Trying to find a suitable 5.3 for a turbo conversion on my Regal. I've found DBW and DBC engines for sale. Here are 3 examples I've found so far.

1) 03' 5.3 DBW complete all accessories, ECM, Harness and Pedal 118K $750

2) 07' 5.3 DBC complete with accessories NO ECM or harness 27K $800

3) 05' 5.3 DBW complete accessories, ecm, harness, pedal 59K $1000

Does it matter if I get a DBW or DBC if I get the pedal with the DBW?

TIA

 

I would go with # 3 simply because it is the lowest mileage of the two complete setups. With #2, you will have over 1K in it after getting a pcm and harness.

 

Are you sure the 2007 was drive by cable? What was it from?

I agree, I would go with the lowest milage engine. You can make any of them drive by cable if that is what you want to do.

Good question. What newer ecu will support DBC?

 

I don't know the answer, but here is some guidance from LT1Swap on how to tell.. http://lt1swap.com/cable_conversion.htm

I converted my 01 to DBC, the ecu had the driver chip..

The 411 red/blue PCM (1999-2003 varies by vehicle platform) can be programmed for either drive by cable or drive by wire. There are a few green/blue PCMs such as those from 2004 GTOs and 2003-200?7 Express vans that will work also but those were only 5.7 and 6.0L respectively you would have to tune more stuff for a 5.3. I would stick with the 411 red/blue if you are going to use drive by cable.
