Quick survey for Jeep 4.2L/4.0L motor owners:


If you were looking to upgrade the performance of your 4.2L/4.0L would you be interested in adding an after market manifold to your Jeep motor that would add 25-30HP threw the concept of "inertia-supercharging"**?

Do you think $300 is ok for a 25-30HP upgrade?

Using a larger than stock carb/throttle body would add another 10 HP. Would you retain the stock carb/TB or move up to a larger one?

If you were to use carburetor, would it be 2 barrel or a 4 barrel?

If you get a new TBI, would it “bolt up” to your factory manifold?

DEQ/CARB questions:

How important is being DEQ legal in your application?

Would you pay an extra $40 for a manifold that would be DEQ/CARB approved? (4.2L/4.0L)


**inertia-supercharging: the kinetic energy of the moving air down the (runners that are separate and equal in size and shape) or ramming effect to trap more air in the cylinder.

Thank you for your time..

I didn't like the look of it. The runner length seemed mismatched. I got a 1999 intake off ebay. Like this one

Actually the all the runners are the same length. I should get a picture from Lloyd of the "dye's" to show equal length.. but anyhow.. thank you for your comments.

that would help

I have seen an article that I think Hesco :confused: is a company that races XJs in jeep speed. They get a 25 or so HP from useing an intake off a Grand Cheeroki 4.0. It is a different desighn than the XJ.
