what would be the best material to make a custom intake plunnum from????? mild steel, stainless or alluminium?

cheapo and doing it your self mildsteel
stainless and alloy if you going big and dont care about the price of labour etc.

exactly what I think A14 force, olskool = carbs, opening the bonnet to see efi on a morris minor is like seeing your granny in a mini-skirt. Just wrong.

LPG all the way. EFI is too pricey. Petrol is ridiculous

A clean oldskool looking LPG setup is very possible a very little challenge compared to injection.

Yes, but even highly polished, a mixer/converter is an ugly piece of kit.

Dead easy fix if you try
Just use a tiny Odyssey or cheaper Full River SLA AGM battery
you cut the battery size by 70 per cent then hide both the battery
and mixer in an alloy box with alloy separation between the two.
Cleaner and more beautiful than any EFI setup.
Datsuns made cheap and simple so keep them so.

wow! this is really interesting! alot of opinions flying around here! i can only speak from experience as i obviously had an efi manifold on my car. it made 150hp at the treads on 12psi. there was more in it! ask any experienced engine tuner and they will tell you that intake manifold design and capacity has less effect in turbo motors. there are gains but marginal. put it this way. i do not expect to gain more than 5hp on the same boost because of the manifold change.i am only changing out of necessity. the ports are too big.

about my particular manifold that is for sale. maybe people should read things a bit slower and to comprend what is being said and look at pictures in a bit more detail. the manifold is NOT modified, it has an adapter that has been build to suit the magna throttle body. you do not want the factory tb as they are junk. twin throte, holes too small. yes it comes with the injectors and fule rail. i just paid $700 for a fuel rail and injectors for my new set up... that is what it costs. sure you could buy some secondhand injectors but they would need to be serviced and that brings you close to new ones anyway. i am biulding the manifolds myself and so far in materials your looking at around $250-300 and that is with out any bends. that happen to be $40 a bend. there is no way you will build a manifold with fuel rail and injectors for less an $700! to thinking about biulding intakes manifolds out of anything other than ali.... please do yourself and your engine a favour... dont do it! there is a reason manufacturers use ali. it has a far superior heat loss efficiency rate. if you use steel or stainless you are just heating the air going into yur engine which will cause all sorts of problems.

ps. i thought those manifolds came out on atmo motors so shouldnt they work alright? just change the tb!

Back to the custom intake material...

I would make mine out of Aluminium because its light, and doesnt warp as much as stainless does when you weld it, but for me mainly it would be becuase it is easier to work with... Be careful with the Aluminium when your handling it cuz its soft and will scratch easy.

Stainless is cool too, I made my exhaust manifold out of it.

When it comes to cost, it dont really matter which way you go cuz both are freakin expensive nowadays.. S/S is more though.

As far as using mild steel.. forget about it, thats just a dumb idea.. all that rust potential to go in you engine.

If your going spend the money or time fabbing it you might as well use the more expensive material becuase the cost of material will be nothing compared to the cost of having someone build it.. and if your doing it yourself you want it to look good right..
