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

      Yep, that was one of the things we learned fast in the past with our MX5. When you drive with the top down, you are effectively standing out in the sun, 100% of the time, and not getting in any shade (because roads aren't shaded generally!). Just like standing out in the middle of a field on a sunny 27C day is a bit of a bad plan, so is sitting in a MX5 without sun protection.

      I also just ordered some Frankenstein bolts and side mounts to fit a hard top Just in case I do find one, basically so it doesn't need to be fixed to the car with only the front latch.......and then gaffa tape to keep it in place for the RTN journey from wherever I get it

      If your temps are fine now, you probably won't have any issues with where your vents are as they don't look right up at the windscreens high pressure area, so any differences when giving it the beans for extended happy laps would be minimal, but, they should vent heaps when stuck in traffic  Much like how that reverse cowl on my SS let "visible" heat out when stationary, but, because it was basically at the windscreen my coolant temps on the Hwy actually raised because air was being fed into it at speed (110kph), to only come back down to around 90° when I got off the Hwy And your 100% correct about the NC currently not needing vents, but, if I was to add a turbo, and a oil cooler and intercooler in front of the condenserand radiator, and then take it to the track???? It is apparently a recommend requirement if I don't want to worry about coolant or oil temp issues, but, any of the above are possible scenarios, over time As it sits now, with the triple pass radiator and stock air conditioning system, I have absolutely no issues with either temps or air conditioning efficiency, I've been basically daily driving thie car for the last month, both on the Hwy, and peak hour, bumper to bumper traffic, but, that's pretty much expected from basically a standard engine  Talking about no issues daily driving, it was 39° the other day and I was sitting in bumper to bumper traffic on the M5 and then M7, with the top down, and with the air conditioning blowing nice cold air on my feet, balls, and face, well, there was one issue, my head and arms got pretty sun burnt Note to self: leave a hat and sunscreen in the car for such days 🤣

      I would agree, unless you need something specific to the HV motor/battery side repaired or investigated, any mechanic will be able to perform normal services, but if you prefer, maybe look for a mechanic who regularly services/repairs Nissans, the VQ engines are pretty common in the Nissan lineup.  Sorry, I can't make any suggestions, I don't live in Vic.

      Some of them keep working fine. 9 out of 10 of them end up causing an absolute misery bleeding the system and get thrown on the workshop floor in a tantrum and never thought about again because they were never really needed and just added crap to the car that we could have done without. Same-same with HICAS, A-LSD, and various other stupidities that over eager 10x engineers thought we had to have.
