That was bound to happen considering it is a small turbo (especially hot side) for such a serious engine, same result with that other fella posting in the RB30 section.

I agree, I'm running a 6466 on my RB30 and I have not had the need to go over 6000rpm yet, on low boost. Turbo is well and truly whistling away by 2500rpm

Can't even imagine how ridiculous GTRNUR 3.3l is to drive

I was seeing about 5lb at 2000 rpm and 18lb aroudn 3400 before it was tuned properly, so it it would probaby be even better than that now. Although now with the 10lb gate springs springs the gates bleed little until max boost is reached so it will be a little more laggy. Something I hope to have remedied soon.

I'm ~5-700 later than you. 2000 and above you can feel the turbo working. Great combo IMO.

I'm impressed with mine,yours would/will be/is next level again

3L+ and the 6466 is a killer combo.. Here's what I was seeing during some early road tuning of my setup... 3.4L, 6466, 1.0AR

26psi, 3600rpm loading it in 4th... will make 5 - 6psi instantly in any gear if the revs are over 2000rpm.

Do you have issues with fuel overheating on long drives of 2hours plus?

I drove mine for 2.5hrs trips 4 times in one weekend a month or so back with a Magnafuel Protuner 625 running a -8 feed and standard return lines, was no issues with heat

    • Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice  
    • Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance
    • My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
    • The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.
    • Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
