Seeking help on Vortec intake plumbing (1 Viewer)

[Cirbo]

I tried the general FJ40 group and got a little data, but I thought I'd give you guys a try as well. I have installed a 5.3 Vortec into a FJ45. I will be using a Ron Davis radiator and conventional (18 inch) fan with a shroud. I'm seeking input on the tight confines of the air plenum (about 3.5 inches clearance) to the throttle body. Has anyone done the footwork on this part? Any good solutions? Can anyone ID this plastic piece?

Input from others puts it from a 2007 Tahoe?

TIA,

Jim

Looks like it fits pretty nice, no??
What's wrong with it?

I had ONE OPTION and it was a cobra elbow. Saved my ass!!

 

[Cirbo]

Chicago, was your cobra the same as this item?

Cobra Head Elbow 4" ID: Intake Hoses, IntakeTubing, and Intake Clamps

If not, where did you find it?

The other possible find was this:

But it's a little more of a stretch.....

why not run the stock GM air cleaner setup? I know on my 60 I get mud and crap all under the hood.. I know its a different engine but I run the stock GM air filter assembly on my 5.7 vortec.

Cirbo I got the Airaid-200-912 in my FJ60 with a 5.3
It is a cleaner set up but with the cone style airfilter I get to have about 1" clearance on the fender.
If you will be running a mech fan it will get on the way of the fan or shroud.
I run an electric fan so no worries there....
check out some of the other builds in here for pics on what others have done....

Nice clean conversion you got there...

That's the one.
My motor is pretty far forward, so that was my ONE AND ONLY OPTION.
tried pretty much all of the off the shelf intakes they had at summit, and none of them would make the 90 off the intake.

That one is the s*** if you can fit it!!
It looks super clean.

Another option for the 5.3 is to unbolt the intire intake and rotate it 180*. It is all modular and will work both ways. That way the inlet is at the back of the motor. I alost ran mine that way. Am running a snorkel with a universal inline air cleaner from Spectre Performance.

Can you share pictures of this set-up?

That airaid intake tube looks like a good deal - if you can make it fit. I ended up using a short radius 90 to the MAF sensor, then this slick flex tube down to the air filter:

I had an original airbox that I thought of using, but there's no way that monster was fitting anywhere under my hood....

Glad to see more 5.3 swaps! I like mine!

So, after posting the pic, I guess you can't see the filter... Try this one:

Just to clarify, the picture at the top of the post is not my truck. It is of a FJ60 series engine compartment. My WIP is a '67 FJ45.

Looking at the other installs, I think my motor is pushed up closer to the front than the other examples. I had considered reversing the intake, but doubt it would increase the amount of needed space.

Thanks to all for your input.

Kind of on topic, where are people getting the flex tube? I'm thinking about just using the cobra head with a little flexy tube then a cone. Do you think there is much risk of water getting in?

The cobra head is plenty flexy!!
I actually used a PVC elbow to connect the filter to. I was worried about it, but it seems to be doing just fine.

I don't know which part of Oregon you're in, but if around the Willamette Valley, got to Western Tool Supply. There you'll find plastic flex tubing, much tougher than dryer vent tubing, that is used for vacuum dust control systems. The common sizes are 3" and 4". I have used the 4" for air intake on my 83 Chev diesel pickup.

If not close to a Western Tool store, any place that stocks woodworking tools and machinery should have, or can order, the tubing.

Thanks Don I have one just a couple miles down from my house. I'll look them up.

 

[boysrus]

Nice 45!

I got my flex tube at summit - link is in my first post. It is definitely much more substantial than dryer hose.

I like the intake "cover" you have now.

I need to track down some more pics of your build.
