have Skylines? I thought they're non-existent now.

      Harness update time have had great fun and learnt so much already so far with this project. I started off making both the ignition and injector sub harnesses in the hope any mistakes i made here aren't as hard to undo and learn from as the main harness.  A cool comparison of the old harness using presumably TXL wire and the new which is using Tezel. Also opted to use DTM plugs to keep the whole setup as neat and tidy as possible and tucked the wiring under the coil bracket to try and keep it all from sticking out too much. Although the injector harness, I'm not overly happy with as I'm still using the rubber boots that are supplied with the type of plugs it just looks ugly and sticks out like a sore thumb with the white identifiers so a slight redesign may be done.   Then it was main harness time and most importantly trying to route it nice and away from the heat it will use the OEM heater hose routing which is no longer present to keep the harness up high and secure. it's amazing how much smaller this harness is able to be compared to the old one. plugged everything into the emtron and with the help of the tuner again attempted to start it up and instantly fired up and running smoothly on all 6 which was a big shock to myself. So still some routing and adjusting to be done for the final fit up and installing a knock sensor harness plug which is in the post all has gone surprisingly well.     The old harness for shits and giggles.

      They do that at random every now and then, with almost no detectable cause. Mine has done it a couple of times (over 25 years!!). Never worked out why.

      I don't post on here and have been lurking for some time now. Many of the topics have helped me out more times than i can count. I was racing yesterday (11/9) and blew a front right CV shaft. I have spares so I popped a new one in. A thread i read previously said to check the engine mounts if you blow a front CV. Upon inspection, the front right mount was completely separated from the upper plate. This discovery saved me time and money, because i would have blown another CV if i went back out. Just wanted to thank you guys and wish everyone luck with with their builds. (Now if we could only come up with a solution for my power steering belt flying off after hitting the rev limiter, lol)

      Either way he still need those style of spacer to go into the manifold because the photo he currently has is not going to work
