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

    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go       
    • I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
