Intake manifolds

[rbsileighty]

What is really needed on an intake manifold (upper and lower) as far as upper and lower manifolds are concerned? I noticed the lower manifold has coolant pluming by the head on the 20, do 25's have this as well?

For all of those with Greddy intake manifolds, what was discontinued from the 25's original manifold? The only sensor and connection I've seen carried over (that I can observe without seeing it in person) is the IAC is switched onto the new manifold.

What happens with all of the cooling lines?

If someone could post some detailed pictures for the Greddy 25 manifold, that would be great!

That is exactly what I was looking for, thank you very much!

All water lines and All IAC and Air bypass parts are moved over to the GReddy.

Yes, thanks, I saw that in his pictures. I'm thinking of making one or having one made, and just wanted to look into what was carried over. I had an idea, but I was not sure. I am very unimpressed with what is currently available for the 20 as far as intake manifolds are concerned.

the probelm is low quanitys for some one to go and build some thing nice and doing it for a price that NISSAN buyers will pay. There are lots of good manifacture out there but they want $$$ and min quanity.....

This is definitely a factor I understand, which is why I'm looking into making one myself.

It looks like the best way would be to use the stock manifold flang and add new runners on to them. I guess you could get the flange made but it looks like alot of work to make it work like a stocker. I too am in the same boat as you lol, I might just modify the stock one since I have an extra one now . Any Idea how whats a good length for the runners? I know if it's too short it will be for mad top end powa.

http://WWW.UNIQUEAUTOSPORTS.COM HAVE A COMPLETE INTAKE MANIFOLD INCLUDING UPPER PLENUM, LOWER RUNNERS, COOLING LINES AND EVEN A FUEL RAIL.

Who knows, I might just break down and buy the upper from tophat. That would at least last long enough until I figured out what I want to make.

you have a pic of the tophat one?

RB26 surge tank would be nice http://s92978298.onlinehome.us...ic=28

Check it out! I wrote tophat about their manfold and asked if they were going to make a full upper and lower setup. Well they are making one!

link says forbiden... repost it somewhere please.

that isn't the pic of it right? cause it looks like there upper manifold and stock lower.

[rbsileighty]

Don't worry about the pick, you are right yellow. I guess the 103 temp I had last night was getting to my head. Stupid flu. I looked at it more closely today, and I agree it is the stock lower. I was just fooled by the paint, stupid paint.

RIGHT NOW THEY ONLY HAVE A UPPER PLENUM AVAILABLE.
