I'm starting my build on my 1.6 n/a.I was looking at the intake on it and it kinda looks inefficient the way the cold air is directed into the motor.I was thinking of eithier cutting the ducts out completely or maybe just drilling holes in them so the air gets into the motor faster.Anyone tried any modifications to their intakes?
-
One of my customers has gills cut in the right fender of his GTi. I asked him if it made a difference, he didn't notice any performance gains from the gills. ;D
-
you can use 4" intake piping..wont hurt a thing..
-
you can draw your intake air from the rain tray. OR if you're really savy cut a hood scoop in the hood right above the intake (like on a subaru) and have the intake filter housing mate with the hole you cut in the hood with some simple fabricating. Rivit some alluminium sheet metal to the filter to raise it up to the hood (that extra inch or so you need) and weather strip around both the hole in the hood and the intake riser you make. it would obviously take more thought that that but... ::) ;D
that would be really cool to see :P
I bet at highway speeds you'd actually have possitive pressure in the intake. i'd go as far as to say even 1-2psi.

Ed, just going by his user name, im gonna assume this engine is in a Samurai..
-
oh yeah ... didn't notice that :P was too interested in the subject matter.
but no matter, you can still do that in a sami =D
-
Ram air is the plan guys but I'm talking about the inside of the intake behind the filter. The air has to go up and all the way down the ducts into the head. I'm gonna try cutting the ducts completely out so the air doesn't have to travel all that way to the engine. By the time it gets thereits already warmed up.
-
OOOOOooooooooo I see what you're saying. You want a more efficient manifold from the filter to the ports of the head. I see i see. WELL you can run any intake from almost any 4 cyl engine on there. Some have O shape ports and others D shape but with a tiny bit of porting with a dremel or even a file you can make it work well.
If you've got the skill and equipment to weld alluminum you could make an AWESOME intake manifold for your NA from a p190 intake (or what ever its called - the huge thick one)
-
P190 intake? What are they off of?
-
the newer TDI's. I think its P190 ... there are a couple variations. They are from the PD engines... maybe its PD190?

here is one
augh work blocks most of photo bucket so i can't copy the links ... thisi s getting to be very annoying..
here go to this page

that is one
here is the link if that didn't work

anyways, they are the best intake in my opinion. Big runners! but clearly designed for a turbo application so maybe if you cut the top of it off and made some sort of air box for it that mated to the hood and housed a filter?
-
I have a 1Y intake and snorkel that will bolt right on

gasoline intake manifold will work too, and if you get a mk2 manifold, the inlet will be faced the right way. then you can run a cone filter, instead of the huge paper filter.
-
A K&N cone filter, just because OM617 hates them ;)
Ed, do you mean a PD150 intake??

Stupendously Awesome!
-
Stock paper filter is much better than any cone filters in our power levels.
-
Hey 8v of fury what year of car is that one off of? It's awesome!

see the intake ports on that manifold? how they are shaped like a "D"? your 1.6 ports are ovals.. its gonna flow like crap if you put a d port intake on an oval port head. thats why i suggested a gasser intake manifold.. oval ports to match the head.
why are you guys showing him all these AAZ/tdi manifolds that dont have the right ports? why not show him something that bolts on, and doesnt need an AAZ head to make the intake flow right.. (or port the 1.6 head to D ports, but a gasser intake would yield the same results on a stock engine, but would be 10x easier to do. just bolt on and go..
and this PD 150 intake is off a 07 or 08? pump deuse TDI engine..
-
Porting an intake isn't a problem I have the technology to do it
-
no no no.. you got it backwards..
the intake has D shaped ports witch are bigger, and differently shaped than the oval ports on a 1.6 head. you will have to turn the oval ports in the head into D ports to get the 1z, or PD 150 intake to line up correctly and not be a flow restriction.. but you could just bolt on a gasser 1.8 vw intake manifold on and do nothing. its not like you are asking the manifold to flow 200 hp worth of air.. the gasser intake will bolt on with no port modifications, and will be a HELL OF ALOT CHEAPER than a 1z or pd150 intake setup.. gasser intake manifolds are way plentiful. almost every mk2 car had one..
either spend alot of coin on a intake with D shaped ports, and then port your head also.
or bolt on a cheap gasser intake and hook up air plumbing and filter to it and be done..
basically any gasser 8v intake manifold will work. but the mk2 unit will be pointing the right way for your suzi conversion.
-
it takes two seconds to port the manifolds to match with the correct gasket as a template.
a gasser intake makes more sense. i was just stating what i would do :P

Stupendously Awesome!
Except its junk. Cylinders 2-3 get all the air rammed into them, 4 gets some and 1 gets whatever is left.

tis the truth.. it biases 2-3 badly.. those PD and stock TD manifolds. n/a diesel and gasser manifolds are alot less susceptible to cylinder biasing..
