There really isnt any decent options on the market at the moment.

There is the usual ebay/chinese type ones which are cheap, and not exactly the best quality, but i wouldnt want one on my car.

The only real "decent" options are buying a HPI one from justjap, but there are very expensive at over $1000, they would be ALOT better made than the cheap chineses ones though, also Kazama make one similar to the HPI version but there are very hard to find and very expensive aswell

Apexi and HKS (i think Greddy/Trust make one too) make a cast low mount manifold for the rb20/rb25 but this dosent mount the turbo in the stock position so that wouldnt really be a good option either unless your willing to modify a few things, in the end the cost vs gain isnt really worth it with these two options.

There is another option which is getting your stock manifold honed/ported, a few people have had good results from that by what ive read, not sure to on cost.

The only other option is to get one custom made, which again will be expensive, i actually asked 6BOOST a while ago in a thread if he has anything/would be willing to make anything for a rb20/rb25 with the turbo in the stock position, he basically said no (if i can remeber correctly) i think his reasons were that it would be very hard to design/make one that actually fits in the stock position and would give decent gains as there is very little space to work with, you cant fit a decent collecter in that area etc etc.

So really there isnt mani options, unless your willing to spend a bit of money!

Im in the same position

Im thinkin bout going after market low mount cheap chinese manifold (can get one cheap)

atm just using the stock rb25 mani with kkr turbo

Want to go 4 my final tune soon down brisbane and not sure if i should upgrade the manifold?

Are the cheap manifolds prone to cracking under higher boost 18psi etc

Would i be better off keeping my standard cast manifold.

It has been proven time and time again that there is no benefit in running these china lowmount manifolds, if you need a lowmount, the only option worth considering (over a stock one which is fine for 300rwkw) is an HKS or Trust cast manifold.

hey guys, i have the HPI low mount and its awesome. it was over $1400 for it from justjap...so like wow expensive...

but i dont know about you but once you put new gaskets on, new studs/bolts/nuts/etc i wouldnt want to be taking all that off again...the labour is the big killer!

so do it right once from the beginning and you wont look back. with the HPI one there was no spacers or anything like that required. my hks gtrs fitted but beautiful. what you will need made up thoug is a BOV return pipe and a new intake pipe and they wont fit at all...

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
