I suspect, for the money, you'd be far better off simply cleaning up the factory manifold than going the Brae side mount. The Brae one gives you all the bad things of not being factory (like defectability, having to move and change stuff) and nowhere near as big an improvement from std as any decent high or low mount would.

what about a low mount 6boost, obviously its not factory, but it would help to hide the turbo with some added heat shields and lots of stealth black.. Ive caved in and have ordered one to get every drop of response from the split pulse 3076, as the factory manifold has started to crack even after ceramic coating it before.

How much better is side mount one than the factory one ?

Also wouldn't it be an instant defect if you got caught with a high mounted GT3076R ?

A .

It made 40kws more then standard Based on a ATR43SS2 turbo.

I'm getting over the whole street legal thing. It just comes down to how you can fool a cop, obviously smart cops can tell from those cover ups while stupid ones will defect you for having an "stock intercooler" or having wholes (obviously stock cooler piping) on the chassis .

Plus you can't go to EPA without a stock manifold, turbo, and exhaust. So get your self a good high mount ex gate setup, quite exhaust, and enjoy the power while you can. lol

For Hypergear , does that Brae side mount manifold place the turbo pretty much where the Nissan cast one does if you spaced the turbo out for the T04S 0.70 comp housing ie GT3582R etc .

I also wonder if its possible to butcher a couple of std heat shields to come up with a bit of a "stealth plate" . Its not going to fool anyone who knows what they're looking at but would keep the daddy long legs a bit out of sight .

My side mount manifold was the very first one he's ever made. I had a deal in mind having them produced in quantity how ever the amount of time and parts required for this to work is far more involving then initially planed. It didn't work out.

Based on the manifold that I've received, bare in mind it was the very first one ever made. I score it 70% out of a 100.

Manifold does hold the turbocharger approximately on the same spot. which allows the factory dump pipe to be fitted as well as the water lines and drains.

The manifold pushed the turbocharger towards the chassis side by 25mms running that with an actuator and a standard actuator bracket becomes extremely difficult. How ever if external gate is used then that is no problems.

The bit I really didn't like was installation. Because it was all squashed together there are no room for tools. I had to remove factory rocket cover getting my spanners in, and skimm them so I can just turn the bolt. I don't think there are much can be done to this. But Once its installed its fine.

Performance wise it made more power then factory and any China manifold could ever reach based even running lower boost. How ever still fall 30kws behind his proper high mount with a 50mm gate.

Weighing up all factors, even tho it is a very good manifold, my vote still goes to his high mount with external gate.

what's with the crazy plate stack under the wg... cooling?

... is it just us Roy, but damn that looks cool!

I just machined out and re-welded my hks manifold. now I just need a motor to put it on :-) ... or it's going on the stagea.

Cheers

Legend01 (Pete) sold me on their merits years ago. He was doing his 2.3L when I was first doing my Greddy setup. I always preferred the HKS manifold for having a straighter exhaust flow / keeping heat away from the looms / easier to make good heat shields for / slightly more subtle / and the only cracks they seem to get is in the web of the split pulse flange.

With a black Turbosmart gate there is every chance that 90% of people wouldn't spot what is going on and the make engine bays look so clean.

Tone down the bling and it all looks pretty std

Good to see your getting it sorted! Hope it works well for you, was watching this thread ;)

      Potential MAP Reference Point

      By GTSBoy · Posted

      Getting a decent signal from all 6 throats is a challenge. I don't know for sure, but I suspect that the stock balance tube is not ideal for it. I have done it on an ALFA 4 cylinder (about 35 years ago, so don't ask for too many details). We drilled 4x holes in the manifold runners, put in some fittings and ran hoses to a decent sized (I think it was about 20mm diameter) pipe that ran the length of the inlet manifold. So, it was quite a decent volume. There is a "tuning" balance to be found between the volume of the common plenum on such a thing and the diameter of the pipes running from it to the runners. You need the volume to be large enough to damp out the sharp spikes in pressure signal you get as each runner gets sucked on by its cylinder, but not so large that it becomes too slow to respond to actual changes in MAP. And you need the hoses to be small enough to transmit the signal quickly, but not so small that they delay the signal. You might have to have more than one go at it, if there isn't any actual success based wisdom to be had here. Hopefully there is. Anyway, I would not do it on only a couple of cylinders. I would also not care about "permanently modifying a part". Just bloody drill holes and make stuff better. There is nothing sacred about any GTR unless it is a genuine museum piece that you shouldn't be modifying at all anyway.

      R34 GTT front hood lip

      By Kinkstaah · Posted

      The strange thing is this is a URAS front bumper (or clone of it). The bumper actually does not sit flush with the GTT hood - You need the addon to make the hood 'long' enough to reach the bumper. I have no idea why they didn't incorporate this piece into the bumper itself.. instead of sticking it to the hood instead.

      R34 GTT front hood lip

      Another thought on this OLD topic: When you paint your bonnet lip, leave a small unpainted back lip/line along the back of the lip, where it rests on the bumper. That way, the line in the back is much more prominent than the gaps in the front/under the lip - and it breaks the hood-to-bumper connection at the "correct" place, when comparing to a GTR. I'm gonna do this with mine this week, so stay tuned for pics!

      Potential MAP Reference Point

      By Radical_Goodspeed · Posted

      So I'm in the final stages of assembling my single turbo RB30/26 and had a question regarding MAP reference points.  I've seen several recommendations such as tapping the cylinder 2/3 ITB, tapping the intake manifold at cylinder 2/3, or using a point on IAC. First two are doable but require permanently modify part and the third is "out" as I plan to delete the IAC.  All that to say my question is can I used the "bleeder" in the center of the ballance tube as a MAP Reference? I'm running a catch can so I don't need it for the PCV system. My thought process is it "pulls" from all 6 cylinder, and it's between the ITB and the cylinders making it ideal for MAP reference according to what I can find. Thoughts?
