G'day peoples, I'm interested in anybody whos made up their own manifolds.

High mount/ low mount, whatever it may be.

Just looking for an aftermarket manifold and really not satisfied with their shape. The only shape I liked was this HKS stainless tubular zorst that I saw on ebay for about 1600 bucks :D. Even that looked like it could be improved, maybe you have a bit of a room issue under the bonnet of a Skyline.

Mainly interested in a manifold suited to a high powered RB20DET, so if you are willing to share some info on the ideal manifold, made one yourself. I'll pass on my thoughts as well.

Cheers

Turbine.

the best exhaust manifold I have seen for RB20/25's is the GTSR Group A from Nissan. It is equal length, exceptionally well made and utilises the superior (for circuit racing) low/rear mount. A true work of art.

Not a good picture, I have better ones somewhere, I'll post them up later.

:( cheers :(

were can those GTSR manifolds be picked up?

R31House... or 2nd hand.

Considering there are only 800 original item... which i dare say a few have died...

2nd hand wont be easy.

R31House want a small gold mine for thier replica's unfortunately.

Thanks for the feedback on this guys, no doubt I'll be able to source out a manifold from all your replies.

I've only ever seen the GTSR exhaust manifold once in my life at a car show in Melbourne and I had my eyes glued to it for about 30 minutes checking it out. Real nice.

Still, I'm looking for the the one that follows the exhaust port angle with no bends for at least 2" out of the head.

I'll gather up some pics of the setup once I get one bought or made up.

Talk later guys

holy crap, no way that would fit in a lhd s chassis!

looks like its a pretty advanced manifold especialy for the time.....

wonder what a new technology turbo would do on a rb20 equiped with that manifold.

Yeh it would fit just fine. Remember our car has no inner gaurds. I could afford to have the header pipes longer than that still.

Could well have been my one?

Or the one from Rons old car which went to SYD :D

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
