carb .intake swap

[fiat218]

i got a 1800 intake , and im wondering in theses 2 picture what are the hose for on the end of the intake, theses are blocked off, so i assume they stay blocked,. the other is the electrical part on the bottom. what is it? what it for ? and do i have a wire for it, the engine that i am installing this intake is a 80 2000 /carb


now the other photo . there 2 hoses, what are they for and where did the other hose come from. i assumed it for water outlet? where would that go . or do i block that

You can leave everything on the intake blocked off. The large port in the center area you can use for the brake booster vacuum. In the second picture, that is the crankcase ventilation trap, from that unit a hose goes up to your original air cleaner, but with a 32/36 conversion you can get a kit that comes with the new air cleaner assembly to attach it to that. At any rate, you don't want to plug up the crankcase vent.

and what that electrical plug for on the bottom of the intake

[jsab]

Sorry, forgot to mention that thermoswitch on the bottom of the manifold. You can just leave that, or remove it and plug it with a M16x1.50 plug. No wires need to go to it, and it does no harm just leaving it there. If you do remove it to plug, use thread sealant to make sure there is no vacuum leaks around the plug.

ok thanks

[fiat218]

so, i have a 80 2000
i am swaping the ontake ,
can some one tell me what do do please. the intake is smaller the the one that on there so what do i do with this hole


what is that a water jacket hole ? or what

[narfire]

I believe that goes right through to the other side. Not an issue I think to leave it. If you have a FI ex manifold the hole is exposed that side as well. I saw this earlier this year helping Zach put a single plane and 34 dmsa on his 79.

[fiat218]

so what u are saying is that > the hole expose does not mean anything? and to go ahead and bolt up that intake and nothing will cover that hole or gasket? makes no sense, can some one show me a photo of this

[lanciahf]

It Depends on which exhaust manifold you are using. if you have a stock carb 79/80 exhaust manifold with an an extra tube connected to the front of the motor then you have to seal that tube.

Some people cut the tub and weld it shut. I have seen some tubes crimped shut.

Can you take a photo of your exhaust manifold near the water pump?

[fiat218]

here a pic of the exhaust



so being that tube is there? what about the other side where the hole is, that a exhaust too. i really am not understanding this yet
thanks for helping me , just what do i do? tight down the intake bolts then what about the extra gasket running past that and the hole ?

heres some pics of my 1800 head


i stuck a 6 inch long pick in there.it might port out to that cricle witch is coolant
you might want to copy this pic to see it all

[fiat218]

so i just plug them holes and continue with my 1800 intake on ths 200o engine?

[So Cal Mark]

that is the crossover port for the egr. If you still have the 79 exhaust manifold, you will need to plug that hole or remove the tube from the exhaust side

[fiat218]

oh , is that it, what about the gasket, i should order another gasket so it ends at the intake of the 1800?

[fiat218]

just remove it from the exhaust side and not worry about the other side ? got it
