So I was given these parts in payment for doing some work for a friend. I was bored this weekend and I decided to drop them on my B16A2.

Installation went great, but I have some questions on coolant line routing.

TB has two coolant ports:

#1 On the inlet side of the TB bent back and facing the firewall, I assume this one goes to the outlet off the thermostat housing?

#2 On the front side of the TB between it and the head I assume this goes to the right port on the bottom of the IAC. (Right assuming you are looking at the intake manifold infront of you.)


The IAC has two ports on it, the rigth one, like I said, goes to the port on the TB between it and the head, but where does the left one go?

I'd honestly like to eliminate all that crap and cap off what isn't needed, but I am not sure if that is possible.

The other problem I face is that the Edlebrock TB is setup for a MAP sensor to sit on top of it, while the stock configuration is different.

What are people using on here if they are running a different MAP sensor, as this is a huge vacuum leak?

 

Coolant lines should be just like the old IM and throttle body were.

IM > TB > IACV > Coolant pipe on back of block

If you want to get rid of all that just run a hose from

IM > Coolant pipe on back of block


As for the MAP sensor, you said you have B16A2. The MAP sensor should go in the same spot as on the old TB, unless this is on an ODB0 setup. Is it?

>>><<<

 

The MAP sensor the car had when I got it was one that was just zip tied up to the firewall and had the vac. line running from off the TB up to it.

On the Edelbrock setup:



The MAP sensor mount is at the top right of the vac. nipple.

 

I see a MAP sensor being used there, but thats not what mine is like, mine is alot bigger.

 

Ok, I can't get this F'r to idle at stock with the old TB and VictorX manifold. She constantly wants to idle at 2k.

I've plugged all vac. leaks I can find.

Could this be a problem with the IAC?

If you are looking at the IM, I have the IAC right port plumbed to the water outlet by the distributor. The left port is plumbed to the outlet port by the thermostat housing close to the breather box.

Thoughts?

 

You might need to adjust the throttle stops. Also check the idle screw.

>>><<<

 

All the coolant lines have been re-run properly per manual.

Set screw is all the way in, backing it out only causes the car to idle higher.

Unplugging the IAC causes the idle to bounce and throw CEL of course. Reset CEL and pull the TPS sensor, no change

With everything plugged in and line routed properly, car idles solid at 2k.

Thoughts?

 

What about the throttle stop screws. Adjust those to close the throttle more.

>>><<<

 

I'm not so sure this is a throttle stop issue, because if I rev the motor up and let it fall back, it will fall below 2k, almost down to a perfect idle and then creep back up.

 

you are supposed to set the idle with the iac unplugged.

 

Which I understand, but when doing so, the idle just bounces and movement of the idle set screw on the top of the TB makes no difference.

 

Are their block off plates available to eliminate the IAC and FIAV?

I assume some sort of resister can be used to fool the ECU that the IAC is plugged in.

 

are u turbo'd?

 

ATM, no, but going to be here shortly.
