BA turbo engine in BF body?

[kcartere]

hey just wandering if anyone could give insight how id need to go about putting the turbo motor from a 04 BA into a 07 BF body. will the looms need to be switched etc

[k31th]

swap all electrics and all driveline, that's your best bet... there's a few minor difference that make it a bit tricky otherwise (mostly the electrics)

Install another knock sensor at the rear of the engine to suit the 07 loom and tune, and that's about it. Barra engines are very interchangeable and most of the time there is only knock sensor stuff, vct tuning, minor ignition and fueling adjustments and oil pressure switch tuning etc. It's the manifolds that create installation headaches as they don't line up between various models.

[kcartere]

so your telling me its doable without completely changing the looms?

 

im basically just looking for the most straight forward, least fiddly way to do it provided I have the entire 04 BA xr6 turbo and an engineless NA 07 BF xr6.

The cars are nearly identical, there is no point swapping any wiring. Make sure you put that extra knock sensor on though or it won't run properly under load.

But will the BA ecu plug into the loom on the BF?

[Puffwagon]

You only asked about the engine, not the pcm. What are you actually wanting to do, if not just swap the engine per your original post?

[kcartere]

yeah sorry if im being unclear basically my question is when I put the turbo motor on the car Im assuming the Turbo ecu needs to go with it because the NA ECU doesn't have the plug that goes to the electronic boost control, so my question is will all the Plugs from the BATurbo ECU connect to the BF?

Yes you can use the turbo pcm, in which case you don't need to worry about the second knock sensor. Only bf onwards have 2 knock sensors. You will be better off using the 3 plug harness for the turbo pcm, if it is available to you. You can splice the boost control plug into a na harness if necessary. There is nothing that won't plug in, no matter which way you decide to go.

 

You will need to link the turbo pcm to the car,  and possibly the trans if it has a zf. This can easily be done with Forscan, you can get a free trial of the extended licence to do this. I'll talk you through it when it's time.

 

Alternatively you can use the na pcm and just use a boost tee or electronic boost controller from GFB or Turbosmart etc.

 

After this and before you license the pcm for tuning, you will want to choose a suitable strategy for fully independent cam control, as the ba turbo pcms don't have that, unless it is a BA f6 pcm.

Both the BA and BF have the 4spd so I don't think ill run into issues there (correct me if I'm wrong). And as for the 3 plug harness, how big/straighforward of a job would it be to switch. I'm trying to find out as much as I can before asking but haven't read or seen anything specifically about that either
