ok frank thought might work coz stani said they same on holes and gap ? Or u mean coz iron casting ?that aint gonna work mate, the angles of the outer runners, and you wont be able to engineer any strength in the welds.
and a custom flange will cost mega-bucks eh
ohh yeh I get wat u mean now. Any other idea of getting a top mount frank
the steampipe fittings and tubby flange are easy to get, and weld, but the head flange is the problem part tho mate.
This I like, can double as a flange for a tubular if you feel like a challenge later onhow bout weld or bolt the upside down mani onto an adapter flange plate to correct the stud holes?
You cant get to the lower bolts then tho paulhow bout weld or bolt the upside down mani onto an adapter flange plate to correct the stud holes?
Yes I know what u mean frank, I have a idea of a startlet turbo top mounted one then cut the 4 ends off and make a manifold flange to fit k11 so it's cut and weld ? Will that work? Td05 is good frank my turbo kit is going so am gona do a t25 I thinkaye
and there,s no need for a top-mount T25, when a TD05 will fit into that gap so easily

That's a good idea but I think the bolts won't line up and will be lower then k11 flangehow bout weld or bolt the upside down mani onto an adapter flange plate to correct the stud holes?
You have one set of bolt holes that line up with the head and drill another set of bolt holes to line up with the upside down manifold.
can't I weld on the upside down one on the flange and flange bolted as normal on k11 mani
Yeah you can I suppose, but you wouldn't be able to make a tubular manifokd with it later if you did but if you're not going to do that it might be the best way.
I get it now ill see wat I can do
that's the point of this adapter plate concept (tis like converting a 4 stud hub to a 5 stud with a spacer)
ah the lower fastening on the "adapter plate" cos the pipes from cyl1 & 4 sweeps across and obstructs access with a socket.You cant get to the lower bolts then tho paul
I don't like the idea of having a short bolt. After the flange is on the engine?
Yes I will get plate made so I can weld it on my Manifold and bolt the plate on engine
I get it now the plate is my manifold and k11 manifold welds on my plate ?
Yes thanks
Polly that would help If u can draw me a rough picture thanks
Just sell pictures for £100 instead
polly I like ur detail work u put in for me and others to look at, it's what am gona do, I need to get a plate made then gona start thanks pollyshould as well cos this had taken me few hours out of my busy day to measure, check, assess, design and illustrate a simple idea to someone
k, assessment.
here's the mani
the gasket illustrates where the engine studs are with the manifold upside down
the lower studs here will be impossible to get a socket to cos of the pipe.
using a spanner here, I align the closed end to the stud hole
it clears the manifold laterally
but cos the pipe is so close, you won't be able to fit it over the nut
can prob use an open end spanner but only few degrees at a time
nut will sit like this far
for the upper nut, the nut and spanner will foul abit of the corner so this will have to be grinded down
so option A, welding the stock manifold upside down onto the adapter plate permanently and then fastening this assembly onto the engine head will not work cos you won't be able to get the spanner to the nut easily.
the better option B, is to fasten the adapter plate to the block first
and then fasten the mani to that plate via relocated studs on the plate that matches the upside down mani
new studs for upside down mani added to the plate
cutaway arrangement
That wants charging for that does. That's a couple of hundred quids worth of R & D and designing planning thatshould as well cos this had taken me few hours out of my busy day to measure, check, assess, design and illustrate a simple idea to someone
Then sell up and start a ct9?
