Thanks gents.. the manifold really is a very nice thing to look at.

Mr Baron - yes full race manifold. Geoff talked me into an 88-75 with 1.00ar rear, it will be replaced by an efr down the track once they're 'sorted' and available (there was a lot of negativity around the time I ordered so I thought I'd bide my time!).

Great stuff... interested in seeing the results.

cool. the 88-75 should be pretty good. it's still a 2.6 yeah?

It will be going on an rb30 bottom end. I spent a bit of time talking it over with Geoff and he convinced me the 83-75 is perfect on an rb26 but too small on a 30. We will see I guess!

Have you by any chance test fitted the manifold on the engine in the bay? How would it go for room running the ext gates with how the inlet pipes are sitting now?

I've only trial fitted the manifold using a gt35 on the old rb26 (pics at the bottom of the first page) - the manifold fouled on the steel hr engine mounts but the extra deck height on the rb30 should clear that up. The front gate sits pretty close to the strut tower and the gate plumbing is going to be interesting. The inlet and ic pipes shouldn't be an issue though.

Hey Corey - a good mate lent me his spare 26/30 to trial fit various bit's and pieces so I can answer you now. The manifold places the turbo higher than the motor, I have only a few mm clearance between the bonnet and comp cover (less than I have btw the motor and bonnet). The front waste gate sits pretty close to the strut tower as well. As mentioned before the gate plumbing will be fun.

Few more pictures/updates given there isn't much real progress :P

Was disappointed to find the ati balancer fouls on the radiator when the pump drive is fitted so it's for sale and will be replaced by a custom (shorter) balancer. Hopefully the Ross alternative is as good as the ati...

Still waiting on the new head from Brad, it's coming together with a big single pump which should be a lower risk option than running a couple 044's in parallel.

Sound deadening is all gone, rebuilt and powder coated the pedal assembies & now in the middle of putting it back together. Turns out hr's come with n1 spec brake booster so it's off for a rebuild.

Dummied up the rail and 1600cc injectors on the old motor to check fitment.

That is a nice tight fit. Looks awesome sitting in there though. I have a 31 sitting next my 32 at home will have to take some measurements the fullrace mani is absolute porn.

    • Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.
    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
