Air box/intake for LS3 engine
« on: January 05, 2019, 03:41:37 PM »
Hi - I’ve decided to go with an E-Rod LS3 (6.2L) in my 77TA.

I’ve gotten most of the swap parts figured out except the air intake.  From talking to my Bureau of Auto Repair, to be legal, the box needs to resemble an OEM box similar to one on the gen 5 Camaro.  I’m pretty sure that box is too big to fit in a 2nd gen however.


Any suggestions on what to use?  Does anyone sell an out of the box setup that works?

Thanks
Darryl

I think he just meant for it to be in the boxed type of style that's in the 5th Gen Camaros. 

There are a lot of CARB legal air intakes out there...I'm hoping that as long as I've got one of those I should be ok. 

Either way it'd be good to see examples of what folks have done to fit an air intake system in one of our TA's.  I wasn't able to find any when searching TAC and LS1Tech for them.

I thought that was the whole point of the eRod engine was that it was 50 state legal as is? If you have to go through the trouble of making it resemble a 5th gen Camaro, you might as well save yourself a bunch of money and just get a low mileage takeout motor.

To be specific the Bureau of Automotive repair guy said that it should be "stock" in appearance.  Not 100% sure what that means exactly.

The instructions in the E-Rod guide give the following direction - I believe as long as I follow these I should be ok.  I thought it would be good to use a CARB legal Air Intake that meets these requirements (and fits obviously). 

Ensure the MAF sensor is oriented correctly in the induction (it
will only read correctly in the proper direction). An arrow is located
on the sensor indicating correct flow direction. Verify this before
welding the mounting boss, as the sensor will mount only one
way in the boss.

Ensure the MAF Sensor is mounted in the middle of a minimum
6 inch length of 4 inch diameter tube, and is a minimum of 10
inches from the throttle body.
