Thread: What throttle body on Holley intake?

  1. #1

    Default What throttle body on Holley intake?

    I'm ordering a stock remanufactured 5.3L and I want to put a Holley intake on it. My stock one is nasty inside and out and I just like the looks of an aftermarket intake. I have a Terminator ECU/harness to go on it, but I bought it for DBW since that's what I currently have. But all of the Holley throttle bodies I see are cable driven. What are my options? I'd rather stick with DBW if possible. Thanks.

    Do you have the Terminator X Max? Is this a Gen 3 or Gen 4 engine? Andrew

    Yeah, X Max with DBW and no transmission control, Gen 3.

    I'd pick any number of Holley intakes that accept a 4-bolt Gen 4 TB. Look in the Terminator X Max install guide for approved part numbers. For a 5.3L, I'd choose the slightly smaller 87 mm truck TB. Look up 2009 Colorado truck with 5.3L. Andrew

    So I can use a stock 4-bolt TB off a Gen 4? I don't need anything fancy, I just mainly want to me able to use a Holley intake.

    That's correct. The list of approved throttle bodies is in the manual. Andrew

    Sorry to keep on, but all I can find is there on the page it says, "Designed to work with GM Throttle body P/Ns - 12570800."

    Download the instruction manual. It's in the link you posted.

    OK, I found it. It seems to work with most throttle bodies, but it says my kit comes with the early truck DBW harness, which would mean I could only use a 3-bolt TB. Looks like I may need to just send it back and swap it for another harness and go back to a cable driven TB. I wish Holley had a chat feature, I've about give up trying to get someone on the phone.

    Did you already buy it? I'd exchange it for a kit that uses the Gen 4 DBW TB. It's just a matter of a difference in the DBW harness. The ECUs are all the same.
