I was using a ebay manifold of the same design. They foul on the hose near water pump outlet. It will eventually burn through the hose. I placed an insulating pad between the manifold and the hose but it was dodgy. Eventually went back to the cast iron manifold.

KL Racing suggest the welding of an aluminium extension pipe onto the water pump. This requires both the removal of the water pump and the welding process. I thought about using a pipe bender to create more space. But the cheap manifold was beginning to crack anyway so I didn't bother.

It may be a good idea to co-ordinate a group buy to generate economies of scale. If someone was making up 10 custom manifolds i expect the price for each would be much cheaper and there may be more competition for the job.

That’s great info mate, thanks for letting us know. I might ask around with fabricators in terms of doing a group buy.

I've been looking at these diy kits from treadstone for my 3sgte

    Steam pipe bends can be purchased locally. The only fittings that may need to be purchased is the flange and 4-1 collector.

    I just got a custom T3 one made at a local fabricator. I didn't ask about getting more made at the time but I could ask. I thought it might get murky with different turbos and wastegates etc. making fitment issues.

    Adaptors can always deal with fitment issues. Looks like quality work.

    I would consider shrouding those brake lines

    For sure. Those pics were taken during but now there's wrap and shielding for the poor clutch and brakes.

    This workshop also make different sized CNC merge collectors (T3, T4 etc. with or without a gate) and a fancy redblock 8v manifold flange if you wanted to weld your own. It blends from the square 8v port to the round tube. Too nice for my car but they made it anyway.

        Lovely! What do they charge for the nice machines flange and the collectors? All up price for what you have up to turbo hotside?

          I loved having the turbo forward and up. So much easier to work on. If we can get a manifold at a reasonable price i am all in. The KL racing upward and forward manifold is 2395Kr ($376) and their 8v Extreme T3 is 3895Kr ( $612). I think something of quality in the range of $700 would interest many.

          Add in around $90-120/Hr workshop labour. Treadstone kit at maybe $AUD350 (+ postage wouldnt be cheap) not sure of local prices for parts.

          The aforementioned $1200 may be about right , quite a bit of welding. Cost of CNCed flanges and collector fabrication etc , gas and consumables. Quicker with a top of range MIG than TIG with same result on quality. ($12K MIG......)

          Exhaust shop may make cheaper as hourly rate less, back yard fabricator as well.

          Economies of scale don't really count , only getting machined parts but the setup costs take away any benefit on say a dozen units. So you won't get cheaper on a group buy. It seems the fabrication shops still in business after pandemic are flat out so they may not even want the work.....

          And also quality counts, because it is schedule pipe it needs decent welding , sure a handyman can do it but may be hit and miss as there are tricks learned about pipe welding as you can imagine...

          The constant heating and cooling stresses the welds as can be seen on the cheap ones failing and the standard manifolds cracking in time so don't think paying less is a good thing when later it costs to pull it out and get it repaired......

            I'd be in for a top mount turbo manifold if there's a group buy.

              serk

              I'd be in for a top mount turbo manifold if there's a group buy.

              Looks like @GingerNinja s workshop guys have it sussed, see if they want to do a run of them , as I said, group buy cut price really isn't a thing on short orders as setting up for different flanges etc is a pain and nothing is done quicker , you just shortchange the owner.....So they may say fowgedaboudit as plenty of customers will pay good price out there.

                I am looking at an exact copy of the KL Racing upward and forward with an additional bend so that it does not foul on the lower radiator hose. I may have my old ebay manifold around. I could take that around local fabricators to see how much it would cost to replicate using proper steam pipe bends.

                I spoke to them today about making more but they're a bit scared to do it without the car to check fitment. Sometimes things weld up a bit different and this was all hand done. I didn't ask about a full manifold price but I'll see if a run could be done on my car as it's still there. Price would be more like $1200+ though based on conversations with them before they started.

                The CNC 8v flange is $310. Waiting on a price for the merge collectors. I've seen flat laser cut flanges on here though for $90 so you might save a bit there.

                This whole manifold thing kicked of when I took a used eBay one up there they said it was too thin and cracked and sh!t haha. Making a better one got out of hand pretty fast.

                Sure a pre cut flat flange is good but then can deform like fvk when welding on some pipe......

                What you had made for a fkn bargain is a bit O art and makes the welding so much easier.

                So , this scenario , i weld onto the shit thin flange and it pulls like fvk so i spend 3 hours @ $110/Hr fixing it ad it will still not be flat enough without machining.

                Get a HD flange......

                  Yeah I agree. They have cut out a few fancy 8v flanges if anyone wants one. They're ready to ship. I think they'd rather sell the CNC parts on their own, not a full custom manifold. Less headaches for them. I'll try to change their minds.
