this diff stuff is confusing lol

Yep better stick to the inlet manifolds! :)

these are billet machined Im sure you can do it!

yes you can do it!

yea thats what i reckon lol i'd be super keen for an intake manifold

Just to give you an idea HyFlo

look at any oval port manifolds whether stock or for sidedrafts they all sell and command good $$.

something like these will sell especially if you can do them out of small billet pieces to save costs and keep things small.

i need to get my HANDS ON A OVAL port a12 lol my ute never came with a motor :'(

Not sure what Subaru use but I would imagine it would be the larger size. as the smaller R180 would only have been used in the earlier Datsuns.

just use a flange HyFlo otherwise a gasket and just add material say 1-2mm can be just right for porting.

D is onto something ,those manfolds would sell like hot cakes ,and make it heaps easyer to make a plenum up for turbo aplications

should make some motor bike manifolds to suit r1 carbs :D to suit an a10 head then ill buy a set !!!


good work!

Don't hate me just consider me the devil's advocate......
I'm just asking the obvious questions that one would ask if wanting to buy these or research if there is a market to sell these to...

I don't get it? what are you going to put on the end of these manifolds?

carby turbo is a world of hurt, don't bother

so if it's for injection it will need injector bosses

plus why ask hy-flo to make it if you already have picture of one someone else is making?

plus making the plenum is the hard bit not the runners, so if people can make their own plenum for it i'm sure they can make the runners

plus i don't think there is a large market for this, carby's wont fit on the end and will be hard to support, injection is way more money than most are willing to spend

carby supercharger works well been in plenty of them now
There is a professional installer of superchargers with
a mightyboy 660cc using an SU like for most of his customers
and there are no issues goes like stink day in day out.

carby turbo works if you know what your doing most dont follow through with a full dyno or have the time. Lots of little things like water/meth injection are not implemented and there are plenty of carb A series that have worked in the past. Not to mention there are tons of A series minis running all over the world with inferior cast iron heads doing it and doing it right.

The "runners to the inlet ports" are THE HARDEST to manufacture, make or produce from scratch, to weld a bit of pipe on the end of these to suit is plain jane easy and takes alot of the headaches out of the equation.

To tap some brass injector bosses is also easy facing the ports.

To make a dual downlet plenum just as easy once you have the flange.
